one.Merchandise parameters
 

2.Normal Procedure

one)cutting  
use the plasma cutting equipment reduce the steel to little elements use for appropriate welding and splicing
 
2)welding  
soon after metal slicing procedure the next stage is welding .this method the main work is beam welding .the top plate-bottom plate and the
middle  plate  will  be welding with each other .  this method will be use submerged arc welding process.this kind of welding is extremely
particular .its solely used in I beam welding .right after this welding approach other areas of the trailer will be use distinct welding way
for distinct steel-argon arc welding-electric powered arc welding-manual welding-fuel welding and so on
 
3)blasting
this method is use for the very first action of floor cleanness-pressure relief-derusting before paiting .
 
four)electrophoresis coating  
this process use for a lot more depth floor cleanness
 
5)epoxy zinc primer spray coating 
this approach is the long lasting one particular prior to paiting .soon after this method the trailer an be paiting
 
six)assembly
right after all the process we have mationed .the final procedure of the trailer is assembly.this approach all the elements will be assemly .it such as tire-wheel rim-king pin-landing gear-suspension-spring leaf -brake chamber-air wiring-electric power wiring-brake program and so on

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