Roll-up door (included)
305 x 275 cm (H x W), clearance 291 cm, color RAL 9002 (grey white), including latch for padlock (padlock not included), 0,45 mm steel, non-insulated, manual operation, polyester coating, model Janus 650.
Overhead door
305 x 275 cm (H x W), clearance 301 cm, color RAL 9002 (grey white), including latch for padlock (padlock not included). Cannot be opened from outside.
The door consists of sandwich panels with a thickness of 4 cm. The outside has a micro-profile, the inside is horizontally profiled. Running rails of galvanized steel. Galvanized door fittings. Steel cables with six-fold safety. Spring package is suitable for a minimum of 30,000 door movements. EPDM seals around and between the panels.
Electric opener overhead door (optional)
220V drive unit with LED lighting + 2x remote control + complete installation set
Man door (included)
Opening dimensions 209 x 93 cm, color RAL 9002 (grey white), including door handle with backplate and integrated lock (1 key, prepared for 17mm cilinder). All-steel door with rock wool filling, sheet thickness 0.9 mm, with four-sided EPDM sealing rubbers. Direction of rotation can be executed both left and right.
Door positions
The storage building comes standard with an overhead door and a man door in the front wall. Other door positions are possible, taking into account:
1) Wind bracing may be moved, but not to the first or last section
2) Man doors can be placed in any section except those with wind bracing
3) With a roll-up door in the front wall, an extra roll-up door can be installed from H1213
4) An overhead door opens on rails that hang horizontally in the room. In certain door position combinations, the guide rails may obstruct each other; as such, with an overhead door in the front wall, an additional overhead door can only be installed from H1113. If there is an overhead door in the rear wall then only from H1217.
5) A roll-up door rolls up like a roller shutter above the door opening, taking up less space and allowing more options for installation
Metal sheeting
Trapezoidal profile sheet S280GD, sheet thickness 0.5 mm (NEN-EN 10169). Roofing sheets coated with a layer of DripStop® condensation control.

MagiZinc® + Colorcoat® Polyester 25μm, maintenance free. Innerside wall panels RAL 7035 (light grey).

For the outside you can choose between the colors RAL 3009, 6020, 7016, 7040, 8004, 8012, 9005 and 9010*

*Colors can slightly differ from reality.

Skylights
20 transparant high impact polycarbonate panels. Dimensions light surface 296 x 90 cm (H x W) per panel.
Steel structure
Galvanized steel S390, c-profile, thickness 2,0 / 2,5 mm, truss distance 3,3 meter.
Gutter system (optional)
Set of steel roof gutters and downspouts in the colors RAL 9022 (pearl light grey) or RAL 7016 (anthracite), width of gutter 125 mm, diameter of downspout 80 mm.
Anchoring
For a permanently installed building
Option 1. Concrete foundation
Concrete (strip) foundation to be prepared according to Kroftman drawings (included). Base rail of building is bolted with concrete anchors M12x180/020-035 (not included). The concrete surface needs to be perfectly straight to obtain a watertight joint of the walls.

Option 2. Prefab concrete slab elements
Construct a sandbed to the frost line containing a spacious floor of prefab concrete panels (concrete slab elements) of 16 cm minimum. The soil profiles of the storage building need to be fastened with concrete anchors M12x180/020-035 (not included).

This option is economical and fast. The surface must be flat, with a permitted slope of max. 1 cm/m1 in one direction only. A curved surface is not allowed. A slope in the installation surface must be filled out during installation, resulting in additional work.

For a temporarily or semi-permanently installed building
Option 3. Earth anchors (not included)*
Earth anchors 1,100 x 25 mm for anchoring on pavement, asphalt or hard gravel. The installation surface must be straight with a maximum slope of 1cm/m1 limited to one direction. A curved surface is not allowed. A slope in the installation surface must be filled out during installation, resulting in additional work. Base rail holes of ∅30 mm are to be drilled on-site. (adequate holes aw is included).

Installation of your steel building with earth anchors saves time and money and is the perfect solution when only temporily constructions are allowed or needed.

* A storage building with industrial doors in a side wall cannot be assembled with earth anchors. This combination would lead to subsidence because of increased pressure on the surface on both sides of these industrial doors. This can be solved by applying a concrete footing on either side of the industrial door. This problem does not occur with industrial doors in the front or rear. (H609 and longer)
