Galvanized Metal Grating
Galvanized steel grating, also known as galvanized bar grating, is a grid-like metal sheet made of mild steel flat bars and twisted square bars welded horizontally and vertically. The surface of galvanized steel grating is treated with special hot-dipped galvanization, which has stable chemical and physical properties and is not easily corroded by air oxidation and microorganisms.Galvanized steel bar grating has strong impact resistance, strong corrosion resistance and heavy load-bearing capacity, beautiful and elegant, and has superior performance in municipal roadbed and steel platform construction projects.

Hot-dip Galvanized Steel Grating
Hot-dip galvanized steel grating is also known as hot-dip galvanizing, involves melting zinc ingots at high temperatures, putting in some auxiliary materials, and then dipping the structural metal parts into a galvanizing bath to attach a zinc layer to the metal parts.
Press-locked Galvanized Steel Grating
Press-locked Galvanized steel grating is made of low carbon steel and stainless steel. It is a grid formed by welding or press-locking cross bars to bearing bars. The press-locked grating has the characteristics of high strength, light structure, high bearing capacity, anti-corrosion and so on.It is widely used in power plants, chemical plants, oil refineries, steel mills, machinery factories, shipyards, paper mills and other industries.
Welded Galvanized Steel Grating
Welded Galvanized steel grating is made of low carbon steel or stainless steel. It is widely used in construction, petroleum, chemical industry, power plant, sewage treatment plant, food processing plants and other industries.The surface of the Welded Galvanized steel grating is hot dip galvanized or electro-galvanized
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.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
Heavy Duty Galvanized Steel Grating
Heavy Duty Steel Grating is manufactured by cross plain steel strips with the joint spot welded, 2mm thickness of steel strips as bearing and cross bars, then it is hot dip Zinc galvanized. This method provides a positive fusion of cross and bearing bars.
Different bearing bar thickness can be specified, the most common 1.8mm, 2.0mm with 30mm width and 10mm width.
Different thickness is offered to accommodate any load rating requirements. Universally used in most general industrial plants as well as commercial buildings; it has a wide range of uses such as walkways, platforms, safety barriers, ventilation grates, and drainage covers
Pressure Locked 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.
Swaged Rectangular Aluminum Grating
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
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.
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".
Aluminum Grating Walkway
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.
