描述
400x400mm heavy-duty square bolt truss is a strong aluminum box truss for stage roofs, lighting beams, concert structures, exhibition frames, LED screen support, event backdrops, and temporary roof truss systems. The 400x400mm truss profile is suitable for projects that need higher structural strength than smaller lighting truss while keeping a modular bolted connection for project assembly.
According to the existing product content, this heavy-duty aluminum bolt truss uses side tubes arranged like ladder reinforcement to strengthen vertical beam performance in box truss systems and roof truss structures. The old content mentions a CPL reference of 450kg, a UDL reference of 55kg at 16m span, and TUV certificate reference. Final load capacity and span must always be confirmed according to the complete truss design, support points, hanging equipment, wind condition, connection method, and site requirements.
