Introduction

A stainless steel structural channel (also stainless steel C section or stainless steel U section) is a hot rolled stainless steel channel offering a corrosion resistant stainless steel channel solution for load‑bearing and framing applications. Available in standard grades including 304 stainless steel channel, 316 stainless steel channel, 316L stainless steel channel, and duplex stainless steel channel, these channels combine high strength‑to‑weight ratio with excellent durability in aggressive environments. The C‑shaped profile (parallel or tapered flanges) provides efficient resistance to bending and shear forces.

Classification

1.Channel steel is divided into ordinary channel steel and light channel steel.

2.According to shape:

(1)Cold-formed equal-edge channel steel

(2)Cold-formed unequal-edge channel steel

(3)Cold-formed inner curled channel steel

(4)Cold-formed outer curled channel steel

Fundamental State

In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billets for producing channel steel are carbon steel or low alloy steel billets with a carbon content of no more than 0.25%. The finishedchannel steel is delivered in a hot-formed, normalized or hot-rolled state.

The specifications are expressed in millimeters of height(h) width(b) thickness(d). For channel steel with the same height, if there are several different widths and thicknesses, a,b,c must be added to the right of the model number to distinguish them, such as 25#a 25#b 25#c, etc.

Specifications

The specifications of channel steel are mainly expressed by height(h),width(b),thickness(d) and other dimensions. The specifications of domesticchannel steel range from 5-40, that is, the corresponding height is 5-40cm. At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. No.18 to 40 are large channel steels, and No.5 to 16 are medium channel steels.

The delivery length of channel steel is divided into two types: fixed length and double length, and the tolerance value is specified in the corresponding standard. The length selection range of domestic channel steel is divided into three types according to different specifications:5-12m,5-19m,and 6-19m.The length selection range of imported channel steel is generally 6-15m.

Applications

(1)Construction – Stainless steel channel for construction (building frames, mezzanine floors, handrail posts, curtain wall supports) delivers long‑term structural integrity without painting or coating, reducing lifecycle maintenance.

(2)Structural support – Stainless steel channel for structural support (equipment skids, platform framing, crane rails, conveyor supports) offers high load capacity and corrosion resistance in indoor or sheltered environments, with 304 grade for general service.

(3)Framing – Stainless steel channel for framing (solar panel mounting structures, machinery bases, racking systems, modular enclosures) provides precise dimensional tolerances and weldability, with 316L grade for coastal or chemical plant exposure.

(4)Industrial use – Stainless steel channel for industrial use (food processing facility framing, pharmaceutical clean‑room supports, chemical plant walkways) resists frequent washdowns, sanitizing agents, and corrosive spills, with duplex grade offering higher strength for heavy loads.

(5)Marine – Stainless steel channel for marine (boat trailer frames, dock gangways, shipboard supports, offshore platform handrails) withstands salt spray and seawater splash, with duplex or 316L grades providing superior chloride pitting resistance.
