(3)Features:

1.Material 

1. )The material used in the excavator long arm is Q355B
2. )If other steel is required, please contact us, Q690D customized service

2.Material processing

Use a plasma cutter to ensure part flatness

3.Internal vie

Spaced by vertical and horizontal reinforcement plate at regular interval

4.Product making

 Welding
A.) Welded with mixed gas between argon and carbon dioxide. Argon content:80%.Carbon dioxide content:20%.
B.) Welded by auto-welding machine .
Sandblasting
A.) The surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, and prolonging the coating film. Durability, also good for paint leveling and decoration.
5.Product packaging and Shipping

6.Company Services
