Surface Treatment

DUOLENG steel grit and steel shot are widelyused in surface treatment field.

Containers
Through use steel grits can improve the production efficiency for containers,and help create a moderately rough container surface, thus ensuring bettercoating quality.

Petroleum and natural gas pipeline
After given grit blasting and anti-corrosion treatment, the pipeline comeswith superior resistance to corrosions from natural environment.

Vehicle body
After grit blasting, vehicle bodies can have better painting and coatingquality.

Surface pre-treatment and casting
Steel grit can also be used in metal surface treatment and casting surfacecleanness and oxide layer removal. 

Roller
Special treated steel girt can help ensure the performance and roughness ofthe rollers.

Engineering machinery
Steel grits can be used to remove the oxide layer for engineering equipmentbody part, and this can greatly improve equipment coating’s rust resistance.

Bridge and steel structure
Our steel grit and steel shot can be used in surface treatment and oxidelayer removal for bridges and steel structures, and this can improve thecoating’s corrosion resistance greatly.

Aviation
In aviation industry, steel grit and steel shot can be used for metalsurface toughening treatment so as to extend materials’ service life.

Stainless steel 
DUOLENG steel grit and steel shot are ideal for use in surface treatmentand dephosphorization treatment for stainless steel products.
