Steel fibers

Structural Fibers

General description

The structural steel fibers can 100% replace the classical rebars or the welded mesh in any ground-level constructions.

They are the most used and known type of reinforcement fibers in the world, as they are far more time and cost efficient than the classical armature.

Steel fibers advantages:

  • Cost;
  • Disperse structural reinforcement - Which means reinforcing each cubic centimeter of concrete;
  • Transport - The amount of steel or steel mesh are reduced;
  • Time – The reinforcement is done by simply mixing the fibers in the concrete;
  • Improved physical characteristics:
    • Reduces plastic contraction;
    • Reduces the thermal contraction and expansion of hardened concrete;
    • Improves the impact strength and compression resistance;
    • Helps achieving a homogeneous ductile concrete, increases its elasticity and, as final result, increases bearing in concrete elements;
    • Reduces the possibility of forming cracks;
    • Increases the wear-proofness of the floor;
    • Increases floor resistance even at temperature changes and thermal shocks.

 

Application example:

  • Industrial flooring;
  • Highways paving;
  • Airport runways;
  • Earthquake resistant structures;
  • Maritime structures;
  • Lining tunnels;
  • And other ground-level constructions.

 

Transport and storage of steel fibers

  • The shipping is done only by weatherproof transport means;
  • The packing will be on pallets of 1 ton. Each pallet is being wrapped in stretch film;
  • The storage has to be done in covered spaces, protecting the product from any atmospheric factors that might degrade the packaging;
  • For handling the wooden pallets, the staff has to be instructed in order to avoid the deterioration of the stretch film or the paper bags.

 

Mixing and homogenization

Mixing and homogenization can be achieved either at the concrete station or directly in the truck mixer in 5 to 7 minutes at high speed.

 

Packing

Metallic fibers are packed in laminated paper bags of 20 kg.

Fibers are slowly starting to replace the classical reinforcement made with steel bars or welded mesh.
For example, steel fibers provide with lower costs for labor and smaller prices per project, due to their quality and the small product amount needed to get a strong and safe disperse reinforcement.
Romfracht produces several types of fibers, with three main applications:

  • Fibers for disperse reinforcement - FORTA FERRO and STEEL FIBERS (they replace steel bars and welded mesh);
  • Fibers for screeds (for reinforcement and thermal control): SUPER NET, ECONO NET, ULTRA NET (These can completely replace the welded mesh for screeds ranging from 1 cm to 10 cm);
  • Fibers that eliminate the microscopic cracks in any type of concrete: RAWWHITE fibers. These fibers are excellent for use with plasters. It is highly recommended that you use these fibers with reinforcement fibers or screed fibers.
