Prefabricated metal structures first appeared in the construction industry right after World War Two in the USA. They became immensely popular almost immediately thanks to the speed with which these structures could be assembled and, if need be, disassembled.

The structure of metallic frames

The base for all prefabricated buildings is a metallic frame, consisting of vertical struts and horizontal bearers connected with bolts into transverse frames, which, in turn, are attached to the foundation at a previously determined distance from one another. Transverse frames serve as a basis for an entire system of carrier cables that provide the calculated strength of the structure. Installation of beams and rafters with framings for windows and doors is the next step.
Any material may be used as the lining coating: reinforced concrete, bricks, specialized panels are all perfect choices for this task. It is even possible to combine several types of coating.

Distinctive traits

Several features can be singled out of the many defining traits of metalwork structures. They are:

High readiness level of material;

All elements of a given structure are manufactured by the same factory, where they are rigorously tested to determine their strength characteristics.
Dimensioning specifications;

Due to the structure being divided into a certain number of constituent elements, it can be transported to any construction site with ease, using traditional means of transportation.

Utility, reliability and high quality;

A check fit-up is performed at the factory, which allows us to exclude the possibility of any complications during the assembly process on-site. In case of any mismatches, the constituent elements are fitted to the required specifications.

Area of application

The area of application for structures made of metal is very broad. It includes construction of industrial structures of various purpose, warehouses, sports complexes, trade centers, malls and other specialized buildings.

There is, however, a list of structures for which the use of metallic frames would not be advised, such as:
- Nuclear reactors;
- Bank vaults;
- Other structures where special attention to isolating properties is required;

As to the advantages of the material, the biggest one of them is cost-cutting.

The entire construction process may turn out to be up to 40% cheaper for the client. The savings are especially noteworthy for the underground stage, where they can reach 50%.

It is worth noticing that the low cost, ease of assembly and utility of the structure are complimented by the fact that a completed structure may be disassembled without significant expense.
