Steel Locker Cabinet Product

Overview

The steel locker cabinet is the standard secure personal storage of schools, factories, gyms, and changing rooms: a tall sheet-metal column, usually 1,800 mm high and 300–400 mm wide, divided into one to six lockable compartments. The product is almost entirely folded sheet steel — a spot-welded Body Carcass carcass, one Locker Door per compartment, a Latch and Lock System on each door, a shelf-and-hook Shelf and Hook Fit-Out fit-out, and a Base and Stand that lifts everything off the floor. Columns bolt side-by-side into banks of any length, which is why the single column, not the bank, is the manufactured unit.

Lockers live a hard life: slammed doors, pried latches, wet kit, and graffiti. Nearly every design decision in the product traces to one of those four abuses.

Construction

The carcass starts as blanked and punched Sheet Metal Panel stock. Each Side Panel is folded from 0.7–0.9 mm cold-rolled steel with return flanges that do three jobs at once: they stiffen the panel, form the rebate the door closes into, and carry the slot rows that locate Shelf Clip. The thin Back Panel squares the box, the flanged Bottom Panel takes boot-and-bag loads, and a Tier Divider splits multi-tier columns into compartments. The front Door Frame is the structural member of the opening, carrying both the hinge knuckles and the latch strikes. Welded lockers spot-weld this carcass in the factory; knock-down versions rivet together on site, trading some rigidity for freight density.

The Top Panel comes flat for ganged banks or sloped at about 30 degrees — the sloped top exists purely so users cannot pile items (or sit) on top of the locker, a housekeeping and hygiene requirement in food plants and hospitals.

Doors and latching

The door is where lockers fail, so it gets the heaviest material in the product: a Door Skin of 0.9–1.2 mm steel with double-return edges that resist bending and screwdriver prying, backed by a welded Door Stiffener channel. Pressed Vent Louvers at the top and bottom create a chimney of airflow through the compartment to dry damp clothing, sized so fingers and coat hangers cannot reach the latch through them. Two welded Door Hinge knuckles (or a continuous piano hinge on heavy-duty lines) are rated for tens of thousands of slam cycles, with Door Bumper pads on the frame to quiet the slam itself.

Latching ranges from a single spring hook to a full three-point system. In the three-point design, lifting the recessed Recessed Handle raises a vertical Latch Rod inside the door stiffener, retracting Latch Hook at the top, middle, and bottom of the frame simultaneously — a pried door corner then has no free edge to work against. Security is user-supplied or facility-managed: a Padlock Hasp through the handle pocket takes a padlock up to about a 9 mm shackle, while a keyed Cam Lock (normally part of a master-key suite) serves facilities that control access centrally. Coin return, digit-combination, and RFID locks all bolt into the same door prep.

Interior and base

A full-height compartment ships with a Hat Shelf about 250 mm down from the top, a Coat Rail beneath it, and zinc-plated Coat Hook rated around 11 kg on the side and back panels. A riveted Number Plate and a door-face Card Holder handle allocation.

Below, the choice of base follows the floor regime. Dry corridors get a closed Plinth Base that seals out debris; wet changing rooms get a bolt-on Leg Set of 150 mm legs so the floor hoses clean underneath. Leveling Foot adjusters plumb the carcass — an out-of-plumb locker is the usual cause of latches that will not engage — and Anchor Bracket fixings tie the bank to the wall, because a child climbing an unanchored locker bank is the product's classic tipping hazard.

Finish

Corrosion protection is a phosphate-plus-powder system. Panels pass through a Phosphate Pretreatment wash that deposits an iron- or zinc-phosphate conversion layer, then receive an electrostatic polyester Powder Coat cured at 180–200 °C to a 60–80 µm film. The phosphate layer is what slows rust creep under the film when the inevitable scratch happens; the Touch-Up Kit kit exists to seal those scratches before they bloom. Two-tone schemes — neutral body, colored doors — are standard because doors and bodies are coated in separate batches anyway.
