The significant feature of energy-saving corrugated cable trays is the groundbreaking use of concave convex corrugated structures in design. This unique corrugated structure greatly reduces the weight of the tray itself, improves the strength of the tray, and brings higher bearing capacity. Due to the reduced thickness of the bridge plate, the self weight can be reduced by 30% to 50%, which can save considerable material costs. The steel consumption of energy-saving corrugated bridge is more than 30% to 50% less than traditional ordinary bridge, and more than 15% less than energy-saving molded reinforced bottom bridge; Convection holes are installed on the side and bottom plates to create convection in the air inside the bridge, which is more conducive to heat dissipation; This unique structure also gives the bridge a true added value on the basis of a single use - a bridge with direct and indirect energy conservation.
