Powder Coating

Powder coating is an attractive alternative to painted finishes.  It is a high quality finish that protects against rust, corrosion, and the elements, and provides a smooth and consistent appearance.  Powder coating is an extremely scratch resistant finish that will last practically forever!

Powder coating is an environmentally friendly color-solution as it is virtually free from pollutants. Unlike liquid paint, there are no solvents in the process and only negligible amounts of volatile organic compounds (VOCs) are released in the air. The unused or overspray ground particles of pigment and resin are collected and reused in other batches to keep it out of landfills.

Also, Rainier is an ISO-14001 certified company, the premier certification in environmental stewardship, and ISO-9001 for our Quality Management System.  When you choose Rainier for your powder coating needs, you know it will be earth friendly, turned on time and on spec.

The process starts with cleaning the material in the large wash booth to eliminate all dirt, grime or oils that may have accumulated during the manufacturing process. We then move the product to the oven and crank it up to 2,100,000 BTUs to eliminate moisture and ensure an even coating of powder in the next step. The powder coat particles are electrostatically charged and sprayed onto the parts that are positively grounded. The coated product then goes into a giant oven, where it is baked at 400 degrees for 15 to 40 minutes, depending on the material.  The product then is returned to production for final assembly or carefully packaged for shipping or will call. We can deliver in the greater Seattle area for an additional fee.

Rainier has ten standard colors in stock, and can obtain and powder coat any standard RAL color within a day or two. Custom color matching is also available if needed. Our oven, wash booth and powder booth are 10’ wide x 10’ tall x 25’ long for handling single large pieces to hundreds of smaller parts. Size restrictions vary depending on diameter of parts or materials. Please contact us for more information regarding availability, pricing and size limitations.
