Light steel structures
The light steel structures are made of girder frames interconnected at the given module distance. The base of the frames is 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, being anchored to the subsoil by means of the foundation profile. These structures are suitable for lining by means of a canvas, trapezoidal sheet or by mutual combinations of other materials.
UT structure
Structure fully consisting of a girder frame shaped like an inverted U. It is therefore a vertical wall with round transition. The most common and economical structure type.
AT structure
Structure fully consisting of a girder frame with a saddle roof; that is, the classic shape known, for instance, from residential houses.
UTS structure
Structure based on the UT type, in which, however, the vertical girder parts of the frame have been replaced with rolled steel sections that protrude less into the internal hall space.
ATS structure
Structure based on the AT type, in which, however, the vertical girder parts of the frame have been replaced with rolled steel sections that protrude less into the internal hall space.
Heavy steel structures
With the heavy structure, the load-bearing skeleton is in most cases executed from solid rolled steel sections, or by combining them with rectangular sections. These halls are particularly suitable for lining with sandwich panels or trapezoidal sheets.
Coating system
The coating constitutes the basic protection against the action of climatic conditions on the steel structure. It 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 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.
Zinc coating
Increased protection of the steel structure more stressed by weather conditions or internal climatic conditions resulting from its use, such as the material stored. Hot-dip galvanizing of the steel structure is executed in conformity with EN ISO 1461:1999.
Fire-resistant coating
In special cases, when stricter requirements are placed on fire resistance of the load-bearing structure, a fire-resistant coating is applied so that the structure can conform.
