Features of Aluminum Bar Grating
Aluminum bar grating is an essential component in many industrial and architectural applications due to its light weight, high strength and corrosion resistance. The main types of aluminum bar grating include plain locking rectangular aluminum grating, forged I-bar aluminum grating, forged flat top aluminum grating, dovetail press lock aluminum grating and expanded mesh aluminum grating, each type has specific features suitable for various requirements and environments.
Rectangular Swaged Aluminum Bar Gratings
Rectangular swaged aluminum grating is known for its clean and sharp lines, making it a popular choice for public places that are both aesthetically pleasing and practical. The cross bars are completely swaged into the bearing bars and slightly lower than the top surface, providing nearly 80% open area for easy passage of dirt, debris, snow and liquids. For applications that require a non-slip surface, a serrated walking surface can be provided upon request.
I-bar Swaged Aluminum Grating
I-bar swaged aluminum grating has a unique I-shaped bearing bar that provides an excellent strength-to-weight ratio. This type of grating is usually manufactured with a standard non-slip striped walking surface, ensuring safety in a variety of industrial applications. Like rectangular grating, it is lightweight and very durable, suitable for platforms, walkways and other load-bearing structures.
Pressed Locked Aluminum Grating
Pressed Locked Aluminum Grating is designed for applications that require a smooth top surface. This type of grating features load-bearing bars and cross bars that are flush with each other to form a uniform surface. It is often used in aesthetically pleasing and easy-to-move environments, such as architectural design and public facilities.
Dovetail Press-Lock Aluminum Grating
Dovetail Press-Lock Aluminum Grating is manufactured by inserting deep rectangular crossbars into pre-punched load-bearing bars to form an interlocking structure. This process ensures strong lateral stability and a neat appearance. The tight spacing of this grating type makes it ideal for sunshades, infill panels and other architectural applications that require a refined appearance and precise spacing.
Riveted Aluminum Grating
Riveted aluminum grating is particularly suitable for heavy-duty applications. Riveted aluminum grating has a greater load-bearing capacity than welded or press-locked grating of the same span and depth. Available in both steel and aluminum, Riveted Rod Grating is often used in industries that require high strength and durability, such as refineries, wastewater treatment plants and shipbuilding.
Fine Mesh Aluminum Grating
Fine Mesh Aluminum Grating is similar to standard grating, but with closer bearing bar spacing, ranging from 7/16″ to 13/16″. This configuration is ideal for applications where narrow spacing is required for aesthetic or functional reasons, such as ADA compliance. Fine Mesh Grating can be manufactured with welded, crimped, or crimp-lock construction types, providing versatility for a variety of applications.
Finishing Options of Aluminum Grating
Aluminum grating is typically available with a standard rolled finish. However, for architectural applications or highly corrosive environments, additional finishes such as anodizing, chemical cleaning, or powder coating can be provided. These finishes enhance the durability and appearance of the grating, making it suitable for a wider range of uses.
Custom Aluminum Bar Grating
We can assist customers in designing aluminum grating styles and providing design drawings according to the needs of different projects, and produce different grating shapes. At the same time, our welders will weld the cut edges according to welding specifications.
