For friends who are interested in buying stone, the following information is the content that needs special understanding.

First, how to calculate the quotation of stone?

There are many kinds of decorative stones, and there will be many different types of finished products in the process of use and processing, such as ordinary plates, patchwork, abnormity, mosaic and so on. , and the quotation method is different.

The products usually quoted are finished standard boards, ordinary standard boards, and then finished stone materials such as cylindrical railings and imitation lines.

Finished specification stone material

According to the usual practice of stone curtain wall, the thickness is usually 18mm, 25mm and 30 mm Taking these three cases as examples, the process of calculating material price is explained:

1. Stones should be cut and processed into usable shapes and thicknesses. According to 18mm and 8mm sawing, each cubic meter of block can be exported1000 ÷ (18+8) = 38.46m2..

2. The price of raw materials is usually 6000 yuan /m3. Considering the felling fee of 80 yuan /m2, the cost price is 6000÷38.46= 156 yuan /m2, and after adding the felling fee, it is 156+80=236 yuan /m2.

3. Due to different specifications and sizes, there is a problem of cutting utilization rate of stone plates, which is generally 90%. Considering the influence of cutting loss, the cost price should be 236÷90%=262 yuan/㎡.

4. Stone manufacturers should generally consider the profit ranging from 15% to 30%. If calculated by 15%, the manufacturer's quotation should be 262÷85%=308 yuan.

5, stone freight 18mm stone 8 ~ 10 yuan/㎡, 25mm stone 14 ~ 16 yuan/㎡, 30mm stone 18 ~ 23 yuan/㎡, all consider one-time loading and unloading, and the choice of cost level mainly depends on the project.

For example, the price of 25mm stone is:1000 ÷ (25+8) = 30.30m2; 6000÷30.30= 198 yuan/㎡; 198+80=278 yuan/m2 278 ÷ 90% = 309 yuan/m2; 309÷85%=363 yuan/㎡, after considering the freight, 363+ 14=377 yuan/㎡.

For example, the price of 30mm stone is:1000 ÷ (30+8) = 26.31m2; 6000 ÷ 26. 1 = 228 yuan/㎡; 228+80=308 yuan/m2 308 ÷ 90% = 342 yuan/m2; 342÷85%=402 yuan/㎡, after considering the freight, 402+ 18=420 yuan/㎡.
