Pressure Locked Welded Bar Grating | China Press Locked Bar Grating ExporterDescription
The Pressure Locked Bar Grating is popular for the manufacture of aluminum, stainless steel, and close mesh gratings. Cross bars are inserted into pre-punched holes in the bearing bars and hydraulically deformed to lock the bars in place.
Metal Bar Grating is the workhorse of the industrial flooring market and has served industry for decades.Strong and durable with an exceptional strength-to-weight ratio, metal bar grating can be easily fabricated to nearly any configuration.The high percentage of open area makes bar grating practically maintenance-free and all products are fully recyclable.
Welded bar grating is available in three popular materials; mild carbon steel, 6000 series aluminum, and 300 series stainless steels. Additionally, Grating Pacific has the capacity to produce gratings constructed with other specialty metal alloys.
Manufactured by assembling a series of equally spaced metal bars to connecting cross members,
high-intensity, light structure: the grid pressure firmly welded structure to a high capacity, light structure, easy loading and other characteristics of aesthetic appearance.
Durability: hot-dip zinc surface treatment so as to make it a good anti-corrosion capacity , Shiny surface appearance; ventilation, lighting, heat, explosion-proof, anti-skid of good-plot dirt.
Welded Bar Grating is widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on.
The open ends of the grating panels can be banded to provide additional transverse stiffness and a finished architectural appearance. This is achieved by welding a flat bar, similar in size to the bearing bars, to the cut ends of the grating. Trim banding should always be specified when gratings are designed to be removable. Banding can reduce impact stresses by transferring loads to adjacent bearing bars and should always be specified when the grating is subject to vehicular loads.
The excellent self-cleaning characteristics of plain surface grating make it suitable for the majority of applications. In the presence of fluids or materials that could cause the top surface of the grating to become wet or slippery, specification of the optional serrated surface should be considered. When serrated grating is specified, the bearing bar depth must be 1/4" greater than the sizes shown on the load tables to provide the equivalent strength of non-serrated gratings..
Steel grating is usually provided with one of three finishes, bare steel (no finish), painted with one coat of manufacturers red, black or silver paint, or hot dip galvanized in accordance with ASTM A-123. Aluminum products are commonly supplied mill finish but they are also available with optional chemically cleaned or anodized finishes. Due to discoloration that occurs during welding and fabrication, Stainless Steel grating products typically require secondary finishing
|Commercial cleaning, passivation or abrasive blasting can provide a uniform matte surface and a bright stainless finish can be provided by electro-polishing. All grating products can be provided with specialty finishes including enamel or epoxy paints or powder coating. When considering specialty finishes, consultation with the coating manufacturer is essential.|
