Our Structural Steel Types

Structural steel is one of the most versatile and most used buildings material on earth. Engineers and builders have used structural steel to accomplish feats that we would have thought impossible. Gigantic skyscrapers, bridges that stretch for miles, and much much more. All designed to last for hundreds of years.

To grasp the full potential of structural steel, you must understand its various shapes, sizes and potential uses. Here is an overview of the types of steel we offer at Neil’s Steels.

Universal Beam

254 X 146 X 31KG Universal Beam

The Universal Beam (UB), also known as an I-beam, is a beam that has a cross-section shaped like an I. The “sides” are known as flanges and the joining element is termed the web. Universal beams are usually made of structural steel and are used in construction and civil engineering.

We also offer Universal Beams in a few variations: Twinned CHS (Circular Hollow Section), Twinned PFC (Parallel Flange Channel), Twinned Joined, and Welded Flat Bar.

Universal Column

152 X 152 X 23KG Universal Column

Universal Columns (UC) are very similar to Universal Beams, however the flanges are wider, allowing them to carry more weight.

We offer Universal Columns in the same variations as the above Universal Beams.

Mild Steel Channel

Mild Steel Channels are commonly used in the building trade, often as a lintel above doors or supports to floor joists. Steel channels can be easily cut, drilled or machines and are particularly well suited to welding. To increase corrosion resistance, mild steel is normally painted or galvanised after fabrication.

We can also provide Mild Steel Channels in Twinned CHS and Twinned Joined variants as well.

Mild Steel Flat Bar

Mild Steel Flat Bar is a cost-effective and remarkably versatile form of steel which is suited to a huge range of applications. Although it displays the superb combination of strength, versatility and formability of steel, the reduced carbon content of mild steel makes it easier to work and therefore great for fabrication and construction purposes (as structural steel).

In addition to its malleability, mild steel is also highly recyclable and can be reworked once used. Our Mild Steel Flat Bar can be easily cut, drilled and welded; it is a superb choice of material for constructing frames, trailers and many more high strength structures in domestic, commercial and industrial environments.

Mild Steel Equal Angle

I don’t think we need to comment on the versatility of this type of steel again. So, I will just say that our Mild Steel Equal Angle structural steel has many practical uses, including the construction of fences or trailers, and is often used as fence posts.

See above but with an unequal angle!

Circular Hollow Section

Circular Hollow Section 26.9 x 3.0

Circular Hollow Sections, also known as round steel tubes, are a common type of steel section that is used in a variety of formats over various industries. Most commonly available are hot and cold rolled Circular Hollow Sections. Hot rolled sections are predominantly used for structural purposes while tubes rolled from cold rolled steel has better bending ability and gives a better aesthetic appearance after being powder coated.

Square/Rectangular Hollow Section

See above but with a square or rectangular shape. This has a couple of benefits: square and rectangular steel tubes have the advantage of being stronger in bending while a round hollow sections has more stiffness in twisting.

And that is all of the different types of structural steel we offer! We hope you found this useful, either as an outsider to the industry, a novice or someone looking for alternatives to the standard universal beam. Keep us in mind if you are ever looking for structural steel! If you’re looking for more metalwork, marine or welding, check out our sister site, J. Colburn.
