Product Description 

Steel U bars are perfect for domestic or commercial use. Many of our customers use these U-shaped bars to reinforce concrete, but there are many other uses. They make great fixing post inserts and structural supports. 

When U bars are used in concrete, they stop it from slipping under pressure. They also increase the already immense load-bearing capacity of concrete, creating an overall stronger, sturdier structure. 

All our steel comes from UK-based mills. Once we have sourced the steel, we take it to our in-house manufacturing plant and cold roll it into place. 

Shape Code 13 Explained

This code refers to a U-shaped rebar with a semi-circular bend that has a gap. 

Shape Code 21 Explained

This code refers to a U-shaped rebar without a circular gap at the bend.

We can manufacture Shape Code 13 and Shape Code 21 steel bars in any length, diameter, and quantity.

Grade B500B Explained

Our U bar steel products are incredibly versatile. This bar is Grade B500B, so it is designed to reinforce other structures. The tensile/yield strength is 500 N/mm2, making it one of the most heavy-duty rebars on the market.

We stock off-the-shelf U bar steel in these sizes.
