Fiberglass rods are primarily made from glass fibers, which are woven together and then coated with a resin to form a solid, durable rod. This unique composition provides an array of benefits, making fiberglass rods suitable for various applications. Unlike traditional materials like steel or wood, fiberglass is lightweight, making it easier to handle and install. Additionally, it does not corrode, which extends its lifespan and reduces maintenance costs for infrastructure and equipment.
