Steel bar grating, known for its high strength and robust structure, is manufactured from carbon steel, aluminum, or stainless steel. Depending on the production method, steel grating can be categorized into four types: welded bar grating, press-locked grating, swage-locked grating, and riveted grating. Based on surface design, it is available in both smooth and serrated options. With a wide range of styles and sizes, steel grating serves versatile applications in everyday life, including stair treads, walkways, platforms, flooring, trench covers, wheeled equipment, security screens, and heavy-duty constructions.
- Welded bar grating
Welded bar grating is also called metal open bar grating. Welded bar grating, also known as metal open bar grating, comes in two types: smooth and serrated. Smooth, or plain steel bar grating, is more popular, but serrated grating offers better skid resistance.
- Press Lock Grating
Made from low carbon steel, stainless steel, or aluminum, is created by bonding slotted bars under hydraulic pressure. It's strong, durable, and widely used in industrial and commercial applications like stair treads, platforms, walkways, and covers. Serrated surfaces enhance anti-slip properties.
- Swage Locked Grating
Swage locked grating, mainly made of aluminum or stainless steel bars, is formed by inserting cross bars into pre-punched bearing bars and locking them under hydraulic pressure. It comes in three bearing bar types: rectangular, T, and I bars, with I bars being lighter and more affordable.

Features of Steel Bar Grating:
1) High strength and light structure
2) Powerful anti-corrosion, durable and long working life
3) Beautiful appearance, bright surface
4) No dirt-rain-snow deposit, automatic cleaning, easy maintenance.
5) Good ventilation, day-lighting, heat-dispersing, resistant to sliding and explosion
6) Easy installation
- Surface Treatment
We provide four finishes for anti-corrosion treatment of carbon steel bar grating:
Black / Bare Steel: No finish, life is very short, but the price is the cheapest.
Painted Coat: The anti-rust effect is general and can be any color.
Electro-galvanized: A small amount of zinc coating, easy to cause slight corrosion in humid environment.
Hot-dip galvanized: The most commonly used method to provide the best anti-rust effect, strictly in accordance with ASTM A123 or GB/T 13912-2002.
