The key feature is that the structure is also the envelope;the arched sheets act as both the load-bearing structure and the cladding,minimizing steel usage and offering highly competitive pricing.The beamless and column-free interior provides complete space for stacking and machinery operation.Construction is highly mechanized,using specialized equipment for on-site seaming,making it the fast-building prefab warehouse.The arch shape provides good compressive strength and drainage.

Standard spans range from 12m to 36m,with larger areas achieved by adding span units.Steel sheet thickness is typically 1.0mm to 1.5mm.Colors can be customized.As it is a single-layer metal sheet,thermal insulation is poor,suitable only for temperature-insensitive materials.Natural ventilation roof turbines and end walls can be installed.
Primarily used for storing bulk materials like grain,feed,fertilizer,coal,and cement.Also used for temporary material shelters on construction sites,scrap recycling yards,and various sports training facilities.Its low cost gives it a broad market in agriculture and resource industries.
