BW Side Rail Restraining Systems
- BW ‘Restraint’ or ‘Supporting’ ancillaries are incorporated to deter loading deformation of the side rails and assist in strengthening the overall structure when loaded with the side sheeting.
- All loading conditions are specifically calculated, only use BW products illustrated to ensure correct stability under wind pressure and suction loads.
