In order to avoid corroding and effectively extend the service life of the punching parts, galvanized steel
sheet with different specifications is widely adopted on the body (Figure 5-23).

1 Take measures on the structure of the body
a. Reasonably layout reinforcing ribs to improve the rigidity of parts and to reduce noise by restraining
vibration.
b. Fill the floor joint seam with sealant to strengthen the floor sealing and weaken the noise.
c. Increasing the thickness of the cowl is very effective to insulate sound. The cowl is adopted
sandwich structure, (Figure 5-24) that is, the cowl is welded by two steel plates (Cowl and heat
insulating board), and in the interlayer of the 2 plates lies a heat insulating pad (the material of it is
asphalt piece).
