What is composite reinforcement and how is it better than steel?
Construction technologies are actively developing, which is why new construction materials have been actively used. For example, the traditional use of metal has given way to composite materials

Composite reinforcement — non-metallic rods made of glass, basalt, carbon or aramid fibers impregnated with a thermosetting or thermoplastic polymer binder. For adhesion to concrete, special ribs are formed on the surface of the composite reinforcement during the production process or a sand coating is applied
Characteristic features of composite reinforcement
Corrosion and chemical resistance
No fear of chemical impact and moisture, which affects the durability of the use of materials, and the possibility of their use at any time of the year
The tensile strength of composite bars and mesh is 3 times higher than that of a steel similar products
Tensile strength
Does not form thermal bridges, which improves the thermal insulation parameters of the construction site
Low thermal conductivity
Even in severe frosts, composite reinforcement does not lose its properties. The temperature threshold for use ranges from -70°С to +100°С
Heat resistance
The lack of need for welding simplifies the installation - with wire-tying reinforcement, any worker can handle it with a minimum set of tools
Easy to install
Dielectric, no radio interference
Does not conduct electricity and does not interfere with the spread of the signal of mobile phones and the Internet
Why do we use amine hardeners
Currently, in the production of composite reinforcement, most manufacturers use anhydride hardeners as a binder

We use exclusively amine hardeners, because they provide higher physical and mechanical characteristics of the cured systems, excellent water resistance and alkali resistance, as well as significantly higher resistance to elevated temperatures
Protected from corrosion
Tests of composite reinforcement on amine hardeners to determine the resistance to alkalis show a drop in strength by an average of 11%, on individual samples less than 3%
WE USE
Amine hardeners
Composite reinforcement based on amine hardeners is more resistant to alkaline influences, as well as prone to elongation
Allowed for use for pre-voltage
Anhydride hardeners
MOST MANUFACTURERS USE
GOST 31938-2012 requires that the reduction in the tensile strength of composite reinforcement after exposure to an alkaline environment is no more than 25%. For armature with anhydride hardeners, this indicator is more than 50%
Subject to corrosion
Weak corrosion resistance of composite reinforcement can lead to rapid destruction of building structures and accidents
Can not be used for pre-voltage
Get production samples
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 by ordering samples with delivery

A few more advantages of composite over metal
Composite armature is cheaper than metal armature and its high strength makes it possible to replace a steel analogue with a large diameter
Saving material
Savings on transportation
Thanks to the compact form of packaging, it is much easier to transport such armature - you can use the trunk of any car
Expansion coefficient like concrete's
There is no imbalance in the reaction of concrete and composite armature with temperature changes - this helps to protect concrete structures from cracking
Low relative density
Having a low weight, composite armature does not create unnecessary loads on the main elements of the structure - it can be used where it is impossible to use metal
Energy efficiency
Heating costs for a building constructed using composites are lower compared to steel armature
Waste-free utilization
The flexibility of the armature makes it possible to reduce the amount of waste down to "No Waste", while waste is certainly present when using metal
