Hangzhou Beili powder coating production line

Surface Treatment

Powder coating integrated with sheet metal production

Finish selection, line processing, appearance control, and application-specific testing for cabinets, enclosures, and fabricated components.

Integrated Finishing

Consistent coating starts before the powder is applied

Powder coating performance depends on substrate condition, pretreatment, film build, curing, geometry, and handling. Integrating fabrication and coating allows structure and finish requirements to be reviewed as one production route.

Finish specifications can define color, texture, gloss, coating thickness, appearance acceptance, adhesion, and corrosion testing based on the target application.

FAQ

Powder coating questions

Can you match a specified color and texture?

Color reference, texture, gloss, sample approval, and batch consistency requirements should be included with the drawing or finish specification.

Is 1,000-hour salt spray available for every coating?

Testing capability is available, but the appropriate duration depends on material, pretreatment, coating system, structure, and end-use standard. Requirements are confirmed before production.

Can printing be added after coating?

Yes. Silk screen printing can follow powder coating where product markings, labels, or interface graphics are required.
