4000×1800mm Beam Single Piece

1800×4000×100mm extended super heavy-duty Beam Single Piece truss, fully welded integrally with high-strength Q355B structural steel. Main tubes and vice tubes adopt ultra-thick 100×100×8mm square pipes, double groups of X cross braces use 80×80×6mm pipes, with a net weight of 448kg per piece. The dual-section cross brace structure greatly improves bending and torsion resistance for the 4m ultra-long span. As the extended core horizontal load-bearing component for ultra-heavy load truss systems, one piece achieves 4m large-span construction, reducing splicing joints and greatly boosting overall frame stability. It is widely applied for ten-thousand-person outdoor music festivals, large commercial touring shows, stadium large lighting & sound rigging and heavy-load construction for mega exhibitions. As professional truss manufacturers, we provide truss wholesale bulk order service. It can be matched with matching heavy column single pieces and 15T base to assemble complete giant heavy-load truss systems. Featuring thick pipe walls and extreme structural rigidity, it resists deformation under long-term heavy loads, with modular lock splicing for easy assembly, the ideal beam component for indoor & outdoor high-load long-span overhead rigging projects.
