Expanded Metal Grating for Secure Walking Expanded metal grating is manufactured by piercing and stretching the metal sheet in one operation creating anti-slip surface with diamond openings. The anti-slip surface offers safe foothold to stand and walk, and the openings provides free passage for unwanted materials, also gives an aesthetic appeal for design. Expanded metal grating has thicker strands than normal expanded metal sheet, which in turn affords it large load bearing characteristics. Feature Diamond openings allow free passage of air, sound, heat and light. Superb strength to weight ratio. Tested load bearing capacities. Anti-slip properties suitable for applications where safety underfoot is critical. High corrosion and abrasion resistance. Cut to size service is available. Specification Material: stainless steel, aluminum, carbon steel, galvanized steel. Opening shapes: hexagon, diamond. Popular dimensions (cut to size service is available): Overall thickness: 0.2" - 0.87". Sheet size: 96" × 72", 96" × 48", 120" × 48". Open area: 48% - 77%. Note: when ordering expanded metal grating sheet, list the SW first, for example, 4' × 8', 6' × 8', and we also offer cut to size service. Standard flow expanded metal grating and reverse flow expanded metal grating There are two ways for expanded metal grating, SW is measured paralleled to the short way of the diamond opening.

Swage-locked grating, also called aluminum grating, is mainly made of aluminum steel bars, and other materials can be stainless steel bars. The bearing bars can be rectangular bars or I bars. I bar swage-locked grating is the most widely used type. In the same depth, I bar swage-locked grating can supply the same strength with the rectangular bar swage-locked grating, but it is lighter and cheaper than the rectangular bars swage-locked grating. The cross bars are inserted into pre-punched holes of bearing bars and then it is hydraulically swaged under tons of pressure to lock the bearing bars in place. In these processes, the swage-locked grating form a permanent locked structure. The standard bearing bar spacing is 1-3/16" or 15/16". There a type of new products named as close mesh steel grating, which has the closer spacing than the standard. The spacing of close mesh steel grating can range from 7/16" to 11/16".
Press-locked grating is also called pressure locked grating or press-locked steel bar grating. Basically, the press-locked grating have the same load capacity with the welded steel bar grating. The difference between press-locked grating and welded steel bar grating are joint connection technology and cross bars. Cross bars of welded steel bar grating are twisted square rods and the bearing bars are rectangular bars or I type bars. Both the bearing bars and cross bars of press-locked grating are rectangular bars. Compared to welded steel bar grating, which is produced through resistance-welding process, the press-locked grating is constructed with the two close-tolerance slotted bars bonded together by tremendous hydraulic pressure. This production can let press-locked grating be a permanent locking. Press-locked grating and swage-locked grating has excellent lateral stiffness, which can be used in some special applications. And the serrated surface is available for press-locked grating.
Stair tread steel grating is one of the most widely used application of steel bar grating. It can be installed in the factories or in the parks for the permanent or temporary using. Stair tread can be made of low carbon steel, aluminum steel and stainless steel gratings. The low carbon steel grating can be galvanized and painted for better corrosion resistance. Types of stair tread steel grating According to the different fabrications of stair treads grating, it can be divided into welded stair treads, press-locked stair treads, swage-locked stair treads and riveted stair treads. Among the four types, the welded grating stair tread is the most widely used type. It has firm structure and simple technology. The press-locked and swage-locked stair tread can supply better lateral stiffness than other types of gratings. And the riveted stair treads features higher load carrying capacity for longer service life. A welded steel grating stair tread with checker plate nosing.
