The YUANTONG STC-4D-1800 4-Door Steel Storage Cabinet is a robust full-height storage solution designed for secure, organized storage across commercial and residential settings. Its clean, streamlined silhouette features four flush-mounted doors split evenly into upper and lower double-door sections, with recessed keyed locks and no external protruding handles to prevent snagging in high-traffic areas. A rsed base plinth lifts the cabinet body off the floor to protect contents from surface moisture, while four nylon-tipped adjustable feet at the base corners compensate for uneven flooring, and included anti-tip brackets secure the top rear to a load-bearing wall for safe operation when doors are fully open to 110 degrees. Constructed primarily from cold-rolled steel, the cabinet uses appropriately gauged sheet metal for balanced rigidity and durability: the main carcass, horizontal midpoint divider and back panel use thinner gauge steel with seam and spot welding to form a rigid, warp-resistant frame, while door panels use thicker steel with folded reinforced edges for long-term alignment consistency, and internal shelves feature folded perimeter lips for enhanced load support. All exposed cut edges are folded into a double-layer hem and fully deburred to eliminate sharp hazards. The entire surface is finished in epoxy polyester powder coating, available in 6 color options including light grey, off-white, black, blue, coffee and military green, with a matte finish that resists routine scuffs from dly use. Functionally, the cabinet is split into two independently locked upper and lower compartments, each fitted with one adjustable shelf that repositions in 32mm increments along slotted internal uprights to accommodate items of varying heights, from A4 documents and lever arch binders to small hand tools and spare equipment. Each shelf supports a uniform static load of 50kg, with a total cabinet load capacity of 200kg, sized to support shared storage for up to 20 users. The recessed zinc alloy keyed locks are rated for 10,000 operation cycles to support long-term access control. This cabinet is well-suited for a wide range of spaces, including open plan offices, administrative departments and central file rooms for document and supply storage, manufacturing workshops and staff changing rooms for personal belongings and tool storage, schools, hospitals and government facilities for public records and equipment, retl back-of-house areas and stockrooms for inventory, and IT departments for secure storage of spare peripherals and maintenance tools. It may also be used in residential garages, home offices or utility rooms for durable, lockable household storage. For procurement, buyers should confirm final material specifications directly with the supplier prior to purchase, as standard construction details follow mid-tier mass-market steel cabinet conventions. The unit ships in knock-down or fully assembled configuration in protective packaging, with an assembly time of 40 minutes for two people. Planners should account for standard loading quantities for freight consolidation, and ensure installation leaves appropriate rear clearance for r circulation when positioned against a load-bearing wall.
