Sirep — for more than 20 years we have been producing fiberglass composites
SIREP is a Russian manufacturer of modern composite materials for industrial and civil construction, electric power industry and road industry. For more than 20 years, we have been producing such composite construction materials as composite reinforcement, reinforcing mesh, diagonal flexible ties, and mounting loops. SIREP products have quality certificates and meet quality standards
SIREP production: 1,000,000 units per year
SIREP, owned by RPP JSC, is a Russian manufacturer fiberglass composite products for industrial and civil construction and the road industry. The company is based in the city of Cheboksary (Chuvash Republic). The area of ​​production facilities is 4,000 square meters. The company employs more than 50 qualified employees, and the production volume reaches one million units per year.

The company produces a wide range of flexible mounting loops for concrete products with various load capacities, composite diagonal flexible links for sandwich panels, composite reinforcing mesh, as well as composite reinforcing bars with a sandy coating that improves adhesion to concrete.

SIREP composites are uniquely formulated with hot curing amine hardeners, making them much more resistant to the alkaline action of concrete and prone to elongation, allowing them to be used for prestressing.

All SIREP products are protected by patents and are the intellectual property of the company. Thanks to a strict quality control system, SIREP products have the necessary certificates of conformity, as well as the ISO9001 international quality certificate.

The unique high-tech equipment of SIREP's own design allows the production of composite products of the highest degree of reliability, and at a very competitive price. In terms of quality, SIREP products are superior to traditional counterparts in their segment. That is why more and more large developers in Russia trust the reliability of SIREP products and introduce them into their production

Company history
The company "Sirep" is a part of AO RPP (joint-stock company), which was established in 1998
The first launch of the production of flexible ties. The first delivery was organized in the Mechanized Housing Construction Column of Gesstroy
Launch of production of fiberglass reinforcement. AO RPP is one of the few enterprises in Russia that complies with all the standards in the manufacture of fiberglass reinforcement
A patent for a fiberglass mesh was obtained and production was launched. The uniqueness of this mesh is that it is made of fiberglass with an amine hardener, and that all intersections of straight and longitudinal lines in the mesh are protected by a plastic joint
Start of production of prestressed composite reinforcement. It is used in supports, columns, beams. Only reinforcement made with amine hardeners is suitable for prestressing. This is a promising direction, which is widely used in support racks for the contact network

A patent was obtained and the production of drill piles was launched
Launch of production of diagonal flexible ties, which is a type of flat framework that is used as flexible natural ties. It is used in house-building plants. The prototype samples have been tested in PIK Group.

The production of flexible mounting loops has been launched. They greatly simplifiy the manufacturing and application of concrete panels. They are widely used in PIK Group
Production of composite mesh for thin-layer concrete structures has been launched. The advantage of this mesh over similar products is that it does not need to be fixed in concrete layer — integrated spacers are used at the intersection of the longitudinal and transverse rods
The development of the construction sector has led to the fact that during the construction and subsequent operation of objects, it is important to know what changes are taking place in building structures

For these purposes, the company AO RPP in 2020 produced the first prototype of "smart bar". A special feature of the technology is the laying of a fiber-optic cable in a composite reinforcement bar, which later allows to track changes in the construction structure

This technology is especially relevant for construction in earthquake areas, as well as in permafrost zones
