What Is Steel Grating?
Steel grating, also known as steel grid or bar grating, is a versatile and robust flooring solution designed for industrial, commercial, and architectural applications. Made from high-quality carbon or stainless steel, our steel grating features a lightweight yet durable design that ensures excellent load-bearing capacity and long-lasting performance.
Steel Grating Types
- Plain Type: One of the most widely used gratings, available for flooring, sidewalk, drainage pit cover, stair tread, etc.
- Serrated Type: Better non-skid property and safety compared with plain grating.
- I Bar Type: Lighter, more economical, and practical compared with plain grating.
