Classification of Steel Grating
By Manufacturing Process
Press-Welded Steel Grating
Most commonly used. Machine-welded with high structural strength, suitable for standard industrial applications.
Hand-Welded Steel Grating
Ideal for custom shapes and non-standard sizes, offering flexibility for special project requirements.
Insertion (Swage-Locked) Steel Grating
Also known as interlocking grating. Provides a clean, smooth appearance and is commonly used in high-end commercial or architectural applications.
- By Application Scenario
Platform Steel Grating
Heavy-duty design, ideal for factory workshops, structural platforms, and industrial walkways.
Drainage Trench Covers
Available with frame or lockable type for easy opening and anti-theft protection.
Stair Treads
Designed with side plates or bolt holes for safe and easy installation on staircases.
- By Material
Mild Carbon Steel Grating
Low cost with high load-bearing capacity, suitable for general industrial use.
Stainless Steel Grating (304 / 316L)
Excellent corrosion resistance, ideal for harsh environments such as chemical plants, coastal areas, and food processing facilities.
Composite Steel Grating
Features a non-slip top plate that combines sealing performance with high load capacity.
- By Surface Treatment
Hot-dip galvanized, cold galvanized, electro-galvanized, powder coated, rust-proof oil dipped, plastic coated, or untreated.
Surface treatment options ensure durability and corrosion resistance according to your working environment.
- By Surface Profile
Plain Surface
Smooth and standard, suitable for most general applications.
Serrated Surface
Manufactured with serrated bearing bars to deliver superior anti-slip safety in oily, wet, or greasy conditions.
