The Square Two-Tier Black Glass Z-Frame Coffee Table, model CT-SQ-BG-ZF-850, is an unbranded public furniture piece defined by sleek contemporary geometry. Its layout pairs two tiered glossy black tempered glass surfaces with a matte black Z-shaped metal support frame, creating an open, visually light silhouette without bulky side panels. The 8mm thick top surface extends with a uniform overhang above the frame, while the 5mm thick lower shelf sits above the floor, creating an unobstructed open storage zone beneath the primary work surface. The frame is constructed from 1.2mm thick powder-coated steel square tube, joined with zinc-plated steel bolts and barrel nuts for secure connection. All glass edges are finished with black PVC edge banding, and the tempered explosion-proof safety glass is treated with a stain-resistant nano-coating. Non-slip plastic foot pads are fitted to the base of each frame leg, and the Z-frame geometry delivers anti-tip stability for regular daily use. In function, the flat top surface supports drink service, decor placement, and light display items, with a distributed load capacity of 100kg, a static uniform load reference of 150kg, heat resistance up to 80°C, and abrasion resistance tested to 3000 cycles. The powder-coated frame finish offers 48 hours of salt spray corrosion resistance, and the lower open shelf accommodates upright book storage, magazines, and small decorative objects. Surfaces wipe clean easily with a non-abrasive damp cloth, resisting common household stains, while integrated foot pads prevent scuffing on both hard flooring and plush rugs. Dual glass surfaces distribute weight evenly across the steel frame to reduce structural stress during use. This table is ideally suited for placement as a central living room table positioned on an area rug in front of seating, as well as for small urban apartment lounge spaces, where its compact square footprint fits streamlined floor plans. Its high-contrast glossy black and matte metal finish pairs seamlessly with modern minimalist interior design schemes. For procurement, note that the product is delivered as flat-pack self-assembly units, with one set split across two cartons for transport. Each set includes the required hex key and all connection hardware, with a reference assembly time of 40 minutes per unit. Total packaged gross weight reaches 90kg per set across the two cartons, with a total packaging volume of 0.55 cubic meters, requiring appropriate loading and receiving space for bulk orders. The product requires no specialized tools for on-site assembly, and its durable surface treatments support consistent long-term use in high-traffic shared residential or public lounge settings.
