Flange thickness shall be measured at the half way point

Squareness of section is determined as the sum deviation from 90° of both flanges

Where tolerance bands overlap, the greater value is applied

About this product

Hot rolled channel, commonly referred to as parallel flange channels, taper flange channels and U channel is a versatile low cost, low carbon product suitable for a wide variety of applications. The product is mainly used flat in the U orientation or vertically against another structure (wall/steelwork) giving maximum support to the section to help prevent twisting away from the web. The section is sometimes used in the construction industry, however universal beams and columns feature more frequently in building design due to a higher efficiency of carrying bending and shear loads.

European standard sections (UPN and UPE) are also available to us in the UK but are not commonly specified by designers and architects. UPN and UPE sections are also more expensive when compared with UK channels even when both standards are imported. S275 and S355 specifications are easily fabricated and machined without the need for high-performance tooling. Both specifications have a similar chemical makeup and specifications will sometimes overlap. For S355 material to meet the required standard a minimum tensile yield strength of 355 N/mm² must be achieved, however, the minimum yield value reduces as the material thickness increases.

The outside of the bar in the AR (as rolled) condition in both spec’s has a blue/grey coloured finish, this is known as the surface scale and can be removed by pickling and oiling (P&O) or various abrasives including shot blasting. Channels are not generally used for the manufacture of small parts with construction and many varied engineered and fabricated products being the main use. For this reason, the P&O process is not generally used, shot blasting and primer painting and hot dip galvanising the preferred methods of corrosion protection.

Channels are manufactured in the same rolling process that produces all hot rolled long products but unlike flats, squares and rounds etc. PFC’s due to their end use are rolled in a range of standard sizes, 6 and 12 metre lengths are stocked on site with 9.5, 11 and 14 metre lengths also available.

A greater number of hot rolling section tolerances apply to channels due to the relative complexity of the profile when compared to round or square bars. Tolerances fall within the limitations of the hot rolling process and intended end use requirements of the section.
