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.
Standard steel bar grating has the 1-3/16" and 15/16" bearing bar spacing. There is a type of steel bar grating, which has closer bearing bar spacing for heavy duty and special requirements applications, that is close mesh steel grating. Compared with standard steel bar grating, close mesh steel bar grating has higher load capacity and can be used in more applications. The closer spacing can permit the wheeled equipment passing, including the baby carriage, roller skates. Additional, the close mesh steel grating is suitable for the ADA (American Disability Act) standard. It can allow the wheel chairs get through fluently.

Plain steel grating, also called smooth surface grating, is a type of grating made of plain steel bars. The smooth surface contrast with serrated steel grating, which has a serrated surface. plain steel grating is the most widely used grating type, which is used in almost all of the applications. Plain steel grating can be made of carbon steel bar, aluminum steel bars and stainless steel bars. Cross bars of plain steel grating can be crimped bars, which are known as riveted steel gratings, flat square bars which are the press-locked gratings. The round bars is welded to the bearing bar is welded steel grating and the bars are placed into the pre-holes on the bearing bars to form the swage-locked grating. Classification of plain steel grating Plain steel grating can be divided into different types according to different standard. You can refer to the following classification and find the perfect product for you. And if you have other special requirements, just contact us for customization. Different fabrications Welded plain steel grating. The twisted square cross bars is welded onto bearing bars to form a firm and integrated structure. Swage-locked plain steel grating. The round or square bars is placed into pre-holes on the bearing bars and then locked by high pressure. Press-locked plain steel grating. The flat square bars is pressed onto the bearing bars by extremely high pressure. Sometimes, there are notches on bearing bars and cross bars. And the height of bearing bar and cross bar can be different.
Steel bar grating has two surface type: serrated surface and smooth surface. Serrated steel grating is made of serrated steel bars, which can be low carbon steel bars, aluminum steel bars and stainless steel bars. The serrated steel bars are welded, press-locked, swage-locked or connected by rivets to form different types of steel grating. Compared to the plain steel grating, which is available for almost all of the applications, the serrated steel grating is widely used in the wet, slippy places, which need anti-slip performance.
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 is a widely used grating type. It can be used in the trench and drainage system as the trench and drainage cover to ensure the excellent drainage performance and secure the pedestrians safety. Like most of steel gratings, such as welded steel grating and press-locked grating, the drainage trench grating is made of carbon steel, aluminum steel and stainless steel. Different materials of grating can suit different applications of customers. Carbon steel grating is the most economical grating among the three types and the aluminum grating features lightweight and corrosion resistance, it can be used in the corrosive environments. The stainless steel grating has unique chemical stability, it is the ideal products to be used in the acid or alkali environments and keep a long service life. Drainage trench grating types A galvanized drainage trench grate with angle frame on the white background. Angle frame can increase the load capacity of drainage trench grate. Trench grate and angle frame It is the simplest and most economical types of types of trench covers. It can be installed on the trench and drainage to form a cover. This cover can not only ensure the excellent drainage performance, but allow the traffic passing through. The galvanized angle frame gives the maximum opening and supplies a strong and solid base for the grating. It can bear the load of steel grating can improve the load carrying capacity of grating. Except for the standard trench grate, there is a type of grate is made of close mesh steel grating. The close mesh steel grating is available for pedestrians wearing high-heel shoes, bicycles and other wheeled equipment easy passing through. Angle sided grates Angle sided grate is a type of drainage trench cover with angle bar on the two side of the grating. It is fit for the concrete trench, which is molded a channel to place the grates. The sided angle bars can bear the load capacity of the grating and ensure the long service life of the grate. The appropriate opening size can not only enable the drainage but also block the large wastes from entering the trench and blocking the trench. The angle sided grate has smooth and serrated surface for choice. And the common length of angle sided grates are 1m. A galvanized angle sided grate with smooth surface.

The frame make it easy to install the box grating onto ground. There are hinges connecting the grate and frame. This design is ideal for easy cleaning of trench. The surface of box grate can be smooth and serrated to suit different applications of customers. The grate on the frame is mostly welded steel grating which is the simplest and most widely used grating type.
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.
