Load-bearing structureThe 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 constructionThe 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 InsulationThe 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.
SkylightsSkylights 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 ConstructionThe 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 InsulationThe 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 PanellingFor 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.
