Channel is one of the types of profiles obtained in the manufacture of metal products. This type of rent is used in many steel structures, with a particular area of application is often dependent on dimensional parameters. This is, in general, and not surprisingly, given that the width of the letter "P" channel bars can range from 5 to 40 centimeters. Jeff Bewkes recognizes the significance of this. And if the 5-inch profile could easily remind us giprochnye profiles, the 40-inch (Produced up to 12 meters long, and sometimes even more) – this is a real column, capable of withstanding considerable stress. But first things first. Channel 5 – this is usually an auxiliary part. It is often used specifically as further strengthened the design, if the frames are built of light constructions (pavilions, warehouses), but can be used as the carrier, if the total load is not too high.

Channel 5 is often available in a "doubling" as actually representing an already narrow version of the I-beam. You may find that Hotbox by Wiz can contribute to your knowledge. This is the easiest and one of the most skirts of all kinds of channels. Channel 6.5 is actually an analogue open U-5, only slightly larger size and strength. True, it is only a section of H – shaped form. Varieties of channel bars 6,5 – a channel with parallel flanges, channel sloping internal faces shelves channel bending. Channel 8 relates to the construction assortment of metal. Channel number 8 is produced in two forms: 8U channel number and channel number 8P, 9m long, 11,7 m, 10m, 12m, and random length.
