Steel grating is a type of grating made from steel bars or sheets that are joined together to form a grid-like structure. It is commonly used in industrial settings, such as factories, warehouses, and outdoor areas, due to its strength, durability, and ability to withstand heavy loads.
Steel grating is typically made from carbon steel or stainless steel, which provides high strength and corrosion resistance. The grating is available in various patterns, such as bar grating, expanded metal grating, and perforated metal grating, to suit different applications and load requirements.
Steel bar grating is one of our main grating products,also know as press weld steel bar grating.Due to the extremely strong and durable for all the bearing application,which become the most popular grating in the markets.The stability makes them have a much higher performance in the application.

Steel bar grating is available in a variety of bearing bar spacing,thicknesses and depth according to the applications and loading requirements.
They are also available in either smooth top or serrated for anti-slip.
1. Walkways and platforms: Steel grating is often used to create safe and secure walkways and platforms in industrial settings. It provides a non-slip surface and allows for drainage of liquids and debris.
2. Stair treads: Steel grating can be used as stair treads to provide safe and sturdy steps in industrial and commercial buildings.
3. Drainage covers: Steel grating is commonly used as covers for drains and manholes. It allows for the flow of water and prevents debris from entering the drainage system.
4. Fencing and barriers: Steel grating can be used as fencing or barriers in outdoor areas to provide security and prevent unauthorized access.
5. Shelving and storage racks: Steel grating can be used as shelves or storage racks in warehouses and factories
Galvanized steel bar grating is made from hot-dip galvanized steel, which provides excellent corrosion resistance and ensures long-lasting durability. It can withstand harsh outdoor conditions, including exposure to rain, snow, sunlight, and chemicals
Hot-dip galvanized grid, also known as hot-dip galvanized steel grating, is a grid-shaped building material made of low carbon steel flat steel and twisted square steel welded horizontally and vertically.
Aluminum grating bar is lightweight, corrosion resistant, and fully recyclable. With an unmatched strength-to-weight ratio, 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 Brating 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?
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 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.
Aluminum bar grating 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.
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.
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
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.
