Glass Fiber Reinforced Polymer (GFRP) Rebar
One of the only importers of Glass fiber reinforced polymer (GFRP) reinforcing bars in Australia.
Fiberglass reinforcement is one of the most demanded and modern building materials, widely known in many parts of the world. This popularity is due to the fact that fiberglass has a number of advantages over metal fittings. As many people know from their own experience, metal fittings are very heavy, which requires more effort and time during their installation. In addition, it is susceptible to corrosion, which can ultimately lead to premature destruction of the concrete structure. In turn, fiberglass reinforcement is a lighter and more resistant material to chemical attack, therefore it is more profitable to use it in construction, as evidenced by reviews of fiberglass reinforcement.
Properties of fiberglass reinforcement
Fiberglass rebar is a product created from fiberglass bonded with thermosetting resins. Its main feature is lightness, the indicator of mass per unit volume is only 2g / mm³. It is much easier and more cost effective to work with this material than with metal fittings. Much less cost is required during transportation and directly during reinforcement.
In addition, due to the resistance of fiberglass to corrosion, such reinforcement protects concrete from premature destruction, thus extending the service life of the structure. Fiberglass reinforcement reacts to temperature changes similarly to concrete, which also has a beneficial effect on the strength of the reinforced structure.
The strength of fiberglass in comparison with metal is about 3 times higher. At the same time, the thermal conductivity index is 100 times lower than the thermal conductivity index of steel reinforcement. Therefore, a structure reinforced with fiberglass does not freeze (“cold bridges” do not form) and a building constructed using this material will be warmer than a building based on metal reinforcement. This property of fiberglass allows you to reduce heating costs, so this material is actively used in the construction of modern energy-efficient structures.
All construction and repair organizations will be interested to know that fiberglass is an unusually durable material, which makes it possible to do without additional repair work for 80 years after installation. This is good for composite reinforcement for the foundation.
Fiberglass fittings have found their application in many areas of industry, construction, utilities:
- in construction, it is used in the construction of civil and industrial construction as a basis for foundations, floors, crossbeams, as well as in the construction of earthquake-resistant belts;
- in the construction and repair of roads, reinforcement is used in the arrangement of embankments, road beds, in the construction of bridges and highway barriers. It is resistant to the effects of reagents that are applied to road surfaces (for example, anti-icing reagents), therefore it can be used both in hot and colder regions.
Fiberglass reinforcement will be the ideal base for concrete and brick structures. It is used in the creation of supports for power lines and lighting, in the construction of road, sidewalk and fence plates, as well as in the construction of sleepers on railway tracks. Reinforcement for floors, where reinforcement mesh is used, is widely used, even together with metal.
Fiberglass is applicable in building structures such as monolithic foundations and foam concrete. It is also actively used in the creation of structures that must have increased resistance to the effects of chemicals, for example:
- during the construction of storage facilities for chemical waste and components;
- when arranging sewerage, water supply systems, land reclamation systems;
- in the construction of port facilities and in the strengthening of coastlines.
Despite the uniqueness of the product, fiberglass reinforcement, it is an affordable material for both construction organizations and individuals. Its cost is 40-50% lower than the cost of steel reinforcement, which can significantly reduce costs and at the same time improve the quality of the facilities being built. In general, composite rebar can be called one of the most reliable and efficient building materials of our time.
This reinforcement is made of straight strands of glass or basalt fibers (respectively ASP and ABP), which are collected in a bundle, impregnated with a thermosetting polymer binder, molded, heated (polymerized) and cooled. As a result, a monolithic rod of high strength is obtained, according to the test results, it is 3 times higher than the tensile strength of steel, and the weight, in an equal strength ratio, is 9 times less.
As standard, it is manufactured in the form of rods of any length, at the request of the customer. With a diameter of up to 8 mm inclusive, it can be made in the form of coils (coils) containing 100 meters of reinforcement. Overall dimensions of the bay: height – up to 8 cm, diameter – up to 1 meter.
With a diameter of 10 mm and 12 mm, it can be made in the form of coils (coil fittings) with a length of 50 meters. Overall dimensions of the bay: height – up to 5 cm, diameter – up to 1.5 meters.
