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.
