Product Overview

Our welded stainless steel bar grating is a high-strength, corrosion-resistant flooring and drainage solution designed for demanding industrial, commercial, and architectural applications. Manufactured by permanently welding bearing bars and cross bars together under controlled conditions, welded stainless steel grating provides exceptional load-bearing capacity, structural stability, and long-term durability.

Available in 304, 304L, 316, and 316L stainless steel grades, welded bar grating performs reliably in environments exposed to moisture, chemicals, saltwater, and extreme temperatures. It is widely used for walkways, platforms, trench covers, drainage systems, offshore facilities, wastewater treatment plants, food processing facilities, and architectural projects.

Engineered to meet international quality standards, our stainless steel welded grating combines safety, strength, and low maintenance requirements, making it a preferred choice for contractors, engineers, distributors, and industrial project buyers worldwide.

Frequently Asked Questions (FAQ)

Q: What is the difference between welded bar grating and press-locked grating?

A: Welded bar grating is manufactured by permanently welding cross bars to bearing bars, providing excellent strength and load capacity. Press-locked grating is assembled through mechanical locking and is often preferred for architectural applications requiring a cleaner appearance.

Q: Which stainless steel grade is best for marine environments?

A: 316 and 316L stainless steel are recommended for marine and coastal applications due to their molybdenum content, which significantly improves resistance to chloride corrosion and saltwater exposure.

Q: Can you manufacture custom grating sizes?

A: Yes. We offer custom panel sizes, bearing bar dimensions, spacing configurations, edge treatments, and fabrication services according to customer drawings and project requirements.

Q: Is welded stainless steel grating suitable for food processing facilities?

A: Yes. 304L and 316L stainless steel grating are commonly used in food processing, beverage production, pharmaceutical facilities, and hygienic environments because of their corrosion resistance and ease of cleaning.

Q: What surface finishes are available?

A: Common finishes include mill finish, pickled and passivated finish, electropolished finish, and anti-slip serrated bearing bars for applications requiring enhanced traction.

Q: What is the typical delivery time?

A: Standard production orders are typically completed within 10-20 days, while custom fabrication projects may require additional time depending on specifications and order quantity.
