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 rolled steel is essentially hot rolled steel that has been processed further. Cold rolled steel is often used to describe a range of finishing processesâthough, technically, cold rolled applies only to sheets that undergo compression between rollers. Things like bars or tubes are drawn, not rolled.
