Which material is commonly used in corrosive environments?

• A. FRP
• B. Steel
• C. Wood
• D. Aluminum

Answer: (A)

In corrosive environments, you want a material that resists chemical attack rather than one that rusts or degrades quickly. FRP, or fiber-reinforced plastic, fits that need because its resin matrix is resistant to many acids, bases, and salts, and it doesn’t rust or corrode like metals. The fibers provide strength while the plastic matrix shields them from chemical exposure, so structures such as piping, tanks, and ductwork in chemical plants, wastewater treatment, and offshore applications stay intact longer with less maintenance. Metals like steel and aluminum can corrode when exposed to corrosive environments, and wood can deteriorate or rot, so FRP is commonly chosen for these conditions.
