Hot-rolled and bent channel correspond to this type of metal product. Channel is a metal product with  P(П)- type cross-section. Channel is mostly produced  from metal slabs through mills. Channels are separated into the following categories:

Hot-rolled steel channels.

This type of channel is produced according to GOST 535-88 with parallel flanges and sloping flanges: 10, 10P and etc. The slope of inner flanges must not exceed 10%.

Assortment of the steel hot-rolled channel corresponds to GOS 8240-89.

The number of the channel corresponds to its size (distance between the inner flanges) expressed in cm. For example: Channel #10 - distance between the inner flanges equals 10cm. All other parameters: flange width, wall thickness and etc. according to GOST (shown in the GOST catalogue).

Channel that has letter A at the end of the number (14A) is a channel with sloping inner flanges, it means the flanges are wider and hence the weight of each meter is larger than ordinary channel.

There are special types of hot-rolled channel:

special channel for automotive industry - GOST 19425-74 (18S, 20S);

special channel for wagon production - GOST 5267.1-90 (8W, 14W, 18W).

Bent steel channel (equal and non-equal flanges):

Steel bent channels (profiled bent channel) is produced according to GOST 11474-76 on channel profiling machines from cold-rolled and hot-rolled steel of ordinary, carbon and high quality constructional or low alloyed steel.

Channel assortment corresponds to:

equal flanges - GOST 8278-89;

non-equal flanges - GOST 8281-80.

The numbers of such type of channels correspond to its size, represented in mm.

For example: 40x32x2.5, where 40 - in the distance between the flanges (mm), 32- width of the       flange (mm), 2.5 - wall thickness (mm).

Bent angle differs from rolled angle by rounded sides, judged by visual inspection.
