The frame in the form of coils is very popular for a number of the following reasons:

The length of 100 meters allows you to cut the bunch according to your necessity. Accordingly, this reduces the amount of wastes, as well as unnecessary costs for them, thus releasing you from the necessity to align individual bars along their original length.

Reinforcing bar coils are transported by any type of transport, even passenger cars, which makes it possible to significantly save on carrier services.

When making large orders, it is possible to manufacture a rod of the coil of any length according to the required dimensions for reinforcement installation.

One of the very significant qualitative characteristics of the non-metallic frame is its self-straightening after uncoiling, as well as the absolute absence of rod deformation. The level of accuracy when uncoiling increases with increasing diameter.

The standard length of coil is 100 meters. The bars are supplied in coils from 50 to 200 meters. The bars have standard length of 6 meters. According to your wishes, as well as the conditions of your order, it is possible to supply the bars of any length.

The national standard of Ukraine for the manufacture, as well as the use of multicomponent reinforcement does not exist. But manufacturers, as well as consumers, use the rules of DSTU-N B B.2.6-185: 2012 “Instructions for the design and manufacture of concrete products and structures with non-metallic reinforcing bars based on basalt and glass roving”, approved by the Ministry of Regional Development, Building and Housing and Utility Services of Ukraine on September 28, 2012. They fully comply with the quality characteristics, as well as the design standards of a multicomponent fibreglass structure. In addition, our experts take into account the provisions of regulatory documents of the leading countries of the world when using fibreglass bars: Russia, Canada, USA, Japan.

When binding the reinforcing bars, the plastic clamps or binding wire are used. There are no technological differences. But we recommend considering the tensile strength of the binding material. The binding wire has the highest coefficient of strength compared with the strength of the plastic clamps. But the low strength of the clamp is easily compensated by the thickness of the tie.

The process of binding the coils is as simple as possible. As for the convenience, as well as the speed of binding with a specific material, it depends more on practice, as well as personal and preferential wishes.

The company does not have any special documents permitting the production of fibreglass reinforcing bars since this kind of reinforcement is not a personal invention of the enterprise.

The beginning of the history of this material dates back to 1870. The mineral wool produced using a powerful steam jet was used for insulation. The first strong, fireproof fibreglass fabric was patented by Herman Hammesfach (1880). Then a patent was issued for the Fiberglas product (1936). The year 1936 was remembered by a patent issued for Carlton Ellis for the polyester resin production technology. British construction had actively been using the material made of glass and plastic. The year 1942 glorified the USA owing to manufacture of resin-impregnated plastic parts, and the year 1964 was remembered by the certificate for the first fibreglass sail-plane. The manufacture of roofing material, swimming pools, electrical insulators, wall panels, plumbing pipes, furniture, containers, insulation materials and other structures using glass and plastic developed and also became more active every year in all countries of the world. Appearance of a large number of companies specializing in fibreglass frames in the United States and Canada dates back to 1970-1980. Thereafter, the manufacture and use of this kind of frame had become widespread in Russia, Ukraine and Belarus.

Based on the foregoing, the company manufactures and sells products known, manufactured and used around the world. And therefore, obtaining special documents for the manufacture of a non-metallic frame is not only irrational, but also impossible.

Concrete, as the main component of any structure, in essence, is already an aggressive environment. Its qualitative characteristics are absolutely accurately described in the papers of Yu. P. Volkov, A.N. Lugovoi and V.F. Savin, titled “Resistance of Fibreglass Reinforced Plastic Bars to the Effects of the Aggressive Environment of Concrete” on the pages of the magazine “All Concrete” published on November 16, 2008.

In addition, it should be noted that the steel frame under the influence of corrosion increases in its diameter by 13 times, thereby weakening and even breaking concrete on its own. Thus and from that moment it is no longer reinforcement.

This forces the consumer to replace the bar or even the entire reinforced structure thus leading to an increase in costs. That is why the corrosion resistance is the main indicator of the durability of the multicomponent structure. Significantly ahead of its steel analogue, the non-metallic frame comes to the fore.

The main thing for establishing pricing policy per tonne of frame is to understand not its weight, but the volume measured in meter coefficient. The bars made of glass and plastic are lighter than steel, and therefore a ton of steel frame is 10 times larger than the fibreglass frame. The price of multicomponent reinforcement per meter is significantly lower by 15-30%. Moreover, the price of a different frame of the same diameter should not be taken as a basis, since multicomponent reinforcement, being thinner, is much stronger (2.5 times) than its steel analogue. And therefore, the concept of “equal replacement” shall not be applied.

In case of incorrect calculation of the volume of reinforcement for a concrete or other structure, the metal reinforcement will stretch and burst at the end. The fibreglass frame does not have tensile properties, while holding the resistance to the utmost.

The indicator of temperature (thermal) distribution in concrete is 0.00001 C – therefore increasing the temperature by 50 C the expansion reaches 0.5 mm/m. Steel reinforcement has a temperature (thermal) expansion indicator of 0.000012 C, and fibreglass reinforcement – 0.00001 C. Therefore, the temperature indicators of fibreglass are very close to concrete.

Reinforcement of foundations using fibreglass frame is the best solution for the developer taking into account physical and technical properties of strength and economic benefits for this kind of basement. That is why replacement technology has gained its popularity in the West, and by the 2000s it also spread to Russia, Belarus, Kazakhstan and Ukraine.

There is no difference between measuring the outer and inner diameter.

It is made in order to increase such characteristics as bonding to concrete material.

A real indicator of the increased bonding to concrete is the changed structure, as well as the shape of the frame bar. And often outer windings do not lead to higher and more stable bonding to concrete.

The weight difference is 4 times higher. And this is subject to full correspondence of the diameter of steel and metal-plastic reinforcement. But in case of equal-strength replacement, the non-metal frame is not 4 but 8 or even 11 times lighter. In addition, this kind of bars is more resistant to aggressive environmental influences, which makes it possible to reduce the use of concrete by one protective layer. Actual weight reduction in certain structures may reach even 25%.

Using a fibreglass frame, reinforced structures may be separated by a heat insulator. In this situation, fibreglass reinforcing bars copes with stopping the process of transferring cold from the outer layer of concrete/brick /to the inner layer. Moreover, the metal has a low thermal conductivity, especially when comparing it with glass or plastic, which increases the level, as well as the freezing rate of the concrete structure. It should also be noted that the metal structure, namely, the end exposed to frost, can lead to crack in the entire structure.

Concrete or brick is only partially shielded, and under the influence of humidity they still reduce the percentage of this process. The steel has always been a good shield.

A perfect material for pouring monolithic floors without undue fear is a multi-component frame.

The diameter of the fibreglass reinforcing bars is established according to the results of the design calculation. In this case, indicators of the load on the foundation are taken into account.

No special tools for the frame made of fibreglass reinforcing bars exist. When binding the base of the structure, a wire or plastic clamp is used. The frame cutting is carried out by a tool selected according to the diameter of its bar: 8 mm – nipping pliers or bolt cutter, over this size – a grinder or hacksaw.

The frame bars have the overlaps, the distance of which is 100 mm of the diameter of the bar used by you. The overlaps are fastened with clamps and joined by filling concrete. Consumers around the world use the reinforcing bars in a vertical or horizontal position of the structure. Statistics show that the number of fibreglass-reinforced horizontal structures as a percentage of vertical is 54%.
