ABC light steel structure building (ABC-LSSB) technology originates in North America. ABC-LSSB is typical PEMB category. The building mainly comprises of light-duty mainframes and is normally 1 or 2 storey. Metal materials are used for the structural members and the roof & wall cladding system, such as steel plates for mainframes and color painted metal coils for paneling.

This type of building features large internal space, flexible partitioning and construction cost saving,  and suits all low-rise industrial applications such as manufacturing facility, warehouse and commercial facilities like large-scale supermarket, shopping mall and cold storage and etc. For a single building, the dimensions of building could reach as much as 60m+ for clear span, 210m + for building width and 360m+ for building length.

This type of building has rigorous requirements for wind resistance, weather tightness and anti-condensation performance of cladding system.
