About this product
Product information from the supplier.
Our industrial-grade Steel Grating and Bar Grating solutions are engineered for maximum durability and safety, serving as the ideal choice for trench covers, foot plates, and heavy-duty walkways. Manufactured from premium carbon steel and stainless steel, these gratings are designed to withstand extreme industrial environments while providing critical functionality such as ventilation, lighting transmission, and heat dissipation.
To ensure long-term resistance against oxidation and corrosion, our steel gratings undergo rigorous surface treatments, including hot-dip galvanizing. With a versatility that spans across petrochemical plants, power stations, municipal engineering, and shipbuilding, our gratings combine structural integrity with a non-slip surface to ensure operational safety in the most demanding settings.

Frequently Asked Questions
For highly corrosive environments, we recommend Stainless Steel (316 or 316L) or Aluminum gratings, as they provide superior resistance to chemical oxidation compared to carbon steel.
Plain bars are smooth and suitable for dry areas. Serrated bars have a tooth-like profile that provides significantly higher traction, making them essential for oily, wet, or icy walkways.
Yes, we offer full customization. You can specify the bearing bar size, pitch, cross bar spacing, and overall dimensions to fit your exact project requirements.
Our products are manufactured according to global standards, including ANSI/NAAMM (USA), BS4592 (UK), AS1657 (Australia), and JJS (Japan), ensuring quality and safety worldwide.
Hot-dip galvanizing creates a thick, durable zinc coating that bonds to the steel, providing an exceptional barrier against rust and oxidation, drastically extending the product's lifespan.
They are widely used in petrochemical plants, power stations, water treatment facilities, port terminals, shipbuilding, municipal engineering, and architectural decoration.
