Arcs for the greenhouse: varieties, assembly method

With the increasing popularity of the installation in summer cottages andhomestead plots of easy-assembled greenhouses in the market increased demand for arcs for greenhouse. They are responsible for their durability and sustainability. This is a kind of "skeleton" of a greenhouse.
Basically, for the production of arcs,plastic (or fiberglass), polypropylene, and also metal. The price, weight, maximum sizes depend on the material from which the greenhouse is made.

Another criterion by which arcs are distinguishedfor the greenhouse, was the way of assembly and installation of the structure. There are two large groups: prefabricated greenhouses and welded ones. The first can be collected and disassembled several times. For this, plug-in connections without fasteners or with the use of metal products (bolts, nuts, screws, etc.) can be used. Disadvantage of this type of greenhouses can be considered their small size and relatively low strength. Welded greenhouses are much stronger, but after the assembly they, as a rule, are not subject to dismantling. Such designs are ideal for the infield and can be used all year round.

Let's consider each variant in more details. The case where the arcs for the greenhouse are made of plastic, suitable for growing small plants, for example cucumbers or peppers. Such structures, as a rule, are covered with a film and used only in the warm season. To make such a hotbed at home is not difficult. As a frame, polypropylene pipes are excellent, which can be found in any sanitary ware shop. For welding, a special "iron" is used. Connections can be made and dismountable, but this will affect the strength of the entire structure.

Arcs of metal for a greenhouse can also beboth welded and prefabricated. However, unlike plastic ones, the second designs have become more widespread, as they are faster in assembly and do not require welding equipment and special skills. In the kit for these greenhouses is detailed instruction, which greatly simplifies the work. As a covering material, polycarbonate or polyethylene film is mainly used. The metal frame is much stronger than the plastic, so it allows you to operate the greenhouse year round, even withstanding the snow cover in winter. Another undeniable advantage of metal arcs is the size of the greenhouses. They can be made in human growth and higher, and also cover large areas, depending on the design.

As for self-manufacturingmetal arcs, the situation here is more complicated than in the case of plastic. The material is much more expensive, and besides the master must have special skills for doing such work, and also use welding and other construction equipment. In addition, the arc for a greenhouse to buy today will not be very difficult. The market is full of offers for the sale and manufacture of greenhouses on individual sizes. Ultimately, considering all the costs, it is more profitable to purchase a finished structure with a metal frame, rather than trying to do something similar on its own.
