Company Profile

Industrial steel grating features standard cross spacing for balanced load performance and cost efficiency.

Steel grating is a high-performance, multifunctional structural material widely applied in modern industrial construction, municipal infrastructure and civil commercial engineering. It integrates customizable structures, diversified material options, versatile surface finishing, broad application compatibility and standardized technical indicators, delivering comprehensive performance advantages superior to traditional building materials.

With stable structural rigidity, strong environmental adaptability and excellent long-term cost efficiency, steel grating has become an indispensable core component for global engineering projects.

Customizable and standardized specifications constitute the core advantage of steel grating. Featuring flexible adjustable structural parameters, it covers universal standard models and personalized non-standard customization to meet diverse load-bearing, installation and construction demands.

Load-bearing bars are available in complete mainstream specifications from 20×3mm to 50×5mm, with spacing adjustable between 20mm and 100mm, among which 30mm and 40mm are universal industry standards for conventional engineering. Matching twisted square steel cross bars come in 6×6mm, 8×8mm and 10×10mm sizes, with 50–200mm adjustable spacing. The 100mm standard cross bar spacing strikes an optimal balance between load capacity and economic benefits.

Standard panels measure 1–1.2m in width and 2–6m in length, while custom sizes for large platforms, stair treads and special structures can be produced per project drawings, adapting flexibly to complex construction conditions.

Diversified material configurations enable steel grating to adapt to differentiated and harsh working environments. Three premium industrial materials are adopted to cover conventional dry conditions, corrosive scenarios and load-limited projects with targeted performance.

Q235 and Q355 carbon steel delivers stable mechanical strength and prominent cost performance, suitable for indoor dry and low-humidity scenarios such as workshops and warehouses after professional anti-corrosion treatment.

304, 316 and 316L stainless steel provides outstanding corrosion resistance: 304 fits outdoor and mild chemical environments, while 316 and 316L grades resist seawater, acid and alkali erosion, ideal for marine facilities, chemical plants and food processing factories.

Ultra-light aluminum alloy grating, weighing only one-third of ordinary steel with inherent anti-corrosion performance, perfectly suits load-sensitive projects including aerospace auxiliary facilities, urban pedestrian bridges and coastal engineering.

Multiple professional surface treatment processes endow steel grating with dual strengths of protective performance and aesthetic versatility. Without fixed inherent color, its appearance and environmental durability depend entirely on precision surface finishing technologies.

Hot-dip galvanization is the mainstream industrial process, forming a uniform silver-gray zinc coating over 85μm thick that ensures 15–20 years of reliable outdoor anti-corrosion performance, widely used in industrial and municipal infrastructure projects.

Powder coating supports personalized customization of red, blue, green, yellow, gray and other colors, with wear-resistant and UV-stable surfaces that resist aging and fading for commercial buildings and landscape facilities.

Spray coating enables flexible color matching for indoor low-wear scenarios with unified color requirements, though its durability is relatively limited. Natural stainless steel finish retains a premium metallic silver texture without extra coating, complying with modern architectural aesthetics and strict hygienic standards for sterile operating environments.

With superior structural performance and wide environmental adaptability, steel grating applies to a full range of scenarios covering general industrial, municipal, civil commercial and harsh special environments.

Industrially, it is widely used for factory platforms, anti-slip walkways, stair treads, equipment supports and offshore drilling platforms, ensuring safe and stable operation in heavy-duty conditions.

For municipal infrastructure, it serves bridge decking, road drainage grates, sidewalk facilities, subway stations and sewage treatment plants. Its open-grid structure enables efficient water and debris circulation, effectively preventing blockages and reducing long-term maintenance costs.

In civil and commercial buildings, it is commonly installed in mall atriums, underground garages, pedestrian bridges, rooftop terraces and balcony flooring, balancing structural stability and modern architectural aesthetics. Customized grating solutions also cater to special scenarios, including anti-corrosion models for marine and chemical projects, food-grade stainless steel for food processing industries, and serrated anti-slip grating for fire escape passages.

Standardized core technical parameters guarantee steel grating’s long-term structural safety and operational stability in engineering applications. Manufactured in strict compliance with OSHA, EN 14411 and other international standards, all products feature precise and reliable performance indicators.

The load capacity is scientifically graded: 5–10kN/m² for pedestrian-only areas and 15–25kN/m² for light vehicle passage, meeting graded load demands of different projects. The serrated anti-slip structure achieves a wet-surface slip resistance coefficient of ≥0.5, effectively preventing slip hazards and ensuring workplace safety.

Matched with diverse materials and surface treatments, the product resists oxidation, mild chemical erosion and seawater corrosion to adapt to various harsh environments. Different material grades feature differentiated unit weights, offering flexible solutions for structural load control, transportation and on-site installation.

Welded grating provides a joint shear strength of ≥3.6kN, while mechanically locked grating adopts a modular detachable structure for convenient disassembly, repeated use and lower comprehensive project costs.

In summary, steel grating stands out in modern engineering for its customizable structures, diverse material adaptability, flexible aesthetic finishes, wide application coverage and stable reliable performance.

It fully meets the functional and safety standards of conventional and harsh engineering scenarios while delivering excellent long-term cost performance. As a high-reliability and field-proven structural material, steel grating remains an indispensable choice for global construction and industrial engineering projects.
