Construction of a sturdy greenhouse using metal drywall profiles

Advantages of using metal profile for a hotbed

Metal drywall profile is the optimal option for building a hotbed. The material has a low price. Almost anyone can handle the installation, as the profile is easy to cut and bend. As a covering, it is recommended to use polycarbonate, as it allows for creating favorable conditions in the greenhouse for growing crops.

• Assembling the structure is cheaper compared to ready-made greenhouses.
• Installation of the material should not cause difficulties. If necessary, the greenhouse structure can be dismantled during the winter period.
• It is recommended to make the roof detachable so that snow does not load the structure during the cold season.
• The frame is installed on a foundation, which provides additional strength.

Before starting the installation, it is necessary to decide on the shape of the future hotbed. How to build a greenhouse from polycarbonate and profile by yourself? After the shape of the future structure is chosen, you need to select the right place for it. This takes into account illumination, as well as the direction of winds.

During the purchase of metal profile for drywall, you need to try to bend it. If the material returns to its original shape, it is of high quality. Otherwise, it is not recommended to buy it.

It is also necessary to consider which version of the hotbed will be assembled: summer or winter. Specialists recommend making the first structure as a summer version. If necessary, in the autumn, you can install heating in the greenhouse room.

At the next stage, you need to prepare a drawing with all dimensions. When developing the design, you need to consider the dimensions of the polycarbonate so that you do not have to get rid of the excess.

All materials are purchased according to the prepared project, with a 10% margin. To erect the structure, the following materials must be prepared:

• Metal profile.
• Cellular polycarbonate.
• Self-tapping screws.
• Necessary tools.

Foundation preparation and frame installation

Experienced masters claim that a hotbed made of metal profile can be assembled in a few hours. However, it is recommended to increase the reliability of the structure. To do this, several steps should be taken to prepare the foundation:

• Dig a trench around the entire perimeter, the depth of which does not exceed 0.7 m.
• Fill with gravel and sand by 10 cm.
• A week later, remove the formwork and wait another month before assembling the frame.

Some gardeners cut the metal profile with an angle grinder, but in this case, the edges will be damaged, which will lead to the appearance of rust. Therefore, it is best to use special cutting shears.

The metal material needs to be cut in advance so that assembly does not take much time. The end part of the future structure should be assembled on the surface of the ground, using ordinary self-tapping screws to fasten the profile.

You also need to install the door on hinges and assemble the rear end. At the next stage, the arches are attached to the driven-in metal rods. When the frame is ready, you can start covering it with polycarbonate. You should start with the roof, then proceed to the walls, and finally to the installed door.

A utility knife is used for cutting sheets to the required size. It is recommended to seal the cells with tape. Polycarbonate is laid with an overlap and fixed with thermal washers.

Features of constructing a hotbed from profile

If you correctly carry out all the stages of erecting a structure from metal profile, you will have the opportunity to harvest several crops of fruits and berries. You need to bring in soil, make beds, lighting, and, if necessary, install a heating system to use the hotbed in the winter season.

Advantages and features of plastic pipes

Today we will examine in detail how to build a greenhouse with your own hands using plastic pipes. The material is convenient for creating a hotbed, even an arched shape. In addition, corrosion can be avoided.

Soon the time for seedlings arrives, so you need to think faster about equipping the greenhouse room. This will allow harvesting all year round, provided that the structure is carried out according to all the rules. Therefore, I recommend studying my review on making a hotbed using plastic pipes. Photos and videos can be seen in the article.

The pipes are easy to cut; no special equipment is needed for this. At the same time, the connections will be durable.

Such a hotbed is very popular because it has many advantages. Every gardener will be able to cope with this task. Even the drawing can be done independently. The light weight of the structure eliminates the need for a foundation.

Many gardeners make seasonal versions, that is, they cover the greenhouse with film, remove it for the winter, and cover it with polyethylene again at the beginning of the season. In this case, the frame made of plastic pipes does not have to be disassembled.

The main advantage of plastic pipes is that they are corrosion-resistant and can serve for a long time.

Rigid plastic pipes are used to construct gable and single-slope structures. They are fastened using couplings or polymer tees. The structure can be covered with polycarbonate or polyethylene film. The use of glass is not recommended due to the heavy load on the greenhouse.

Construction of a polycarbonate and pipe greenhouse

When building the structure, the following points must be taken into account:

• No experience, qualifications, or special equipment are required.
• Mobility, i.e., the structure can be moved to another location.
• Possibility of using any covering material.

Plastic pipes make it possible to build a hotbed of any shape. It can be covered with polyethylene film.

To build a greenhouse, preparatory work must be carried out. First of all, it is necessary to determine the correct dimensions, as well as the location of the future greenhouse. The area needs to be as well-lit as possible, and the height should be at least two meters.

Construction of a budget hotbed from plastic pipes

If it is intended to cover the structure with film, the following parameters must be taken into account:

Now, let's proceed to the construction of a hotbed made of plastic pipes. PN 20 material is used; in addition, it is necessary to purchase PN 32. The first option is cut into 3-meter lengths.

1. PN 32 needs to be cut into 30 cm lengths and driven into the soil at a distance of 80 cm. To prevent soil from clogging the pipe, one end should be plugged.
2. Insert the arch pipe into the pipes already set in the ground.
3. The material can be fastened using ordinary tape.
4. In the final stage, prepare the polyethylene film and cover the finished frame.

The video will help you understand all the nuances of the assembly. It will take about two hours to build this type of greenhouse. This is a budget option that is accessible to every gardener.

DIY profile pipe greenhouse

Greenhouse made of 20×20 and 40×20 profile pipes. Blueprints and photos of DIY greenhouses. When you decide to build a hotbed, the first question that arises is: what material to use? In this article, I decided to provide an overview of building a greenhouse yourself using sturdy profile pipes. With their help, you can make a reliable frame that will last for many years.

On the internet, you can find many tips for assembling the structure, but most specialists describe the manufacturing process using standard pipes, not profile ones. It is necessary to understand that a profile pipe, unlike its traditional counterpart, has a rectangular or square shape.

Despite its low weight, this material is quite durable. If an arched greenhouse is planned, it is recommended to use a 40×20 profile. For crossbars, a pipe with dimensions of 20×20 is more suitable.

• Large selection of covering options.
• Simple fastening.
• Easy assembly.
• Possibility of making a structure of any shape.

The only difficulty might be bending the material. In this case, you need to accurately bend one pipe, and then use it as a template. Before doing so, it must be filled with sand. We are making a DIY greenhouse out of profile pipes and polycarbonate.

There are several types of hotbed shapes, but I decided to focus on the arched type. If you have basic skills in such work, you should not have any problems with the assembly.

When choosing a place for the future greenhouse, you need to consider maximum illumination, so it should face strictly south. Surface irregularities should not exceed 10 cm.

To make the arches, prepare 10 pieces of 20×40 profile (profile pipe). The approximate length of the pipes should be 5.8 m (you can have them cut when purchasing, or buy 6-meter pipes). To form the bows, it is recommended to use a pipe bender; if done by hand, it will be difficult to achieve high precision.

For the frame crossbars, prepare 40 pieces of 20×20 mm profile. The pipe length is 67 cm. Use pegs and string to mark out the future structure. To ensure an even structure, check the layout diagonally.

Dig a pit to a depth of 80 cm, then fill it with cement mortar up to the level of the longitudinal base, which should be about 15 cm high.

In the next stage, the transverse bases are welded to the longitudinal ones. To add strength and reliability, it is recommended to use metal corners.

Lay bricks under the base; if necessary, a small groove can be made for the masonry.

Before erecting the frame, lay out the polycarbonate sheets, place the arches on top, and trace them with a marker. You can cut the material using a utility knife, leaving a margin of about 2 cm.

Once the solution has completely hardened, you should proceed to assemble the frame from the profile pipe. You need to weld the first arch to the longitudinal bases.

It is important to note that installing the first and last arch is a critical step, so it is recommended to use a plumb line.

Using crossbars, the remaining arches are welded sequentially. Specialists recommend starting to weld the arc to the upper crossbar. After the last arch is installed, you need to weld the end crossbars made of 20×20 section profile, as they do not carry a large load.

Polycarbonate is attached to the structure using special self-tapping screws with washers. Before covering, the protective film must be removed from the sheets. The first piece should protrude beyond the structure by approximately 15 cm.

After attaching the polycarbonate, you need to cut out openings for vents and doors. All joints must be treated with silicone.

The service life of such a DIY greenhouse is more than 10 years. Moreover, the structure does not require any maintenance.

When preparing a drawing of the greenhouse structure, it is important to consider that the pipe has standard sizes from 3 to 12 m. Therefore, you need to clarify this point with the seller. This will help avoid overpayments and allow you to work without waste.

Important! The cross-section of the profile pipe for the main parts should be 20×40, as well as 20×20 for the connecting elements.

The diagram must indicate the following data:

First of all, you need to decide on the distance between the vertical posts. Specialists recommend 1 m. In the case where the hotbed is intended to be covered with polyethylene film, the distance can be reduced to 0.6 m. This is necessary to reduce the load on the pipe. If it is necessary to increase the distance, then additional reinforcement is needed.

Creating an arch-shaped greenhouse requires a slightly different approach. After all, it is necessary to correctly bend the profile pipe at a specific angle. If the height of the hotbed is assumed to be 2 m, then you need to purchase a 12-meter pipe. It is recommended to make the distance between the arcs no more than one meter.

All arcs are fastened together, and in addition, profiles will need to be used on each side to secure the structure. In the diagram, specify additional struts on the front sides.

It should be understood that, if necessary, any parts can be made from the pipe, so it is possible to create a single-pitch, triangular, or spherical shape for the future greenhouse.

You probably realize that the structure will be quite heavy, so you need to prepare a base. The foundation is made at the discretion of the landowner. It is recommended to insert anchors directly into the cement solution, to which the frame is welded for reinforcement.

– For vertical posts, cut the profile pipe to the required size.

Step-by-step assembly of the greenhouse frame

1. Weld the vertical posts to the base, using a spirit level.
2. Take measurements and cut the parts for the vertical poles.
3. Connect and fix all the posts with transverse crossbars.
4. Make a door and install it in the intended place.

Some gardeners prefer to make the frame on the ground, and then fix it to the foundation. To avoid misalignment, such work must be done only on a flat surface.

To make an arch-shaped hotbed yourself from a profile pipe, you will need a pipe bender. If it is unavailable, to perform the bend, you must do the following:

In this case, specialists recommend starting the assembly from two sides. This allows you to achieve structural strength.

After assembling the frame, you need to attach the polycarbonate. But there are a few nuances here:

• The front side is the one on which the protective film is applied.
• The sheets must be fastened with self-tapping screws with a rubber head.
• The sheets are connected to each other with metal plates.
• After fixing the material, remove the protective film.

DIY construction of a greenhouse with a retractable roof

Now let's see how you can make a structure with an opening roof yourself. After all, not everyone has the funds to buy a finished structure, and others try to do everything with their own hands. For clarity, I will use videos and images in the article.

Before starting work, it is necessary to decide on the location of the future greenhouse with a retractable roof. Within a distance of 5 meters, there should be no structures or tall plantings so that shade does not fall on the plants in the greenhouse. It is also recommended to use a frame construction diagram.

But if you are not sure of your abilities, it is better to entrust the work to professionals who will build the structure according to your wishes based on the drawing.

Today, there are many types of structures with a retractable roof, so in this article, I will try to talk about the main points of manufacturing the structure.

Choosing materials for the frame and covering

What is the best material to build a greenhouse with a sliding or opening roof? The shape of the future roof depends on the design features, the sliding mechanism, and the covering material used. All these factors must be taken into account during the project development phase.

The choice of material for the frame depends on goals, preferences, and financial possibilities. Let us consider the features of the preferred materials:

Choosing materials for the greenhouse frame

• Metal. For a pitched roof, it is better to use angle steel or channel bars, while for an arched shape, it is recommended to use metal profiles or pipes. This material is very reliable, so the greenhouse will last for many years.
• Wood. People who decide to build the structure themselves most often use wood, as it is easier to work with. However, in this case, it will be quite difficult to make a sliding mechanism. Precise work is required for moving parts, so special technology and equipment will be needed to process the wood. It is better to buy a wooden structure from a manufacturer.
• Metal-plastic and plastic. These cheap and simple materials are most often used for the frame. This is because they are easy to process and assemble. Despite the low price of metal-plastic pipes, they allow for the construction of a reliable greenhouse with a service life that does not fall short of structures made from other materials.

A DIY greenhouse with a sliding roof made of metal-plastic and polycarbonate is a budget-friendly option for a land owner.

It is also necessary to decide on the covering material for a structure with an opening roof:

• Polycarbonate. Gardeners and farmers claim that a structure covered with this material is the best option. Thanks to its flexibility and light weight, polycarbonate is easy to process and can be shaped into an arch. On top of that, it lets in sunlight well and has excellent thermal insulation properties.
• Glass. This is a high-quality material that has good light transmission. However, glass elements are heavy, so it is necessary to prepare a foundation and a reliable frame for the greenhouse. Glass is recommended for use only by professionals who have experience working with it.

Choosing materials for the greenhouse roof

• Acrylic. In terms of its characteristics, it is similar to polycarbonate but is distinguished by high durability. Acrylic is easy to process and bend. When using it, there is no need to prepare a substantial foundation.
• Rolled materials. Film is rarely used for DIY construction of a greenhouse with a sliding roof, as it cannot withstand heavy loads and atmospheric exposure. Such a structure can last no more than two seasons.

Advantages of greenhouses with an opening roof

If you are still in doubt whether you need a structure with a sliding roof, it is recommended to learn about its advantages.

It is important to note that a greenhouse with an opening roof is only 5% more expensive than a regular structure.

In the winter period, snow falls onto the soil, which allows it to retain moisture and prevents it from drying out over a few months. Furthermore, the snow cover protects the beds from the death of essential microorganisms; otherwise, the soil becomes depleted in a short time. After all, it is more economical to maintain living soil than to replace it every year.

Thanks to the sliding roof, the structure is not subjected to heavy loads under the pressure of snow. Many people mistakenly believe that snow cover is not heavy. During the winter, a large layer can accumulate, the weight of which can reach several tons, especially if the snow is wet.

One should not trust advertising campaigns that claim a greenhouse is capable of withstanding snow loads.

Advantages and features of greenhouses with a sliding roof

In the summer, a greenhouse with a sliding roof is indispensable for gardeners. After all, one can slightly lift the roof to provide ventilation. Vents alone may not be enough, as the temperature inside the structure can reach 40 degrees, which negatively affects the plants.

An open door does not help to avoid overheating. However, the lifting elements of the roof allow for full ventilation of the greenhouse without creating drafts.

All plants need sunlight, but there is not enough of it in a closed greenhouse. Even a material such as light-transmitting polycarbonate absorbs many spectra. To avoid using artificial lighting, it is recommended to use a structure with a sliding roof.

Since childhood, everyone has known that warm air rises, which is why hot air collects under the greenhouse roof. One can get rid of the problem by opening the vents, but in this case, the plants might catch a cold.

One of the most significant advantages of a greenhouse with an opening roof is that one can build a lightweight structure without the use of supports. Therefore, it is possible to buy cheap profiles.

Despite the numerous advantages of such a greenhouse, not every gardener dares to erect such a structure on their plot. This is due to the fact that people are wary of innovations.

Before you start building a greenhouse with your own hands, you need to develop a project yourself or use ready-made solutions. However, I would still advise using the services of professionals who will prepare a blueprint for the future structure.

For private use, it is recommended to make a small structure out of metal profile. It is important to understand that the greenhouse should face south.

The following diagram shows a greenhouse structure made of polycarbonate. This blueprint allows for building a greenhouse of the following type. Another option for a structure diagram with a sliding roof:

Review of the "Kormilitsa – Umnitsa" greenhouse model

The Kormilitsa Umnitsa greenhouse: with an opening top (retractable roof).

Friends, I have seen many different greenhouses, but this hotbed interested me like no other. The main advantage of the Kormilitsa is that the roof opens completely. It is also called a retractable roof. This, in turn, is an additional plus because there is no snow load in winter, and when the warm season arrives, the roof can be closed with a special lever (it turns easily). In general, let's look at it in more detail... I am sure you will like it too!

For successful plant growing, an optimal microclimate, a sufficient amount of water, and good ventilation are required. Such conditions can be created using the greenhouse called "Kormilitsa – Umnitsa" with an opening roof.

In the summer, hot air can be released so that the seedlings do not burn. In many greenhouses, only vents and doors can be opened, but this does not allow for optimal ventilation, as it is known that warm air always rises. In addition, thanks to the opening roof, it is possible to provide full irrigation during rain.

After harvesting, with the onset of autumn, tree leaves fall into the greenhouse, which improve soil fertility. As a result, it is possible to grow organic vegetables.

During the cold period, the soil is covered with snow, so it does not freeze through. There is no need to regularly clear the snow cover from the roof so that it does not collapse under the weight.

A feature of the structure is the high strength of the frame. It is made of a square steel pipe, which is coated with a polymer. The walls of the structure are 1.5 mm thick. The company also produces models with 1.2 mm walls. In this regard, many people doubt that the greenhouse is strong. But such an opinion is erroneous, as the structure is very reliable.

The manufacturers note that if defects are found in the Kormilitsa – Umnitsa greenhouse, they will replace the structure.

The advantages of the structure include the following:

– The presence of 2 vents and 2 doors located at the ends.

– The roof opens completely thanks to a fixed winch.

– Polycarbonate covering provides natural lighting in the room.

To choose the optimal location for the greenhouse, you need to know some nuances:

– It is recommended to install the Kormilitsa – Umnitsa at a distance of 3 m from large trees and 5 m from any structures and buildings. This is necessary so that no shadow falls on the plants in the greenhouse.

– For better warming, it is recommended to install the structure facing south.

People who have purchased the Kormilitsa – Umnitsa greenhouse note that installing the structure is not difficult. The main thing is to follow the sequence. First of all, it is necessary to decide on the location. After that, start the assembly.

– Installation should begin with the ends, which consist of a doorway and arches that are fastened together with spacers.

– At the next stage, it is necessary to attach polycarbonate to the ends with roofing screws. Trim the excess with a regular utility knife.

– After that, you need to start installing the roof. Its structure consists of intermediate and end arches, as well as spacers. Before connecting, you should carefully study the instructions. For fastening, experts recommend using T-shaped connectors.

– Then the roof frames are covered with polycarbonate and fastened with roofing screws. After that, 8 special roller wheels are attached.

– After completing the steps, you can proceed to the installation of the greenhouse structure itself. Transverse spacers are installed on the ends. After assembling the frame, it must be secured to the foundation.

– Trellises are installed directly under the roof across the main beams. They are necessary for reinforcement and also for tying up tall plants.

– On one side, it is necessary to secure the winch used to open the roof.

– All latches, trims, and other fasteners are included in the kit, which are necessary for the reliable and safe opening of the roof.

It is important to note that to avoid malfunctions of the greenhouse, the central pipe must be installed strictly in the middle between the right and left edges.

Today we will examine a greenhouse made of plastic pipes, covered with polycarbonate. This material is the most affordable. Its special feature is that it allows sunlight to pass through, can last for a long time, and retains heat in the hotbed.

Some experts note that the material does not transmit more than 60% of light; however, in practice, it allows maintaining an optimal microclimate in the greenhouse even in the northern regions of the country.

Plastic pipes allow for the easy assembly of an arch-shaped structure. With a little skill, all work will take a minimum of time. Furthermore, this type of frame is one of the most economical.
