Welded Stainless Steel Bar Grating

Steel Grating is a specialized water treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid, and can be widely used in urban sewage treatment. It can also be used as a front-end screening equipment in wastewater treatment processes in industries such as textiles, food processing, papermaking, leather, etc. It is one of the most advanced solid-liquid screening equipment.

Types of Stainless Steel Bar Grating

Type "WS" Welded Stainless Steel Grating

Our strongest and most economical stainless product, type WS gratings are made by forge welding rectangular bearing bars and drawn cross bars. The welding process provides a positive fused intersection providing years of service under the most demanding conditions.

Type WS stainless gratings are available in 19 space (1-3/16"), 15 space (15/16"), and 11 space (11/16") bearing bar centers. Standard cross bar spacing is 4" on center with optional 2" spacing available.

Type "SLS" Swage Locked Stainless Steel Grating

Hollow tube cross bars are hydraulically swaged into pre-punched holes in the bearing bars to make type SLS swage locked stainless grating. This type of construction provides a secure bearing bar/cross bar intersection and products are available with bearing bar spacings ranging from 19/16" (1-3/16") to 7/16" on center.

The swaged cross bars sit slightly below the top surface of the grating making this product very popular for "close mesh", ADA conforming applications. 11 space and 7 space are ideal for vault covers or entrance mats located in the public way.

Type "DTS" Dovetail Pressure Locked Stainless Steel Grating

Manufactured with deep rectangular cross bars, type DTS dovetail stainless grating is commonly preferred for architectural applications. Sunscreens, grilles, and infill panels are just some applications where this distinct egg-crate configuration is the ideal accent.

Type DTS gratings are available with bearing bar spacings ranging from 19/16" to 7/16" on center. For architectural applications where increased bearing bar spacing is desired please contact our sales department.

FAQ

1. What is stainless steel grating?
Stainless steel grating is a type of open-grid metal platform made from corrosion-resistant stainless steel bars, providing strength, durability, and slip resistance for industrial, commercial, and architectural applications.

2. What are the common applications of stainless steel grating?
Stainless steel grating is widely used in chemical plants, food processing facilities, marine environments, wastewater treatment plants, walkways, platforms, and architectural projects where corrosion resistance and safety are critical.

3. How does stainless steel grating resist corrosion?
It resists corrosion due to the high chromium content in stainless steel, which forms a protective oxide layer on the surface, preventing rust and deterioration even in harsh environments.

4. Can stainless steel grating support heavy loads?
Yes, stainless steel grating is engineered to carry substantial weight. The load-bearing capacity depends on the bar size, spacing, and design, making it suitable for industrial platforms, bridges, and heavy machinery walkways.

5. What are the different types of stainless steel grating?
The main types include welded bar grating, press-locked grating, and serrated grating. Serrated grating provides extra slip resistance, while welded and press-locked gratings offer high strength and uniform load distribution.

6. How do I maintain stainless steel grating?
Maintenance is simple: regular cleaning with mild detergents or water removes dirt and debris. Avoid harsh chemicals to preserve the protective oxide layer and extend the grating's lifespan in outdoor or industrial environments.
