Stainless Steel Channel Beams (C Channels)

Stainless steel channels—also referred to as C channels—feature a distinct squared C shape formed from a flat piece of stainless steel. These structural components are available in tapered and non-tapered variations in a wide range of sizes, thicknesses, and materials to suit different applications.

Although lighter and more flexible than I-beams and other structural steel materials, C channels offer greater rigidity than flat steel and higher strength than angle iron. They typically find use in construction and civil engineering projects as supporting structures for walls, roofs, window and door frames, automotive frames, and trailers.

At Stainless Shapes, Inc., we offer a broad selection of stainless steel channels. Available in 304, 316, and 2205 duplex stainless steel for greater tensile strength and resistance to corrosion, our channels come in an assortment of sizes to meet the specifications of a wide range of customer projects.

Stainless Steel Channel From Stainless Shapes

Our stainless steel C channels feature a symmetrical design and demonstrate superior durability and reliability in structural applications. Regardless of whether they are hot rolled or laser fused, they are available with the following specifications:

Channel Materials

We offer C channels in 304/304L, 316/316L, and 2205 duplex stainless steel grades.

304/304L Duplex Grade Stainless Steel

Due to its high formability, strength, and corrosion resistance, 304 grade stainless steel is the most commonly used stainless steel on the market. Both 304 and 304L (the low carbon variation) are austenitic alloys, meaning they have higher chromium and nickel contents than other stainless steel alloys. The higher chromium content increases the material’s corrosion resistance, making it particularly suitable for use in food and beverage production, medical and pharmaceutical industries, and chemical manufacturing and transport.

The qualities of 304 and 304L stainless steel—i.e., strength and corrosion resistance—make them excellent options for the manufacture of channels for structural supports. In addition, 304L’s low carbon content increases its weldability, making it easier to form into C channels and, later, I-beams.

316/316L Duplex Grade Stainless Steel

Although less frequently than 304 stainless steel, 316 stainless steel still finds use in many
structural and industrial applications. In addition to the standard iron and chromium contents, 316 also contains molybdenum. These additional elements reduce the material’s susceptibility to corrosion from salt and other chlorides, making it an ideal choice for use in supports for offshore facilities and marine applications, as well as food processing, pharmaceutical, textile manufacturing, and other corrosive environments. Similar to 304L, 316L (its low carbon variation) is easier to weld.

2205 Duplex Grade Stainless Steel

2205 stainless steel is a steel alloy that demonstrates both ferritic and austenitic characteristics. This combination of qualities results in a material with greater strength, durability, and resistance to corrosion and stress cracking than standard austenitic grades. Additionally, for thicker workpieces, it maintains good weldability. Available in a variety of forms—including bar, plate, sheet, and tube—it suits use in chemical processing, pulp and paper manufacturing, marine, mining, oil and gas, and heat exchange applications.

In addition to these three grades, we also use customer grades upon request if the project meets a set minimum mill order.

Channel Sizes

Our C channels range in size from C3 x 4.1 to C15 x 50.

Channel Industry Standards

Our stainless steel channels meet all applicable industry standards, including:

  • For hot rolled channels: ASME SA479, ASTM A276, ASTM A484, and ASTM A479 (dimensional tolerances)
  • For laser fused channels: ASTM A1069 and ASTM A1069M – 11 (production) and ASTM A276, ASTM A484, and ASTM A479/A479M (dimensional tolerances and grades)
