Royal Steel Group specializes in the development, manufacturing, and export of high-quality steel and metal gratings for engineering contractors, distributors, and end users worldwide. Backed by mature production lines and rigorous quality control systems, we deliver both standard catalog items and custom-engineered solutions — all manufactured to full international compliance. Our gratings have been supplied to projects across North America, Europe, Southeast Asia, the Middle East, and Oceania, serving industrial, municipal, offshore, and architectural applications.
Primary Classifications of Steel Grating
Steel grating — also referred to as metal grating — is assembled from load-bearing bars and cross bars through either resistance welding or serrated press-locking. Our main product lines include:
Welded steel grating — the most widely used type, formed by resistance-welding cross bars onto bearing bars for strong, cost-effective performance.
Press-locked grating — cross bars are mechanically pressed into slotted bearing bars, creating a clean, smooth surface ideal for architectural and pedestrian settings.
Serrated anti-slip grating — bearing bars feature a serrated surface to enhance traction, recommended for oily, wet, or high-traffic walkways.
I-section grating — uses I-shaped bearing bars to achieve high strength-to-weight ratios, reducing material and shipping costs without sacrificing load capacity.
Composite grating — combines a steel grating base with a checkered-plate or fiberglass top surface, offering a solid, non-slip walking surface while retaining drainage.
Lightweight grating has gained strong favor among global buyers. Compared with traditional heavy-duty grating, it offers lower dead weight, easier transportation, and faster on-site installation — directly reducing logistics and construction costs for customers.
Industry Specifications and Export Standards
Compliance with unified technical regulations is a prerequisite for cross-border grating trade. Royal Steel Group holds all lightweight grating products for export to demanding, credible quality standards.
We manufacture steel grating to the most widely recognized global standards:
| Region | Standard |
| North America | ANSI/NAAMM |
| United Kingdom | BS 4592 |
| Europe | EN ISO 14122 |
| Australia | AS 1657 |
| China | YB/T 4001.1 |
ASTM A123 hot-dip galvanizing is applied as our primary surface treatment to maximize corrosion resistance. We also provide complete material test reports (MTRs), factory inspection certificates, and dimensional documentation to support customs clearance and third-party project acceptance.
Common Applications
Thanks to their strong load capacity, open-area ventilation, efficient drainage, and anti-slip performance, steel and metal gratings are used across a wide range of industries:
Industrial walkways and equipment platforms
Stair treads and mezzanine flooring
Trench drain covers and gutter grates
Offshore and marine engineering structures
Wastewater treatment plants and chemical processing facilities
Pedestrian platforms, building facade decoration, and temporary construction sites (medium- to light-loading scenarios)
Sourcing Guidance for International Buyers
Before placing an order, international buyers are encouraged to verify three key points: required load capacity, anti-slip grade, and local certification requirements. As a professional steel grating manufacturer, Royal Steel Group offers tailored solutions in a wide range of sizes, with customizable surface treatments and edge processing. You can rely on us to deliver steel and metal grating that meets your local standards — on spec, on time, and on budget.
