Structural fiberglass is made through a process called pultrusion, which involves several key steps: 1. **Raw Materials**: The process begins with raw materials, primarily glass fibers and a resin matrix. Glass fibers are typically made from silica sand, limestone, and other minerals, which are melted and extruded into thin strands. 2. **Fiber Formation**: These glass fibers are drawn into continuous strands and wound onto spools. The fibers are then unwound and aligned in a specific orientation to provide the desired strength and structural properties. 3. **Resin Impregnation**: The aligned glass fibers are pulled through a resin bath where they are thoroughly impregnated with a thermosetting resin, such as polyester, vinyl ester, or epoxy. This resin acts as a binding agent, holding the fibers together and providing additional strength and rigidity. 4. **Preforming**: After impregnation, the resin-coated fibers are shaped into the desired profile using a series of forming guides and preformers. This step ensures that the fibers are properly aligned and the resin is evenly distributed. 5. **Curing**: The preformed material is then pulled through a heated die, where the resin cures and hardens. The heat and pressure applied in the die ensure that the material solidifies into a rigid, structural shape. 6. **Cutting and Finishing**: Once cured, the continuous length of structural fiberglass is cut to the desired length. The finished product may undergo additional finishing processes, such as sanding or coating, to enhance its appearance and performance. 7. **Quality Control**: Finally, the structural fiberglass is subjected to quality control tests to ensure it meets the required specifications and standards for strength, durability, and other properties. This process results in a lightweight, strong, and corrosion-resistant material suitable for various structural applications.

Yes, structural fiberglass is resistant to corrosion. Fiberglass, a composite material made from a polymer matrix reinforced with glass fibers, exhibits excellent resistance to a wide range of corrosive environments. This resistance is primarily due to the inert nature of the glass fibers and the chemical stability of the resin matrix, typically made from polyester, vinyl ester, or epoxy resins. The glass fibers themselves are non-reactive and do not corrode, unlike metals which can oxidize or rust when exposed to moisture and chemicals. The resin matrix acts as a protective barrier, preventing corrosive substances from reaching the fibers. This combination makes fiberglass highly suitable for applications in harsh environments, such as chemical processing plants, marine settings, and wastewater treatment facilities. Fiberglass structures can withstand exposure to saltwater, acids, alkalis, and various industrial chemicals without degrading.
