Product Description

Factory Hot-DIP Galvanized Stainless Steel and Iron Grating for Outdoor Exterior Stair Treads

Galvanized platform steel grating is a durable flooring system constructed from interconnected steel bars forming a grid pattern. Through hot-dip galvanization, these gratings receive a protective zinc coating that prevents rust and corrosion, making them ideal for environments exposed to moisture, chemicals, and outdoor elements.

Dimensions & Customization

Our steel gratings are typically rectangular and can be customized to your specific requirements. Common length specifications include 1000mm and 1200mm, with widths available in 300mm, 400mm, 500mm, and other sizes. The flat steel thickness ranges from 3mm to 10mm, while crossbar diameters measure between 3mm and 8mm.

Weight Specifications

The weight of steel grating varies based on size, material composition, and structural design. Stainless steel gratings are typically heavier than carbon steel equivalents. Denser grid patterns with thicker flat steel and crossbars also increase weight. Standard carbon steel platform step grating typically weighs between 30kg and 50kg per square meter.

Appearance & Construction

Our gratings feature flat steel and crossbars arranged and welded at precise intervals to create a uniform grid structure. The surface remains flat with securely welded intersections, free from burrs and defects. After hot-dip galvanizing, the surface exhibits a consistent silver-gray finish with a distinctive metallic luster.
