1.Product parameters
 

two.Normal Procedure

1)cutting  
use the plasma reducing machine reduce the metal to small elements use for appropriate welding and splicing
 
two)welding  
following steel cutting approach the following phase is welding .this procedure the principal operate is beam welding .the top plate-base plate and the
middle  plate  will  be welding together .  this method will be use submerged arc welding approach.this kind of welding is very
unique .its solely utilized in I beam welding .after this welding approach other elements of the trailer will be use diverse welding way
for different metal-argon arc welding-electric powered arc welding-guide welding-fuel welding and so on
 
three)blasting
this procedure is use for the very first stage of surface area cleanness-stress relief-derusting ahead of paiting .
 
4)electrophoresis coating  
this procedure use for much more detail floor cleanness
 
five)epoxy zinc primer spray coating 
this approach is the long lasting a single ahead of paiting .soon after this method the trailer an be paiting
 
6)assembly
right after all the method we have mationed .the previous treatment of the trailer is assembly.this approach all the areas will be assemly .it including tire-wheel rim-king pin-landing gear-suspension-spring leaf -brake chamber-air wiring-electrical power wiring-brake method and so on

7)packing 
The very last method is packing .all the trailer use diverse packing way as JCPTer requirment.after packing the trailer can be on the way to the JCPTer
