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 M12x180/055 (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 M12x180/055 (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
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 hole saw 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.
