How to calculate the tuyere price of ABS central air conditioner in Shanghai? What is the square of 1?

Calculation formula: size of the hole length and width plus 0.05, multiplied by ㎡. The unit price is equal to the tuyere price, such as: opening size: double-layer louver tuyere, length 850mm, width 300mm (0.85+0.05)*(0.3+0.05)* market price = tuyere price.

Please note that PVC is used as ABS tuyere in the market now. PVC is very heavy, it will deform in winter, and its price is cheap. ABS is light in weight, will not deform, and its price is relatively high. ABS tuyere of the same size is as light as aluminum alloy, and PVC tuyere is very heavy. Take it, the weight is obvious.
