Zinc Coated Steel Sub-Structure
The Zinc Coated Steel Sub-Structure used in Coleman Spas® units has
the highest strength to weight ratio of any building material
available. The light-gauge steel frame provides greater structural
integrity than wood as well as superior corrosion protection for a
much longer life. Unlike wood, steel is dimensionally stable. It will
not expand or contract with moisture, which over time can damage the
spa's exterior. Sturdy and built to last, the inorganic properties
will never rot, warp, split or crack and eliminate worries of animal
infestation or termite damage. Stronger, more durable and ideal for
the environment - it's the obvious choice for a lifetime of worry-free
fun.
