Powder coating is a finishing technology where a uniform, attractive, and extremely durable coating can be applied to a wide range of products. The process involves spraying finely ground, electrostatically charged particles of pigment and resin onto a surface to be coated. The charged powder particles adhere to the electrically grounded surfaces. The materials used are free of Volatile Organic Compounds (VOC’s), making the process environmentally friendly. The coated parts are then placed into a curing oven for a specific time and at a specific temperature, depending on the type of metal being coated. Curing ovens can be powered by various heat transfer technologies, such as convection, infrared, or ultraviolet. Powder coating technology is replacing liquid finishing technologies because of its durability, ease of use, and uniform application, while also rewarding its users with cost savings versus conventional liquid coatings. It has become prevalent where extraordinary coating durability is valued. Over the last 20 years, it has become recognized as a superior process and is now widely used in various industrial finishing applications. For these reasons, powder coating is the most rapidly growing finishing technology in North America. 

Sand Blasting is a mixture of water, glass,sand or soda and Environmentally friendly additives to prevent flash rusting. It’s virtually dustless and ideal for all types of metal, cast, aluminum ‎brick and concrete.


The entire powder coating process involves several steps:

  • a blasting, stripping and/or solvent cleaning step to insure the substrate is free of any oils, dirt, rust, mill scale, etc; 

  • a pretreatment step (an important step not done by all coaters) during which the product is treated with a pretreatment chemical or conversion coating, usually phosphate or zinc based, to further protect it and improve the surface for powder adherence; 
  • rinse, rinse, rinse…dry completely then; 

  • powder coat, usually done with an electrostatic gun, but sometimes in a fluidized bed; 
finally, FULLY cure the powder in the oven, generally at 375-400 deg. F, 15-20 minutes (varies) , making sure the oven is preheated to temp.
