Galvanized strapping/banding is the better choice, and likely will cost less than stainless anyway.

A galvanic cell will form and the zinc will react faster in sacrifice to iron and other metals of the stainless steel alloy.The insulation material must be a non-conductive one. Or the fixing material should be made of the same material as the fixed one, for example, galvanized steel banding for fixing galvanized insulation cladding.
