Wallshell strictly controlled spray coating environment enables Wallshell to achieve the top qualities of its finish coat. We constantly measure coating temperature, spraying pressure, curing time, particle size, color RGB precision, board density, and board pre-treatment, etc, to assure the qualities unattainable by any other alternative approaches. With more than 20 years of fiber cement pre-treatment and finish coating experience and technology, we pride our fiber cement coating as a top rank in the world, leveraging our selected source for coating raw materials, our standardized procedures, and our patented machinery and equipment. By complying with ISO9001 and ICC approved quality control methods, we ensure that Wallshell panel systems perform safer, cost less and take less time to build and to maintain, resulting in substantially reduced development risk.
