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:  An overhead door opens by means of rails that hang horizontally in the space, so that the guide rails can interfere with each other with certain door position combinations.
Metal sheeting

*Colors can slightly differ from reality.

Skylights
16 insulated polycarbonate skylight panels. Only available for thickness 40 mm. Dimensions light surface 432 x 110 cm per panel.
Steel structure
Galvanized steel S390, c-profile, thickness 2,0 / 2,5 mm, truss distance 3,3 meter.
Gutter system (optional)

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 (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 (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 1,200 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.
