描述
400x400mm heavy-duty Thomas bolt truss is a professional aluminum box truss for stage rigging, concert lighting grids, LED screen frames, exhibition structures, outdoor events, stage backdrops, and large temporary support systems. The 400x400mm truss profile is suitable when a project needs stronger structure than smaller lighting truss while still keeping modular assembly and event-friendly handling.
According to the existing product reference, this heavy-duty Thomas bolt truss uses premium aluminum alloy with 50x3mm main tubes, 50x2mm vice tubes, and 25x2mm diagonal braces. The old content mentions a 440kg load reference and a maximum connected span reference of 17m. Final loading and span must always be confirmed according to truss length, support points, hanging equipment, wind condition, installation method, and the complete structure drawing.
