Understanding Swaged Grating Fundamentals

Modern industrial projects require swaged grating
solutions that combine structural integrity with material efficiency. Unlike traditional expanded grating, the swaging process cold-works metal sheets to create interlocked bearing bars and cross rods, achieving 22% higher tensile strength according to ASTM A123 standards. This manufacturing method enables:

40% weight reduction compared to conventional steel grids
Superior slip resistance (COF ≥0.85 in wet conditions)
Customizable openings from 15mm to 100mm

FAQS on swaged grating

Q: What is the key difference between swaged grating and expanded grating?

A: Swaged grating features interlocked metal bars pressed into a flat surface, offering high strength, while expanded grating is formed by cutting and stretching metal sheets, creating a lighter-weight mesh ideal for drainage and platforms.

Q: Where are swaged gratings commonly used?

A: Swaged gratings are widely used in industrial flooring, bridges, and stair treads due to their durability, slip resistance, and ability to handle heavy loads.

Q: What materials are typically used for expanded grating?

A: Expanded grating is usually made from stainless steel, aluminum, or carbon steel, providing corrosion resistance and versatility for applications like walkways and machinery guards.

Q: Why choose swaged grating over gully grating for heavy traffic areas?

A: Swaged grating offers superior load-bearing capacity and structural stability compared to gully grating, which is designed primarily for water drainage in urban or landscape settings.

Q: What factors determine gully grating selection in drainage systems?

A: Key factors include anticipated water flow volume, corrosion resistance requirements (e.g., polymer vs. galvanized steel), and compliance with local safety standards for pedestrian or vehicular use.
