The SKY030 spiral staircase, available in 3
diameters — 47, 55 and 63 in. — is manufactured in
steel with a particular treatment (Sendzimir process)
that consists in galvanizing steel by using a small
amount of aluminum in the zinc bath and producing a
coating with essentially no iron-zinc alloy. This process
guarantees high resistance and durability. In addition
the metal is powder coated. The final result is a staircase that is specifically made for outdoor installations
because of its resistance to atmospheric elements.
