The WEIKE model TW-CRS1750is a 3-seater metal public tandem beam waiting chair built for consistent, high-traffic use across commercial and public settings. Its linear, fixed three-position layout sits on a shared central beam, with curved polished chrome armrests positioned only at the two outer seating positions for unobstructed access between seats. Fixed ergonomically angled backrests and seat panels feature evenly spaced perforations across their surfaces, creating a clean, streamlined visual profile paired with a neutral silver finish that integrates seamlessly with formal and functional interior schemes. The chair’s robust construction draws on carefully selected metal components for long-term durability. Seat and back panels are formed from perforated cold-rolled steel sheet, mounted to a thick-walled pentagonal cold-drawn steel central support beam. End armrests use formed iron with a polished chrome finish, while splayed cantilever support legs and connecting brackets are fabricated from welded formed iron and steel. All metal surfaces receive an anti-rust phosphating pretreatment followed by electrostatic powder coating for wear resistance. Pipe ends are fitted with injection-molded ABS plastic caps, and each foot features a zinc-plated steel cover paired with a non-slip rubber base, adjustable via threaded hardware to compensate for uneven floors. All connections use Grade 8.8 zinc-plated steel bolts and lock nuts for structural rigidity. Functional design details support daily public use: perforations on seat and back panels enable consistent air flow and liquid drainage, while smooth, gap-minimizing welded joints allow quick wipe-down sanitization between uses. The fixed beam structure prevents unauthorized rearrangement, and open beam ends support modular connection of additional seat units or accessory tables to expand seating capacity as needed. Each seat supports substantial static load, with matched load ratings for armrests and individual leveling feet, and a recommended service life suited to continuous public deployment. This seating solution is well suited for hospital outpatient waiting areas, airport, railway and bus station concourses, bank and public service hall reception zones, cinema and event venue lobbies, factory staff break areas, and covered outdoor public queue zones. Procurement teams should note that each unit ships across two cartons, with a straightforward assembly process per set; the packaging dimensions and loading capacity for standard 20-foot containers make bulk ordering efficient for large-scale installation projects, while the smooth, sanitizable surface and heavy-duty build reduce long-term maintenance demands across high-footfall sites.
