As a trusted manufacturer with over 20 years of experience, Anping County Boli Hardware Wiremesh Products Factory (established in 1998) proudly presents our 304 Stainless Steel Bar Grating with welded construction and a precise 19x100mm mesh. This product is specifically engineered for demanding environments where corrosion resistance and structural integrity are paramount. Our grating offers a reliable solution for industrial flooring, platforms, and walkways, combining durability with easy maintenance.
Each panel is fabricated from high-quality 304 stainless steel, ensuring excellent resistance to moisture, chemicals, and extreme temperatures. The welded construction provides a robust, uniform grid that distributes loads evenly, while the 19x100mm mesh opening offers optimal balance between strength and drainage. Whether you need a standard size or a custom dimension, our factory can tailor the product to your exact specifications.
Key Features & Benefits:
- Superior Corrosion Resistance: 304 stainless steel is ideal for wet, acidic, or saltwater environments, making it suitable for food processing plants, chemical factories, marine applications, and offshore platforms.
- Welded Construction: Each joint is fully welded at the intersection of bearing bars and cross bars, creating a monolithic structure that eliminates loosening or shifting under heavy loads.
- Precise 19x100mm Mesh: The 19mm center-to-center spacing of bearing bars and 100mm spacing of cross bars provides a stable walking surface while allowing debris, water, and light to pass through.
- High Load Capacity: Depending on bar thickness and height, the grating can support pedestrian, light vehicle, or heavy industrial loads. Custom designs are available for specific load requirements.
- Low Maintenance: The non-porous surface of stainless steel resists staining and bacteria growth, and the open design facilitates easy cleaning with water or steam.
- Customizable Options: We offer various bar profiles (flat, serrated, I-beam), surface treatments (plain, hot-dip galvanized, epoxy coated), and edge details (banding, cutouts) to meet your project needs.
- Slip Resistance: Serrated bars can be provided for enhanced traction in oily or wet conditions, improving workplace safety.
- Fire Resistance: Stainless steel is non-combustible, adding to the safety of the structure.

Detailed Product Advantages: Our 304 stainless steel bar grating is manufactured using advanced welding technology, ensuring consistent quality and dimensional accuracy. The material’s chromium content forms a passive oxide layer that self-heals in the presence of oxygen, providing long-term corrosion protection even when scratched. This makes it an excellent choice for food processing, pharmaceutical, wastewater treatment, and marine applications where hygiene and durability are critical. The open grating design allows for maximum light penetration and ventilation, reducing energy costs in indoor environments. Additionally, the lightweight nature of the grating simplifies handling and installation, lowering labor costs without sacrificing strength.
Trust & Experience: With an annual export value of US$5 Million - US$10 Million, our factory has supplied grating products to clients across North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and many other regions. We ship from major ports including Tianjin, Qingdao, Shanghai, and Foshan, ensuring timely delivery. Our 20+ years of manufacturing experience and in-house quality control guarantee that every panel meets your specifications. We are committed to providing customized solutions, quick turnaround, and competitive pricing.

Frequently Asked Questions (FAQ)
-
What is the difference between 304 and 316 stainless steel grating?
Both are austenitic stainless steels. 304 offers good corrosion resistance in most environments, while 316 contains molybdenum for enhanced resistance to chlorides and acids. For extremely corrosive environments (e.g., marine splash zones, chemical plants), 316 is recommended. Our factory can supply both grades. -
Can the grating be cut to custom sizes on site?
Yes, the grating can be cut with standard tools (e.g., angle grinder, plasma cutter) to fit irregular shapes. However, we recommend ordering custom sizes to minimize waste and labor. We can provide cutouts, notches, and banding per your drawings. -
What is the load capacity of this 19x100mm grating?
Load capacity depends on bearing bar height, thickness, and span. For example, a 30mm high x 3mm thick bar with 500mm span can support approximately 2 kN/m². We provide detailed load tables for each configuration. Please contact us with your specific requirements. -
How is the grating installed?
Typical installation methods include welding to support structures, using clips (saddle clips or J-clips), or embedding in concrete. We offer installation hardware and guidance. The grating should be secured at intervals of 300-500mm along the perimeter. -
Is the grating slip-resistant?
Standard flat bars can be slippery when wet. For better slip resistance, we recommend serrated (toothed) bearing bars, which provide excellent traction even in oily conditions. Serrated bars are available at no extra cost for most sizes. -
What surface treatments are available?
Standard is mill finish (pickled and passivated) for a clean, corrosion-resistant surface. We also offer hot-dip galvanizing for extra protection in harsh environments, or epoxy/polyester powder coating for color-coded areas. Please note that galvanizing is for carbon steel, not stainless steel; for stainless steel, we only provide mill finish or passivated surface. -
What is the minimum order quantity (MOQ)?
Our MOQ is typically 10 square meters for standard sizes. For custom dimensions or special requirements, MOQ may be higher. We can accommodate small orders for sample or prototype testing. -
How long is the delivery time?
Standard production takes 15-20 days after confirmation of order and payment. Custom orders may require 25-30 days. We ship via sea freight or air express depending on volume and urgency.
