With the development of construction, there are three main product types of building formwork: architectural red surface formwork, phenolic mirror surface formwork, and membrane coated formwork. The laminated formwork is the best quality of the three types of products, and its surface is coated with black or red coated paper made of special glue on both sides, which makes the surface of the laminated formwork smoother and smoother. The number of times it is used is higher than that of architectural red faced formwork and phenolic mirror faced formwork of the same thickness. Its manufacturing process is complex, more materials are used, and the price is higher than that of the two types of formwork. It is mostly suitable for high-rise buildings Bridge construction and other projects with high strength requirements.
