As a leading manufacturer with over 25 years of expertise, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Welded Steel Bar Grating for Walkway and Platform Flooring in Chemical Plant Applications. Engineered for the harshest industrial environments, this grating combines superior strength with corrosion resistance to ensure safe and durable flooring solutions. With an annual export value exceeding US$5 million and shipments to over 15 countries, our products are trusted by global clients in North America, Europe, and Asia.
Our welded steel bar grating is specifically designed to meet the rigorous demands of chemical plants, where exposure to corrosive substances, heavy loads, and slippery conditions is common. The open-grid structure allows for efficient drainage of liquids, reduces the accumulation of debris, and provides excellent ventilation. Each panel is manufactured using advanced electric resistance welding technology, ensuring consistent weld quality and long-term structural integrity.
Choose from a variety of material options, including Q235 mild steel and stainless steel, with surface treatments such as hot-dip galvanizing, epoxy coating, or painting. Our panels are fully customizable in size, bar spacing, and thickness to match your specific load requirements and site conditions. Whether for walkways, platforms, stair treads, or trench covers, this grating delivers reliable performance in extreme chemical environments.
Key Features & Technical Specifications
- Superior Corrosion Resistance: Hot-dip galvanized coating (Z600+ grade) provides long-lasting protection against acids, alkalis, and moisture. Optional stainless steel (304/316L) for extreme chemical resistance.
- High Load Capacity: Bearing bars are available in thicknesses from 3mm to 6mm, with cross bars at regular intervals to distribute weight evenly. Suitable for pedestrian, light vehicle, and industrial equipment traffic.
- Slip Resistance: Serrated or plain bearing bars available; open grid design prevents water and oil buildup, reducing slip hazards.
- Easy Maintenance & Drainage: Open area of up to 70% allows liquids, dirt, and debris to fall through, minimizing cleaning efforts and preventing pooling.
- Customizable Dimensions: Panel length up to 6 meters, width up to 1.5 meters, with bar spacing options of 30mm, 40mm, or 50mm. Custom shapes and cutouts available.
- Simple Installation: Lightweight yet strong design; can be welded, bolted, or clipped onto supporting structures. Pre-cut panels reduce on-site labor.
- Versatile Applications: Ideal for chemical plant walkways, platform flooring, catwalks, mezzanines, trench covers, and stair treads.

Why Choose Our Welded Steel Bar Grating?
- Chemical Plant Expertise: Our grating is engineered to withstand exposure to corrosive chemicals typically found in refineries, processing plants, and storage facilities. The hot-dip galvanized coating offers excellent resistance to rust and chemical attack.
- Precision Manufacturing: Using advanced CNC welding machines, each joint is precisely controlled for consistent strength and durability. Our production capacity exceeds 5000 panels per month, ensuring timely delivery.
- Cost-Effective Solution: Compared to solid steel plates or fiberglass grating, our welded bar grating offers a lower cost per square meter while maintaining high load-bearing performance. The open design also reduces material weight, saving on shipping and support structure costs.
- Safety Compliance: Anti-slip serrated bars are available as an option to meet international safety standards. The open grid prevents accumulation of flammable liquids, reducing fire hazards in chemical environments.
- Eco-Friendly: Galvanized steel is 100% recyclable, and our manufacturing process minimizes waste. The grating’s long service life reduces the need for frequent replacements, lowering environmental impact.

Frequently Asked Questions
-
Q: What is the typical lifespan of your welded steel bar grating in a chemical plant environment?
A: With proper hot-dip galvanizing (Z600), the grating can last 15–20 years in moderate chemical exposure. For aggressive environments, we recommend stainless steel (304/316L) which offers even longer service life. -
Q: Can you provide custom sizes and shapes?
A: Yes, we offer full customization. You can specify panel dimensions, bar spacing, thickness, and cutouts for pipes or columns. Provide a drawing or template, and we will produce accordingly. -
Q: What surface treatment options do you offer for chemical resistance?
A: Standard options include hot-dip galvanizing (Z600), epoxy coating, and powder painting. For the highest chemical resistance, we recommend stainless steel 316L with a mill finish. -
Q: How is the grating installed?
A: Installation can be done by welding to steel supports, using bolts and clips, or by placing the grating into pre-welded frames. We can provide installation accessories and guidance. -
Q: What is the load-bearing capacity of your grating?
A: Load capacity depends on bar thickness, height, and spacing. For example, a standard 30mm×5mm bar with 40mm spacing supports up to 5 kN/m² (medium duty). Heavy-duty versions can handle 10 kN/m² or more. We can calculate based on your specific requirements. -
Q: Do you offer anti-slip surfaces?
A: Yes, we offer serrated (toothed) bearing bars that provide enhanced slip resistance, ideal for wet or oily environments. Plain bars are also available. -
Q: What is the minimum order quantity?
A: MOQ is typically 50 square meters for standard panels. Custom orders may have different requirements. For small quantities, please contact us to discuss availability. -
Q: How long does delivery take?
A: For standard sizes, production takes 15–20 working days. Custom orders may require 25–30 days. Shipping time depends on the destination port. We can arrange express or sea freight.
