What is junior beam construction?
Standard American Beams. Also known as Junior Beams, S Beam, or I Beams have tapered flanges for increased strength of the flanges. Wide Flange Steel Beams - Also known as W Beams or H Beams have non-tapered flanges that are wider than the standard S or I beams.
What do beam sizes mean?
The number associated with the pile (i.e. W21) indicates that the flanges are 21 inches long. The second number (i.e. W21x44) indicates the weight per foot of the beam. So in this example, a wide flange beam that is W21x44 has two flanges that are each 21 inches long and a weight of 44 pounds per foot.
What are the different I beam sizes?

What is half an I beam called?
Parallel flange channels (PFC) - otherwise known as C channels, they effectively shape half of an I beam.
What are 3 types of beams?
Types of beam structureContinuous beams. A continuous beam is one that has two or more supports that reinforce the beam. ... Simply supported beams. Simply supported beams are those that have supports at both end of the beam. ... Fixed beams. ... Overhanging beams. ... Cantilever beam.
What are the 6 types of beams?
The different types of beamsUniversal beam. We also commonly refer to a universal beam as an I-beam, and it is one of the most frequently used beams in steel structures. ... Hip beam. ... Trussed beam. ... Lattice beam. ... Composite beam. ... Chilled beam. ... Reinforced concrete beam. ... Steel beam.More items...•
Which is stronger H or I-beam?
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 comparison, the cross section of an I beam can bear direct load and tensile but cannot resist twisting because the cross section is so narrow. This means that it can only bear force in one direction.
What is stronger I-beam or T-beam?
Abbas Khan Civil Engineer 1- T beams have greater second moment of inertia as compared to the ordinary beams, so they have greater ability to resist bending effectively. The distribution of the material mass in the T-beam is consist of Flanges and web.
What shape of beam is strongest?
There are several shapes that are used when strength is important. The arc (think: circle) is the strongest structural shape, and in nature, the sphere is the strongest 3-d shape. The reason being is that stress is distributed equally along the arc instead of concentrating at any one point.
What is the difference between I-beam and I-beam?
The flanges resist bending while the web takes on the shear force. An I-beam has tapered flanges with a narrower flange than most wide flange beams, making it a lighter building material. A wide flange beam, with wider flanges and web than the I-beam, can handle more weight, but this makes it heavier overall.
What is the smallest I-beam?
We also offer I-beams in a variety of web and flange thicknesses, from 0.114″ to 1.060″.
What does the i stand for in I-beam?
Two horizontal planes, known as flanges which are connected by one vertical component, make up an I-beam, as the shape of the connection creates an uppercase “I” in the cross section.
How do you read a beam size?
In Canada and the United States, steel I-beams are commonly specified using the depth (in inches) and weight of the beam (in pounds per foot). For example, a “4 x 13” I-beam is approximately 4 inches in depth (the measurement taken from the outer face of the first flange, to the outer face of the opposite flange).

What do w beam numbers mean?
wide flange beamThe “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.
What is the beam size for 2 3 and 4 storey building?
Beam size for 1 storey, 2 Storey, 3 Storey, 4 storey, & 5 storey building. Minimum RCC beam size should not be less than 9″x 9″ (230MM X 230MM), with an additional slab thickness of 125 MM.
