The secret to the strength (and speed of construction) of our steel frames is the patent pending LOCX system. This allows any size steel box section or steel I-beam to be quickly and securely attached to create any size frame. Perfect not just for lodges, garages, garden offices and mezzanine floors but also for permanent and temporary supports or access platforms inside and out. Eliminates the expensive and time consuming need to weld with the ease to dismantle, adjust, extend and relocate.
