Product Description

The 3-Seat Perforated Metal Public Waiting Beam Seating, model WB-3S-PM001, is an unbranded waiting area beam seating solution built for consistent performance across shared public environments. It features a linear, streamlined layout with three individual seat positions bookended by polished silver outboard armrests, with no intermediate dividers between seats to support flexible, open seating access. The cohesive silver finish across all metal components creates a sleek, understated visual profile that aligns with functional public space design standards. Its overall dimensions measure 1800 x 740 x 850 mm, with each seat offering 500 mm of usable width, 505 mm of usable depth, and a 450 mm seat height from the floor, paired with a 400 mm tall slightly angled backrest and 620 mm high armrests for consistent ergonomic support. Construction centers on heavy-duty metal components: 1.5mm perforated cold-rolled steel forms the silver powder-coated seat and back panels, mounted to a 2.0mm thick anti-rust treated Q235 cold-rolled rectangular steel support beam. Splayed, chrome-plated die-cast aluminum alloy legs anchor the unit, fitted with non-slip adjustable rubber glides with steel threaded stems for stable placement. 1.2mm thick polished die-cast aluminum alloy forms the outboard armrests, while 4mm thick powder-coated stamped steel plates connect core components, with CO2 shielded arc welds ground smooth to eliminate exposed sharp edges. All surfaces use lead-free electrostatic polyester powder coating, with fully deburred edges for user safety. Internal seat support uses a 14 mm bent plywood base, paired with seat foam of 45 kg/m³ density and 65% rebound, and 38 kg/m³ density back foam for baseline comfort. The fixed, rigid seat pans include a rolled front edge, with no recline or height adjustment, and the perforated seat and back surfaces enable consistent ventilation to reduce heat buildup during extended use. The curved outboard armrests provide stable support for entry and exit, while the modular beam design supports extension to 2, 4, or 5 seat configurations by swapping the support beam length. Pre-drilled mounting points accommodate optional PU seat cushions or side tables, and the adjustable glides allow stable placement on uneven hard floors. Each seat supports a 120 kg recommended maximum user weight, with 150 kg per-seat static load capacity, 2000 N weld joint static failure load, and 5 years of surface corrosion resistance for long-term high-traffic use. This seating is well-suited for airport terminal waiting areas, hospital and clinic waiting zones, bank and service hall reception areas, railway and bus station concourses, school administration and lobby areas, and indoor public corridor rest points, where its easy-to-clean perforated surface, vandal-resistant fixed structure, and low-maintenance finish reduce long-term upkeep demands. Procurement teams should note the unit ships in two cartons per set, requires 40 minutes of assembly time per unit, and has a fully assembled net weight of 42 kg. The fixed non-reclining, all-metal construction is purpose-built for high-traffic public use, with no soft upholstered surfaces that trap debris, and the compact 3-seat footprint fits narrow walkway rest zones without obstructing circulation paths.
