Longer-lasting with better performance and miles more economical.
SteelFlow™ is a sustainable, high-performance, durable asphalt consisting of 95% steel slag aggregates combined with a Polymer-Modified Binder (PMB). It can be laid ultrathin, allowing budgets to go further, and it also reduces noise pollution and increases skid resistance.
Less is more
As budgets come under increasing pressure, SteelFlow is welcomed by councils and local authorities that strive to meet the challenge of maintaining safe and serviceable roads within the constraints of tighter budgets.
Goes the extra mile
With the durability, strength and skid-resistance associated with SteelPhalt products made from steel slag aggregate, SteelFlow also uses modified bitumen which gives the material greater flexibility and elasticity. SteelFlow can be laid at a depth of just 15mm, resulting in faster installation times, reduced labour and greater surfacing areas for the same volume of product.
Proven performance
SteelFlow shows excellent skid resistance figures above the investigation level in SteelPhalt’s grip testing program, especially through the summer months.
Like many of SteelPhalt’s other products, SteelFlow contains a high percentage of recycled materials at 95%. This gives SteelFlow added appeal to suppliers who wish to meet sustainability criteria.
Performance statistics
In a recent case study, one of our customers was looking to cover a section of highway spanning 785 meters. The plan was to use a traditional 14mm dense surface course laid at a depth of 40mm.
We recommended that they consider using SteelFlow as an alternative solution, laid at 15mm depth.
By using SteelFlow material, 59% less asphalt would be required to surface the job saving 46% on material costs.

Application opportunity
The Humber Bridge's surface is a dual carriageway designed to tolerate constant motion and bends of more than three meters in winds of up to 80 miles per hour.
Recommended product
Due to the complexity of the requirements, 6 SteelFlow was the ideal material choice for this application.
Results and benefits
The material has been monitored as part of our in-house Grip Test programme. Installed in 2017, SteelFlow continues to maintain its SCRIM values.
