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 S235JRG2 (St3S) or S355JR (18G2A) or steel grit blasted SA 2.5 and covered with anti-corrosion layer, in the RAL 7035 colour. All coupling connections in the construction use galvanised high quality steel bolts.
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; total thickness of zinc layer 275g/m² (Z-275). The wall panels are zinc-coated on both sides. The front side is Polyester coated. The colour can be chosen from our standard colour range. The inside is coated with a light grey primer. The wall panels are attached using self-tapping screws furnished with neoprene washers to avoid leakage. The underside of the panelling is finished with a sill profile. The wall panelling starts at the level of +35 cm.
The insulation consist of glass fibre insulation blankets of the usual thickness of 100 mm and with a U=0.44 W/m²K coefficient. The blankets are applied between the girts and the wall panels and are built up as follows (beginning from the visible side): a white vinyl layer with a linen pattern emboss (type CF 305), a fibre glass scrim reinforcement 5 x 5 mm and an aluminium foil as a good moisture vapour barrier. To ensure an unbroken damp proof layer the seams are sealed using a specially folded and stapled seam.
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 Polyester coated, white for example. The rear side is primer coated in a light grey colour.
The roof is made of cold-formed steel purlins, to which profiled steel panels are attached. The steel purlins are galvanised on both sides with the zinc layer total thickness of 275g/m2 (Z-275). The roof panels are zinc / aluminium alloy coated on both sides. They are attached using self-tapping screws furnished with neoprene washers to avoid leakage. A self-adhesive, non-drying sealing tape is applied in all the over-lapping areas both lengthways and crossways. Filling strips of polyethylene foam are used under the roof panels around the gutter in order to obtain complete sealing..
The insulation consists of glass fibre insulation blankets with a usual thickness of 140 mm and a U=0.30 W/m²K coefficient. The blankets are applied between the roof purlins and the roof panels and are built up as follows: a white vinyl layer with a linen pattern emboss, type CF 305 (visible side) a fibre glass scrim reinforcement 5 x 5 mm and an aluminium foil as a good moisture vapour barrier. To obtain an unbroken damp proof layer the seams are sealed using a specially folded and stapled seam. Iso-blocks (19 x 60 x 1000 mm) are placed between the roof insulation blankets and the profiled roof panels at the girt locations.
For the openings in the wall, like transport doors, walkthrough doors and windows, the necessary jambs are made out of galvanised "C" profiles.
In the roof construction translucent double walled panels are placed. The top sheet is a profiled polyester, opal coloured, sheet, with its shape matching the roof cladding. The second sheet is a clear polycarbonate channel sheet. Both sheets are airtight glued together.
A system of roof gutters and downspouts forms an integral part of the building. Gutters are made of pressed sheet galvanised on both sides. The outside part is coated with Polyester in the facade colour or a colour chosen from our standard colour range, the inside with a light grey primer. Downspouts are made of round PVC pieces in a RAL colour chosen from our standard colour range.

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 S235JRG2 (St3S) or S355JR (18G2A) or steel grit blasted SA 2.5 and covered with anti-corrosion layer, in the RAL 7035 colour. All coupling connections in the construction use galvanised high quality steel bolts.

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; total thickness of zinc layer 275g/m² (Z-275). The wall panels are zinc-coated on both sides. The front side is Polyester coated. The colour can be chosen from our standard colour range. The inside is coated with a light grey primer. The wall panels are attached using self-tapping screws furnished with neoprene washers to avoid leakage. The underside of the panelling is finished with a sill profile. The wall panelling starts at the level of +35 cm.

Wall Insulation

The insulation consist of glass fibre insulation blankets of the usual thickness of 100 mm and with a U=0.44 W/m²K coefficient. The blankets are applied between the girts and the wall panels and are built up as follows (beginning from the visible side): a white vinyl layer with a linen pattern emboss (type CF 305), a fibre glass scrim reinforcement 5 x 5 mm and an aluminium foil as a good moisture vapour barrier. To ensure an unbroken damp proof layer the seams are sealed using a specially folded and stapled seam.

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 Polyester coated, white for example. The rear side is primer coated in a light grey colour.

Roof construction

The roof is made of cold-formed steel purlins, to which profiled steel panels are attached. The steel purlins are galvanised on both sides with the zinc layer total thickness of 275g/m² (Z-275). The roof panels are zinc / aluminium alloy coated on both sides. They are attached using self-tapping screws furnished with neoprene washers to avoid leakage. A self-adhesive, non-drying sealing tape is applied in all the over-lapping areas both lengthways and crossways. Filling strips of polyethylene foam are used under the roof panels around the gutter in order to obtain complete sealing.

Roof Insulation

The insulation consists of glass fibre insulation blankets with a usual thickness of 140 mm and a U=0.30 W/m²K coefficient. The blankets are applied between the roof purlins and the roof panels and are built up as follows: a white vinyl layer with a linen pattern emboss, type CF 305 (visible side) a fibre glass scrim reinforcement 5 x 5 mm and an aluminium foil as a good moisture vapour barrier.

Wall Openings

Skylights

In the roof construction translucent double walled panels are placed. The top sheet is a profiled polyester, opal coloured, sheet, with its shape matching the roof cladding. The second sheet is a clear polycarbonate channel sheet. Both sheets are airtight glued together.

Gutters and Downspouts

A system of roof gutters and downspouts forms an integral part of the building. Gutters are made of pressed sheet galvanised on both sides. The outside part is coated with Polyester in the facade colour or a colour chosen from our standard colour range, the inside with a light grey primer. Downspouts are made of round PVC pieces in a RAL colour chosen from our standard colour range.
