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.

Steel bar grating has so many applications. The platform and walkway application is one of the most important applications. Platform and walkway grating is widely used in the factories, walking street, parking lot, port, warehouse and other places to form a flat and open operating platform or walkway. Sometimes, the platform and walkway grating can be used combined with stair tread gratings for further application. The main types of platform and walkway grating are welded steel grating, swage-locked grating, press-locked grating, riveted grating and close mesh grating. Welded steel grating is the most commonly used type, it is suitable for all common applications. The swage-locked grating and press-locked grating supply excellent lateral stiffness of the grating. The riveted grating and close mesh grating are suitable for pedestrians who wearing high-heel shoes, roller skates and wheeled equipment passing through. To suit the shapes of ground and equipment, there maybe need irregular steel grating in some places. A welded platform and walking grating on the white background.

The platform and walkway grating supplies a large open places for convenient operating and accessing. Easy to install. The steel grating is easy to install and doesn't need any special skills. It is much easier than the concrete grounds. Low maintenance cost. It is easy to maintain the platform and walkway grating and the cost is lower than other material platform and walkways. Various types. The welded, press-locked and so many other types of grating make it possible to suit more applications and satisfy customers' requirements. Durable and long service life. The main material of platform and walkway grating is galvanized steels, which is corrosion resistance and rust resistance, all these can ensure the long service life of grating. Widely used. The platform and walkway grating is widely used in so many places, such as port, parking lot, power plant, pedestrian street and other places.
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.
