This heavy-duty 4-door steel locker is built for factory floors and industrial changing rooms. The body is commercial-grade cold-rolled steel, fully welded, with a powder-coated finish. Four individual compartments, each with its own lock — workers drop their phones and wallets in before their shift, change into work clothes, lock it up, and collect it all at knock-off. No more carrying personal stuff around the factory floor all day.
It stands 1850mm tall, 850mm wide, 460mm deep. Each compartment fits a work uniform plus a pair of safety boots, and there’s room on top for a hard hat. Four compartments per unit means one row covers a whole shift team.
Factory conditions are nothing like a school locker room — there’s oil mist, metal dust, and grinding debris in the air. Carts and forklifts bump into things. Parts get dropped against cabinet doors. Three things matter here: thick enough steel to take hits, welded frame that won’t go crooked, and a powder coat that oil wipes off.

Key Features
Cold-rolled steel that handles a factory floor
Factory lockers need real steel, not the thin sheet metal you find in cheap cabinets. This one uses commercial-grade cold-rolled steel — thicker and harder than basic iron sheet. When a utility cart bumps into it or a pallet jack clips the corner, the surface doesn’t dent and the door doesn’t jam. The toughness of the steel determines how long the locker lasts. This one is built to stay straight for years.
Powder-coated finish, oil wipes off clean
Two things ruin painted lockers in a factory: oil stains and grinding dust. Regular paint has microscopic pores — oil soaks in, you can’t get it out, and over time the paint peels and rust shows underneath. Powder coating is different — the surface is dense and non-porous. Drip some machine oil on it? Wipe with a rag, it’s clean. The shop floor cleaner runs a damp cloth over the doors, and they look like new.
Fully welded frame, carts won’t knock it out of square
On a busy factory floor, people walk fast and equipment moves tight. Lockers get hit — it’s not a matter of if, it’s when. A bolted cabinet loosens within months — doors go out of alignment, gaps open up, locks don’t line up anymore. A welded frame doesn’t have that problem. The joints are fused, not screwed. This locker’s body and door frames are welded as one piece. Put it against the wall, and ten years later it’s still square.
Individual locks, shift-change safe
Factories run two or even three shifts. Workers rotate through the same lockers. Each door has its own lock with its own key — lock it at the end of your shift, open it at the start of the next one. Phone, wallet, keys — they stay put. Handover between shifts is simple: your locker, your key, your stuff. The lock cylinder is brass pin tumbler — the same mechanism used in commercial padlocks — not the cheap spring latch that a screwdriver can pop.
1850mm height fits more than standard
Fifty millimeters taller than a standard 1800mm locker. That extra space means a full-length work coat hangs without bunching at the bottom, and there’s still room for a hard hat on top. The 460mm depth handles work clothes plus safety boots in one compartment. If your factory has a color theme for equipment and walls, these lockers come in custom RAL colors at no extra charge.
Where to Use
Factory changing rooms
Manufacturing plants, auto parts factories, electronics assembly lines — anywhere shift workers change in and out of work clothes. One team changes, then the next. Four-compartment lockers take up less floor space per person than six-door units. Line them up along the changing room wall, give each worker a key, and the system runs itself.
Industrial park shared facilities
Multi-tenant industrial parks often have one central changing room. The lockers there get heavy use from different companies’ workers, day in and day out. They need to be tough, low-maintenance, and hard to break. Fully welded frame plus powder coating means near-zero upkeep — no seized hinges, no peeling paint, no loose doors for a decade or more.
Machine shops and fabrication workshops
Oil mist, metal chips, high humidity from coolant mist — this is one of the toughest environments for any storage equipment. Standard painted cabinets start peeling within three years here. The powder-coated surface on this locker is sealed tight — oil doesn’t seep in, metal dust doesn’t get trapped in the coating. The lock cylinder has a dust cover, and the hinges are heavy-duty steel that doesn’t rust from coolant exposure.
Warehouse and logistics center staff areas
Warehouse floors are busy — forklifts everywhere, pallets stacked high, inventory moving constantly. Staff need a secure spot to store personal items that doesn’t get in the way of operations. At 1850mm tall, these lockers tuck neatly against a side wall without blocking sight lines. Four compartments work well for staggered shift teams from different departments.
Installation
Available pre-assembled or knock-down (KD).
Pre-assembled units come fully welded — about 60kg per cabinet. Two workers carry it into position, done. Most factory floors have a forklift or pallet jack available, which makes positioning even easier. No tools needed, no assembly time.
KD units ship flat — panels stacked, hardware bagged. This cuts shipping volume by roughly half, which matters when you’re importing by container. Assembly uses the included hex key. Three workers can put together 30 to 40 units in half a day. Factory maintenance staff can handle the assembly — no specialist required.
One practical note for factory changing rooms: most factory floors are sealed concrete or epoxy-coated. If the floor has a drain slope, check it before installation. Shim the locker feet if the floor isn’t level — otherwise the doors won’t close properly.
What to Look for When Buying Factory Lockers
Don’t buy factory lockers on unit price alone.
Suppliers who quote the lowest price usually use the thinnest steel. It feels light and flimsy from day one. Within two years the doors won’t close flush, and one hit from a cart puts a permanent dent. When you need to replace them, the cost of new cabinets plus installation labor plus downtime on the changing room is more than the difference you saved upfront.
Three things matter more than price:
- Steel gauge — commercial-grade cold-rolled steel is the minimum. Anything thinner is a short-term solution.
- Welded vs bolted — fully welded costs more to build, but lasts three times as long as bolted cabinets in a factory environment.
- Surface finish — powder coating over paint. Not negotiable in an oily, dusty shop floor.
Every locker from Hengna goes through structural integrity testing and coating adhesion testing before it leaves the factory — not spot checks, every single unit. For bulk orders, we ship a sample first so you can see the build quality, test the lock, and feel the steel yourself.
