What is Composite Rebar and why is it better than metal
Construction technologies are developing rapidly, which is why new construction materials have started to be actively used. For example, the traditional use of metal has given way to composite materials

Composite rebar — non-metallic rods made of glass, basalt, carbon or aramid fibers impregnated with thermosetting or thermoplastic polymer binder. Special ribs are formed on the surface of Composite Rebar or sand coating is applied during production process in order to bond with concrete
Properties of Composite Rebar
Not afraid of chemical attack and moisture, that affects the durability of the materials usage and the possibility of their application at any time of the year
Corrosion and chemical resistance
Tensile strength of composite rods and mesh is 3 times higher than its steel counterpart
Tensile strength
Does not conduct electricity or interfere with cell phone and internet signal propagation
Dielectric, no radio interference
Does not form thermal bridges — this improves the thermal insulation parameters of the construction object
Low thermal conductivity
Even at severe frosts composite rebar does not lose its properties. Temperature threshold of operation ranges from -70°C to +100°C
Heat resistance
Lack of welding simplifies installation — any worker with a minimum set of tools can handle the binding of rebar
Easy to install
Poor corrosion resistance of composite reinforcement can lead to rapid deterioration of building structures and accidents
Can not be used for prestressing
GOST 31938-2022 requires the reduction in tensile strength of composite reinforcement after exposure to an alkaline environment to be no more than 25%. In case of anhydride hardener based reinforcement, this figure is more than 50%
Subject to corrosion
Anhydride Hardeners
MOST MANUFACTURERS USE
Composite reinforcement made using amine hardeners is more alkali resistant and is also prone to elongation
Allowed to be used for prestressing
Amine Hardeners
WE USE
Tests of composite reinforcement on amine hardeners for alkali resistance show a strength drop of 11% on average, with individual samples showing less than 3% strength drop
Protected against corrosion
Why do we use amine hardeners
Currently, most manufacturers use anhydride hardeners as a binder in the production of Composite Fiberglass Rebar

We use amine hardeners exclusively, which provide higher physical and mechanical characteristics of the cured systems, excellent water- and alkali-resistance, as well as significantly higher resistance to elevated temperatures
We are confident in the quality of our products because we comply with all legal requirements for composite building materials. You can also make sure of this by ordering our samples with delivery

More advantages of Composite over Metal
Cost savings in materials
Composite rebar is cheaper than metal rebar, and its high strength allows it to replace steel analogs with a larger diameter
Reduced transportation costs
Due to the compact shape of the package, transportation of such rebar is much easier — one can use the trunk of any car
Expansion coefficient like concrete's
There is no imbalance in the reaction between concrete and composite rebar caused by temperature changes — this protects concrete structures from cracking
Low specific weight
Having low weight, composite rebar does not create unnecessary loads on the main elements of the building — it can be used where it is impossible to use metal rebar
Energy efficiency
The heating costs of a building constructed using composites are lower compared to steel rebar constructed buildings
Waste-free use
Rebar flexibility allows to eliminate the amount of waste that is inevitably present when using metal rebar
