Composites - a new player in the rebar market

The first use of composite rebar was back in the 60s of the twentieth century. It is much lighter and more durable than steel rods, but also much more expensive, nevertheless, it is increasingly finding its place.

The list of advantages of composite rebar is quite long. Let's start with the fact that it is 5-6 times lighter than steel, which facilitates transportation and installation on the construction site, since the use of heavy equipment is not required. Composite rods are also 2.5 times stronger than steel. Thus, smaller diameter rods can be used, which can also be used for a thinner concrete layer.

However, at present, the most widespread use is provided by another feature of composites - resistance to corrosion caused by the harmful effects of water, especially salty, alkaline or acidic media. So, the bridge built with the use of steel reinforcement needs to be repaired in 6 years. In the case of using composite rods even after 18 years, this is not necessary.

Corrosion resistance favors the use of these rods in water features or wetland conditions. Composite rods are not afraid of not only rust, but also many aggressive chemical or organic substances. So, they are readily used, for example, in objects related to agriculture and animal husbandry, where floors and walls are very aggressive. It is also advisable to use composites when creating floors for industrial facilities, where there are high requirements for strength due to acids, fats or other corrosive liquids.
