Drainage Steel Grating Product Introduction

Our drainage steel grating is professionally welded by bearing flat bars and cross bars. Designed for high-efficiency drainage, this grating is a durable solution for trench, sewer and floor drain projects. We offer hot-dip galvanized carbon steel and stainless steel grades, with serrated anti-slip options for wet, slippery working areas. It delivers stable load performance and outstanding corrosion resistance for municipal, industrial and water treatment applications.

Frequently Asked Questions

Q: What material should I choose?

A: Hot-dip galvanized Q235 is popular for regular outdoor projects to control cost. 304 / 316 stainless steel is recommended for sewage, chemical and food environments with high corrosion risk.

Q: Is anti-slip grating available?

A: Yes. Serrated flat bars are available to improve friction and prevent slipping on wet surfaces.

Q: Do you accept custom sizes?

A: Absolutely. We can fabricate as per your drawings, trench width and load standard.

Q: How to confirm the load specification?

A: Load capacity depends on flat bar height, thickness and spacing. Kindly advise if it is for pedestrian, light vehicle or heavy truck use, we will provide proper suggestions.

Q: Can I get samples?

A: Samples are available for quality inspection. The buyer will cover the shipping cost.
