General Introduction to Galvanized Steel Grating
Galvanized Steel Grating is a strong, durable, and cost-effective flooring and covering solution made from mild steel bearing bars and cross bars welded or press-locked into a grid structure. After fabrication, the surface is treated by hot-dip galvanizing or electro-galvanizing, forming a protective zinc coating that provides excellent corrosion resistance and extends the service life even in harsh industrial or outdoor environments.
With high load-bearing capacity, slip resistance, and easy installation, galvanized steel grating is widely applied in industrial platforms, walkways, trench covers, drainage systems, stair treads, and municipal construction projects. Its combination of safety, strength, and cost-efficiency makes it a preferred choice in both new constructions and renovation works.
Types And Specification of Galvanized Steel Grating
Types of Galvanized Steel Grating
Hot-Dip Galvanized Steel Grating
Immersed in molten zinc, forming a thick and firmly bonded zinc-iron alloy layer. This provides superior anti-corrosion performance, strong adhesion, and long service life. Commonly used in chemical plants, power stations, water treatment facilities, and outdoor projects.
Press-Locked Galvanized Steel Grating
Manufactured by press-locking cross bars into bearing bars without welding. It features p
recise spacing, a clean appearance, high strength, and light weight. Suitable for architectural applications, pedestrian walkways, shipyards, and mechanical platforms.
Welded Galvanized Steel Grating
Produced by welding flat bars or I-bars with cross rods, then galvanized. Known for high load-bearing capacity and wide applicability in construction, petrochemical, sewage treatment, and food processing industries.

Hengchen's Inspection of Zinc Coating
Manufacturing Process
Surface Pre-Treatment – Rust, oil, and scale are removed by shot blasting or acid cleaning.
Pickling – Oxide layers are dissolved using hydrochloric acid for a clean metal surface.
Fluxing – Zinc chloride solution ensures better adhesion and corrosion protection.
Hot-Dip Galvanizing – Gratings are immersed in molten zinc to form a durable zinc-iron alloy layer.
Cooling – Solidifies the protective coating, available in air-cooled or water-cooled methods.
Passivation (Optional) – Provides additional resistance to surface oxidation.
Packaging – Carefully wrapped with plastic film and secured in crates to ensure protection during transport.
Package and Ship
For secure transportation, we offer the following packaging options:
Strap Packing: Ideal for small-sized press-locked grating.
Pallet Packing: Suitable for large orders and container loading.
Screw Rod Fixation: Secures the grating in place for safe transit.
Our products are carefully inspected and packaged to meet international shipping standards.
