Domestic, generally 0.5mm- 12mm thick. Imported can be foamed at one time, but the price is more expensive.

Coil quotation, 0.5 mm/600 m,1mm/300 m, 2 mm/150 m, 3 mm/100 m market price is110 yuan, see its regeneration.

Composite coils and large plates are generally 0.37-0.39 per square meter (length 1m* width 1m* thickness 1mm), which is cash excluding tax.

Profile, according to reality, is generally calculated as the longest and widest volume of direct beer, and the actual materials are used for bonding, plus hot melt adhesive. Generally, it is 0.55 yuan per square (length 1m* width 1m* thickness 1mm). The bonding is about 0.1mm.
