The seat/tree grille ALCORQUE ROUND is made in steel, 40/10 thickness, polyester powder coated (or corten, treated with a particular oxidation process). The steel sheets are welded together through a continuous welding, later polished.
The structure is made of 2 halves matched and fixed with 4 screws M8 to be inserted on the side. Under the seat there are strong support profiles, 40/10 thickness.
On the base of each half there are 4 holes, 12 mm diam., for the fixing to the ground through specific bolts (not provided).
Steel EN10111DD11 is used for the realization of this product and all the elements in this material, after all the different stages (cutting, bending, welding), are treated with electrogalvanizing according to the UNI regulations and are later polyester powder-coated with RAL colours at choice.
As an alternative to steel EN10111DD11, the production in corten is also available, on demand. In this case the material is treated with a specific oxidation process.
