A channel bar is a long, heavy-duty, U-shaped piece of steel or iron that is used for structural support in construction, engineering, and other industries: 

Channel bar

Description

A long, rolled bar with a U-shape and flanges on either side that form right angles

Uses

Structural foundation, skeletal support, roof trusses, wall assemblies, ceiling anatomy, bridge decks, railings, and stair stringers

Advantages

Versatile, compatible with various surfaces, and designed to be long-lasting

Channel bars are also known as heavy-duty purlins. 

Channel bars are important because they provide structural support and stability to buildings and other structures: 

• Support
  Channel bars are used as a building's skeleton, providing the major support for its structure and foundation. They can be used in a variety of ways, including for walls, roofs, floors, and ceilings. 

• Durability
  Channel bars are strong and durable, and can withstand heavy loads. They are also resistant to corrosion, rust, and degradation. 

• Versatility
  Channel bars can be customized to meet specific project requirements. They can be cut, drilled, and shaped into different sizes and lengths. 

• Fire resistance
  Channel bars can withstand high temperatures for longer than other materials like wood or aluminum. 

• Cost-effective
  Channel bars require minimal maintenance and replacement, making them a cost-effective choice. 

Channel bars are typically made of rolled steel or iron and have a U-shaped form. They are also known as heavy duty purlins because they are used for large constructions.
