The GB852 standard refers to the Chinese national standard "Square taper washers for I section", which is a type of washer designed specifically for use with I-beams and is used in conjunction with bolts or screws to provide better load carrying capacity and to prevent fasteners from loosening.
Carbon Steel: Typically used for general applications.
Stainless Steel: For environments where corrosion resistance is required.
Alloy Steels: Used in applications requiring high strength or high temperature resistance.
Advantage:
Designed for I-beams: The design of this washer allows it to fit tightly into the cross-section of the I-beam, providing better support and load distribution. Square beveled design: The square beveled design helps to better fit the beveled surface of the I-beam during fastening and enhances the fastening effect. Multiple sizes: According to GB/T 852-1988 standard, the washers are available in multiple sizes to fit different sizes of I-beams. Material strength: usually made of carbon structural steel, such as A3 steel according to GB/T 700 standard, with good mechanical properties and strength.
Scope of Application
Building construction: In building construction, it is used to connect I-beam girders to other structural components, providing a stable and reliable connection. Bridge construction: In bridge construction, it is used to ensure the stability and safety of I-beams. Industrial machinery: in machine building, for fixing and adjusting I-beam frames and supporting structures.
