PO-2 plates are a heavy reinforced concrete fence of rectangular shape with ribbed ledges, that was designed in the 1970s by the lead architect of the “Mosgorstroinadzor”, Boris Lachman.

This particular shape was chosen for its dust and rainwater self-cleaning properties. Since there is no need to do groundwork for the assembly of the barrier, the structure can be mounted in almost any terrain.

PO stands for plate of fencing, “плита ограждения” in Russian, and the figure “2” is the size.

Mesh netting “Rabitz’a” — structural material. Named after the German inventor Carl Rabitz, who was believed to have invented it in 1878. A grid of this type is manufactured with a simple machine by twisting one wire into another. The raw material for the manufacturing of the mesh netting is low-carbon steel wire. Together with the steel wire, a polymer-coated galvanized wire is used.

This kind of netting is often used to create private fences in Russia.
