Product Description

The 12-Door 3-Column Steel Personnel Storage Locker (model SL-12D-3COL-001, unbranded) is a purpose-built steel storage solution aligned with standard industry dimensions for multi-door personnel lockers. Its visual layout follows a symmetrical 3-column, 4-row configuration, with a uniform matte light grey epoxy-polyester hybrid powder-coated finish. Each individual compartment door features a recessed card holder slot at the upper section for user identification, a punched steel ventilation grille at the lower section for r exchange, and a recessed zinc-alloy handle with an integrated cam lock positioned for ergonomic access. The unit sits on a rsed folded steel base plinth that elevates the cabinet above floor level, with clean, strght frame lines and evenly spaced door gaps that create a streamlined, professional appearance suitable for high-visibility shared spaces. Constructed from cold-rolled steel, the unit uses 0.8mm thick steel sheet for door panels with folded edge reinforcement to resist bending, and 0.6mm thick steel sheet for the main frame and internal partitions, which are welded to the frame to form 12 separate, fully enclosed compartments. All steel components receive phosphate treatment prior to coating for standard corrosion resistance, with steel pin hinges welded directly to doors and the main frame to support long-term use. Each door pivots outward 180 degrees to provide unobstructed access to the compartment interior, with a 50,000-cycle hinge durability rating and 20,000-cycle lock durability rating suited to regular dly access. Functionally, every compartment is fitted with an independent key-operated cam lock, with two keys provided per lock to secure personal belongings. The integrated punched ventilation grilles enable consistent r exchange to reduce odour buildup from stored clothing, footwear or damp items, while the recessed card holders accept paper labels to mark assigned users by name, number or department. Each compartment supports a 25kg static load, sufficient to hold work uniforms, bags, shoes, folded outerwear, small personal effects or sports equipment, with a total usable storage volume of 475L across the entire unit. The smooth powder-coated surface resists common stns and wipes clean easily with non-abrasive cleaning agents, while the welded frame with knock-down bolted connections delivers stable, wobble-free performance when placed on level flooring. This locker is well suited for a wide range of commercial and residential-adjacent shared spaces, including office staff changing areas, factory and workshop staff rooms, secondary school and college locker rooms, gym and sports facility changing areas, and public service spaces such as libraries, community centres and transport hubs, where assigned or temporary secure personal storage is required for 12 individual users per unit. For procurement planning, note that the unit ships as a single flat-packed package, with an 60-minute assembly time for two people using standard hand tools. Buyers should confirm exact material specifications, hardware details and finish composition with suppliers prior to final purchase, as some construction details reflect standard industry configurations for this product category rather than verified unit-specific measurements.
