When sourcing for a 4S Store (Sale, Spare part, Service, Survey), the building must feature a high-span steel structure to allow for a column-free showroom. Ensure the curtain wall glass is tempered or laminated with a thickness of at least 10mm-12mm for safety and thermal insulation. For the service workshop area, the flooring must use industrial-grade epoxy resin or heavy-duty anti-skid tiles capable of withstanding a load-bearing capacity of >5 tons per square meter to support vehicle weight and heavy machinery.
