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).
Hot rolled steel is steel that has been roll-pressed at very high temperaturesâover 1,700ËF, which is above the re-crystallization temperature for most steels. This makes the steel easier to form and also results in products that are easier to work with.
