The Stepped Dark Grey Lockable Office Storage Sideboard, model OF-STP-06D-OS-1830, features a modern, asymmetrical stepped silhouette defined by three tiered height modules: a left low section at 650mm, middle medium section at 730mm, and right high section at 810mm, with an overall footprint of 1830mm wide, 510mm deep, and 810mm tall. A recessed open display niche sits within the middle module, measuring 580mm wide, 450mm deep, and 280mm tall, backed with dark matte wood veneer laminate to create a visual focal point alongside enclosed cabinet sections. Each cabinet door is 305mm wide with an 18mm particleboard core, set atop a powder-coated steel plinth base with 30mm floor clearance for easy under-unit cleaning. Constructed for commercial use, the unit uses E1 grade engineered wood composite for its main carcass, finished with matte dark grey melamine laminate that carries a 2000-cycle surface scratch resistance rating. All edges are sealed with 2mm thick PVC edge trim, while the back panel is formed from 9mm hardboard. Hardware including hinges, locks, and handles is made from powder-coated zinc alloy, with 110-degree soft-close concealed hinges that enable full, quiet access to interior spaces. The product has a net weight of 73kg, with a maximum distributed top surface load of 73kg, 50kg maximum load per enclosed cabinet compartment, 25kg maximum load per adjustable interior shelf, and 15kg maximum distributed load for the open niche. Practical functionality is tailored to office workflow: keyed cam locks on each door pair secure three separate enclosed storage zones, which support letter, legal, and A4 size hanging file folders. All enclosed compartments include 5-position height-adjustable shelves held in place with metal pins to accommodate files, supplies, or equipment of varying sizes. The middle open niche provides convenient access to frequently used items and display space, while two included steel wall anchors deliver anti-tip safety for full-load or open-door use. This sideboard fits a range of professional settings: it serves as back-wall storage behind executive desks, shared secured storage along open-plan office partition walls, combined storage and display for reception areas, auxiliary supply storage for conference rooms, and multi-function storage for small private or home offices. It is designed for use by up to 15 office staff, and pairs ideally with 2000mm wide executive desks, ergonomic office chairs, and matching mobile filing pedestals. For procurement, note the unit ships as one set split across cartons, with a total packaged gross weight of 100kg and total packaging volume of 0.65 cubic meters per set; reference assembly time is 40 minutes per set. When specifying, confirm load requirements align with rated capacities, and plan for secure wall anchoring during installation to support safe long-term use.
