Storage boxes are designed to disappear. Stacked, labelled, pushed to the back of a shelf. This one is designed to be looked at, which changes every decision about how it is made.

RDF-0004 is two pieces of 5 mm sheet aluminum, each folded up from a single blank. A deep base and a shallow lid that sits over it. There is no hinge, no catch and no fastener anywhere in it — the lid lifts off and sets back down, and the fit is held by the geometry rather than by hardware.

That is the part that does not photograph and has to be handled to be understood: at 5 mm, the lid is heavier than the box under it, and it lands with a weight that no sheet-metal or plastic box can produce. Every wall you see is 5 mm of solid material, top edge included.

Nothing is applied to it. No lining, no felt, no veneer — the interior is the same folded aluminum as the exterior, because covering it would mean hiding the only material in the object.

It ships raw as standard. No coating, no lacquer, no film — the surface you see is mill-finish aluminum, as it comes off the roll and out of the brake, and it will darken and even out with handling. If you would rather it stayed exactly as it arrived, powder coating in any RAL colour is available at no extra charge.

Manufactured in Zagreb to our own drawing. The alloy specification, tolerances and finish are ours — which means custom sizes, custom colours and project quantities are quoted from the same drawing rather than sourced from someone else's catalogue.

Material & durability
Aluminium–magnesium alloy, EN AW-5754
H111 Magnesium is the principal alloying element in the 5000 series, and it is what gives the alloy corrosion resistance in humid air without any surface treatment at all. This is why these pieces can be supplied raw and why uncoated aluminium does not behave like uncoated steel: the oxide film forms in seconds, it is self-repairing, and scratching through it simply starts the process again. The practical consequence is that there is no finish to fail. Nothing chips, nothing peels, and no cut or folded edge is more vulnerable than any other part of the surface.
One material, full section
The failure mode of the category is delamination. A laminate face over a particleboard core has an edge that must be sealed with a separate material, and moisture at that seam lifts the band and swells the core. Everything in this line is cut and folded from a single sheet — one material through the full section, with every visible edge a radiused fold of the same stock. There is nothing applied and nothing that can come off.
Surface variation
Mill-finish aluminium carries roll lines and handling marks, and sheen varies between faces and between pieces. This is inherent to raw material and is not a defect. If you require a uniform surface, order the piece powder coated.
Powder coating
Polyester powder coat in any RAL colour, no additional charge. Cured after fabrication, so the film is continuous across folds and no cut edge is left uncoated. Coated pieces are suitable for covered outdoor use; raw pieces are indoor only.
Suitability
Suitable for use Covered outdoor
Care & cleaning
Routine cleaning
Wipe with a soft cloth, warm water and a pH-neutral detergent, then dry the surface. Raw aluminium shows fingerprints and water marks more readily than a coated surface — cosmetic, and it evens out as the patina develops.
Do not use
Strongly alkaline cleaners, including caustic soda and oven cleaners. These etch aluminium and the damage is permanent. Also avoid strong acids, chlorine bleach and abrasive powders.
Restoring the surface
Unlike a coating, a raw surface can be worked. Scratches and uneven patina come out with a fine abrasive pad worked in one consistent direction, then wiped clean. Work the full face rather than the mark alone, or the repair will be more visible than the damage. Patina The surface darkens slightly and evens out over the first months of use, faster in handled areas. This is the oxide layer building and it protects the metal. Leave it or take it back — both are fine.
If powder coated
Neutral detergent only, no abrasives, no solvents. Touch up any chip promptly with a coating matched to the original RAL reference.

FAQ
  1. Does the lid stay on?
    It sits over the base with a small clearance on each side and is held by its own weigh. There is no catch, so it is not a sealed or lockable box. Lift it straight up rather than sliding it.
  2. What fits inside?
    Correspondence, cables, a watch roll, cosmetics, small tools, one pair of shoes. It is a single-volume box with no dividers
  3. Is the inside lined?
    No. The interior is the same raw folded aluminum as the exterior. It is unlined by intention — this is a decorative object rather than a jewellery case, and lining it would mean covering the only material in it. If you are storing something soft or polished, add a cloth or a felt insert.
    Will it mark what I keep in it?
    Aluminum is softer than steel and harder than most things you would put in a box. Leather, fabric and paper are unaffected. Anything with a polished or lacquered finish should not be left loose inside — the same is true of any unlined metal container.
    Will it scratch the surface it sits on?
    Self-adhesive felt pads are supplied for the underside and should be fitted before use. Bare aluminum on a wooden or lacquered surface will mark it.
    Can it be stacked?
    No. The lid is flat but there is nothing locating one box on top of another. It is designed to sit on its own.
    Can I get it in another size?
    Yes. Both parts fold up from a single blank each, so the size is a parameter rather than a redesign. Taller, wider or a shallower lid — quoted on request.
