Product Description

The 3-Seat Perforated Metal Beam Public Waiting Chair (model WCH-M3-XL, unbranded) is a robust beam seating solution designed for long-term public and high-traffic use, featuring a streamlined linear fixed layout with three connected seats, no intermediate armrests for flexible occupancy, and integrated end armrests supported by X-shaped leveling legs at each unit end. Its clean, industrial silhouette combines smooth silver powder-coated metal surfaces with textured perforated backrests for a neat, professional appearance that fits a wide range of functional spaces.
Constructed entirely from powder-coated cold rolled steel with phosphate pre-treatment for outdoor-grade corrosion resistance, the chair uses 1.5mm thick steel plate for rolled-front seat panels, hexagonal-perforated backrest panels, rounded-edge bent tube end armrests, and reinforced X-shaped end support legs. A 2.0mm thick rectangular central steel tube forms the core support beam, with Grade 8.8 heat-treated through-bolts and lock washers securing all seating components to eliminate joint wobble. Adjustable leveling feet with zinc-plated steel stems and non-slip rubber bases compensate for uneven floors, while a 14mm bent plywood internal support board sits beneath seat surfaces. The coating delivers 500 hours of salt spray corrosion resistance, with each seat supporting a 200kg static load, a 10-year structural service life, and a 3-year standard warranty; 12 standard color options are available.
Practical design features support heavy daily use: full perforated backrests reduce heat buildup during extended sitting, rolled rounded seat edges and polished armrest edges prevent clothing snags and minor injuries, open under-seat clearance and perforated surfaces enable fast, unobstructed cleaning and debris removal, and pre-drilled mounting points support optional 30mm PU seat cushions or intermediate side tables for customized setups.
This seating is well suited for hospital and clinic waiting areas, airport and railway station concourses, bank and public service hall waiting zones, school administration reception areas, and covered outdoor waiting shelters, where its resistance to cleaning chemicals, low maintenance requirements, and stable construction support continuous high-volume use.
Procurement teams should note each unit ships in two cartons, with a 40-minute per-set assembly time, and plan for compatible accessories or layout spacing based on fixed overall dimensions; the corrosion-resistant coating supports semi-outdoor installation without additional surface treatment for covered locations.
