Product Introduction
Spec Sheet

Basic Description

The industry-standard choice for durability and value,hot-dip galvanized steel grating is built to last. Fabricated from load-bearing steel bars and welded into a rigid grid,the entire assembly is then immersed in molten zinc. This process creates a metallurgically bonded coating that protects against rust,even at cut edges,providing long-term service in demanding environments. Its high open area ensures excellent drainage and light transmission,making it ideal for a vast range of structural and safety applications.

Core Strengths

Proven Corrosion Protection:

The hot-dip galvanizing process provides a thick,durable zinc barrier that offers superior rust resistance compared to painting,significantly extending service life outdoors and in damp conditions.

High Strength & Load Capacity:

The welded steel construction delivers exceptional strength-to-weight ratio,safely supporting heavy foot traffic,equipment,and vehicular loads on platforms and walkways.

Maximum Open Area & Safety:

The design allows for excellent air,light,and fluid passage while providing a secure,slip-resistant walking surface,even when wet or oily.

Low Lifetime Cost & Excellent Value:

Delivers the durability and performance of steel at a more accessible price point than stainless steel,offering outstanding long-term return on investment with minimal maintenance.

Fire Resistance & Non-Combustibility:

Steel is inherently non-combustible,making this grating a safe choice for areas with strict fire codes or near high-heat sources.

Versatile & Widely Available:

As an industry staple,it is readily available in numerous standard sizes and can be easily customized,fabricated,and installed using common methods.

Installation and Maintenance

Installation
  • Can be installed by welding to supporting steel structures,or secured with bolted clips and fasteners for removable panels. Always handle with care to avoid damaging the zinc coating at lifting points.
Maintenance
  • Requires minimal maintenance. Periodically wash with water to remove dirt and corrosive salts. Inspect for any significant mechanical damage to the zinc coating; small scratches are typically protected by the surrounding zinc. Avoid exposure to strong acids or alkalis that can attack the coating.
