Our Advantages
A. Maximizing Capacity in Minimal Footprint Unlike standard 6-door configurations, the 3L-B4 doubles the user capacity within a standard 900mm wide footprint. It allows facility managers to accommodate 12 individual users per unit, effectively halving the floor space required for staff changing rooms or student locker areas—ideal for projects where maximizing density is the top priority.
B. Engineered for High-Frequency Industrial Use Built from premium SPCC cold-rolled steel, the 3L-B4 is designed to withstand the rigors of heavy daily use in demanding environments. Each of the 12 doors features reinforced hinges, individual ventilation louvers for constant airflow, and integrated name card slots for easy user identification in high-turnover settings.
C. Global Logistics & Shipping Optimization Leveraging a mature Knock-Down (KD) structure, the 3L-B4 is flat-packed to reduce shipping volume by up to 60%. This ensures maximum container utilization for international wholesale buyers, significantly lowering the per-unit ocean freight and landed cost—a critical advantage for large-scale government or corporate procurement.
D. Professional Security & Customization Each compartment is secured by independent locking mechanisms to protect personal belongings. We offer diverse lock options including key, pad-lock, and digital combination systems. Full OEM/ODM support is available for project-specific RAL colors, steel thicknesses (0.5-1.0mm), and interior configurations.
