Square timber constructions are shipping packagings adapted to the load.
They are used where a transport slide or a fixation of the goods on transport floors are not possible. They are mainly used as the static support and only these special constructions make in some cases the transport possible. However, a prerequisite for a safe shipping unit is the insensibility of the goods against corrosion damages.
If this is provided, then square timber constructions will be designed by adhering to safety relevant aspects and they will be installed on-site.
