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

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 of 45 cm minimum (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.

For 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 1% limited to one direction. Base rail holes of ∅30 mm are to be drilled on-site (adequate holesaw is included).

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