Megasteel is the largest stockholder and distributor of steel for the prestressing and post-tensioning of concrete in the UK. We specialise in the distribution of steel for the prestressing of concrete, and while our products disappear into concrete and are never seen again, they are vital in providing prestressed concrete with its strength.
We are not owned by a steel mill, and act as an entirely independent steel supplier. We are very proud of our reputation in the industry as a highly dependable, straightforward and long term business partner.
Indented prestressing wire to BS5896:2012 and all other leading international standards.
Plain and indented strand to BS5896:2012 and all other leading international standards.
In addition to Wire and Strand we also supply our own unique design of strand dispenser and other products including specialist meshes.

At Megasteel, we have spent the last six years working on a simple question: Can prestressing wire be made more consistent? Not stronger. Not different in specification. Just more reliable in performance.
Why This Matters
In prestressing applications: Performance is governed by the weakest wire, not the average strength. Even when all material meets the same standard, variation within the product can affect reliability. Reducing that variation has been the focus of our work.
The CRX™ Project
Over the past six years, we have been working with our manufacturing partners to develop a chromium-modified more consistent prestress in wire. This material — now referred to as CRX™ — has been designed to:
- Improve consistency of microstructure
- Reduce sensitivity to normal process variation
- Deliver more stable mechanical properties
CRX™ is not designed to increase strength — it is designed to reduce variation and improve consistency of performance.
What the Data Shows
We have recently reviewed production mill test certificates for both conventional and CRX™ material. From this initial analysis:
- Average strength is the same
- However, variation is significantly reduced
Typical observations:
~30% reduction in variation (5mm)-
~40–45% reduction in variation (7 mm)
What This Means in Practice
Lower variation results in:
- Fewer low-strength outliers
- More predictable stressing behaviour
- Greater confidence in installed material More consistent wire leads to more reliable structures.
Ongoing Work
This is an initial assessment based on current production data. We are now expanding the data set further to: - Increase sample size- Confirm statistical trends- Better understand minimum performance levels
Final Thought
After six years of development of CRX™, the message is clear: reducing variation is one of the most effective ways to improve reliability in prestressing. A more controlled product is, ultimately, a more consistent product.
All Wire is manufactured to BS5896:2012 or any other internationally recognized standard.
Coil Weight and Dimensions – Wire is usually supplied in coil weights of approx. 2.3T. Strand is usually supplied in coil weights of approx. 3T.
Other coil weights are available on request.
All material is supplied wrapped unless otherwise requested.
The modulus of elasticity may be taken as 205 kN/mm2 for wire and 195 kN.mm2 for strand
The permitted deviation on weight per metre is +/- 2%
With over 30 years experience we have a unique understanding of the use of pre-stressing wire and strand. We are happy to share this experience with our customers. If you need any help or advice just ask.
We have developed our own unique design of strand dispenser which helps to prevent
tangling of strand during dispensing. Please ask for more detail.
We also supply special wire mesh and other steel products for the use in construction. If you have any special requirements, please ask us!
