SpectraShield® Powder Coating
SpectraShield® is an environmentally friendly, factory applied polyester powder coating option that adds aesthetic value and eliminates the need for field painting. Layered on top of our standard GalvaNex™ finish, the SpectraShield finish includes a zirconium pre-treatment followed by a baked-on polyester powder coating. SpectraShield's lasting finish can integrate seamlessly into the building's surrounding areas or make a colorful architectural statement.
For a more durable finish, consider upgrading to our SpectraShield Ultra powder coat finish. Ultra is an additional finish that can be applied on top of SpectraShield. It is a polyester-based, textured, wear-resistant clear coat that provides improved durability against deterioration and/or marring of the curtain during regular use.

Of note, grille curtains are not eligible for powder coating.
Our Quality, Our Line
We control every step of the SpectraShield process. Our production line is state-of-the-art, with an automated continuous conveyor, metal cleaning and preparation, automatic powder guns, and a curing oven. The line is tailored to our products, enhancing quality and field performance as well as reducing manufacturing lead times.
Outperforms Field-Applied Finishes
The SpectraShield process begins with an ASTM A653 galvanized based coating treated with dual process rinsing agents in preparation for chemical bonding. All SpectraShield components are prepped, powder coated and cured with an electrostatic application that assures uniform, total coverage and a smooth finish that is tough and durable Once the base coat is finished, there's a zirconium pre-treatment followed by baked-on polyester powder coat, minimum 2.5 mils (0.065 mm) cured film thickness; ASTM D-3363, pencil hardness: H or better.
SpectraShield outperforms field-applied coatings in color retention, corrosion resistance, chemical resistance, UV stability and abrasion resistance. We control color formulations electronically, which means that additional or replacement components will match previous shipments.
Factory-applied powder coating is cost effective and competitive with field-applied solvent-based coatings. Proper surface preparation in the field is difficult and costly. Surface preparation by a factory powder coating process produces a smoother, longer-lasting finish at controlled costs.
Powder contains no solvents and so emits no polluting volatile organic compounds into the atmosphere. We collect and recycle oversprayed powder.
SpectraShield powder coated finish is available in more than 180 standard RAL colors to match or enhance any project. In addition, custom colors are available. Extended lead time and additional cost may apply. Please contact us for custom requests.
- Additional cost may apply

- While powder coated finishes offer exceptional toughness and impact resistance plus superior resistance to abrasion and chipping (due to the use of higher molecular weight resin systems), all coiling doors, high cycling doors in particular, are subject to wear. Durability of the finish varies with the door's use, pattern and size. Finish is not subject to warranty. Matching touch-up paint is supplied from the factory
