Tredecim only manufactures from 100% recycled aluminium. This ecological process reuses waste aluminium materials and consumes only 5 percent of the energy needed to produce aluminium from ore. Our manufacturing process starts by smelting waste aluminium ingots in heat resistant crucibles and hand pouring the molten liquid into a series of sand moulds at a constant and continuous rate.

Left to cool and harden naturally these individual sand cast components are then carefully hand welded using aluminium solder to create a single solid piece of furniture with no nuts, bolts or fixings giving optimum strength and stability.

The furniture is then colour powder coated as a whole single piece so that there are no seams or joints on the exterior surface into which water could penetrate.
Finally the furniture is baked at 180 degrees centigrade to allow the powder colour to super adhere into the aluminium surface to create exceptional colour longevity.
