The customer will constructe at a long time with aluminum formwork system. Engineering Management Department analyse this project in consideration of the verticality of wall , smooth , the levelness of the slab, the size of section, visual quality and the challenge of new technology. Meanwhile, we control product from choosing material, designing and processing, erecting and examing formwork system. Please builders are according to specification to constructe. If any question, please contact to us.
