Universal Beams - FAQs

Below are the most common questions sent to our team about UB beams.

What is a universal beam?

A universal beam, also referred to as "UB steel" or "I-beam," is a structural steel component designed for strength and durability in construction projects. Its characteristic I-shaped cross-section features a vertical web and horizontal flanges, which provide excellent resistance under heavy loads.

UB steel beams are extensively used in constructing frameworks, floor supports, and load-bearing walls for both commercial and residential projects. Their robust design makes them a reliable choice for delivering stability and structural integrity in a wide range of applications.
What is the difference between RSJ and UB steel?
There are distinct differences in design and application between RSJ and UB steel components, in particular:
- RSJ steel beams feature a tapered flange design that was more common in older construction projects
- Universal steel beams feature a superior I-shaped cross-section with parallel flanges, providing greater strength and resistance to bending
Are universal steel beams hot rolled?

Yes, universal steel beams are typically manufactured using a hot rolling process. Hot rolling involves heating steel to a high temperature and shaping it through rolling mills.

This process allows the steel to be easily moulded into the precise I-beam shape, with parallel flanges and a vertical web, ensuring structural integrity and accurate dimensions.
Can a universal steel beam be used as a column?
Yes, a universal steel beam can be used as a column in construction projects, depending on the structural requirements.

It’s essential to consider the following factors when using UB steel as a column:
- Potential for buckling
- Load capacity
- Proper alignment
The I-shaped design of universal steel beams provides excellent vertical load-bearing capacity, making it suitable for supporting roofs, floors, and other structural elements in certain applications.
How to calculate UB steel sizes?
Calculating the size of a universal steel beam involves assessing several key factors, including:
- Load requirements
- Span length
- Type of structure being supported
The beam must be sized to handle the expected weight while maintaining structural integrity and meeting safety standards. Because these calculations require precise measurements and compliance of building regulations, it’s essential to consult a structural engineer.
Why are Universal Steel Beams Popular in Modern Construction?

Universal steel beams are a popular choice in modern construction due to their enhanced load-bearing capabilities. UB steel beams are ideal for frameworks, floor beams, and load-bearing walls. While RSJs may still be found in refurbishment projects or older structures, universal beams deliver higher performance and precision for both commercial and residential construction needs.
