Steel gratings are widely used in industrial flooring, walkways, stair treads, trench covers, platforms, and even in marine and municipal projects. Choosing the right type of grating—and more importantly, the right manufacturer—is key to making sure your project is safe, cost-effective, and built to last.
As a professional steel grating manufacturer based in China, Hengchen provides high-quality products with strong customization capabilities and export experience. This article explains different types of steel gratings, their advantages, how to maintain them, and why more and more buyers are choosing Hengchen as their long-term partner.
Types of Steel Grating
1.Classification by Manufacturing Process
Type | Advantages | Disadvantages | Best Use |
Welded Grating | Strong load capacity, affordable, fast production | Weld points may corrode over time, harder to remove | Heavy-duty platforms, industrial flooring |
Press-Locked Grating | Smooth surface, good for appearance, easy to install | Slightly higher cost, less load-bearing than welded type | Commercial or decorative uses |
Interlocked Grating | Easy to assemble/disassemble, no welding needed | Less stable, not for heavy loads | Temporary structures, exhibition floors |
✅ Hengchen owns automated welding and locking lines, capable of producing various types of gratings in custom sizes, including irregular shapes.
2. Classification by Material
Material | Benefits | Limitations |
Carbon Steel | Low cost, strong, suitable for most industries | Prone to rust if untreated |
Stainless Steel | Corrosion-resistant, clean appearance, long-lasting | Higher cost, lower strength than carbon steel |
Aluminum Alloy | Lightweight, corrosion-resistant, easy to handle | Less strength, not suitable for heavy loads |
At Hengchen, we use Q235, 304 stainless steel, 6061 aluminum, and other verified materials with full test reports available.
