Description

Centrifuged reinforced concrete cylindrical stand STs22.1-1.1, GOST 22687.0-85, GOST 22687.2-85, GOST 22687.3-85 is a building structure used as a support for power lines and other structures. It is made from reinforced concrete by centrifugation - rotating the mold with concrete around its axis, which allows you to evenly distribute the concrete throughout the mold and increase its strength. The density of concrete is 2200-2500 kg/m3.

The shapes are divided into cylindrical and conical racks. Options are available with division into sections (sectioned), which facilitates the transportation and storage of long reinforced concrete products.

The reinforced concrete centrifuged cylindrical rack STs22.1-1.1, GOST 22687.0-85, GOST 22687.2-85, GOST 22687.3-85 is used in various branches of construction, including the construction of power lines with a voltage of 35-750 kV and other engineering structures. With its help, reliable support for heavy structures and the ability to withstand heavy loads are provided.

The main positive qualities of the reinforced concrete centrifuged cylindrical rack STs22.1-1.1, GOST 22687.0-85, GOST 22687.2-85, GOST 22687.3-85 are their significant wear resistance, durability and resistance to atmospheric phenomena and aggressive environments. Thanks to these qualities, it is widely used in the installation and reconstruction of power lines, as well as during repair work.

All products offered by StalEnergo-96 LLC undergo quality testing in accordance with generally accepted standards GOST, OST, TU, AISI, DIN, ASTM.
