Open Export ToolThe KERTE WB-SS-3S-001 is a 3-seater stnless steel public wting bench built for high-traffic shared spaces, with a streamlined, functional linear form that balances durability and user comfort. Its polished perforated stnless steel seat and back panels feature a uniform open texture, pred with curved chrome-plated steel armrests at both outer edges and a matte black central support crossbeam, creating a clean, professional aesthetic that complements formal and utilitarian interior palettes. Black rubber spacers separate individual seating units to soften visual lines and eliminate contact noise, while four-prong polished chrome end legs anchor the structure with a wide, stable footprint. The bench is constructed with a rigid steel frame, using 1.5mm perforated 201 stnless steel for seat pans and 1.2mm perforated 201 stnless steel for contoured backrests, both finished with smooth rolled, welded edges to eliminate sharp points. Armrests are formed from 25mm diameter polished chrome-plated steel tube, while the central crossbeam uses 2mm thick powder-coated rectangular steel for rigid structural support. End legs are 1.5mm chrome-plated cast steel, fitted with M10 threaded adjustable feet capped with non-marking rubber pads. All fasteners are corrosion-resistant stnless steel with lock washers, installed on the bench underside for tamper resistance, and continuous ground TIG welds seal panel edges to prevent moisture entrapment. Seating surfaces include padded layers over internal bent plywood support structures, with dense foam for extended sitting comfort. Functional design elements support long-term public use: the fixed non-reclining seating is set at an ergonomic angle to minimize mntenance needs, while perforated panels enable continuous r circulation to prevent heat buildup during extended wts. Adjustable feet compensate for uneven flooring to eliminate rocking, and the wide leg base delivers anti-tip stability. Smooth, non-porous surfaces withstand regular disinfection with standard commercial cleaning products, non-marking foot pads protect hard flooring from scuffs, and rubber spacers reduce ambient noise from shifting users. This bench is well suited for hospital and clinic wting areas, transit terminals including rports, rl and bus stations, bank and government service halls, campus common areas, covered outdoor public wting zones, and industrial facility reception or break spaces. For procurement, teams should note the bench ships semi-assembled, with strghtforward on-site installation, and confirm material grades, packaging configurations, and assembly timelines with suppliers prior to bulk orders to align with project logistics and operational requirements. Bulk freight calculations can reference standard contner loading capacities to optimize shipping budgets for large-scale furnishing projects.
