1.Merchandise parameters
 

2.Normal Procedure

1)cutting  
use the plasma reducing machine lower the metal to minor elements use for ideal welding and splicing
 
two)welding  
right after steel cutting method the subsequent action is welding .this approach the principal function is beam welding .the prime plate-base plate and the
middle  plate  will  be welding with each other .  this method will be use submerged arc welding method.this kind of welding is extremely
particular .its solely utilized in I beam welding .following this welding approach other areas of the trailer will be use different welding way
for various steel-argon arc welding-electric powered arc welding-manual welding-fuel welding and so on
 
three)blasting
this approach is use for the initial step of surface area cleanness-tension aid-derusting before paiting .
 
4)electrophoresis coating  
this procedure use for much more detail area cleanness
 
five)epoxy zinc primer spray coating 
this process is the long lasting one particular before paiting .following this approach the trailer an be paiting
 
6)assembly
soon after all the process we have mationed .the final process of the trailer is assembly.this approach all the elements will be assemly .it like tire-wheel rim-king pin-landing equipment-suspension-spring leaf -brake chamber-air wiring-electric power wiring-brake method and so on

seven)packing 
The final method is packing .all the trailer use various packing way as JCPTer requirment.right after packing the trailer can be on the way to the JCPTer
