Key Features & Technical Advantages
- High Load-Bearing Capacity: The 30x5mm flat bars provide substantial strength for heavy traffic and equipment loads. Combined with 12x5mm cross bars at 50mm spacing, the grating offers excellent distribution of point loads.
- Corrosion Resistance: Full hot-dip galvanizing ensures protection against rust, moisture, chemicals, and UV exposure. Suitable for outdoor, marine, or harsh industrial environments.
- Slip Resistance: The open mesh design with serrated flat bar options (available upon request) enhances grip even in wet or oily conditions, improving workplace safety.
- Easy Installation & Maintenance: Lightweight yet strong panels can be cut, welded, or bolted on-site. Minimal cleaning required due to self-draining openings.
- Versatile Applications: Ideal for industrial flooring, walkways, platforms, trench covers, catwalks, mezzanines, drain covers, and ventilation grilles in factories, warehouses, power plants, refineries, and commercial buildings.
- Consistent Quality: Manufactured under ISO 9001 processes – each weld is tested, and every panel is checked for flatness, size tolerance, and galvanizing thickness.
- Customization Available: Flat bar dimensions, cross bar spacing, panel length/width, and surface treatment (painted or galvanized) can be tailored to your project requirements.
Benefits for Your Business
- Reduced Maintenance Costs: The durable galvanized coating eliminates frequent repainting or replacement, saving long-term operating expenses.
- Improved Safety Compliance: Meets standard load requirements for industrial grating; optional serrated bars help prevent slips and falls.
- Fast Lead Times: With 101–200 employees and efficient production lines, we can handle bulk orders with delivery via Port of Tianjin or Qingdao within 15–30 days.
- Global Market Experience: Our products are exported to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, ensuring we understand diverse customer needs.

Frequently Asked Questions (FAQ)
- What is the load capacity of this 30x5mm grating? Load capacity depends on span and flat bar spacing. Typically, a 30x5mm flat bar at 100mm pitch can support uniform loads of 5–10 kN/m² for spans up to 1 meter. We can provide detailed load tables upon request.
- Can the mesh size be customized? Yes. We can adjust flat bar spacing (e.g., 50mm, 75mm, 150mm) and cross bar spacing (e.g., 33mm, 40mm, 100mm) to meet your specific open area or load requirements.
- Is the galvanizing compliant with international standards? Our hot-dip galvanizing process follows ASTM A123 / A123M or EN ISO 1461, ensuring a minimum coating thickness of 65 microns on flat bars. A mill certificate is available.
- What surface treatments are available besides galvanized? We offer painted (epoxy or polyurethane), plain (black steel), or powder-coated finishes. However, the standard for this product is hot-dip galvanized.
- How long does delivery usually take? For standard sizes and quantities, production takes 10–15 working days. Larger orders or custom sizes may require 20–30 days. We ship from Tianjin or Qingdao port.
- Can I get a sample before placing a bulk order? Absolutely. Free samples (500x500mm piece) are available for evaluation; you only pay for shipping.
- Do you provide serrated flat bars for better anti-slip? Yes, serrated flat bars (cross-hatched pattern) are an option to enhance slip resistance, especially in wet or oily environments.
- What is the minimum order quantity (MOQ)? MOQ for standard panels is 10 square meters. Custom sizes require a minimum of 20 square meters. Smaller quantities are negotiable for trial orders.
