Design of UPVC Thin Corrugated Roofing Sheet for Indonesian Market

Corrugated roofing sheet from Unplasticized Polyvinyl Chloride (UPVC) material has good prospects in Indonesia. The advantage of UPVC material is corrosion resistant, lightweight, not easily broken and economic. This paper describes the design of thin corrugated roofing sheet from UPVC material. The design includes determining the shape of the roof profile and its strength as a roof structure. Flammability properties, tensile strength and modulus of elasticity of roofing material are obtained from flammability and tensile tests of the roof sample. Roof production is carried out using an extrusion injection molding machine in a manufacturing plant at Tangerang, Indonesia. The result of the design is a corrugated thin roofing sheet from UPVC material with an effective roof width of 750 mm which has five crests and four valleys.
