1、 Don't trust the insurance company to underwrite products: the reason is that you can't meet the insurance conditions. Real insurance companies will have many additional conditions for insurance, such as: at the appropriate temperature, humidity and construction in strict accordance with the standard, as well as the completion date of the room, the degree of dryness and humidity of the ground are strictly controlled, and you also need to provide sufficient evidence to prove that you completed the work under qualified conditions. Think about it, These things may include
greasy cat I
plate thickness: imported plates are basically about 2cm, domestic plates range from 1.4 to 1.8cm, and the thickness varies, so the price is different
therefore, plates of the same quality and color have different JS prices, so when you buy them, you should ask the thickness
greasy cat II:
different processing accuracy
domestic plates have poor processing accuracy. Some of the same batch of plates are 1.5cm thick, and some are 1.6cm thick, The deviation of length and width dimension makes it difficult for the installation of the plasterer, which leads to poor construction quality. The reason is that the equipment can't keep up with it. The worse the equipment is, the lower the price is.
plates have a degree of polishing, some can reach 110 degrees, and some can only reach 70 degrees. Therefore, the polishing equipment is not good, and the same plate has different degrees of polishing, The effect looks different
the store sample is a first-class board, and it is indeed a second-class board for you, which is different from the color difference and processing accuracy
big materials do not make money, small materials make money
big materials (big plates, engineering plates) are basically real price + loss, but the lost materials can be processed into lines, edges, etc, These are the tricks they can earn as much as possible:
confuse the fake with the real
dye it into Sichuan Red with 663, and the price difference is 100 yuan/square.
identify the dyed board by the side of the board. If it is the same as the color of the board (in the case of unpolished), it is dyed. Generally, the undyed edges are white
the dyed board looks dull, Long time will fade
different production methods
marble lines are generally ground from raw materials, with high cost and good quality
but some JS are pasted and then ground into lines with plates, with poor concave convex feeling, but the price is much lower
edging requires good craftsmanship, which is generally done by the teachers of the stone factory
some material manufacturers use small-scale grinding, and the results are high and low.Uneven, The gloss is different, and the cost comes down a lot.
there are water mill and dry mill for edging. The water mill has good quality, the dry mill has poor quality, and the gloss is worse. JS smears oil on the dry mill, hoping to achieve the effect of water mill and obtain higher profits.
different places of origin
take Dahua green as an example, it is made in China, Taiwan, Greece, and the prices are different. The store samples are imported, It is for you to use the domestic
which is also big flower green. The dark ones are more expensive than the light ones. This is also a place for mischief.
some boards have defects, JS uses pencil to repair the color, waxes
some boards have slight cracks, JS uses marble glue and color to repair
so that the secondary board can sell at the price of the primary board
