Composite rebars and mesh

Composite rebars and mesh provide more than 2 times higher tensile strength in comparison with the steel rebar of the same diameter, thus strengthening concrete for decades. They are 7 times lighter than their metal analogues. These properties significantly reduce the transportation costs, speeding up and simplifying the activities at a construction site.

They are not subject to corrosion and appear as an ideal solution for reinforcement in environments exposed to water, salt and humidity. Their service life is more than 100 years, which is a more durable solution compared to metal reinforcement and mesh. Safety and convenience. Unlike steel, composite material can be easily cut with a hand tool. As not forming sparks, it excludes fire occurrence at the construction site.

Unlike metal analogues, composite reinforcing products (rebars and mesh) are not subject to plastic deformations and retain their shape even after special equipment passes over them. This greatly simplifies the reinforcement works at horizontal areas, allowing the equipment to maneuver along the construction site.

Deformation resistance. Composite rebars and mesh are not subject to plastic deformation and do not have shape memory. Due to these unique properties, they can be stored and transported as round coils and rolls with very long lengths. This may greatly speed up the reinforcement process at the facility and saves space in warehouses.

Composites are a step towards ecology. The composite material of rebars and mesh is an excellent heat insulator compared to metal counterparts, and does not create cold (heat) bridges. This can significantly save on the energy consumption of the building. In addition, manufacturing of 1 kg of composite material consumes 9 times less electricity than the production of 1 kg of steel. By using our products you help to reduce CO2 emissions into the atmosphere.

They do not conduct electricity and are diamagnetic. These properties allow the use of composite products without fearing high voltage currents and magnetic fields - for example, during the construction of the subway or MRT rooms.

Composite rebars synchronize with concrete – this means that the coefficient of linear thermal expansion of fiberglass rebars and mesh coincides with that of concrete. Therefore, temperature fluctuations and thermal stresses do not influence the structures, and they last longer. The manufacturing technology of composite rebars allows varying the parameters of the periodic profile and exceeding the adhesion strength of metal reinforcement to concrete. Due to its special elastic properties, the composite material does not cause problems during shrinkage of high-strength concrete classes, and in special prestressed structures it retains tensile forces better.

One of the problems with layered composite materials is the transfer of shear forces between layers. That is why the internal fibers of the rebar (especially of large diameter) are not so actively involved in power work - the load from the outer layers is not transferred properly to the inner ones, and while the outer fibers are already stretched to the limit, the inner ones work at 50-90 % of their capabilities. The exact value depends on the diameter and length of the rebar. To increase the rebar efficiency, we make the additional prestretch of its internal fibers, thus increasing rigidity and robustness.
