설명

High Quality Serrated Steel Grating
What Is Steel Grating?

Steel Grating, also known as open steel flooring or safety grating, is a high-strength structural material fabricated from load-bearing bars and cross connectors. It is engineered to provide a safe, durable, and versatile walking or standing surface across a vast range of industrial and architectural applications. Our grating is designed to offer superior slip resistance, excellent drainage and ventilation, and easy installation, making it an ideal solution for platforms, walkways, trenches, and stair treads in demanding environments.

Technical Specifications

Bearing Bar Spacing 30mm, 34.3mm (1-3/16"), 40mm, 41mm 30mm spacing is standard for walkways
Cross Bar Spacing 50mm, 100mm 100mm is most common
Surface Treatment Hot-Dip Galvanized, Painted, Powder Coated, Black (Ungalvanized) HDG to ASTM A123 is standard for carbon steel
Panel Standard Size 1000mm x 6000mm, 1000mm x 5000mm, Custom Sizes Can be cut to your exact dimensions
Load Classes Standard (15A/15B), Heavy-Duty, Special Duty According to ANSI/NAAMM MBG 531 or EN ISO 14122

Note: All specifications can be customized. Consult our engineering team for project-specific requirements.

Key Features
  • Exceptional Strength-to-Weight Ratio: Engineered to support heavy loads while remaining relatively lightweight, reducing structural support requirements.
  • Superior Safety: Serrated or plain surfaces provide excellent slip resistance, even in wet or oily conditions. The open design allows passage of light, air, and liquids, minimizing puddles and ice accumulation.
  • Long-Lasting Durability: Manufactured from high-quality carbon steel or stainless steel, with optional hot-dip galvanizing, powder coating, or other finishes for outstanding corrosion resistance.
  • Low Maintenance & Easy Installation: The modular design allows for quick cutting, fitting, and installation with standard tools. Its open structure prevents the accumulation of dirt, debris, and snow, minimizing cleaning needs.
  • Versatile & Aesthetic: Available in various materials, surface types, and finishes to meet functional requirements and architectural aesthetics.

Core Advantages
  • Safety Compliant: Manufactured in accordance with international standards (OSHA, NAAMM, EN ISO) for slip resistance and load-bearing capacity, ensuring a safe working environment.
  • Cost-Effective Solution: The combination of long service life, minimal maintenance, and fast installation leads to a significantly lower Total Cost of Ownership (TCO) compared to solid flooring alternatives.
  • Maximum Ventilation & Light Transmission: The open mesh design (typically 60-70% open area) allows air, light, and sound to pass through, ideal for mezzanines, plant floors, and screening applications.
  • Design Flexibility: Can be easily cut, welded, or bolted on-site to fit complex layouts, openings, and around existing structures.
  • Fire Resistant: Non-combustible material, contributing to improved fire safety in buildings and plants.
