What is stronger C channel or I-beam?
The C-beam maintains strength tolerances at a lower gauge than the I-beam, which results in thinner, lighter components. If you've never worked with C-beam profiles before, keep reading.
H beams are easier to weld than I beams because the outer flanges are straight. The cross section of the H beam is stronger than the cross section of the I beam, meaning it can bear a greater load.
In the vertical direction (as oriented for the beam profile chart image above), C-Channel is typically stronger for the weight than tube. That makes it attractive, but it doesn't come in as many different sizes, thicknesses or varieties. Finally, the open section means you can easily finish it all over.
H-Beams. One of the strongest steel beams on the list, H-beams, is made up of horizontal elements, while the vertical beams act as the web. The flanges and web create a cross-section that mimics the shape of the letter “H” and are popular in construction or civil engineering projects.
The structural channel, also known as a C-channel or Parallel Flange Channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering.
A box beam that is solid in construction and made of acrylics or aluminum will be more durable overall than an I-Beam, as the extra, solid material makes it more difficult to bend, crack, twist or break over time.
“H-beam is a stronger design when bending stress is considered,” Davis said. “H-beam rods are more difficult to machine, so they are often more expensive. I-beam rods are easier to produce and can sometimes be lighter than H-beams. All other variables being equal, H-beam rods are the strongest design.”

---|---|---|
Single Channel | 8" @ 11.5 # | 10800 |
Single Channel | 9" @ 13.4 # | 14000 |
Single Channel | 10" @ 15.3 # | 17900 |
Double Channel | 4" @ 5.4 # | 5080 |
C-channel. While a bit more expensive, c-channel is significantly more rugged in most applications than equivalent quality angle iron. In projects where either is viable without introducing issues of expense or simple engineering headaches, many will prefer c-channel.
A C channel the same weight as tubing has more metal on one side allowing that side to be welded correctly. 2 inch C will weld stronger in all applications then the tubing you have shown. What weld would be stronger.
Why is an I beam stronger than a solid beam?
The design of an I beam makes it capable of bending under high stress instead of buckling. As the beam receives the load, the force is transmitted perpendicularly, thus supporting other members of the beams. I beams are mostly made of steel, therefore ensuring structural integrity with relentless strength and support.
I beams are usually the critical support trusses in structural steel construction. I beams are almost always used in the construction of large structures, such as warehouses and large buildings.

If your beam design is governed by yielding in bending (not lateral-torsional buckling/plate buckling, etc) then you need to increase the second moment of area (I) to increase the bending capacity. Usually this is done by fastening additional plates to the beam, typically onto the flanges.
C channels are one of the more common types of metal channels and are widely used in construction as building, wall, roof, and ceiling supports. The term C channel encompasses a wide variety of channel types, dimensions, and sizes since sheet metal can be roll formed to fit any specific requirements.
Here are some disadvantages of this building material: They increase internal forces on columns. They increase lateral forces on supporting beams. They add complexity to the design and require specialized professionals to ensure they're used properly.
Rectangular tube isn't any stronger than an I for the same top and bottom flange or tube wall thicknesses, but its prettier. Usually costs several times as much as I beams because its harder to make.
As per general thumb rule, for 30 feet span size of steel beam or universal beam or w beam or I beam or UB's or hot rolled section or Rolled steel joist (RSJ) should be ISMB 450 or UB 450×180 or W18 used for residential building or projects.
STEEL vs ALUMINUM vs TITANIUM Connecting Rods - YouTube
What is the best connecting rod?
If you're trying to make a lot of boost, an I-beam connecting rod is the best choice. When you need to lighten up the rotating assembly the H-beam connecting rod should be at the top of your list. These rods are a better fit for a naturally-aspirated engine where you're turning a high level of rpm.
For normal driving, torque loads and engine speeds, the rods will usually last well over 150,000 miles with no problems (assuming the oil is changed regularly and there are no lubrication issues). But in a modified engine that makes more power and spins at higher RPMs, powder rods won't hold up.

A six-inch purlin can span 18 feet.
Normally a spacing of C purlin is around 900mm (0.9m), 1200mm (1.2m) and 1500mm (1.5m). This can be spaced 1.2 metres apart when using sheeting with a thickness of 0.7mm, and 1 metre when using 0.5mm sheeting. Exact requirements will vary, but as a rough guide, this is a good rule of thumb to follow.
Round tube is about the strongest shape by weight. It's more resistant to both bending and torsion (twisting) than square or rectangular tubing of the same weight, chemical composition, production method, and roughly same dimensions.
Pipe Strength
In general, stainless steel piping is the strongest of the two.
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.
Rectangular tube isn't any stronger than an I for the same top and bottom flange or tube wall thicknesses, but its prettier. Usually costs several times as much as I beams because its harder to make.

What is the main disadvantage of I beam?
Here are some disadvantages of this building material: They increase internal forces on columns. They increase lateral forces on supporting beams. They add complexity to the design and require specialized professionals to ensure they're used properly.
H-beam: The H-beam looks like one piece of metal but it has a bevel where three pieces of metal come together. I-beam: An I-beam is not made by welding or riveting sheets of metal together and is only one piece of metal throughout.
