Is The Stone As Thin As Possible?

Is the stone as thin as possible? No, the thickness of the sheet directly affects the service life!

According to the product type, the natural decorative stone plates in the national standard are divided into conventional plates, thin plates, ultra-thin plates and thick plates.

Conventional board: 20mm thick

Thin plate: 10mm -15mm thick

Ultra-thin board: <8mm thick (for weight reduction requirements of buildings, or to save materials)

Thick plates: plates thicker than 20mm (used on stressed ground or external walls)

The mainstream conventional board thickness in the foreign stone market is 20mm. In order to pursue low prices in the domestic stone market, the thickness of the currently used board in the market is lower than the national standard.

Impact on cost

The cut thickness of block material will affect the output rate. The thinner the plate, the higher the output rate and the lower the price.

For example, the marble output rate, assuming the 2.5MM saw blade thickness

Square slabs per cubic meter of marble block:

18 thickness can produce 45.5 square meters

20 thickness can produce 41.7 square meters of sheet

25 thickness can produce 34.5 square meters of plate

30 thickness can produce 29.4 square meters of sheet

Impact on stone quality

The thinner the sheet, the weaker the compression resistance:

The sheet is thin and has poor compression resistance and is easily damaged; the sheet is thick and strong in compression resistance, and the sheet is not easily damaged.

There may be lesions

If the board is too thin, it may cause the color of cement and other adhesives to reverse osmosis and affect the appearance;

Sheets that are too thin are more susceptible to lesions than thick plates: they are easily deformed, warped, and hollow.
