Dramix® steel fiber concrete reinforcement

Dramix® steel fiber concrete reinforcement
Your choice of concrete reinforcement has an important impact on the quality, safety and longevity of your structures. Using the right reinforcement compensates the low strain capacity of concrete and it helps controlling cracks. Dramix® steel fiber concrete reinforcement offers an efficient and versatile solution.

Smart and proven technology

Choosing the right type of reinforcement for your structural concrete elements is essential to guarantee the strength and safety of your structure. Concrete has low tensile strength and ductility and adding reinforcement is necessary to resist stresses and strains in structural members. Steel fiber reinforcement provides superior resistance to cracking and crack propagation under any type of load by compensating these shortcomings.

World leading institutes such as the ACI and ASCE recommend using steel fiber as supplementary material in reinforced concrete to prevent cracking, improve impact resistance and prevent damage.

The reference in steel fiber reinforcement

Dramix® is the pioneer and world leader in steel fiber reinforced concrete:

  • Each year, more than 30 million m² of concrete floors are being reinforced with Dramix® steel fibers.
  • Across the globe, every hour, one thousand trucks of Dramix® steel fiber reinforced concrete leave the batching plant.
  • Bekaert produces on  average 180 kilotons Dramix® steel fibers, per year.

The perfect solution for a smooth finish and long-lasting performance

Dramix® steel fiber reinforcement features unique hooked ends, high tensile strength and ductility. This results in previously unavailable levels of anchorage and crack control, creating more durable and safer buildings. Since introducing Dramix® in the early 70s, Bekaert has built up considerable know-how in steel fiber reinforcement and has continuously invested in research and development, and worked on all aspects of the fibers, including shapes, l/d ratios, coatings, usage, dosing equipment, and applications.

In many cases, Bekaert worked in close cooperation with academic institutions and clients. As a result, Dramix® has been approved by international regulators:

  • In 2007, Dramix® became the first steel fiber to obtain CE marking Class 1 for structural use
  • Since 2010, all Dramix® plants have been ISO 14001 certified.

Over the years, Dramix® has inspired architects to invent new ways of expressing themselves with concrete and realize some of their most creative and visionary works – without compromising safety, cost-efficiency, or durability.

Smarter fibers for more durable concrete

For concrete to be durable, it needs to be both strong and ductile. This is exactly what Bekaert aims for with its Dramix® series. Depending on your specific application specific need, we can propose you the right fiber: 3D, 4D or 5D. Each fiber in its respect balances wire properties (shape, strength, ductility, length/diameter ratio) and combines it with strong anchorage. Moreover, you can choose between bright and galvanized. And to avoid fiber-balling during mixing and to ensure an evenly spread throughout them concrete mix Bekaert can provide them in glued bundles as well.

  • Dramix® 3D: These fibers remain widely recognized as the best solution when it comes to performance and cost-efficiency. They allow quick installation and provide a long service-life.
  • Dramix® 4D: These fibers are specifically designed to provide optimal crack control for concrete structures.
  • Dramix® 5D: Thanks to their unique shape and capabilities, these fibers provide performance levels which until now could only be realized with traditional reinforcement.
