The basic building frame is formed from heavy gauge mild steel sections, each fully welded to form a rigid framework into which the wall panels, doors and windows are fitted.
The base rail is a 3mm thick ‘z’ section, which is fully welded into the corner posts. The floor joists are welded inside the base rail at 406mm centres on all products up to 10’ in width to form the floor frame. On 12’ wide units the floor joists are fixed at 203mm centres. The corner posts support the 50mm x 10mm flat bar which runs around the top of the wall panels to form a rigid section onto which the roof panels are fitted. Reinforcing sections are welded inside the flat bar both across the unit width and also longitudinally to complete the framework. This section sits underneath the roof panels to provide additional support to help prevent roof damage and improve water drainage.
The frame is completed by 6mm top plates and 10mm base plates which are welded to each of the four corner posts. These are fitted with a basic hole and pin to provide a positive initial location when the units are stacked and matching connection slots to ensure the required long term stability.
Four high level lifting points are fitted along the side sections of the roof and four low level lifting points are fitted along the side sections of the floor to allow the simple lifting of the unit by a suitable crane. The floor is fitted with continuous fork tunnels across the width of the unit to allow lifting and movement of the unit by a suitable fork truck. The four low level lifting eyes also act as lashing points to allow the product to be easily secured to the delivery vehicle whilst in transit.
