The main building structure(columns,beams)requires extremely high vertical and horizontal tolerance to ensure precise operation of stacker cranes and other automated equipment.Floor flatness is critical(e.g.,±3mm),often achieved with high-precision laser screeding.The building and racking can be separate or an integrated"rack-supported"structure.Fire protection requirements are stringent,typically employing Early Suppression Fast Response(ESFR)sprinklers.

Eave height is determined by racking height,typically above 15m and up to 40m or more.Span design considers rack aisle layout and stacker crane reach.The roof must handle sufficient snow and wind loads,and internal drainage is often avoided to prevent leakage risk.Space for equipment installation,maintenance access,and robust power/data networks must be provisioned.
The core facility of modern logistics and supply chains.Used in e-commerce fulfillment centers,regional hubs for third-party logistics(3PL)providers,central distribution centers(CDC)for large manufacturers,and industries requiring high-density storage like cold storage.It is key infrastructure for"goods-to-person"picking and unmanned warehousing.
