Infrastructure Steel Construction Product Introduction For steel structure building construction, infrastructure steel construction steel structure roof is vital. Steel structure roof insulation usually adopts three methods; Indoor spraying flame retardant polyurethane; Indoor adhesion of silicate rock wool; Indoor adhesive polystyrene foam. It has been widely used for various steel structure buildings like steel structure workshop. Product Detail The technical performance of steel structure as follows: (1) The yield strength of the substrate is 280Mpa or 350Mpa. (2) The amount of galvanizing is ≥180g/m2. ⑶ coating thickness ≥ 20um. ⑷ Salt spray resistance ≥ 500h.
