Steel structure and space structure: mainly applicable to industrial and civil steel structure
engineering for large-scale stadiums and gymnasiums, large-span and large-space factory
buildings, airports and exhibition halls. This is a much mature industry in China. The design
and construction of structural systems such as latticed frames, latticed shells, truss frames
and portal rigid frames are the business highlight of our company.

Curtain walls and interior & exterior decoration: Mainly applicable to supporting works for
large-scale steel structures. As a rising industry in recent tens of years, its materials and
technology have become quite mature in China.

Cable-membrane structure: mainly applicable to the construction of large-scale stadiums and
gymnasiums. Starting from the 1970s, the cable-membrane structure engineering has been
rapidly developed in recent tens of years in China, and belongs to a new type of space
structure engineering. As a kind of high-molecular composite materials, membrane materials
can be extensively applied to numerous areas.
