Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted partner in industrial grating solutions since 1998. Our Bar Grating for Floor Making in Wastewater Treatment is precision-engineered from high-quality galvanized steel, featuring robust 30x3mm bars with 50x100mm spacing to deliver exceptional drainage and load-bearing performance. Designed specifically for harsh wastewater environments, this grating combines durability with efficient water flow, ensuring safety and longevity in treatment plants, walkways, and drainage channels.
Our factory, with over two decades of experience, exports to markets across North America, South America, Europe, Asia, Africa, and Oceania, generating annual export revenues of US$5-10 million. We understand the critical demands of wastewater treatment facilities – corrosion resistance, anti-slip surfaces, and easy maintenance. That’s why every bar grating we produce undergoes rigorous quality control to meet international standards.
Key Features & Technical Specifications
- Material: Hot-dipped galvanized steel – superior corrosion resistance for wet and chemical environments.
- Bar Size: 30mm height x 3mm thickness – optimal strength-to-weight ratio for medium to heavy loads.
- Spacing: 50mm center-to-center (bearing bars) x 100mm center-to-center (cross bars) – balanced drainage and debris passage.
- Surface: Serrated or plain top – anti-slip design for worker safety, even when wet.
- Load Capacity: Suitable for pedestrian walkways, light vehicle traffic, and equipment platforms in wastewater plants.
- Drainage Efficiency: Open area ratio of approximately 50% – rapid water flow, reducing ponding and slip hazards.
- Customization: Available in various panel sizes, shapes, and cutouts to fit tanks, trenches, and channels.
- Finish: Uniform galvanized coating – no sharp edges, easy to install with standard tools.

Advantages for Wastewater Treatment Flooring
- Corrosion Resistance: The hot-dipped galvanized coating forms a protective barrier against moisture, chemicals, and biological agents common in wastewater. This extends service life significantly compared to untreated steel.
- Efficient Drainage: The 50x100mm spacing allows solids and liquids to pass through quickly, preventing clogging and reducing the need for manual cleaning. This is critical for aeration basins, filter floors, and sludge channels.
- Safety First: Serrated surfaces provide reliable traction even in wet, oily, or algae-covered conditions. Workers can move confidently on walkways and platforms.
- Easy Installation & Maintenance: Lightweight yet strong, these gratings can be cut and fitted on-site with standard tools. They require no painting or special treatment – simply wash down with water.
- Load-Bearing Reliability: Designed to support static and dynamic loads typical of treatment plant operations including maintenance personnel, small equipment, and occasional light vehicles.
- Cost-Effective: The galvanized finish eliminates the need for frequent replacement, reducing lifecycle costs. Our factory-direct pricing ensures competitive rates without compromising quality.

Frequently Asked Questions
-
Q: What is the load capacity of this 30x3mm bar grating?
A: The load capacity depends on the span (distance between supports). For a typical 600mm span, the grating can safely support up to 4 kN/m² (pedestrian load). For specific applications, we provide load tables based on your support spacing. Please consult our engineering team. -
Q: Can this grating be used in corrosive environments like chemical tanks?
A: Yes, the hot-dipped galvanized coating provides excellent resistance to corrosion from moisture, mild acids, and alkalis found in wastewater. For highly aggressive chemicals, optional epoxy coating or stainless steel variants are available upon request. -
Q: How is the grating installed – does it require welding?
A: Installation is simple. Gratings can be secured using clips, hold-down brackets, or welding to supporting structures. We provide installation accessories (clips, bolts) if needed. No special tools are required. -
Q: What are the standard panel sizes, and can you cut them to custom dimensions?
A: Standard panels are 6m x 1m, but we can cut to any length and width up to 8m. Custom cutouts for pipes, columns, or manholes are also available. Provide a drawing and we will fabricate precisely. -
Q: Is the surface anti-slip? What about in wet conditions?
A: We offer serrated (toothed) top surfaces that provide excellent slip resistance even when greasy or wet. The serrations are formed during manufacturing and are an integral part of the bar, not an add-on coating. -
Q: What is the lead time for an order?
A: For standard sizes, lead time is 15-20 days after order confirmation. Custom orders may take 20-25 days depending on complexity. We ship via sea or air as per your preference. -
Q: Do you provide samples before bulk order?
A: Yes, we can provide small samples (e.g., 300x300mm) for evaluation. The sample cost is deducted from the final order. Contact us for details. -
Q: How does the galvanized coating hold up over time?
A: Hot-dipped galvanizing creates a metallurgically bonded zinc-iron alloy layer that protects the steel. In typical wastewater environments, the coating can last 20-30 years before first maintenance is needed. The exact lifespan depends on exposure conditions.
