1.Product parameters
 

2.Normal Procedure

one)cutting  
use the plasma chopping device minimize the metal to little components use for ideal welding and splicing
 
2)welding  
soon after steel reducing procedure the next action is welding .this approach the major perform is beam welding .the leading plate-bottom plate and the
middle  plate  will  be welding jointly .  this approach will be use submerged arc welding process.this kind of welding is quite
unique .its exclusively utilised in I beam welding .following this welding procedure other components of the trailer will be use distinct welding way
for different metal-argon arc welding-electric arc welding-handbook welding-gas welding and so on
 
three)blasting
this process is use for the first action of floor cleanness-tension aid-derusting prior to paiting .
 
4)electrophoresis coating  
this process use for much more detail floor cleanness
 
five)epoxy zinc primer spray coating 
this process is the long lasting a single prior to paiting .after this approach the trailer an be paiting
 
6)assembly
after all the method we have mationed .the previous procedure of the trailer is assembly.this process all the areas will be assemly .it including tire-wheel rim-king pin-landing gear-suspension-spring leaf -brake chamber-air wiring-electric power wiring-brake program and so on

seven)packing 
The final procedure is packing .all the trailer use different packing way as JCPTer requirment.soon after packing the trailer can be on the way to the JCPTer
