1.Product parameters
 

two.Normal Procedure

one)cutting  
use the plasma cutting equipment cut the metal to little elements use for appropriate welding and splicing
 
two)welding  
right after steel chopping process the subsequent phase is welding .this procedure the primary work is beam welding .the best plate-bottom plate and the
middle  plate  will  be welding with each other .  this procedure will be use submerged arc welding method.this type of welding is extremely
unique .its exclusively used in I beam welding .right after this welding process other elements of the trailer will be use various welding way
for various steel-argon arc welding-electric powered arc welding-handbook welding-gas welding and so on
 
3)blasting
this method is use for the 1st step of floor cleanness-tension relief-derusting prior to paiting .
 
four)electrophoresis coating  
this method use for far more element surface cleanness
 
5)epoxy zinc primer spray coating 
this process is the long lasting one particular just before paiting .right after this procedure the trailer an be paiting
 
six)assembly
right after all the process we have mationed .the final process of the trailer is assembly.this process all the areas will be assemly .it such as tire-wheel rim-king pin-landing equipment-suspension-spring leaf -brake chamber-air wiring-electricity wiring-brake program and so on

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