Heavy-Duty Metal Sofa Legs Wholesale Collection for Couches & Sectionals

产品描述

The heavy-duty metal sofa legs collection manufactured by Zhaoqing Gaoyao Jinli Zhengkai Hardware Factory (BLS Hardware) provides structural foundation support across contemporary modular sectionals, velvet couches, living room credenzas, and commercial seating plinths. Precision-stamped and formed from heavy-gauge Q235 cold-rolled carbon steel plate (2.0 mm to 2.5 mm thickness) and structural extruded aluminum alloy, our multi-model lineup includes modern slanted tapered cone legs, heavy-duty three-prong trident feet, geometric triangular corner brackets, and hollow leaf profiles. Every design is engineered with standardized 120 mm to 150 mm heights to guarantee unrestricted floor clearance for autonomous robotic vacuum cleaners equipped with LiDAR navigation domes. All models undergo strict structural testing, delivering certified static load ratings exceeding 800 kg (1,760 lbs) per set of 4 legs in compliance with ANSI/BIFMA X5.4 commercial standards. Automated multi-layer electroplating (titanium mirror gold, bright chrome, gunmetal) and electrostatic matte black powder coating withstand 72 hours of ASTM B117 neutral salt spray testing, ensuring zero tarnish or oxidation during trans-oceanic container shipping. We provide full OEM and ODM customization, supporting bespoke heights (100mm to 200mm), specialized mounting flange hole spacings, and private-label packaging. Packed in individual scratch-resistant poly bubble sleeves, 40 to 50 pcs per 5-ply export master carton with honeycomb cell dividers, palletized for ocean container shipping. Standard production lead time is 20–25 days (evaluation samples dispatch in 3–5 days). 100% of sample evaluation fees are fully deductible against your first bulk container order.
