Our annual export value exceeds US$2.5 million, serving markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. We are proud to present our Heavy Duty Steel Trench Drain Cover, specifically engineered for demanding drainage applications where strength, durability, and safety are non-negotiable.
This drain cover is constructed from premium Q235 steel with a thickness of 3mm and finished with a hot-dip galvanized coating that provides exceptional corrosion resistance.

Frequently Asked Questions (FAQ)
-
Q: What is the load capacity of this drain cover?
A: It is rated Load Class B125, meaning it can withstand a vertical load of 125 kN (approximately 12.5 tons). This makes it suitable for light vehicle traffic such as cars, SUVs, and small trucks. For heavy truck or industrial use, we recommend higher load classes like C250 or D400 (available upon request). -
