2.Normal Procedure

one)cutting  
use the plasma slicing equipment lower the steel to minor areas use for suitable welding and splicing
 
two)welding  
after steel chopping procedure the subsequent phase is welding .this method the principal function is beam welding .the leading plate-base plate and the
middle  plate  will  be welding collectively .  this process will be use submerged arc welding method.this kind of welding is really
unique .its completely utilised in I beam welding .after this welding process other components of the trailer will be use different welding way
for different steel-argon arc welding-electric powered arc welding-manual welding-gas welding and so on
 
3)blasting
this process is use for the very first action of floor cleanness-tension aid-derusting ahead of paiting .
 
4)electrophoresis coating  
this approach use for more element area cleanness
 
five)epoxy zinc primer spray coating 
this process is the long lasting one ahead of paiting .soon after this method the trailer an be paiting
 
six)assembly
soon after all the approach we have mationed .the very last method of the trailer is assembly.this process all the parts will be assemly .it including tire-wheel rim-king pin-landing equipment-suspension-spring leaf -brake chamber-air wiring-electric power wiring-brake technique and so on

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