Although there are many varieties of products in the stone market and the number of companies, basically every company's quotation method is similar, basically the material fee plus processing fee.
First, the price calculation of the large board (unit: yuan / m2):
Large plate unit price = block price ÷ [1÷ (large plate thickness + saw blade steel sand loss thickness about 5mm)] + processing cost of cutting blocks is about 30 yuan / m2
Remarks: From this formula, we can know that the 20mm thick board of a large company is generally more expensive than the 16mm thick board of Yunfu Small Company.
Second, the finished product specification board price calculation (unit: yuan / m2):
Specification board unit price = large board price, output rate + cutting processing fee
Remarks: The yield rate refers to how many specifications of each large board can be opened, usually 80%. If the finished product size is small, it can be adjusted to 85%. If it is more than 90%, the processing cost of buying large plates will be much lower. The size of the large board is usually L=1900mm H=1600mm. The processing cost of the board is usually 25 yuan/m2 for the large factory and 15 yuan/m2 for the small factory (and usually the finished product price of the small factory is the edging fee, which is also the small factory ratio. The reason why the big factory is cheap.)
Third, the stone line price calculation (unit: yuan / m):
Stone line unit price = material fee + processing fee
Material fee = maximum cross-sectional area ÷ yield rate × block price
Processing fee = stone line width × processing fee per square meter (approximately 800 yuan/m2 of marble and about 1100 yuan/m2 of masonry) Remarks: The bending line needs to increase the difficulty factor of the bending position.
Fourth, the price calculation of cylindrical and special-shaped columns (unit: yuan / article):
The quotation of the cylinder is quoted according to the thickness of the arc plate of the cylinder and the number of spells and radius of the circle. The product of the special column is the surface area of ​​the maximum circumference length and the length of the busbar, multiplied by the processing fee, and finally the material fee is added.
V. Price calculation of engraving products (unit: yuan/set):
The price of the engraving product is calculated according to the material fee plus the processing fee, and the embossing processing fee is about 3,000 yuan/m2.
Sixth, the price calculation of the stigma column product (unit: yuan / set):
Quotation of the column head: The material cost is calculated by dividing the volume by the output rate and multiplying by the unit price of the block. The processing fee is 1000 yuan/m2, and the stone is 1300 yuan/m2 multiplied by the surface area.
