Steel Grating

Material Options

Mild Carbon Steel (A36 / S235 / Q235): Standard choice for industrial platforms and walkways. Finished with hot-dip galvanizing (HDG) or high-quality paint for corrosion protection and visual appeal.

Stainless Steel (SS304 / SS316): Naturally resistant to corrosion, perfect for chemical, food processing, or outdoor applications requiring long-term durability.

Surface Treatments

Hot-Dip Galvanized: Complies with ISO 1461, ASTM A123, and BS 729 standards. Zinc layer thickness ensures up to 20 years of corrosion resistance in harsh environments.

Powder Coating / Painted Finish: Durable, anti-corrosive, and decorative; suitable for indoor or semi-outdoor installations.

Plain / Self-Color: Untreated steel for dry indoor areas where surface protection is not critical.

Hengchen's expertise ensures the right material and surface treatment for your application, minimizing maintenance costs and extending service life.

Grating Types

Welded (Electro-Forged): Rectangular bearing bars welded to twisted cross bars, widely used in industrial walkways and platforms.

Swage-Locked: Hollow tube cross bars inserted into pre-punched bearing bars and hydraulically compressed; cross bars recessed for smooth, attractive finish.

Dovetail Pressure-Locked: Deep rectangular cross bars configured in an “egg-crate” pattern, deformed under high hydraulic pressure for superior load-bearing.

Bearing Bar Options

Flat / Plain Bar: Versatile and widely used.

Serrated Bar: Enhanced anti-slip performance for stair treads and walkways.

I-Bar: High-strength option for heavy-duty applications; popular in Asia (China, Korea, Japan, Taiwan).

Hengchen can produce custom sizes, including 1×6 m sheets or 3×20 ft panels, to meet any project requirement. Heavy-duty gratings with bearing bars ≥60×5 mm and shorter spacing are available for demanding applications.

At Hengchen, we understand that every industrial project has unique requirements. Our mission is to provide steel grating solutions that not only meet specifications but also solve real-world challenges for our customers.

1. Custom Sizes and Specifications

Many projects require non-standard grating dimensions or heavy-duty load capacities. Hengchen can manufacture steel grating to exact project dimensions, including custom bearing bar sizes, spacing, and overall panel size, ensuring your installation fits perfectly and performs reliably.

2. Optimal Load-Bearing Solutions

Unsure which steel grating can safely handle your load requirements? Hengchen’s engineers analyze your project conditions and recommend the right bearing bar type, spacing, and material to ensure maximum safety and durability while minimizing material costs.

3. Corrosion and Environmental Protection

Projects in outdoor or corrosive environments often suffer premature wear. Hengchen offers hot-dip galvanized, stainless steel, and powder-coated grating options designed to withstand harsh weather, chemical exposure, or high-moisture areas, extending service life and reducing maintenance costs.

4. Installation and Maintenance Efficiency

Time-consuming installation and high maintenance are common problems in industrial settings. Hengchen provides pre-fabricated and easy-to-install steel grating, with optional serrated surfaces for anti-slip safety, helping you save time, labor, and ongoing maintenance efforts.

5. Expert Guidance and Support

Selecting the right steel grating can be complicated, from material choice to compliance with international standards. Hengchen’s team offers professional technical support, including load calculation, material selection, and custom design advice, ensuring your project is optimized for performance and cost.

With Hengchen, you’re not just buying steel grating – you're getting a partner who solves your industrial access, safety, and drainage challenges efficiently.
