The HAIBANG BC-3D-WOOD-1200 is a floor-standing 3-door combination office bookcase designed for balanced display and concealed storage, categorized under bookcases and open bookshelves. Its layout splits vertically into two functional zones: an upper section framed for clear glass panels, and a lower section fitted with solid wood-grain doors, plus a dedicated full-height solid door running the full cabinet height along the right side to accommodate oversized stored items. The unit presents a cohesive walnut wood grain finish across all visible surfaces, complemented by polished zinc alloy pull handles with a brushed chrome finish for a polished, professional aesthetic that aligns with formal office interiors. Constructed with durable engineered wood components, the cabinet uses E1 grade particleboard for body panels, finished with matching walnut veneer, and sealed with 2mm thick heat-sealed PVC edge banding that matches the wood finish on all panel edges to resist edge wear. Upper door panels are 5mm thick clear tempered glass set within wood door frames, while internal fixed shelves are built from 18mm thick engineered wood with matching veneer. Locking hardware consists of zinc alloy keyed cam locks, with one lock for each locking door section. Functional design supports multiple storage needs: the clear glass upper section keeps books, binders, and displayed items visible while reducing dust accumulation, while lower solid doors conceal stored items from direct view. Two separate keyed locks independently secure the upper glass section and the right solid door compartment to restrict access to sensitive materials. The full-height right-side storage bay offers continuous vertical space for tall or oversized items, while fixed internal shelves support distributed static loads to hold documents, supplies, and display pieces reliably. This bookcase is well suited for executive offices, where it can be positioned behind a desk to store reference documents and display professional awards, as well as for open general office work areas to organize archived documents and shared office supplies. For procurement planning, note that each unit ships in split cartons, requires on-site assembly, and is designed to pair with appropriate wall anchoring for stable installation. The enclosed storage volume supports both active work materials and archived items, making it a flexible storage solution for professional work environments.
