Galvanized High-Safety Steel Grating for Flooring Drainage Systems
Product Overview
Steel grating is manufactured from high-quality carbon steel or stainless steel, featuring flat steel arranged crosswise at specific intervals with cross bars, welded into a grid pattern with square openings. The exterior is typically hot-dip galvanized for superior corrosion resistance.
Hot-dip galvanizing: Applied after hemming completion, providing high corrosion resistance and significantly extending service life.
Painting: Spraying, painting, or dipping treatments available according to specific customer requirements.
Installation Methods
Welding: For permanent installations requiring no disassembly. Each corner requires a fillet weld with minimum 20mm length and 3mm height on the first flat steel.
Installation clamps: Preserves zinc layer and allows easy disassembly. Minimum 4 clamps per plate, with additional clamps required for longer plates.
Custom specifications available according to your requirements.
Classification by Spacing & Application
30mm Spacing (Common Type): Meets US standards with strongest surface impact resistance. Ideal for drain covers, stair treads in power plants, wastewater treatment plants, chemical plants, airports, and docks.
40mm Spacing (Economical & Lightweight): Complies with British standards for walkways and stairs. Perfect for small spans, warehouse shelves, trestles, and protective fences.
60mm Spacing (Mining Industry): Specifically developed for mining applications. Allows mineral splashes to pass through, maintaining clean and safe surfaces. Used in conveyor line walkways and processing plants.
Additional Classification Methods
By Welding Method: Pressure welding, inlaying, locking, and through welding types
By Bearing Bar Shape: Plane type, tooth type, and "I" type
By Material: Stainless steel grating and carbon steel grating
Applications
Steel gratings are renowned for their high strength and durability, serving critical roles across multiple industries:
Municipal engineering: Bridge guardrails and drainage ditch covers
Industrial facilities: Factory platforms and petrochemical plant equipment supports
Architectural decoration: Stair treads and light wells
Widely used in industrial platforms, stair treads, and other applications requiring load-bearing capacity, anti-slip properties, and drainage functionality - offering both performance and cost-effectiveness.
Frequently Asked Questions
How long does galvanized steel grating last?
Typically 15-30 years depending on environment and maintenance.
Is steel grating fire-resistant?
Yes, steel grating is non-combustible and suitable for high-temperature applications.
What is the standard size of steel grating panels?
Standard panels are 1m x 6m or 1.2m x 6m, but custom sizes are common.
How thick is steel grating?
Thickness varies from 25mm to 50mm or more, depending on load requirements.
