Steel junior beams are a standard structural material which its primary function is to carry loads transverse to its longitudinal axis (web). Steel junior beams are lighter in weight than standard I beams. Common applications within the construction industry.
What do beam sizes mean?
The wide flange beam (W shape) is a structural steel shape with I (or H) form. ... The designation of the wide flange beam gives information about the width and weight per unit length . For example W12 X 96 means 12 inches depth and 96 pounds per foot weight per unit length. Depth values are generally approximate.
Is an S beam the same as an I-beam?
In general speaking, I beams contains S-beam, universal beam , H beam or wide flange beam. However, these beam sections are different in dimensions, strength and applications. ... First, wide flange steel beam has parallel flanges while S-shaped I beam has tapered flanges which have a slope on the inside surface.
What is the standard length of a steel beam?
The standard range of hot-rolled I-beams includes beams with a height of 100-710 mm, flange width of 55-440 mm, web thickness of 3.8-100 mm and beam length of 4-12 m .
What is the purpose of an I-beam?
I beams are the choice shape for structural steel builds because of their high functionality. 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.
How do I know what size beam I need?
The distance across the center of the beam for which the irradiance (intensity) equals 1/e2 of the maximum irradiance (1/e2 = 0.135) is defined as the beam diameter. The spot size (w) of the beam is defined as the radial distance (radius) from the center point of maximum irradiance to the 1/e2 point.
How do you calculate beam size?
The formula for the section modulus is beam width times beam depth squared divided by 6 . A two 2-by-6 standard beam has actual dimensions of 1.5-by-5.5 inches which would give a section modulus of 1.5 x 5.5 x 5.5 / 6 = 7.6 which is not enough for this example. A 2-by-8 beam would be sufficient.
What are S beams commonly used for?
The American Standard S-Beam is a type of I-beam that resists bending and shear loads and is commonly used in construction, shipbuilding, and other industries . An S-beam has roughly the same profile as an I-beam, but instead of horizontal flanges, it has tapered flanges that slope away from the inside surface.
Is beam a weight?
| Size Weight in Kgs. Weight in Kgs. | 100 x 50 2.432 7.979 | 125 x 70 4.023 13.199 | 150 x 75 4.571 14.997 | 175 x 85 5.943 19.499 |

How much does a 12 inch I-beam weight per foot?

What size steel beam do I need to span 12 feet?
When it comes to residential projects like houses and smaller buildings, you can expect a steel beam to be eight inches wide . This allows it to span as much as 12 feet before you need another column.
What size steel beam do I need to span 24 feet?
For 24 foot span, size of simply supported beam for 2-3 storey residential building, using thumb rule, is about 15′′×18′′ in which beam width is 12′′ and beam depth is 15′′, if width will be kept 12′′, depth should increased, then beam size 12′′×24′′ can be used, providing with 4nos of 16mm bar at top, 4nos of 20mm bar at ...
What size steel beam do I need to span 30 feet?
If you have a 30-foot span, it is important to know just how long a beam you will need for support. There is a good rule of thumb for this: divide your span (in inches) by 20. So, if your span is 30 feet (or 360 inches) you would divide that by 20 to come to 18 feet .
What shape of beam is strongest?
The triangle is the strongest to as it holds it shape and has a base which is very strong a also has a strong support. The triangle is common in all sorts of building supports and trusses. The overall shape of many bridges is in the shape of a catenary curve.
Why is an I beam better than a solid beam?
Mass is far from the center. The most efficient shape is I beam. ... Due to the mass being farther from the center, I beams have a bigger moment of inertia .
What does W12x26 mean?
W12x26, for example means that d (depth) is approximately 12 inches and the beam weighs 12 pounds per lineal foot.
