Hengshui Ruibin New Materials LLC, established in 2019 as a dedicated manufacturer in Hebei, China, brings you the Press Locked Galvanized Steel Grating Q235 — a robust and versatile solution for heavy-duty industrial applications. Our 1,000–3,000 sqm factory and team of 101–200 experienced workers ensure consistent quality and timely delivery. This grating combines the strength of Q235 steel with a hot-dip galvanized finish, making it both corrosion-resistant and low-maintenance. Whether you need secure walkways, drainage covers, or platform flooring, our press locked design delivers reliable performance without welding or loose parts.
Key Features & Technical Specifications
- Material: Premium Q235 carbon steel – offers high tensile strength and excellent weldability.
- Flat Bar Dimensions: 20mm height × 5mm thickness – provides ample load-bearing capacity while keeping weight manageable.
- Grid Pattern: 30mm (bearing bar spacing) × 100mm (cross bar spacing) – an ideal balance of openness for drainage and strength for foot traffic.
- Locking Mechanism: Press locked (mechanical interlock) – no welding or rivets needed; bars are permanently pressed together using high-pressure tools, ensuring a rigid and stable structure.
- Anti-Slip Design: Twisted cross bars create raised edges that improve traction even in wet or oily conditions; serrated flat bars are also available upon request.
- Surface Finish: Hot-dip galvanized coating (thickness ≥ 85µm) – protects against rust and extends service life in outdoor or harsh environments.
- Custom Sizes: Panels can be cut to exact dimensions or fabricated with perimeter bands, cutouts, and other modifications as needed.
- Load Capacity: Suitable for light, medium, and heavy industrial loads depending on bearing bar spacing and thickness; please consult our technical team for specific load tables.

Advantages & Customer Benefits
- No Welding Required: The press-lock method eliminates heat-affected zones, reducing the risk of corrosion and maintaining structural integrity.
- Easy Installation: Lightweight panels can be handled by two workers, and the modular design allows quick assembly with standard supports.
- Excellent Drainage: Open area of approximately 60–70% allows water, snow, and debris to pass through, keeping surfaces clean and safe.
- Long Service Life: Hot-dip galvanizing provides long-term protection against rust, even in coastal or chemical environments.
- Enhanced Safety: Anti-slip cross bars reduce slip hazards, making it ideal for oily or wet industrial floors.
- Cost-Effective: Compared to stainless steel, galvanized Q235 offers a similar lifespan at a lower initial cost.
- Eco-Friendly: Steel is 100% recyclable, and the galvanizing process adds no harmful volatile organic compounds (VOCs).

Frequently Asked Questions (FAQ)
-
Q: What is the difference between press-locked and welded grating?
A: Press-locked grating uses mechanical pressure to join cross bars to bearing bars, eliminating the need for welding. This results in a smooth, flat surface with no weld spatter and reduces the risk of corrosion at joints. -
Q: Can this grating be used outdoors without additional protection?
A: Yes, the hot-dip galvanized coating provides excellent corrosion resistance for outdoor applications. For extremely harsh environments (e.g., acidic or marine), we can recommend additional coatings or alternative materials upon request. -
Q: What is the load capacity of a 20×5mm bar with 30×100mm grid?
A: Load capacity depends on span, support conditions, and deflection limits. Generally, this size supports light to medium pedestrian and light vehicle loads. Please contact us with your span and required load for a detailed calculation table. -
Q: Can you cut the panels to a specific size?
A: Absolutely. We offer custom cutting, notching, and banding to your exact dimensions. Simply provide a drawing or specifications. -
Q: Do you supply matching clips or fasteners?
A: Yes, we can provide saddle clips, U-bolts, or other mounting hardware as optional accessories. Please inquire about availability. -
Q: Is the anti-slip feature standard or optional?
A: The twisted cross bar design is standard for the press-locked grating, providing good slip resistance. For even higher traction, we can supply serrated (toothed) bearing bars as a customization. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is typically 10 sheets, but we can accommodate smaller trial orders for new customers. Contact us for details. -
Q: How long does shipping take to my country?
A: Production usually takes 15–25 working days. Shipping time depends on the destination; from Tianjin or Qingdao to most international ports takes 20–40 days for sea freight.
