I-Girder / NEBT Beams / Bulb Tee beam
I-girders are widely used in bridge construction and building projects due to their efficiency in supporting heavy loads over long spans. The have identical Top and bottom flange.
NEBT beams, also known as New England Bulb Tee Beams, are a variation of precast, prestressed concrete beams commonly used in bridge construction. They have a bulbous shape at the bottom of the beam, which provides additional strength and load-carrying capacity compared to traditional rectangular beams. NEBT beams are known for their efficient use of materials and ease of fabrication.
Bulb Tee beams are similar to NEBT beams in that they feature a bulbous shape at the bottom flange. This design provides increased stiffness and load-carrying capacity compared to standard tee beams. Bulb tee beams are often used in bridge construction and other applications where high strength and durability are required.
