Composite reinforcement ROCKBAR

Intended use

ROCKBAR is designed for reinforcement of prestressed and non-prestressed construction structures and components.
ROCKBAR are manufactured by pultrusion, in which basalt fibers are impregnated with a polymer binder, and then run through the system drain bushing.

Design

Composite rebars ROCKBAR are basalt or glass fiber bars of a round section, cut to length, sand coated or plain.

Out company has realized the following construction projects using composite armature ROCKBAR: The Thompsons Bridge in the Northern Ireland, area of the highway Europe-Western China in the Republic of Tatarstan and others.
  • Composite armature ROCKBAR
  • Composite armature Rockbar GFRP
  • Composite armature Rockbar BFRP
  • Composite armature Rockbar BFRP

Advantages of composites

  • Absolute corrosion resistance, alkali resistance;
  • High strength;
  • Low weight;
  • Absolute eco-friendliness and fire safety;
  • Durability;
  • Dielectric;
  • Non-magnetic;
  • Low thermal conductivity.
Application of composite rebars ROCKBAR increases constructions life time and time between repairs.
