Placement
The Kortu is equipped with a loose base plate with 4 mounting holes. These holes have a diameter of 12 mm and are 20 cm apart. You attach the base plate to a concrete base (available at a DIY store). Then place the letterbox over it and screw it to the sides with bolts. The final bolts are included.
Corten steel
Corten steel is a very strong type of steel that will cover itself with a protective layer of rust when exposed to the outside air. This rust layer provides protection against further corrosion. Characteristic of Corten steel is its brown-orange rust color and its long lifespan.
Rust process
Corten steel is a very strong type of steel that covers itself with a protective layer of rust when exposed to the outside air. The letterbox is always delivered unrusted and gets its beautiful rust color/layer when it is outside. This process takes approximately 6 to 12 months. This process can be accelerated to 2 weeks by using the rust accelerator. The rust accelerator can be found at the bottom of this page under smart combinations.
After it is completely rusted, we always recommend applying a rust fixer. This ensures that the rust process stops and no rust water will come off the letterbox. The rust fixer can also be found at the bottom of this page under smart combinations.
