Lightweight, High Load Capacity & Strength Aluminum Grating
Aluminum grating is an ideal choice when corrosion-resistant, lightweight materials that do not affect its load capacity and mechanical strength is required. Made of ASTM B221, 6063 or 6061 alloy, aluminum grating has great versatile and durable and is mainly used for platform ceilings and outdoor curtain walls.
❖It is lighter than steel grating and has high load carrying capacity.
❖Aluminum gratings are made of aluminum alloy featured by cheap, economical and practical.
❖Smooth and serrated surfaces are available. Good anti-slip performance for safety protection.
❖Excellent corrosion and rust resistance for durability.
❖A variety of specifications and styles are available to meet various application environments.

Surface Type
Aluminum grating are generally available in four types: swaged rectangular aluminum grating, swaged I-bar aluminum grating, swaged flush-top aluminum grating, and dovetail pressure locked aluminum grating.
Rectangular Aluminum Grating Swaged
Cross bars are fully locked within the bearing bars, slightly below the top surface. It has clean and crisp lines. With nearly 80% open area, it is commonly used in public areas and is the industry accepted standard for industrial applications. If anti-slip is required, swaged rectangular aluminum gratings with a serrated surface are available upon request.
- Bearing bar size: 1″ x 1/8″ to 2–1/2″ x 3/16″ with 1/4″ increments;
- Bearing bar spacing (center-to-center): 1–3/16″, 15/16″, 11/16″ and 7/16″;
- Cross bar spacing (center-to-center): 4″ or 2″.
Swaged I-Bar Aluminum Grating
Supported by I-shaped extruded bearing bars, swaged I-bar aluminum grating carries the same load as the swaged rectangular aluminum grating with lighter weight and less costs. In addition, the striations at the top and bottom surfaces of the I bar increase the friction and provide high slip resistance performance.
- Bearing bar size: 1″ x 1/4″ to 2–1/2″ x 1/4″ with 1/4″ increments;
- Bearing bar spacing (center-to-center): 1–3/16″, 15/16″, 11/16″ and 7/16″;
- cross bar spacing (center-to-center): 4″or 2″.
Swaged Flush-Top Aluminum Grating
Cross bars are permanently locked within the bearing bars to lock the pressure via unique extruded cross bars. Swaged flush-top aluminum grating provides an enhanced walking surface for areas subject to continuous pedestrian traffic. If anti-slip is required, we can provide swaged flush-top aluminum gratings with a serrated surface. It is mainly used for public areas.
- Bearing bar size: 1 x 1/8″ to 2–1/2″ x 3/16″ with 1/4″ increments;
- Bearing bar spacing (center-to-center): 1–3/16″, 15/16″, 11/16″ and 7/16″;
- Cross bar spacing (center-to-center): 4″or 2″.
Dovetail Pressure Locked Aluminum Grating
Dovetail pressure locked aluminum grating is manufactured by inserting deep rectangular cross bars into pre-punched bearing bars to form an interlocking structure with strong lateral stability. Its neat appearance and tight spacing make it popular in architectural designs and is commonly used as sun shades and infill panels.
- Bearing bar size: 1 x 1/8″ to 2–1/2″ x 3/16″ with 1/4″ increments;
- Bearing bar spacing (center-to-center): 1–3/16″, 15/16″, 11/16” and 7/16″;
- Cross bar spacing (center-to-center): 4″or 2″.
Product Application
Because of its light weight, corrosion resistance, and non-sparking, Aluminum gratings are widely used in indoor ceilings, outdoor curtain walls and other decorative applications due to its lightweight, excellent corrosion resistance and non-sparking properties. It is suitable for industrial applications where the strength-to-weight ratio is important, such as wastewater treatment plants. It is mainly used for safety protection and served as walkways, floors, platforms, stair treads, fences, etc.
