Quality & materials

What goes into our lockers

Good lockers come down to the material, the finish, and the hardware. This is exactly what goes into ours, in steel and in wood, and what we can adjust for your project.

Where we go further

Thickness with nothing hidden

The thickness we quote is the bare steel before paint, not a figure inflated by the coating, and on our full-height lockers it runs through every part, not only the door.

Glides that protect floors

Legless cabinets sit on smooth glide feet, so they can be slid into position without scratching the floor or the cabinet base.

Honest advice on what's possible

We're straight about thickness and capacity. Where a requested steel thickness is not suitable for our locker construction, we will say so and suggest a medium-duty shelving option instead.

Steel

The body is cold-rolled DC01 steel to EN 10130, Turkish in origin. Standard thickness is 0.70 mm, with 0.50, 0.60, or 0.90 mm available where the size and capacity of a model allow it. The figure we quote is the bare steel, measured before paint.

Typical elongation (A80)~31%
Mill certificatesEN 10204, on request

The thickness we quote is used on every part, not only the door. We don't thin the back or shelves to cut cost.

Wood

Alongside steel, we build wood lockers and cabinets, mostly office and staff file cabinets and teachers' wardrobes. These are made to order, so the internal layout is set to the job rather than to a fixed model.

BoardChipboard, melamine-faced chipboard, MDF, or MDFlam
Body, shelves, doors18 mm
Back panel8 mm
Edge banding0.80 mm standard, with 0.40, 1, or 2 mm on request
FinishMelamine (MDFlam), lacquer, or paint
Standard decorsMaple, white, oak, walnut, with the closest available match for other colors
HingesStandard, anti-pinch, or piano, for child safety
Feet5 cm adjustable feet as standard, with longer feet, a legless base, or wooden feet on request
OriginMade in Turkey

Common builds include a full-height cabinet with shelves behind a door, a lower lockable section under open shelving, glass or plexiglass door panels, and a hanging-rail wardrobe for staff. The shelf count is set to the job and is not capped, so if you need seven or eight shelves we build seven or eight. A tall cabinet at only 36 cm deep can tip, so anti-tip hardware is standard on the 185 cm height. A wall bracket that holds the unit to the wall is available on request. So are rounded corners and plywood. Wood lockers carry the same 2-year warranty as our steel range.

Finish and color

On steel lockers, after the surface is cleaned and any weld marks are smoothed, parts get a powder coat at a standard film thickness of 60 to 80 microns. We use a powder coating that holds Qualicoat and GSB approvals, is UV-resistant, and non-yellowing, and you can choose a gloss or matte finish. Wood lockers are finished in melamine, lacquer, or paint, covered under Wood above.

The antibacterial powder coat is tested to JIS Z 2801, the international test for antibacterial surfaces, with a measured activity value above 2.0. It is available on request, on steel lockers, and is not the standard coating. It suits changing rooms, gyms, clinics, and other high-contact settings.

Steel locker parts on the powder-coating line, before the curing oven

On steel, twelve standard RAL colors are kept ready, and any other RAL is available on request as part of our custom and OEM work.

Locks and hardware

Every locker comes with a padlock hasp as standard, so you can fit your own padlock. We also offer key (cam) locks and electronic locking with a PIN, RFID card, or fingerprint. Locking can be single-point or three-point, and if you'd rather use your own lock we'll cut the opening to match it.

Certifications and documentation

Our quality management is certified to ISO 9001:2015. For the applicable locker models we can provide product compliance documentation, along with steel mill certificates (EN 10204) and coating certificates, on request. The mill certificate covers the steel batch used on your order, so the material can be traced back to the mill. See Export & logistics for the full document set.
