disadvantages being expensive, needs maintenance, condensation resulting in due drops and breaking/deforming on impact due to poor flexibility. UPVC on the other hand provide the flexibility by absorbing energy from impact. The mechanism of chemical attack on thermoplastics in general, and our UPVC sheets in particular, differs significantly from the mechanism of corrosion of metals. Corrosion of metals results in a gradual loss of surface material as a result of electrolytic action by the relevant chemicals. Chemical attack on UPVC sheet has negligible effect on physical properties due to its high chemical resistance. In electroplating or chemical industry CGI Sheet (Corrugated Galvanized Iron/Steel sheet) like all metals and materials will corrode, galvanizing will tear eventually, and this can occur more quickly in situations where it might be exposed to the acidic or alkaline actions frequently. Even as rain or salt water can do the damage over time so it won’t be a wise choice if you want the best roofing solution for your project. Our premium quality UPVC sheets come in a wide variety of colors and thicknesses. Colored UPVC are ideal for all types of structures and roofing. Whether you choose transparent, translucent, or opaque colors, there is no limit to what you can do with this versatile product.
