产品描述

The 3-Seat Public Beam Waiting Chair with Aluminum End Supports, model PU-B3-AL-780, is a purpose-built fixed tandem seating solution designed for heavy-use public environments. Presented in a clean linear layout, the unit features three connected seats aligned along a single central support beam, with curved armrests positioned only at the two outboard ends and no middle dividers between seats to create an open, orderly visual profile finished in blue with polished silver-toned aluminum end components and protective black end caps.
Its robust construction combines layered, durable materials: self-skinning integral polyurethane seat and back shells formed over cold-rolled steel inserts, with contoured waterfall seat fronts and angled backrests for upright seated support. The splayed A-frame end legs and integrated armrests are made from die-cast aluminum alloy, while the triangular central support beam, mounting brackets, and internal under-seat support ribs are fabricated from treated, powder-coated steel. All metal components carry a uniform electrostatic powder coating, and bolt-adjustable non-marking, non-slip rubber glides sit at each floor contact point to protect flooring and enable level placement, with optional anchor bolts available for permanent fixed installation.
Designed for practical high-traffic use, the non-porous polyurethane surfaces support quick wipe-down disinfection without liquid absorption, and the fixed structure offers no recline, fold, or rotation functions to reduce maintenance needs. The beam-based architecture also supports modular expansion, allowing users to add three additional seat positions or matching series side tables as needed. The chair’s splayed outrigger leg design distributes weight across four floor contact points to deliver reliable anti-tip stability.
This seating solution is well suited for a broad range of commercial and public spaces, including airport terminal waiting areas, hospital and clinic waiting rooms, railway and bus station concourses, bank and government service halls, shopping mall public rest areas, and school campus lobbies. For procurement planning, note that each unit ships across two cartons, requires on-site assembly, and supports flexible installation either as free-standing leveled seating or permanently anchored fixed seating, making it adaptable to both temporary space configurations and long-term public area fit-outs.
