Product Description

Its visual form consists of two connected double-bunk bays divided by a central shared support and ladder assembly, creating a symmetrical, space-efficient layout with two upper beds and two lower beds arranged in a single connected frame. The frame features a light-gray powder-coated finish, with clean linear lines defined by C-profile and square-tube steel members, while solid fir bed boards add a natural wood contrast to the metal structure. Construction relies on a robust steel framework. Side main uprights use special C-profile steel with a light-gray coated finish, while center main uprights are square steel tubes that form the central shared support for both bays. Rectangular steel tubes link the uprights to create a rigid frame, and smaller square steel tubes form guardrails and auxiliary frame components. Each bunk is supported by C-profile steel side rails along the perimeter, plus multiple square steel support rails beneath the sleeping platform. The ladder, bolted to the central frame, is built from square steel tubing with cold-rolled patterned steel treads for anti-slip footing. Upper-berth guardrails are made from square steel tube with welded or fastened joints, and bed boards are four-side planed solid fir. Practical functions prioritize safety and utility for multi-occupant use. The unit accommodates four users, with one person per sleeping position. A central vertical fixed ladder provides access to both upper platforms, with raised patterned treads that deliver slip resistance during climbing. Tubular guardrails surround the exposed outer and end sides of each upper bunk to prevent falls, while low tubular head and end rails on lower bunks help retain bedding and define individual sleeping spaces. Beneath both lower bunks, parallel lower tubes form open shoe racks for convenient storage. The shared central upright and ladder assembly unify the two bays into a single stable structure. This bunk bed is suited for a range of commercial and institutional spaces. It works well in boarding-school dormitories, supporting four students per unit with central ladder access and separate sleeping positions. For worker and staff quarters, it fits high-density employee housing needs, benefiting from durable steel framing and replaceable wood bed decks. It also serves hostel and budget accommodation settings, offering compact four-bed capacity paired with under-bed shoe storage and fixed upper-berth guard protection. For procurement planning, the set ships in multiple cartons, with a total packaged gross weight per set and defined packaging volume. Each set requires a reference assembly time, and the largest carton dimensions help coordinate delivery and access through doorways or elevators. The frame targets a 10-year service life under normal dormitory use, supporting long-term value for facilities with consistent occupancy.
