A triangular keel roll forming machine, also known as a spring tee roll forming machine, is primarily used to produce high-quality triangular keel to support suspended ceiling solutions. These triangular keels are typically made of high-quality galvanized steel, offering excellent rust and corrosion resistance, making them particularly suitable for humid environments. Triangular keels are perfect for commercial and residential construction projects since their great strength and stability guarantee the durability of metal ceiling constructions and prevent sagging.
