Standard Steel Grating Supplier - China

Standard steel gratings, also known as Open Steel Grating, usually has a length ranging from 1000mm to 7500mm and a width ranging from 993 to 1000mm.

Bearing Bars range from 20*3mm to 150*10mm.

Known globally by multiple names—including steel metal grating, metal grating, bar grating, and ss grating—our products are available in multiple surface finishes: hot-dip galvanized (galv grating), painted, and stainless steel.

These treatments enhance corrosion resistance, making them ideal for harsh settings such as chemical plants, marine environments, or municipal projects requiring stainless steel drain grating.

What Is Standard Steel Grating?

Standard Steel Grating, also known as bar grating or open steel grating, is a load-bearing steel product widely used in industrial flooring, drainage covers, walkways, platforms, and architectural applications.

Manufactured using high-strength carbon steel or stainless steel, it delivers superior load capacity and corrosion resistance.

Our grating meets international safety standards, including OSHA, EN 1090, and AS/NZS, and is available with hot-dip galvanized (galv grating), painted, or stainless steel (ss grating) finishes.

Technical Parameters

1 - Material

(1)Primary Material: High-grade Q235 carbon steel (equivalent to ASTM A36), balancing cost-efficiency and structural strength for general applications.

(2)Stainless Steel Options: 304/316 stainless steel, engineered for extreme corrosion resistance—perfect for stainless steel drain grating in food processing plants, coastal areas, or high-humidity zones.

Marketed as ss grating for quick industry recognition.

2 - Bearing Bar Specifications

(1)Thickness: 3mm, 4mm, 5mm, 6mm.

(2)Width: 20mm, 25mm, 30mm, 32mm, 35mm, 40mm, 45mm, 50mm, 60mm (international specs for varied loads, including popular steel bar grating configurations like 30mm width for heavy-duty floors).

(3)Global Combinations: Common choices include 30mm width × 5mm thickness for metal grating floor systems and 25mm width × 3mm for pedestrian-friendly walkways.

3 - Cross Bar Specifications

(1)Diameter: 6mm, 8mm, 10mm twist bars (for superior anti-slip in galv grating) or round bars

(2)Spacing: 50mm, 100mm (100mm spacing widely used in stainless steel drain grating and road safety steel bar grating applications).

4 - Surface Treatments

(1)Hot-Dip Galvanized (Galv Grating): compliant with ISO 1461 specifications, engineered to withstand harsh industrial and outdoor environments.

This corrosion-resistant grating solution ensures long-lasting performance with minimal maintenance, providing cost-effective durability for infrastructure applications.

(2)Painted: Customizable RAL colors for architectural integration, providing moderate corrosion protection for commercial metal grating floor projects.

(3)Stainless Steel Finish (SS Grating): Natural resistance to rust and chemicals, making it the top choice for hygienic environments (e.g., food processing) or stainless steel drain grating in marine settings.

5 - Load Capacity

(1)Light-Duty: Supports pedestrian traffic (walkways, stair treads) with safe load limits up to 300kg/m²—perfect for metal grating floor in retail or office spaces.

(2)Heavy-Duty: Handles vehicle/equipment loads (industrial platforms, road safety grating, steel bar grating barriers) with capacities exceeding 5, 000kg/m².

(3)Certified Load Tables: Available for all configurations, compliant with OSHA (USA), EN 1090 (EU), and AS/NZS (AU/NZ) standards.
