Steel structures of the hall are manufactured in full conformity with the standard ČSN EN ISO 1090-2+A1:2012, in the EXC2 design class in conformity with the standard ČSN EN ISO 3834-2:2006 (certificates can be found here: Technical parameters – Building permit).
Light steel structures consist of girder frames, interconnected at the given module distance. The base of the frames is formed by flanges made of hollow sections of the pertinent dimension, trussed with steel tubes.
The individual frames are joined into a unit creating the load bearing structure of the object, and is anchored to the subsoil by means of the foundation profile. These structures are suitable for lining by means of a tarpaulin, trapezoidal sheet or by mutual combinations or other materials.
Structure fully consisting of a girder frame shaped as an inverse letter U. It is therefore a vertical wall with a round transition.
The most common and economical type of structure.
Structure fully consisting of a girder frame with a saddle roof;that is, the classic shape known, for instance, from residential houses.
Structure based on the UT type, in which, however, the vertical girder parts of the frame have been replaced with rolled steel sections that penetrate less into the internal hall space. Thus the structure offers a larger usable space in comparison with the UT type with the same ground plan dimensions.
Structure based on the AT type in which, however, the vertical girder parts of the frame have been replaced with rolled steel sections that penetrate less into the internal hall space. Thus the structure offers a larger usable space in comparison with the AT type with the same ground plan dimensions.
Heavy and special structure
With the heavy structure, the load-bearing skeleton is in most cases made from solid rolled steel sections, or by their combination with rectangular sections.
These halls are particularly suitable to be lined with sandwich panels or trapezoidal sheets.
Basic protection against the action of climatic conditions on the steel structure. Coating is executed by means of a synthetic system particularly adapted to the conditions of steel structures manufactured by the POLAK CZ company, in a thickness determined for the specific hall, depending on the equipment, to corrosion protection class C1 – C5 in conformity with ČSN EN ISO 1090-2+A1:2012 in compliance with EN ISO 12944 and EN ISO 14713. Therefore, the coating thickness is determined according to the specific site of the hall construction and method of use. The basic colour shade RAL 7012 of the structure can be changed upon request.
Increased protection of the steel structure more stressed by weather conditions or internal climatic conditions resulting from the object use, such as the material stored. Hot-dip galvanizing on the steel structure is executed in conformity with EN ISO 1461:1999.
In special cases, when increased requirements are placed on fire resistance of the load-bearing structure, a fire-resistant coating is executed so that the structure can conform to these requirements. Increased requirements for the fire resistance of the structure result from the Fire safety design of the construction, which is generally based on the ČSN 730810:2009 standard and the standards of ČSN 730202 Fire safety of buildings – Non-production objects and ČSN 730202 Fire safety of buildings – Production objects.
