What is the minimum width requirement for warehouses with vehicle access?

For warehouses with vehicle access, the minimum width of the main passage should not be less than 2.5 meters. Mini Warehouses: Currently in China, there is a nascent form of mini warehouses that specialize in storing items. Some large warehouses offer small-scale storage services where items are stacked together without clear partitions, resulting in a lack of security and privacy. Most regions in China do not yet have the conditions to develop mini warehouses, and currently, only first-tier cities like Shanghai, Beijing, and Shenzhen are seeing a quiet rise in popularity for such services. Single-Story Warehouses: These are suitable for storing metal materials, construction materials, ores, machinery products, vehicles, oils, chemical raw materials, timber, and related products. Warehouses near water transport docks, railway transport hubs, and airports often use single-story buildings to expedite loading and unloading. The overall layout design of single-story warehouses requires interconnected roads to allow trucks and forklifts direct access. Multi-Story Warehouses: These are generally used to store general merchandise, electronic equipment, food, rubber products, pharmaceuticals, medical devices, chemical products, stationery, and precision instruments. The ground floor should have loading and unloading areas where vehicles can directly enter. Vertical transportation of goods typically relies on 1.5 to 5-ton freight elevators. Design considerations should allow for hand carts or forklifts to enter the elevator to speed up loading and unloading. Multi-story warehouses often use slides for unloading goods.
The width of warehouse vehicle access is a critical design point. From the building codes I've encountered, it generally shouldn't be less than 4 meters. Why is that? Because regular trucks are about 2.5 meters wide, and with the space needed for reversing or turning, 4 meters ensures smooth vehicle entry and exit without scraping the walls. If it's narrowed to just over 3 meters, accidents become more likely. I've seen older warehouses with only 3.5-meter-wide access points where drivers were nervous every time they entered or exited, leading to severe door frame wear over time. For new warehouses, I'd recommend widening to 4.5 meters to accommodate fire trucks, significantly improving safety. Also, consider door types like roller shutters that take up space - insufficient width can affect overall warehouse efficiency, causing delays in loading and unloading during traffic jams. This standard isn't arbitrary; it's been repeatedly validated in practice to ensure smooth daily operations and safety.
Having worked in warehouse management for a long time, I deeply understand the importance of vehicle access width. The minimum width should preferably be controlled above 4 meters, and definitely not less than this value. For example, the medium-sized trucks we use daily in our warehouse are about 2.4 meters wide. If the gate is too narrow, say around 3 meters, operations become difficult, often leading to scratches or getting stuck. I remember two years ago when we renovated our warehouse and increased the gate width to 4.2 meters, the accident rate dropped by 70%. We also have to consider fire safety requirements – in case of emergencies, fire trucks need at least 4 meters of width to pass through smoothly. If there are any obstructions or debris piled near the entrance, a narrow passage becomes even more troublesome. That's why I always remind people during planning not to skimp on width – leaving sufficient safety margin can improve overall logistics efficiency and save unnecessary repair costs.
