pallet rack powder coating plant

Powder coating is a durable and protective surface treatment that has become ubiquitous in pallet rack or strorage shelves.

In electrostatic powder coatingprocess, a specialized spray gun applies electrically charged powder to grounded metal parts. The sprayed parts are then placed in a curing oven, where the coating chemically reacts with heat to form long molecular coverage film with high cross-link density, making it tougher and than paint.

Unlike paint, powder coating does not rely on a liquid solvent, without emiting dangerous volatile organic compounds, environmental friendly and heathy for workers.

As a 10 years manufacturer of powder coating equipment and system, we happen to many customers seeking automatic powder coating solution for pallet, thus we have design, produce and install a variety of plant for aluminum profile factories.
