Parts preparation
Finished painting

For metal coatings, the quality problem caused by foreign matter and rusting on the surface is very important, so we are pickling the surface rusting part on the
material to build the pickling line to secure the quality of the surface , and electrodeposition, liquid, and powder coating are performed.
STL Bancheon Factory secures competitiveness through ONE STOP of metal products considering design, production, quality, and logistics.
