Unfinished Cast IronWhen downspout boots are required to match with the color of the downspouts or an architectural element of the building, powder coating is an excellent option. Powder manufacturers commonly supply a standard group of colors known as RAL Colors which consists of about 200 unique color options. Powder coating is more environmentally friendly than liquid paint and offers a more durable finish as well.
The following is a description of the powder coating process applied to J.R. Hoe downspout boots:
All parts are media blasted and thoroughly desanded in preparation for powder coating. In the pretreatment process parts travel along an 825-foot overhead conveyor to an environmentally friendly five-stage automated wash system, providing alkaline cleaning, rinsing and next generation conversion coating. The parts then pass through two additional rinsing stations, and continue to a high air velocity dry off oven before entering the powder rooms. In the powder rooms, ITW Gema guns are used to coat the electrostatically charged parts at 2.5 to 3.0 mils. The coated parts then travel through a 20’ infrared oven and a 95’ gas convection oven to cure the powder and create a durable, protective painted finish. In-house quality testing is performed regularly using ASTM standards.
