Steel grating is a robust metal grid structure fabricated by welding or interlocking steel bearing bars and cross bars, creating high-strength open flooring systems with superior load capacity, ventilation, and drainage properties. As a trusted steel grating manufacturer, Tianhe Grating produces industrial steel grating capable of supporting loads up to 5 tons per square meter, making it the preferred choice for demanding applications in petrochemical, manufacturing, and infrastructure projects. Our galvanized steel grating and heavy duty steel grating products combine exceptional structural integrity with corrosion resistance, delivering reliable performance in the harshest operating environments.
Types of Steel Grating: Welded, Press-Locked & Serrated Designs
Tianhe Grating offers four primary steel bar grating configurations to meet diverse engineering requirements. Welded steel grating features bearing bars and cross bars fusion-welded at every intersection, providing maximum strength for heavy industrial loads and high-traffic walkways. Press-locked steel grating utilizes a mechanical interlocking process where cross bars are pressed into pre-punched slots in bearing bars, creating economical solutions for medium-duty applications. Swage-locked steel grating employs a unique swaging technique that permanently deforms cross bars into bearing bar slots, offering enhanced structural rigidity without welding. Serrated steel grating incorporates notched bearing bar surfaces that deliver exceptional anti-slip performance, critical for wet environments and inclined platforms. Each grating steel type is available in custom bearing bar dimensions ranging from 20×3mm to 65×5mm, with cross bar spacing options of 50mm, 100mm, or customer-specified intervals.
Quality Standards & Manufacturing Excellence
Our carbon steel grating production adheres to international standards including YB/T4001-1998 (China), BS4592-1-1995 (British Standard), and ANSI/NAAMM MBG 531 (North American specification). We fabricate steel floor grating from premium-grade Q235, SS400, and A36 carbon steel, ensuring consistent material properties and weldability. Surface treatments include hot-dip galvanized steel grating with zinc coating thickness exceeding 86 microns for 25+ year corrosion protection, electro-galvanized finishes for indoor applications, and industrial powder coating in custom colors. Every batch undergoes rigorous ISO9001-certified quality control, including load testing, dimension verification, and zinc adhesion analysis. Our advanced robotic welding systems deliver uniform penetration across all bearing bar intersections, eliminating weak points common in manual fabrication processes.
Proven Applications Across Industrial Sectors
Steel grating is used for critical infrastructure in six major application categories. In oil and gas facilities, our platform grating provides safe access flooring for drilling rigs, refinery catwalks, and offshore structures where fire resistance and drainage are paramount. Chemical plants rely on our steel walkway grating for corrosion-resistant pedestrian bridges and equipment access platforms exposed to acidic environments. Municipal projects utilize our drainage steel grating and trench covers to manage stormwater runoff in parking structures and roadway drainage systems. Warehouse mezzanine installations benefit from our floor grating steel solutions that maximize natural light penetration and air circulation while supporting multi-ton pallet loads. Stair treads fabricated from serrated steel bar grating ensure worker safety in manufacturing facilities and power plants. Offshore platform decking applications demand our marine-grade galvanized steel grating with enhanced zinc coating for saltwater exposure resistance.
