Stainless Steel Pressure Welded Grating Plate with High Load-Bearing Capacity

Deskripsi

Platform Stainless Steel Grating Pressure Welded Grating Plate
Galvanized grating, also called galvanized steel grating or galvanized steel bar grating, refers to steel bar grating made of mild carbon steel through hot dipped galvanized surface treatment. Mild carbon steel provides an economical, high strength solution for most industrial and commercial applications, while hot dipped galvanized surface treatment supplies excellent corrosion resistance performance for durability.
Product Specifications
Structure: Welding with flat steel and cross/round bars with specific spacing
Features: High strength, light structure, high load bearing capacity
Surface: Hot dipped zinc coating provides excellent anti-corrosion properties
Load Bearing Flat Bar Size Thickness ≥3mm, Depth ≥19mm
19×3, 19×5, 20×3, 20×5, 25×3, 25×4, 25×4.5, 25×4.7, 25×5…40×6, 40×8, 40×10,…90×6… Various sizes available
Pitch of Load Bearing Flat Bars (mm) 12.5, 15, 20, 30, 30.6, 32.5, 34, 34.8, 35.3, 40, 60, 80...
Pitch of Cross Bars (mm) 38.1, 50, 50.8, 70, 75, 80, 99, 100, 101.6, 102...

Steel Grating Types
1. Plain Type: One of the most widely used gratings, suitable for flooring, sidewalk, drainage pit cover, stair tread, etc.

2. Serrated Type: Better non-skid properties and safety compared with plain grating.

3. I-Shape Type: Lighter, more economical and practical compared with plain grating.
Key Features
  • Superior Anti-Slip Performance: Features specially designed serrated bearing bars or anti-slip plate surfaces that provide outstanding traction, ensuring safe passage even in wet, oily, or icy conditions.
  • Integrated Safety Design: Can be customized with integrated nosing strips, warning strips, or kick plates to form a complete fall protection system, complying with the most stringent safety regulations.
  • Excellent Drainage & Ventilation: The open mesh structure ensures water, snow, dirt, and debris do not accumulate on the tread surface, keeping stairs clean and dry while reducing cleaning and maintenance costs.
  • High Strength & Lightweight: Significantly lighter than solid steel plate treads (up to 50%-70% weight reduction), lowering the load on the stair support structure and easing transportation and installation.
  • Flexible & Quick Installation: Offers various installation options including bolted, welded, or clip-on systems, allowing for easy adaptation to diverse stair structures and on-site conditions.

Frequently Asked Questions
What is the standard spacing for bearing bars?
Standard spacings are typically 30mm or 40mm (center-to-center), though 19-W-4 (1-3/16" spacing) is a common North American industrial standard.
What is "19-W-4" nomenclature?
This is a standard designation: 19: Spacing of bearing bars in 16ths of an inch (19/16"). W: Means the type is "Welded." 4: Spacing of cross bars in inches (4").
How much load can steel grating handle?
Load capacity depends on the bearing bar size (height and thickness) and the span length. Manufacturers provide "Load Tables" which specify allowable uniform loads and concentrated loads.
Is steel grating slip-resistant?
Yes, particularly the serrated type. For high-traffic pedestrian areas, serrated grating meets most international anti-slip safety standards (like OSHA or DIN 51130).
