square flat washer DIN 434 are washers designed for U-sections (channels) with two beveled surfaces and two grooves in the bevels to provide additional support and protection to increase the stability and load carrying capacity of the member. These washers are typically used in conjunction with bolts and nuts to provide additional support and protection to reduce stress concentrations.
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 U-beams: The beveled design of the DIN 434 washer allows it to fit snugly into the beveled face of the U-beam, providing better support and load distribution.
Double groove design: The double groove design of the washers helps to secure the washers and prevent them from rotating, ensuring a stable connection.
Multiple materials: These washers may be made of different materials such as carbon steel, stainless steel (e.g. A2 and A4 material) to suit different corrosion resistance and strength requirements.
Surface treatment: The surface of the washers may be treated with zinc plating, environmentally friendly zinc plating (ZSM), hot dip galvanizing (HDG), etc. to improve corrosion and abrasion resistance.
Scope of Application
Steel construction: In steel construction, it is used to connect beams, columns and other structural components to provide a stable and reliable connection.
Bridge construction: In bridge construction, used to ensure the stability and safety of U-shaped steel girders.
Machinery Manufacturing: In machinery manufacturing, used to fix and adjust machine parts such as bearings, gears and motors.
Industrial equipment: In various industrial equipment, used to adjust and fix components to improve the operating efficiency and reliability of the equipment.
