Besides for the large wall and columns formwork use, the H20 timber beam formwork system is more often to be used and adaptable to most any type of slab and height configuration, especially for those slabs with more beams. Jiaquan H20 timber beam formwork system is similar to the traditional method, but stringers and joist are replaced with the standard size H20 timber(wood) beams and supports are replaced with adjustable metal props. This makes this method more systematic and reusable.
