Steel grating is a highly durable and versatile material constructed from bearing bars and crossbars, forming a robust grid pattern. This structure provides exceptional load-bearing capabilities and stability, making it a preferred choice for industrial, commercial, and architectural applications. Steel grating is manufactured using two primary methods: welded grating, where bars are fused at intersections for enhanced strength, and pressure-locked grating, where bars are mechanically locked under high pressure without welding.
Materials
- Carbon Steel: Known for strength and cost-efficiency; often galvanized for corrosion resistance.
- Stainless Steel: Offers excellent resistance to corrosion, suitable for chemical and sanitary environments.
- Aluminum: Lightweight and corrosion-resistant, ideal for marine and architectural applications.
- Galvanized Steel: Coated with zinc to improve durability and prevent rust.
- Fiberglass: A non-metallic, lightweight, and chemical-resistant alternative.
Types of Steel Grating
Flat Bar Grating:
Features: Smooth surface for easy movement.
Applications: Walkways, pathways, and equipment areas.
Serrated Grating:
Features: Serrated surface for enhanced slip resistance.
Applications: Wet or oily environments.
I-Bar Grating:
Features: I-shaped bars reduce weight while maintaining strength.
Applications: Load-bearing areas with material efficiency needs.
Serrated I-Bar Grating:
Features: Combines I-bar design with serrated surfaces for safety and efficiency.
Applications: Challenging environments requiring slip resistance and strength.
Specifications
- Bearing Bar Sizes: Widths range from 20 mm to 60 mm; thicknesses from 3 mm to 5 mm.
- Bearing Bar Pitch: Common options include 25 mm, 30 mm, 34 mm, and 40 mm.
- Crossbar Pitch: Typical ranges are 50 mm, 76 mm, and 100 mm.
- Surface Treatments: Available in self-color, galvanized, or painted finishes for durability and aesthetic appeal.
Applications
Industrial and Infrastructure:
- Flooring and Walkways: Durable surfaces for factories and workshops.
- Trench Covers and Drains: Efficient water flow management with high load capacity.
- Platforms: Stable maintenance and operation surfaces.
Commercial and Architectural:
- Stair Treads and Mezzanines: Ensures safety and support for multi-level structures.
- Balustrades and Facades: Enhances aesthetic appeal while providing strength.
- Sun Screens: Offers shading and ventilation.
Transport and Public Spaces:
- Bus Stations and Airports: Used for flooring and barriers in high-traffic areas.
- Port Platforms: Resilient under heavy loads and marine conditions.
Residential and Safety Barriers:
- Fences and Balconies: Combines security with design aesthetics.
- Safety Barriers: Protects and delineates areas effectively in civil and agricultural projects.
