The Impact of Stone Slab Thickness on Usage
1. Standard Thickness of Stone Slab
According to the national standard, natural decorative stone slabs are classified into regular slabs, thin slabs, ultra-thin slabs, and thick slabs based on product type.
Regular Slab: 20mm thick
Thin Slab: 10mm - 15mm thick
Ultra-Thin Slab: Less than 8mm thick (used when there is a weight reduction requirement for buildings, or to save materials)
Thick Slab: Slab thicker than 20mm (used for load-bearing floors or exterior walls)
The mainstream thickness of regular slabs in the international stone market is 20mm, while the domestic stone market, in pursuit of low prices, has resulted in the thickness of slabs commonly used in the market being lower than the national standard.
2. The Impact of Stone Slab Thickness
1. Impact on Cost
Different thicknesses of slabs affect the yield rate of the stone. The thinner the slab, the higher the yield rate, and the lower the price.
For example, the yield rate of marble slabs, assuming a saw blade thickness of 2.5mm:
18mm thick can produce 45.5 square meters of slabs
20mm thick can produce 41.7 square meters of slabs
25mm thick can produce 34.5 square meters of slabs
30mm thick can produce 29.4 square meters of slabs
2. Impact on Stone Quality
The thinner the slab, the weaker the compressive strength:
Thin slabs have poor compressive strength and are prone to damage;
Thick slabs have strong compressive strength and are not prone to damage.
3. Potential Diseases
Slabs that are too thin may cause the color of cement and other adhesives to seep up, affecting aesthetics;
Slabs that are too thin are more likely to develop diseases compared to thicker slabs: prone to deformation, warping, and hollowing.
4. Impact on Service Life
Stone has its particularity, and after a period of use, it can be polished and renovated to regain its luster.
During the polishing and renovation process, the stone will wear to some extent, and slabs that are too thin may eventually produce quality risks.
