Single-sided bolts - black technology for assembled steel structures (blind hole bolts)

The core concept of prefabricated buildings is “highly factory prefabricated and fast on-site assembly”. Its outstanding advantages are fast construction speed, short construction period, low labor demand and low environmental pollution. Compared with other structural forms, steel structures are the easiest to achieve standardization of design, factory construction of component production, assembly and mechanization of construction, socialization of product supply, and serialization of market consumption. Therefore, the prefabricated steel structure system can best reflect and exert the core advantages of prefabricated buildings, with the most development potential and promotion value.
