Coil rods are a type of construction material that are commonly used in various applications. These rods are typically made of high-quality steel and are designed in a coiled shape, which allows for easy transportation and installation. Coil rods are often used in concrete formwork systems, where they are used to secure the formwork and provide stability during the pouring and curing process. They are also used in other construction projects, such as retaining walls, bridge abutments, and foundation systems. The versatility and durability of coil rods make them a popular choice in the construction industry.
