Steel grating, also known as bar grating or metal grating, is an open grid assembly of metal bars designed to support heavy loads with minimal weight. It consists of bearing bars, running in one direction, spaced by rigid cross bars or bent connecting bars. Commonly made from ASTM A-1011 mild carbon steel or stainless steel, it’s ideal for platforms, walkways, and stair treads.

Steel grating is manufactured based on customer-provided drawings to ensure precision. Our company employs dedicated design and technical departments with extensive experience to meet specific client requirements. The process involves cutting, welding, or locking bars, followed by surface treatments like galvanizing for enhanced durability.

Steel grating comes in three primary types:

Type “W” Welded Bar Grating: Bearing bars are welded to cross bars, offering a sturdy structure for high-strength applications.

Type “SL” Swage Locked Grating: Cross bars are mechanically locked into bearing bars, providing a smooth, aesthetic finish.

Type “DT” Dovetail Pressure Locked Grating: Bars are interlocked under pressure for a secure, seamless fit.

Pressure-locked grating has no welds, offering better corrosion resistance and a more aesthetic appearance, ideal for decorative or corrosive environments.

Welded grating is cost-effective, highly durable, and suited for high-load applications like warehouses.

Steel grating is typically made from:

Carbon steel (ASTM A-1011): Ideal for high-traffic areas.

Stainless steel: Suited for high-temperature or corrosive environments.

Aluminum: Lightweight and corrosion-resistant, perfect for applications needing a high strength-to-weight ratio.

Surface treatments like galvanizing enhance longevity.

Yes, we offer aluminum grating (with anti-slip serrations), stainless steel, galvanized steel, and custom-shaped gratings to meet specific project needs.

Steel grating is widely used for:

Platforms

Walkways

Stair treads

Catwalks

Ramps

Mezzanines

Industrial flooring

Petrochemical projects

Sewage treatment plants

Bridge decoration

Its strength and durability make it a top choice for industrial and commercial settings.

Welded steel grating is recommended for warehouses due to its high strength and durability, making it ideal for heavy-load environments.
