Powder Coat Finishes
Hundreds of coatings are available from such recognized names as Dupont, Morton and Sherwin Williams. Powder coat is spray-applied electrostatically to grounded skylight frames. Powder particles remain in an excited state within the electrical field, contributing to a consistent coating thickness free of drips, runs or sags that can occur with liquids, so rejection rates for finish quality are low. Convection ovens melt the powder particles adhering to the aluminum frame, fusing them. This is a advantage compared to liquid applied paints and anodizing. Our ovens are large enough to fit a whole car in them!! This enables GSI, in most cases, to paint the whole skylight after fabrication. This means there will be no exposed welds or fabrication marks on the finished product.

Powder Coat Advantages
QUALITY: The unique rheological and application characteristics of powder coatings provide superior consistency and uniformity of finish without sags, drips, runs, or bubbles. They provide extremely tough, durable films, enhancing the high quality, value-added image of consumer products. In general, the performance properties, such as impact resistance, flexibility, and corrosion resistance of powder coatings are better than liquid paints. Powder coated parts resist cracking, peeling, and marring during handling and normal service use. In many cases, merchandise is specifically being advertised as "POWDER COATED" because of the quality image it projects

ECONOMICS: Powder coatings are frequently a cost saving alternative to liquid paints with respect to energy savings, labor costs, rework costs, material usage, waste disposal, and overall line efficiency. The advantage to manufacturers and the consumers is a coated part with a superior quality finish at a reasonable cost. 

ENVIRONMENTAL: Environmental issues are of significant interest and importance to the government and general public today. Unlike many liquid paints, powder coatings are compliant with environmental regulations. Liquid paints often contain solvents, which can contribute to air pollution and, in some cases, ozone depletion. Powder coatings are free of such pollutants. Wet painting processes can generate sludge, which must be disposed of into hazardous waste landfills. Properly formulated powder coatings generate no such hazardous waste. The consumer can feel good about buying a powder-coated product, which is ENVIRONMENTALLY RESPONSIBLE.
