ASTM A36 C Channel Steel
Channel steel is a long strip of steel with a fluted section. It is a carbon structural steel for construction and machinery. It is a shaped steel with a complex section and its section shape is a fluted one. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.


Product details

ASTM A36 Steel Channel - Galvanized or Primed

ASTM A36 steel channel is hot-rolled, low carbon steel section with good properties including welding, machinability and ductility. A36 structural channel have two types of sizes: UPN & UPE - tapered flanges and parallel flanges respectively. If you can't find the specific size in the table below, bespoke channel dimensions are available.

ASTM A36 steel c channel

ASTM A36 mild steel channel could be galvanized or primed to add a layer of protective coating to resist environment or weather corrosion. The specific zinc coating can be ordered depending on your requirements.


  • Building or construction supporting components.
  • Framing supports for truck, trailer, equipment.
  • Ceiling channel system.
  • Everyday uses like worktable.
