What are MC Channels?

MC channels, also called ship or miscellaneous channels, have flanges that are generally thicker than their webs, and thus have higher static values. The tolerances for MC channels are in accordance with ASTM A6. Unlike C channels, the inner faces of MC channels’ flanges are parallel, which makes them easier to assemble. Common applications for MC channels include nonresidential building construction, stairs, foundations, and other architectural uses.

At Service Steel Warehouse, we have locations throughout the Gulf Coast and Midwest which means our team can get you the MC channels you need, quickly and competitively priced. Fill out this form or call our team directly to get a fast and free quote for your next project.

Benefits of MC Channels

MC channels offer several benefits and are a popular choice in various industries. The top advantages include:

  • Easy to fabricate and customize to project requirements.
  • Made from high-strength steel to provide structural support.
  • Able to be coated or galvanized to increase resistance to corrosion.
  • Less prone to degradation making MC channels cost-effective in the long term.

MC Channel Applications

MC channels are extremely versatile and due to their structural support qualities have many applications. Examples include:


MC channels are an abbreviation for miscellaneous channels, which are usually made from carbon steel. “Miscellaneous” designation indicates that these channels do not conform to the standard dimensions of other channel types, such as C or U channels.

C channels have tapered flanges, meaning that the flanges’ inside surfaces aren’t parallel. MC channels have parallel flanges that are flat and not sloped, making them easier to assemble or bolt because no spacer washers are needed to create a flat bolt surface inside the “C”.

MC channels have many uses but their flat flanges and the high strength of steel make them great for architectural applications such as structural supports and stairs. In addition, they’re also commonly used in tractor-trailers, car frames, ships, and more.

Measuring steel MC channels is done by determining its:

  • Depth (D)
  • Flange width (B)
  • Flange thickness (T)
  • Web thickness (TW)
  • Root radius (R) (if applicable) 

Additionally, the dimensions are usually specified in inches. For example, an MC 12 x 50 would weigh 50 pounds per foot, have a depth of 12 inches, a flange width of 4.135 inches, and varying specific thicknesses for the flanges and web dependent on the weight. See our full channel sizing chart here.

MC channels prices can vary widely based on size, rendered services, market conditions, and other factors.
