What do the numbers on a beam mean?
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.
How do you read a wide flange beam size?
Wide flange beams are designated by the letter W followed by the nminal depth in inches and the weight in pounds per foot. Thus W12 × 19 designates a wide flange beam with a depth of 12 inches and a nominal weight of 19 pounds per foot.
What size is a W10x12?

| W10x12 | 12 | 9.87 |
| W10x15 | 15 | 9.99 |
| W10x17 | 17 | 10.11 |

What do the numbers mean on a steel beam?
The nomenclature for steel shapes follows two standards: For wide flange, bearing pile, S-shapes, channels, and tees: the letter indicates the shape, the first number indicates the nominal height, and the second number indicates the weight per 1 foot of length.
What does a 12 foot steel beam weigh?
“I”-Beam – Standard
| Designation Depth in inches x weight Per Ft. Lbs | Weight Per Ft. (Lbs.) | Depth Section (inches) |
|---|---|---|
| S12 x (12×5) | 31.8 | 12 |
| 35.0 | 12 | |
| S12 x (12×5-1/4) | 40.8 | 12 |
| 50.0 | 12 |
What is a wide flange?
Wide Flange beams have flanges that are nearly perpendicular to the web of the material, unlike the traditional I-Beam. Wide Flange can be found in many structural applications such as bridges and buildings.
What is the standard size of beam?
THE STANDARD SIZE OF THE BEAMS In a residential building it is 9 ʺ × 12 ʺ or 225 mm × 300 mm standard size according to (IS codes). The minimum RCC beam size should not be less than 9 ʺ × 9 ʺ or 225mm × 225mm with the addition of a 125mm slab thickness.
What does W21x44 mean?
When a beam size begins with “W,” it means the beam’s flanges are not equal to the thickness of the web. 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 does W10x22 mean?
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).

What does WT stand for in structural steel?
Tee Beams split from Wide Flange Beams are designated as “WT” preceding the size (stem height X weight/foot X length).
