ASB develops its products based on TS 621 Standard. In our laboratories, we are constantly making improvements with our technical teams to meet the needs of our customers in order to offer the best quality products for the best price. We can produce our products in desired quality and dimensions according to the standards of all the public and private organizations (such as ASKİ, DSİ, İller Bank, Special Provincial Administrations, Village Services, Cooperatives, etc.). In the production of infrastructure elements, chemical additives suitable for TS 706, sulphate resistant cement according to TS 10157 standards and TS 3452 are used. For the diameter of 800-2200 reinforced concrete pipes, the inspection shaft body rings, the inspection chimney floor and the inspection shaft reduction lids, TSE 4559 straw steel is used in accordance. Our prefabricated pipe and inspection chimney elements are made of steam cube. As a result of the tests made on the structural elements, the most suitable concrete mixture recipe is used to achieve high strength and minimum body tightness and the production is kept under constant control.
