Strut Channel Roll Forming Machines

Strut channel roll forming machines are used to form metal coil into C-shaped strut channels, which have a wide variety of structural applications. This comprehensive guide provides an overview of strut channel roll former equipment, including types, components, specifications, and suppliers. It also covers key considerations for application, installation, operation and maintenance.

Overview of Strut Channel Roll Forming Equipment

Strut channel roll forming machines take flat metal coil stock and form it into U-shaped or C-shaped channels through a series of bending and forming rollers. The continuous channels produced are used for structural framing, supports, braces and studs in construction, racks, scaffolding, trailers, greenhouses, solar panel mounting and more.

Key benefits of using a strut channel roll former include:

  • Highly customizable and adjustable channel dimensions
  • Efficient, automated production of continuous channel lengths
  • Consistent quality and structural strength of formed channels
  • Versatile for small, medium or large production requirements
  • Cost-effective compared to other forming methods

Strut channel profiles are available in various sizes like 1-5/8”, 2”, 2-1/2″, 3″, 4″, 6″ as per application needs. Common materials used are low carbon steel, galvanized steel and stainless steel in gauges from 16 gauge to 11 gauge.
