Composite reinforcement – a modern building material that is used in construction for reinforcing foundations, walls, floor slabs, brick and aerated concrete masonry of buildings and structures. OOO NPO Struktura offers composite reinforcement made in accordance with GOST 31938-2012 on the basis of the test report of the A.A. Gvozdev, certificates of conformity GOST R ROSS RU.AG35.N01850, APB.RU.OS2 / 2.H.00788.
* the final cost of the goods and the size of the discount are discussed individually for each client
