MS C Channel is a type of steel section with a C-shaped cross-section. It is also known as a C Purlin, as it is commonly used to provide structural support for roofs and walls in pre-engineered metal buildings. MS C Channels are made from mild steel and are available in various sizes and thicknesses. MS C Channels are used as structural support for roofing and cladding sheets. They are typically installed horizontally between the rafters or trusses of a building, and are spaced at regular intervals. The roofing or cladding sheets are then fixed to the top flange of the C Channel using self-drilling screws or other fasteners.

MS C Channels are lightweight and easy to install, making them a popular choice for building construction. They are also cost-effective, as they can be fabricated in large quantities and are readily available in the market. MS C Channels are strong and durable, providing excellent structural support for the roof and walls of a building.
