Lip channels, also known as C channels or C purlins, are hot-rolled mild steel or galvanised “C” shaped steel with inside radius corners that are widely used in general fabrication, manufacturing and structural applications. The C-shape configuration of a lip channel provides superior strength and structural support when the load of a project is horizontal or vertical. The shape of a lip channel or C purlin also makes it easy to cut, weld, form and machine.
Uses of lip channel or C purlin include manufacturing, general fabrication, construction, industrial maintenance, heavy machinery, agricultural implements, transportation equipment, automotive industry and structural support applications.
Two of the most utilized grades of lip channels or C purlins are EN 10025 S275 and Z275. EN 10025 S275 is a popular mild steel grade suitable for various use in engineering and general construction applications. Having low carbon steel specifications, EN 10025 S275 provides great machinability and excellent weldability, despite limited strength. Mild steel grade S275 is widely used in the construction, maintenance and manufacturing industries.
Grade Z275 is another popular choice for hot-dipped galvanised structural steels, where mild steel grade S275 is being hot-dipped galvanised with a zinc coating of 275 g/m2. Z275 has excellent welding properties and is suitable for different kinds of applications, including welding, bending and fabricating. Its resistance to rust and weathering elements makes Z275 galvanised steel an excellent base material for all construction and structural buildings. Depending on the thickness and corrosion resistance of the alloy, hot-dipped galvanised Z275 is versatile with good formability and can be machined and formed using a variety of processes.
