Quality Control Tests

Kolor Metal operating with ISO 9001:2008 Quality System Standards has ben executing his quality control test and analysis precisely and carefully. Quality control tests shown in below tables that applied for pre-painted / pre-coated metal.

* The total thickness of coating mentoined above has validity of standard two layer (primer + topcoat) system applications. In addition, there are some special lacquers and varnishes that can be applied as single layer. Also there are some three or four layer coating systems. These systems can show different coating thicknesses belonging to application requirements.
