Galvanized Expanded Metal Trench Cover, Drainage Grating for Industrial Floors

Product Description

Anping Chuangyi Hardware Products Co., Ltd., based in Anping – the global wire mesh hub – supplies galvanized expanded metal trench covers as drainage grating for industrial floors. Unlike solid cast iron covers, our diamond openings allow rapid water drainage while trapping large debris to prevent clogging. One-piece expanded construction – no welds – delivers high load capacity for forklifts, trucks, and foot traffic. Hot dipped galvanized coating provides uniform, dense zinc layer for 10+ years of corrosion resistance. Edges can be framed or folded to resist warping and allow easy lifting for cleaning. Standard sizes fit most trenches; custom length, width, and load ratings available. Factory direct with load test reports. Ideal for factories, warehouses, distribution centers, and parking lots.
