No cracks, no damage. Building Materials Co., Ltd. Yancheng Yingtian share with you about the in-situ concrete hollow floor structure design method, Yancheng Yingtian Materials Co., Ltd. sells hollow core slab mold products, new and old customers here. The following information from the industry should be days of Yancheng Building Materials Co., to provide you with the hope to help my friend. Factors Because the project uses a new patented technology, there are some difficulties eps Hollow Floor in the construction process relatively speaking, in order to ensure the smooth progress of the construction of the hollow floor patent, in the organization and management of the construction process requires sound project management system. The first is to be a reliable quality, must be carried out under professional monitoring company in the production, transportation, storage, and other process and ensure the quality of materials and duly arrived; followed by the installation and fixed process pipe is the key to control the quality of construction should be avoided Overall Floating floor; and finally pouring concrete quality directly affects the success of the project. grc hollow floor, Wenling hollow floor, building materials should be days should be days by the Yancheng Building Materials Limited.
