Calculation method of curtain order length: BOMAN recommends that you calculate the curtain length you need according to the following formula: curtain order length = greenhouse theoretical length (note ①) + greenhouse theoretical length × curtain physical shrinkage rate 0.5% (or 1%, note ②)+Theoretical length of the greenhouse × 1% of the sag of the curtain under its own weight (Note ③) + the designed drape length of each section of the curtain (Note ④) × 2 Example: If the theoretical length of a greenhouse is 50cm, calculate according to the above formula, order the curtain The length should be:
50 + 50 ×0.5% + 50 ×1%+0.6 × 2 =51.95m Note ①The length of the greenhouse refers to the theoretical length when the greenhouse is designed. Note ②The physical shrinkage rate of the curtain. Boman’s screen is 0.5%. If the length of the greenhouse is 50cm, the physical shrinkage of the greenhouse is 50×0.5%. PES10 insulation screen generally considers 1%. Note ③ The amount of sag of the curtain after installation (depending on the installation quality, generally consider 1%) Note ④ The sag at both ends of the curtain is mainly for the sealing of the curtain system (cooperating with the closed curtain) and keeping the curtains at both ends neat Sex (combined with counterweight), etc.
For the design of the drape length at both ends of the curtain, please refer to the following table for suggestions:
The theoretical length of the greenhouse suggests the drape length of each section of the curtain
BOMAN reminds you:
Receiving and storage:
1. When you receive the goods, if you find that the goods are damaged, you should notify us immediately. At the same time, you must indicate the damage on the freight bill and be signed and approved by the carrier, otherwise you can choose to reject or push the goods.
2. In order to avoid mechanical damage to the screen, please do not use ordinary forklifts to unload; the floor where the goods are stacked should be cleaned, and the goods should be avoided from being pulled on the ground to avoid being scratched by some sharp objects.
3. If you need to store the goods for a period of time, please place them in a cool and dry place.
