Our outdoor furniture is covered in a copolymer-based thermoplastic powder coating. Thermoplastic is environmentally safe. The coating will not fade, crack, peel, warp, or discolor for the life of the product. Thermoplastic has the best adhesion rate of any other process. This keeps the metal base free of any corrosion possibilities. Thermoplastic is applied at a thickness of 25-30 mils. This allows maximum protection with the best possible surface. Thermoplastic can be easily repaired. Cuts are repaired by heating the affected area with an industrial heat gun. The thermoplastic will melt and rebind itself. The properties of thermoplastic also make spray painting difficult for vandals. Simply wash product with a standard industrial cleaner.
