Overview

About Grey Basalt

Grey Basalt is a medium-to-dark grey volcanic stone quarried in Shandong and Hebei provinces. Its neutral grey tone makes it highly versatile — complementing both traditional and contemporary architectural styles. The stone has excellent compressive strength and frost resistance, making it a popular choice for municipal infrastructure projects including roads, pavements, and kerbstones, as well as commercial landscaping and building facades. Shandong Kingstone supplies Grey Basalt in tiles, slabs, kerbstones, cobblestones, and custom-cut formats. Factory direct export with full quality documentation.

Appearance: Medium to dark grey, uniform colour with fine grain. Minimal pattern variation. Clean, contemporary appearance.
