Acrylic Bathtub VS Fiberglass Bathtub. Both fiberglass bathtub and acrylic bathtub are the two most common bathtubs in the market. They are both molded plastic bathtubs. Acrylic bathtub has fiberglass in it, and fiberglass bathtub is made from more than just fiberglass.
Cold-formed steel (CFS) is the common term for products made by rolling or pressing steel into semi-finished or finished goods at relatively low temperatures (cold working).
Cold water temperatures, about 35 degrees Fahrenheit, caused the steel to crack in a brittle manner, like glass, when it hit the Iceberg, instead of the ductile, twisting, tearing manner, we are all accustomed.
