Load-bearing structure

The load-bearing structure consists of a set of main frames and two end wall structures, together with a wind bracing consisting of intersecting rods or portal frames.

The main frame is welded together from steel plate into I-shaped solid webs. The dimensions are in accordance with the drawings and strength calculations.

The total bearing construction is made of steel S355, grit blasted (grade Sa 2½) and covered with anti-corrosion layer, in a grey colour (i.e. RAL 7035). All joining connections in the construction use galvanised high quality steel bolts.

Roof construction

The roof is made of cold-formed, Z-shape steel purlins, to which profiled steel panels are attached. The steel purlins are galvanised on both sides with a zinc layer with a total thickness of 275 g/m² (Z-275).
The roof panels are galvanised on both sides, covered with a polyester layer in a white color.

Roof Insulation

The roof panels are covered with a damp insulation layer of polyethylene (PE) film with a thickness of 0,2 mm. Thermal insulation is mineral wool plates, 200 mm thick with thermal transmittance coefficient U = 0,18 W/m²K. The outer layer is made of 1,2 mm PVC membrane in a standard grey colour.

Skylights

Skylights construction is made of aluminium profiles with filling of multi-chamber polycarbonate plates (thickness 10-25 mm) with U coefficient ≤ 1,3 W/m2. The skylights are installed on a 50 cm high base (made of 2 mm thick galvanised metal sheet), insulated with mineral wool.

Wall Construction

The wall is made of cold-formed steel girts to which profiled steel wall panels are attached. The steel girts are galvanised on both sides with a zinc layer with a total thickness of 275 g/m² (Z-275). The wall panels are zinc-coated on both sides. The front side is coated with a polyester layer in a RAL colour. The rear side is coated with a light grey primer.
The wall panels are attached using self-tapping screws. The underside of the panelling is finished with a sill profile.
The wall panelling starts at level +0,35 m, from the concrete foundation beam.

Wall Insulation

The insulation consists of mineral wool insulation plates, with a total thickness of 200 mm and with a U coefficient ≤ 0,18 W/m²K. The plates are applied between wall panels.

Liner Panelling

For the internal system walls, profiled steel panels are applied to the inside of the wall girts. The panels are zinc-coated on both sides. The visible side is coated with a polyester layer in a RAL colour. The rear side is coated with a light grey primer. The wall panels are attached using self-tapping screws. The underside of the panelling is finished with a sill profile.
The wall panelling starts at the level of +0,35 m, from concrete ground beam.

Wall Openings

For the openings in the wall, like transport doors, walkthrough doors and windows, the necessary jambs made of steel profiles are applied.

Gutters and Downspouts

A system of roof gutters and downspouts are integral part of the building. Gutters are made of steel sheet, galvanised on both sides. The outside part is coated with a polyester layer in the facade colour or a colour chosen from RAL colour range.
