BENDING METAL C(U)-CHANNEL

The horizontal bending of channel iron is a hard-way, and the bending method is as difficult as the H-beam. It requires a special BIT section bending machine with a ninth hydraulic component.

channel steel

Channels with longer legs take on a U shape, and so are called steel U channels or U section steel channels. They are virtually the same as a typical steel c section; only the longer leg length gives the steel u-channel its alphabetical namesake.

The channel is often used for columns, and lintels above doors to give support to floor joists. If you are using a channel as a lintel it will need a bottom plate added to it to take the outer bricks. Alternatively, two channels could be fixed back to back to support both leafs of a cavity wall.

Structural steel channels are hot rolled products that have a C-shaped cross section. They consist of two legs connected by a web.

Channels are featured in tank stiffeners, tank supports, roof beams, circular platforms and fabricated trusses.

Depending upon your unique project requirements, Profile Bending angle bending may be performed on a variety of materials, including carbon steelstainless steelaluminumtitanium, and copper.

Important things about steel channels

Here are some important things about structural steel channels that you should keep in mind when looking at them:

The ‘depth’ of the channel (how tall it is)
Leg height
The thickness of the leg
The thickness of the web
The fillet of the C-channel. The fillet is the angle where the leg meets with the web. This radius is not always provided

How to bending u(c) channel

BIT series channel bending machine profile bending machine ability to bend both standard channels (designated as C channel) as well as miscellaneous channels (designated as MC channel), from the very small sizes to the very large sizes. In fact, profile bending machine can bend all of the mill supplied sizes of all types of channel.

Section bending machine can ability to bend channel the easy way (against the weak axis) and the hard way (against the strong axis).It can bend all types of channel including aluminum, stainless and carbon steel.

Standard channel and miscellaneous channel are specified in similar fashions. An example callout for standard channel would be C12x20.7#. The C indicates standard channel. The 12 (in inches) indicates the depth of the channel. The 20.7# indicates the pounds per foot for the channel.

Similar to wide flange and I-beam, channel can be bent with a number of different bending processes. The most common bending method is a roll bend or pyramid bends method. Straight material is inserted into the rolls; the rolls are then moved horizontally to put the desired radius into the material. The material can also be bent incrementally hot or incrementally cold. This is where small sections of material are bent at one time. When finished the section has a smooth curve to the bent section. Finally channel can also be bent in a plate roll which is typically done when bending stair stringers.

Just like wide flange and I-beam, to successfully bend channel the hard way one must use a web stretcher and/or mandrels. These tools are critical to use when bending the hard way as they keep the critical web from buckling or distorting.

types of steel channel

There are various types of steel channel categories:

Structural channels, which are common in construction and manufacturing
Ship and car channels, specific for those industries
Stair casting channels, for constructing stairs
Bar channels, these are usually much smaller than typical C-channels, for specific uses
Like with structural beams, these structural steel channels have lots of different names.

They can sometimes be referred to as ‘hot rolled parallel flange channels’ or just ‘flange channels’, or ‘channel beams’, or ‘PFC sections’ in addition to just being referred to as a C shape steel beam.

Application

Bending aliminum U-channel

One of the most common usages of bent channel is for stair cases. The bent channels act as the stair stringers (link to specialty bending: spiral, circular & helical bending) (supports) and are bent helically. Bent channels are also used in light structural applications like awnings and car ports typically found in residential buildings or light commercial structures.

How to choose a u-channel bending machine

Two-minute review

U-profile

The U-profile is a simple semi-finished product. It is characterised by its open design and high transverse stability. This gives this long material a particularly wide range of uses.

Properties of the U-profile

The U-profile is one of the standard profiles. It offers a higher transverse stability than the L- or the flat profile. This makes it suitable for high-strength welded constructions with demanding statics. Once firmly integrated into a construction, U-profiles can be loaded from practically all sides. Its semi-open design is particularly interesting. This makes it suitable for use as a channel or as an easily accessible channel for cables, hoses and pipes. It does not offer the protection of a completely closed pipe. However, it can easily be extended with a cover so that the elements inserted or liquids passed through are fully protected.

Materials for the U-profile

The versatility of the U-profile continues in its unpretentiousness when it comes to its materials. Unlike window profiles, for example, the choice of materials for U-profiles is not limited.

Common materials for this long material are as follows:

  • Plastic
  • Sheet steel
  • Aluminium
  • Composite materials such as GRP or CFRP are also processed into U-profiles. Even ceramic materials or artificial stone such as concrete or brick are available in short profiles in U-shape.

Manufacture of the U-profile

U-profiles made of plastic or aluminium are extruded. For this purpose, a pre-material – for example plastic granulate or aluminium blocks – is heated and pressed through a die. The profile is cooled down behind the die. This creates an endless strand that is simply cut off at the desired length.Steel profiles in U-shape are edged from thin sheet or continuously cast. The continuous casting variant is considerably thicker-walled, heavier and more stable.
