The 3-Seat Perforated Metal Tandem Beam Public Waiting Chair from Yaqi Furniture, model WCH-3S-MTL-001, delivers durable, purpose-built tandem seating for high-traffic public environments. Designed in a fixed linear three-seat layout with no intermediate dividing armrests, the chair features a neutral silver finish that complements formal public interiors. Its backrest panels use a gradient perforation pattern, and all seat and backrest perimeters have rolled rounded safety edges to eliminate sharp contact points. The 540 mm clear width between outboard curved steel armrests offers generous personal space per seat, paired with a 240 mm tall lumbar support zone, 90 mm thick finished seat cushions, and 70 mm thick backrest padding for balanced comfort during extended waits. Constructed for heavy daily use, the chair combines robust cold-rolled steel components with premium surface treatment. The 3.0 mm thick triangular-profile structural support beam connects to 2.0 mm thick splayed leg assemblies fitted with anti-tilt bracing, using gusseted welded leg-to-beam joints to prevent frame wobble under heavy load. Seat pans and perforated backrest panels use 1.2 mm cold-rolled steel, finished with 70 μm epoxy-polyester electrostatic powder coating over phosphated steel for long-term wear resistance. All connections use Grade 8.8 zinc-plated steel bolts and lock nuts, and the frame includes chrome-plated steel leveling feet with non-slip rubber pads that allow 15 mm of vertical height adjustment to stabilize the unit on uneven floors. Internal seat supports use 14 mm bent plywood, and the knock-down bolted structure assembles in 40 minutes per set with basic hand tools, shipping in two cartons per unit. Each seat supports a 300 kg static load, for a total unit static load capacity of 900 kg, while the unit’s 23 kg net weight supports easy placement and installation. The perforated backrest enables continuous airflow to reduce heat buildup during long sits, and smooth non-porous metal surfaces support spray disinfection to meet strict hygiene protocols. This chair is optimized for airport terminal waiting areas, hospital and clinic waiting zones, railway and bus station concourses, government service hall queuing areas, and bank or office reception waiting spaces, pairing well with a 2.4 m executive desk for coordinated reception layouts. Procurement teams can plan for 135 sets per 20GP container at 85% space utilization to streamline bulk ordering for large public space projects, with the all-metal heavy-duty construction supporting long service life even under constant high-volume use.
