What ASTM and EN standards does Guyun comply with?

Guyun (Antique) exceeds ASTM C568 Category III (High-Density Limestone ≥ 2,560 kg/m³), testing at 2,650 kg/m³ bulk density, ≤ 1.8% water absorption (ASTM C97), ≥ 105 MPa compressive strength (ASTM C170), 11.4 MPa flexural strength (ASTM C880), 100-cycle freeze-thaw integrity (ASTM C666), EN 1341/1469 CE compliance, and GOST 30629-2011 F100.

How many square meters of Guyun fit inside a 20GP container?

Based on a 27-metric-ton 20GP payload from Xiamen Port (CNXMN), one container holds ~650 m² of 15mm tiles, ~500 m² of 20mm pavers, ~320 m² of 30mm exterior pavers/coping, or ~190 m² of 50mm vehicular cobblestones.

Can Guyun be ordered in French Pattern and custom CNC pool coping?

Yes. We fabricate Guyun in 600×400mm, 600×600mm, 900×600mm, 4-size Modular French Pattern (0.743 m²/set), Full Bullnose and 30/75mm Rebated Drop-Face pool coping, stair treads, and 5-axis CNC profiles.
