China Metal Grating bar aluminum Grating for walkway Manufacturer and Supplier | Ruiyi

Metal grating is a metal product produced by perforating metal sheets or joining bars of metal to form a grid. This product is widely used in various industries as stairs, platforms, scaffolding, and protective coverings.

Steel grating, also known as bar grating or metal grating, is an open grid assembly of metal bars, in which the bearing bars, running in one direction, are spaced by rigid attachment to cross bars running perpendicular to them or by bent connecting bars extending between them, which is designed to hold heavy loads with minimal weight. It is widely used as floors, mezzanines, stair treads, fencing, trench covers and maintenance platforms in factories, workshops, motor rooms, trolley channels, heavy loading areas, boiler equipment and heavy equipment areas, etc

Aluminum grating bar is lightweight, corrosion resistant, and fully recyclable. these products are ideal for both industrial and architectural applications. Manufactured from ASTM B221, 6063 or 6061 alloy or other steel materials.

Aluminum Bar Grating, also known as Swagged Aluminum Bar Grate, is light weight, yet strong and durable for all load bearing applications that need high corrosion resistance.

Aluminum grating bar is available in a variety of bearing bar spacing, thicknesses and heights depending on applications and load requirements. Available in either smooth top or serrated for added slip resistance.

How to produce aluminum grating bar?

Arrange a plurality of punched aluminum strips ( load bar) at a certain distance, insert the aluminum square rod ( Cross Rod) into the arrranged load bar holes, press the part of the cross rod between the load bars to expand, tighten and fix the load bars, and form a grating plate together with the cross rods.

The load bar can be rectangular, I-shaped and T-shaped. 6061 and 6063- T6 aluminum alloy is the most commonly used materials for aluminum grating.

Aluminum grating bar 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 bar has great versatile and durable and is mainly used for platform ceilings and outdoor curtain walls.

Aluminum grating bar is made of aluminum alloy featured by cheap, economical and practical.  It is lighter than steel grating and has high load carrying capacity.

Aluminum Grating bar is kinds of Smooth and serrated surfaces with 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.

Cross bars as one of main part of aluminum grating bar 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.

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.

Specification for some aluminum grating bar

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″.

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.

Specification
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″.

Aluminum grating bar is an ideal choice when corrosion-resistant, lightweight materials that do not affect its load capacity and mechanical strength is required.

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.
