Material only proves itself after years

Why marine-grade aluminium?

Most outdoor kitchens look excellent on the day they are installed. Once your kitchen stands outdoors, however, it will meet conditions you are unlikely to be thinking about on installation day: rain, UV radiation, frost, temperature swings, perhaps salt-laden air.

So an outdoor cabinet body should not be judged by how it looks when new, but by how it has been engineered.

A consistent choice of material, not a special feature

Marine-grade aluminium

The PureAlu cabinet body of your FREILUFT Kitchen is made from solid 8 mm marine-grade aluminium. The alloy is highly corrosion-resistant and is also proven in shipbuilding.

We deliberately use stress-relieved precision material. It is particularly dimensionally stable and designed to hold its dimensions reliably under changing external conditions.

Over many years an outdoor kitchen is exposed again and again to temperature swings, heat, cold and moisture. What matters, therefore, is how well the whole construction stays under control over the long term.

Every opening is a point of exposure

As few penetrations as possible

Look inside a FREILUFT cabinet body and you will not find universal rows of holes. Every penetration serves a specific purpose.

The more closed the construction remains, the fewer points of exposure there are for moisture and other external influences. We therefore place openings only where the engineering genuinely requires them.

Pre-treatment decides the outcome, not the shade

Off-Shore powder coating

The colour of your kitchen should not only convince on the first day. The aluminium therefore receives a powder coating built up for demanding outdoor use, with the corresponding pre-treatment.

  • Material: marine-grade aluminium, 8 mm
  • Pre-treatment: nano-ceramic
  • Coating: Off-Shore powder

The nano-ceramic protective layer is a step you cannot see on the finished piece — and whose absence you can see after a few winters.

A more important question than sealing

Water has to get out again

You will hardly be able to prevent moisture from finding its way into an outdoor construction at some point. So a different question matters more: how does it get out again?

The cabinet body is prepared for this too. The drawers are engineered to shed water, and an integrated drainage system carries moisture deliberately to the outside.

How these components work together as a system is shown by the PureAlu Cabinetry System. What rain, frost and salt-laden air actually do over the years is covered in the article on the weatherproof outdoor kitchen.

Questions about your project?

If this article has left any questions open, we are glad to answer them. A short conversation is often enough to clarify what is realistic in your outdoor space.
