Introduction to Marble Platform: Marble slabs and platforms are sourced from high-quality underground rock layers. After billions of years of natural aging, their shape is extremely stable, and there is no need to worry about deformation due to conventional temperature differences. The granite materials, after rigorous physical testing and selection, have fine crystals, hard texture, compressive strength of 2290-3750 kg/cm², and hardness of Mohs 6-7. They are extremely wear-resistant, acid-resistant, alkali-resistant, and highly corrosion-resistant, and will never rust. Because marble is a non-metallic material, it has no magnetic reaction and no plastic deformation. Its hardness is 2-3 times higher than that of cast iron (equivalent to HRC>51), so the precision retention is good. In use, even if the rock tool is hit by a heavy object, at most a few stone chips will fall off, and it will not damage the precision due to deformation like metal tools. It is superior to precision measurement benchmark parts made of high-quality cast iron and steel, and can achieve high and stable precision.

Marble slabs and platforms are made of high-quality natural marble materials through mechanical processing and hand polishing. They have a black luster, precise structure, uniform texture, and good stability. They have high strength and hardness, and are rust-proof, acid and alkali resistant, non-magnetic, non-deformable, and wear-resistant, and can maintain stability under heavy loads and normal temperatures.

Marble slabs (marble platforms) are precision benchmark measuring tools made of natural stone materials. They are ideal reference surfaces for the inspection of instruments, precision tools, and mechanical parts. Especially in high-precision measurement, due to its unique characteristics, it makes cast iron plates pale in comparison. Marble slabs and platforms are suitable for industrial production and laboratory measurement work. The main mineral components are pyroxene, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite. They have a black luster, precise structure, and after billions of years of aging, they are uniform, stable, strong, hard, and can maintain high precision under heavy loads.

The marble slabs and platforms produced by our factory are made of high-quality "Jinan Green" natural granite materials through mechanical processing and hand polishing. They have a black luster, precise structure, uniform texture, good stability, high strength, and high hardness. They can maintain stability under heavy loads and normal temperatures.

For example, the '00' grade marble slab and platform of 1000×630mm produced by our factory can still maintain its original precision after being placed for one year.

Characteristics and Advantages of Marble Slabs (Marble Platforms):

• The rock has undergone long-term natural aging, uniform organizational structure, extremely small linear expansion coefficient, and completely disappeared internal stress, resulting in no deformation and high precision.
• Good rigidity, high hardness, and strong wear resistance.
• Unafraid of acid and alkali corrosion, will not rust, does not need oiling, is not easy to stick to fine dust, and is easy to maintain and clean, with a long service life.
• Scratches will not appear, it is not hindered by constant temperature conditions, and it can maintain the temperature measurement accuracy at room temperature.
• Non-magnetic, smooth movement during measurement, no sluggish feeling, unaffected by humidity, and good plane stability.
