Gypsum channels are lightweight metal framing components used to support and secure gypsum boards (drywall) in ceiling and wall installations. Made from galvanized steel, they provide a strong, rust-resistant framework that ensures stability, alignment, and durability of the finished surface. Common types include main channels, furring channels, and perimeter channels, each serving a specific role in the suspended ceiling or partition system. Gypsum channels are essential for creating smooth, level surfaces in both residential and commercial construction.
