The PC BU is engaged in the production and sales of precast concrete components, and at the same time is the experimental base for the group’s new products and technologies. Product types include prefabricated laminated slabs, prefabricated floor slabs, prefabricated columns, prefabricated external wall panels, prefabricated beams, prefabricated shear walls, prefabricated caissons, prefabricated air conditioning panels, prefabricated bay window panels, prefabricated bay windows, prefabricated balconies, prefabricated pipe corridors, etc. Precast concrete components are the basis for realizing the prefabrication of the main structure. It has the following characteristics: good structural performance, factory-made production can effectively ensure the mechanical properties of the structure, and the dispersion is small. The construction speed is fast, the product quality is good, and the surface finish is high, which can achieve the decorative effect of fair-faced concrete, so that the structure and the building are unified and coordinated. Factory production is energy-saving, is conducive to environmental protection, and reduces noise during on-site construction. It has good fire resistance and heat preservation performance.
