marble slab

Marble slabs have structure, black luster, uniformity, and good stability. At the same time, marble slabs have high strength and can still be maintained under heavy loads. Even if they are bumped by heavy objects, at most a few stone fragments will fall off. In addition to the above characteristics, marble slabs also have the "three protections" - anti magnetization and anti deformation.

Marble slab, also known as granite slab, granite slab, rock slab, marble platform, granite platform, granite platform, rock platform, granite slab, granite platform, granite T-shaped groove platform, granite T-shaped groove flat plate, etc.

The precision reference standard for granite slabs, flatness tolerance according to GB4987-85 standard:

Level 000=1 × (1+d/1000) um

Level 00=2 × (1+d/1000) um

marble slab

Marble slabs (4 sheets)

Level 0=4 × (1+d/1000) um

Level 1=8 × (1+d/1000) um

(d is diagonal mm) (Temperature measurement is generally at 20 ± 2 ℃)

Marble slab specific gravity: 2970-3070kg/㎡, compressive strength: 245-254N/㎡, coefficient of linear expansion: 4.61 × 10-6/℃, water absorption rate:; lt;0.13%， Shore hardness: above Hs70.

Marble platform is a benchmark measuring tool made of stone material, which is an ideal reference surface for the inspection of instruments, tools, and mechanical parts. Especially in terms of measurement, due to its characteristics, cast iron plates pale in comparison.
