Excell Aluminum Railings and Fences are Powder Coated! Powder coating is an advanced method of applying a decorative and protective finish. Powder coating is one of the most durable exterior finishes available today. It is used on many metal items that are exposed to the weather because, as a finish, it is the best way to insure durability, weather resistance, and color retention. The powder is a mixture of finely ground particles of pigment and resin, sprayed onto the surface to be coated. The charged powder particles adhere to the grounded surfaces until fused by heat into a uniform, durable, high quality, and attractive finish. End result: A superior finish in terms of corrosion, impact resistance, and aesthetics. What are the Benefits of Powdercoating? Environmental Compliance, Energy Savings, Manufacturing Efficiency, Corrosion Resistant Finish.

The Process

Material to be powder coated is washed in a 4-stage, cabinet-style (spray nozzles) ALKALINE Wash System. The pre-treatment cabinet is equipped with hundreds of nozzles set to ensure the entire surface of all components are completely clean and fee of contaminants (like dust, oil or grease) that may affect the finish. Our fourth stage "Seal Coat" process (E-CLPS), is a chrome free, non-phosphate liquid-coating chemical used to produce (on Aluminum and Zinc alloys) a clear, nearly colorless chemical called 'Dried-In-Place' (DIP). The coating, when applied, has excellent paint bonding properties and affords under-film protection.

The parts then travel through the pre-dry oven to ensure that they are dry and ready for the powder to be applied. Parts are checked and recorded after the wash system and the pre-dry oven to ensure that the systems are functioning properly.

Elements are inspected by personnel before entering the powder booth to make sure the parts are positioned correctly for the powder application. Parts can be masked off at this point if some areas must remain powder free.

The powder is electrostatically applied using manual guns, then baked in a convection oven at 400 degrees F.
