Open Export ToolThe WEINENG 3-Seat Backless All-Metal Public Wting Bench, model WT-BN-3S-MTL-BKLS-001, is a streamlined beam seating solution designed for consistent performance in high-traffic settings. Its open, backless form connects three individual seat sections along a continuous rounded structural side beam, with no armrests to allow flexible seating access from either side of the unit. A uniform matte silver finish across aluminum components, pred with dark grey recessed connection brackets and triangular impact-resistant ABS end caps, creates a clean, minimalist silhouette that blends unobtrusively with functional public space design. Splayed Y-shaped die-cast aluminum outrigger legs form a stable support base, with no middle support leg required to block floor access beneath the seat. Construction centers on a durable steel frame pred with aluminum alloy components: 1.5mm thick anodized aluminum seat panels mount to a rounded rectangular extruded aluminum mn beam via reinforced die-cast aluminum brackets, secured with stnless steel M8 hex bolts and lock nuts. Each leg terminates in an adjustable leveling foot with a zinc-plated steel stem and non-slip nylon base pad, while all metal surfaces receive a 60 micron polyester powder coating for corrosion resistance. All exposed edges are rounded to eliminate sharp contact hazards, and structural joints are rated to resist deformation under concentrated load. Practical design features support low-effort, long-term operation: four total leveling adjustment points compensate for uneven flooring to eliminate wobble, while nylon foot pads prevent hard floor scratching and reduce noise from movement. Generous clear floor clearance beneath the seat allows full passage of standard cleaning tools including brooms, mops and robotic vacuums for simplified mntenance. The beam ends include integrated connection points to extend runs with additional matching seat units as needed. The all-metal non-porous surface supports easy disinfection, and the splayed leg base provides anti-tip stability to withstand leaning or crowd impact. The corrosion-resistant build also holds up to light moisture exposure for covered semi-outdoor placement. This bench is well suited for a wide range of commercial and public spaces, including hospital outpatient wting areas, trn, bus and rport transit wting zones, bank and government public service halls, covered outdoor wting shelters, school campus common areas, and temporary event queuing setups. It ships as a single fully assembled unit requiring only foot adjustment on site, with protective foam and corrugated packaging to prevent transit damage. Procurement teams should note that units are stackable for efficient bulk shipping, and plan layout spacing to accommodate the modular connection capacity for extended row configurations where needed. Per-seat safe working load limits align with standard public use requirements, and the robust metal build supports expected long-term service under normal indoor public operating conditions.
