This crushed stone in the 5–20 mm fraction is produced by SHKOTOVSKY DSK LLC, a crushing and screening complex based in the village of Tsaryovka, Shkotovsky district of Primorsky Krai, in the Russian Far East. The material is made from dense igneous rock — diorite — quarried at the company's own "Ferma" deposit, and its tested physical and mechanical characteristics meet the requirements of GOST 8267-93 for Group 1 crushed stone by grain shape.
This is the so-called cuboid grade, the highest quality class: the content of flaky and needle-shaped grains does not exceed 10%, and the near-cubic grain geometry allows maximum packing density with minimal voids between grains. The stone carries a crushability grade of M1400 and a frost resistance rating of F300, figures that place it among the strongest aggregates available for construction work.
The producer positions itself as one of the largest manufacturers of premium cuboid crushed stone in Primorsky Krai, and its catalogue spans the full range of non-metallic materials — crushed stone fractions from 5 to 120 mm, crushed-stone-sand mixes, crushing-screening sands, gabion and hydraulic engineering stone. Every shipped batch is accompanied by quality documentation, and the 5–20 mm fraction is a stock item held at the plant's warehouse, available for pickup or delivered supply.
