Frequently Asked Questions (FAQ)
The key difference lies in the chemical composition and resulting corrosion resistance. Grade 304 stainless steel is the most common and is suitable for most environments, offering excellent corrosion resistance to atmospheric conditions. Grade 316 contains an added element, molybdenum, which significantly enhances its resistance to chlorides (like salt) and other harsh chemicals. Therefore, 316 is the mandatory choice for marine applications, coastal areas, chemical plants, and de-icing salt exposure.
"Pitch" refers to the center-to-center distance between the main load-bearing bars. It's a critical specification. A smaller pitch (e.g., 30mm) results in a stronger, more solid-feeling surface that is better for high-traffic pedestrian areas and can prevent smaller objects from falling through. A larger pitch (e.g., 40mm or 60mm) is more economical and lighter but offers less load capacity and a wider opening.
Load-bearing capabilities are determined through a combination of engineering calculations and physical testing, as outlined in ANSI/NAAMM MBG 531 standards. The capacity depends on the bearing bar height and thickness, the pitch, and the span (the distance between supports). We provide detailed load tables for all our products, showing allowable uniform and concentrated loads for various spans to ensure you select a grating that meets your project's safety requirements.
Absolutely. We specialize in custom fabrication. Using your DXF or DWG files, our facility uses CNC plasma or waterjet cutters to create grating panels in virtually any shape, including circles, rings, and complex multi-sided forms. All cut edges are banded with a flat bar of the same material to ensure structural integrity and a clean, safe edge.
Welded grating is made by forge-welding the cross bars to the bearing bars, creating an extremely strong, one-piece construction ideal for heavy-duty industrial applications. Press-locked grating is manufactured by notching both the bearing and cross bars and then pressing them together under high pressure. This method provides a very clean, architectural appearance with crisp intersections and excellent lateral stability, making it popular for architectural facades and public spaces.
The two main surface finishes are 'Plain' and 'Serrated'. Plain surface grating is smooth and suitable for most general-purpose walkways. Serrated surface grating has small notches cut into the top of the bearing bars, creating an aggressively anti-slip surface. It is highly recommended for any area prone to oil, grease, ice, or excessive moisture to significantly enhance worker safety.
Installation is typically done using specialized grating clips (saddle clips) that fasten the panel to the supporting steel structure. The number and type of clips depend on the load requirements. Maintenance for stainless steel net is minimal. Regular cleaning with water and a mild detergent is usually sufficient to maintain its appearance. In industrial environments, periodic washdowns to remove deposits will ensure the passive layer remains intact and the product's long life is achieved.
"The architectural trend towards industrial aesthetics has elevated materials like stainless steel grating from purely functional components to key design elements. Its combination of form, function, and longevity makes it a premier choice for modern building envelopes and public infrastructure."
