Andy SimpsonIch bin ein langfristiger Partner dieser Fabrik. Ich bin auf einer Exkursion gewesen. Die Fabrik ist stark und die kratzende Qualität ist sehr gut. Ich arbeitete mit diesem kratzenden Lieferanten im Jahre 2017 zusammen. Was mich überraschte, war, dass diese Fabrik sehr stark war, und sie war auch eine der obersten lokalen kratzenden Fabriken. -
David ZhangMein Kunde sagte mir, dass es sehr glatt war. Die Lieferungsgeschwindigkeit ist auch, ich empfängt die Waren am 7. Tag des Auftrages sehr schnell. Und die Waren sind billig und bequem.

Produkt-Beschreibung
Heavy Duty Steel Grating manufactured according to international standards ensuring and reliability for heavy duty industrial
Our heavy-duty steel grating is a high-strength, durable structural component specifically engineered for heavy-load scenarios. Integrating excellent corrosion resistance, anti-slip performance, and ease of installation, this product serves a wide range of industrial, municipal, and commercial projects, providing stable structural support for heavy-duty operating environments. The following is a comprehensive introduction covering product specifications, material options, surface treatment, application scenarios, and core technical parameters.
1. Product Specifications
We offer both standard and fully customized steel grating products, manufactured in strict compliance with global mainstream standards including GB, ASTM, EN, and AS. Key specification details are as follows:
Bearing Bar: Common sizes include 25×3mm, 25×4mm, 30×5mm, 40×5mm, 50×5mm, and 75×10mm. The product is available in plain, serrated, and I-shaped configurations, with serrated types recommended for slippery environments. US standard sizes such as 1''×3/16'' are also available to meet diverse project requirements.
Bearing Bar Pitch: The overall range of bearing bar pitch is 12.5mm to 60mm, with 30mm and 40mm as the most commonly adopted specifications for industrial applications, effectively preventing mineral splashing and ensuring structural stability.
Overall Dimensions: Length can be customized from 1m to 12m, and width from 0.6m to 1.2m. Dimensional tolerance for length is ±5mm, and for width is ±3mm, with non-perpendicularity of bearing bars controlled within 10% of the bar width.
2. Material Options
Materials are scientifically selected based on on-site corrosion levels, temperature conditions, and load requirements to ensure stable performance and extended service life. The main material options are as follows:
Carbon Steel: Q235B grade, featuring a tensile strength of 370–500MPa and a yield strength of 235MPa, suitable for indoor heavy-duty scenarios and dry environments.
Stainless Steel: 304 and 316L grades, with a tensile strength of 205MPa–290MPa, offering excellent corrosion resistance and suitable for harsh environments such as chemical plants and coastal areas, enabling 15 years of maintenance-free service.
Low-Alloy Steel: High-strength low-alloy steel, designed for ultra-heavy load scenarios, with optimized structural design to enhance local compression resistance and adapt to extreme operating conditions.
3. Surface Treatment & Color Options
Surface treatment options are tailored to meet aesthetic and functional requirements, with the following specifications:
Hot-Dip Galvanizing: Silver-white, light gray, and pale yellow as standard colors, with passivation treatment available to enhance corrosion resistance, suitable for outdoor municipal projects and industrial workshops.
Powder Coating & Spray Painting: A full range of colors including industrial dark gray, black, light blue, and warning red, with UV-resistant and anti-aging formulas for outdoor applications, and customizable colors to match decoration styles for indoor scenarios.
Stainless Steel Natural Finish: Silver metallic luster, clean and hygienic, suitable for high-end commercial spaces and food processing factories, requiring no additional surface treatment.
4. Application Scenarios
The heavy-duty steel grating is widely applied as a core structural component in industrial and civil engineering, with specific applications in the following fields:
Industrial Sector: Petrochemical facilities, power stations, mining sites, automobile factories, and logistics warehouses, used for operating platforms, equipment support frames, trench covers, and heavy machinery areas, capable of bearing dynamic loads from forklifts and cranes.
Municipal Engineering: Bridges, overpasses, pedestrian paths, drainage channels, and parking lots, serving as floor plates, drain covers, and stair treads, balancing anti-slip safety and corrosion resistance.
Special Environments: Port terminals, coastal areas, chemical corrosion zones, and high-temperature workshops, with customized solutions provided to ensure stable operation under extreme conditions.
5. Core Technical Parameters
All key technical parameters comply with international standards to ensure safety, stability, and long-term performance:
Load-Bearing Performance: Standard heavy-duty type: static load of 1000–2000kg/m²; extra-heavy duty type: static load exceeding 2000kg/m². Uniform distributed load ≥5kN/m², concentrated load ≥20kN, with a 20%–30% safety margin for dynamic loads. Grade B heavy-duty grating supports a maximum span of 1.5m with a concentrated load of up to 30kN.
Corrosion Resistance: Hot-dip galvanized coating thickness ≥80μm, service life of over 15 years in conventional environments; 316L stainless steel provides long-term corrosion resistance, with passivation treatment available to further enhance anti-corrosion performance.
Welding Quality: Automatic welding technology is adopted, with weld strength reaching over 90% of the base material, free from cracks, pores, and other defects. The height difference between cross bars and bearing bars is controlled within 1mm, and cross bar edge overhang is limited to 2mm.
Executive Standards: GB/T 700, ASTM A36/A123, EN 10025, AS 1657, YB/T 4001.1-2007.
Product Weight: 30–100kg/m², calculated based on material density and structural size, with customizable weight options available upon request.
We implement strict full-process quality control from raw material inspection to finished product delivery. All steel grating products can be customized in size, material, and color to meet unique project requirements. With high mechanical strength, long service life, convenient installation, and low maintenance costs, our products provide reliable structural solutions for global heavy-duty industrial projects.
