Chemical CompositionA36 is a low carbon steel. Low carbon steels are classified by having less than 0.3% carbon by weight. This allows A36 steel to be easily machined, welded, and formed, making it extremely useful as a general-purpose steel.

Thanks to the 90-degree bend, angle iron is extremely strong along its length, and resists bending. It can easily support larger loads than similar thicknesses of flat steel and it is much stronger than wood or many composites pound for pound.
Steel Angles are the most basic type of roll-formed steel. They are formed by bending a single angle in a piece of steel. Angle Steel is 'L' shaped; the most common type of Steel Angles are at a 90 degree angle. The legs of the “L” can be equal or unequal in length.
Manufacturers typically make C channels in a range of standardized sizes, but they will build you a customized piece if necessary. The manufacturing process is quite fast, as long a wide piece of metal is usually cut by a machine before entering a symmetrical press where the walls are flanged into shape.
The Different Types of Structural Steel and Their Uses in
- Structural Steel.
- Parallel Flange Channels.
- Tapered Flange Beams.
- Universal Beam.
- Universal Column.
- Angled Sections.
- Circular Hollow Sections.
- Rectangular Hollow Sections.
While a bit more expensive, c-channel is significantly more rugged in most applications than equivalent quality angle iron.
The most efficient shape for both directions in 2D is a box (a square shell) however the most efficient shape for bending in any direction is a cylindrical shell or tube. But, for unidirectional bending, the I or wide flange beam is superior.
The shape of I beams makes them excellent for unidirectional bending parallel to the web. The horizontal flanges resist the bending movement, while the web resists the shear stress. They can take various types of loads and shear stresses without buckling.
Steel I-Beam CostA steel I-beam costs $6 to $18 per foot for just the materials. Steel support beams for residential construction costs $100 to $400 per foot to install or between $1,200 and $4,200. Extra costs apply for knocking down walls, rerouting utilities, or adding underpinnings for support.
You would need to provide specific sizes for the I beam vs. Channel question but in general a channel is one half of an I beam that is split down the vertical rib so yes, the I beam is stronger.
I beam is the most efficient shape for one direction bending. If you turn that I beam 90degs basically into an H beam, it would be less strong than a square beam. I beam will also be worse than square tube in torsional loading. Torsional loads need a member with a closed cross sectional area.
Tubing is unidirectional, where as C channel has strength in one direction. Allowing the metal to be thicker and weld stronger. The tubing is thinner walled all the way around and the welded areas are weaker. Your strength on the tongue is 90% downward.
Sections Parallel Flange Channels
It is also known that the stiffness and strength of a C-channel can be increased by forming a small lip on the free edge of each of the flanges. Such lips are formed by rolling or otherwise turning the edges of the flanges toward one another such that the lips extend generally perpendicular to the flanges.

The “W” indicates that it is a wide flange beam (as opposed to, say, an S beam); the “14” is referenced as section number; and the “211” indicates that the beam weighs 211 lbs per foot. You should note that the permissible variations from the specified dimensions can range from 1/8in to 5/16 depending on the beam size.
Standard lengths vary from 6m up to 18m. Mild steel sheets and plates are essentially flat material rolled into specific sizes and thickness.

How to Order Steel Beams
- Locate the beam you wish to order on your steel drawing plans and turn to the general instructions at the front of your building plans.
- Note down on your piece of paper the type of flange of the beam.
- Note the measurements of the flange.
- Write down the weight per foot of the beam.
H beam is a structural beam made of rolled steel. H-beam has wider flanges than I-beam, but I-beam has tapered edges. The width is the flange and the height is the web. The difference between the H and I beams is the flange per band ratio.

A channel is a passageway, a means of access for a thing, a communication, or an idea. Think of a channel as sort of a tunnel or a funnel that moves something directly through. The noun channel can be used for many such avenues.
In the United States, steel I-beams are commonly specified using the depth and weight of the beam. For example, a "W10x22" beam is approximately 10 in (25 cm) in depth (nominal height of the I-beam from the outer face of one flange to the outer face of the other flange) and weighs 22 lb/ft (33 kg/m).
Also known as heavy duty purlins, channel bars are recognizable as a long rolled bar forming a hard U shape – the flanges creating right angles on both sides. Its smaller variation is more commonly used for frame supports in automobiles.
Most of the time when I think of “web channel” it means the web as a channel of doing something. For example in marketing we often break campaigns into web / tv / radio. On the other hand a website is part of your web channel strategy while you may have apps for your mobile strategy.
