Main workshop: it is multilayer steel frame or monolayer steel frame (have inner equipment bracket system).

Cornice Height: 24~36m, travelling crane: 20t~32t，structure storey:1~13. Must consider various heavy load and vibration load while designing. Request high manufacturing precision, component variety is miscellaneous, component installation must assort with equipment installation. The requirement of all working procedure from design, production and installation is higher in technical content than normal workshop.

Trestle span is 20~50m, biggest span can be achieved to 70~80m, height is 20m~60m, Concentration pool is light steel structure or lattice structure, diameter normally is 30~60m.
