Aluminum Grating Types & Construction
Swage-Locked Aluminum Grating
Bearing bars and cross bars are assembled and locked by a swaging press. No welding, no rivets. Suitable for walkways, platforms and general industrial flooring.
Press-Locked Aluminum Grating
Bearing bars and cross bars are locked by high pressure without swaging. Provides a smooth, tight surface with high rigidity, suitable for architectural and visible applications.
Riveted Aluminum Grating
Cross bars are riveted to bearing bars. Suitable for heavy-duty platforms and where additional connection strength is required.
Aluminum Grating Ceiling
Linear aluminum grating used as open-cell suspended ceiling, sunshade and decorative screen for architectural projects.
Applications
Walkway & Platform
Walkways, operating platforms, catwalk flooring, inspection platforms.
Stair Treads & Ladders
Stair treads, ladder rungs, safety steps.
Trench & Drainage Cover
Trench covers, drainage grates, sump covers.
Architectural & Decorative
Suspended ceilings, sunshades, facades, decorative screens.

FAQ
Aluminum Grating — FAQ
Q: What is aluminum grating?
Aluminum grating is a load-bearing panel made from aluminum bearing bars and cross bars, locked together by swaging, pressing or riveting. It is used for walkways, platforms, stair treads and trench covers.
Q: What is the difference between aluminum grating and steel grating?
Aluminum grating is lighter and naturally corrosion-resistant, making it suitable for coastal, marine and lightweight platform applications. Steel grating has higher strength and lower material cost, but requires galvanizing or painting for corrosion protection.
Q: What bearing bar height and pitch can you manufacture?
We produce bearing bar heights from 20 mm to 100 mm, thickness from 2 mm to 10 mm, and bearing bar pitch of 20 / 30 / 40 / 60 mm.
Q: Can you produce custom panel sizes?
Yes. Panels up to 1200 × 3600 mm are available. Custom cutting, notching and edge banding can be produced against your drawing.
Q: What surface finishes are available?
Mill finish, anodizing and powder coating. Anodizing is recommended for exterior and coastal applications.
Q: What is the typical lead time?
Standard panels ship in 7–15 days. Custom sizes and surface finishes typically require 15–25 days depending on quantity.
