The small parts of the greenhouse shading (heat preservation) system should generally follow the following quantitative principles:

1. Curtain line: transparent PET curtain line is used inside, and PET black anti-UV curtain line is used outside.

1) The outer shading curtain line is within the width of each zone, and the spacing is generally 500mm, and the upper and lower curtain lines use the same spacing.

2) The inner shading (using curtain) is within the width of each zone, the distance between the lower curtain line is 500mm, and the distance between the upper curtain line is 2000mm.

3) Inner insulation (V-shaped, using non-drip film), within the width of each zone, the screen line spacing is about 150mm, in order to make the water droplets smoothly slide into the bottom of the V-shaped groove, there is no upper screen line.

4) If there are both upper and lower curtain lines, the distance between the upper and lower curtain lines is not less than 50mm.

5) When there is a heat preservation pocket, the edges of the heat preservation pocket 2 are straightened by curtain wire, and the cable tie is fixed on the curtain wire.

6) PET curtain wire has good tensile performance and elongation at break. The 2025 type curtain wire can withstand a tensile force of not more than 150kg, but the abrasion resistance is slightly worse. The design should avoid friction between the curtain wire and the sandy object. Consider the influence of wind load.

7) When the outer shading curtain line is fixed, the intersection of the bottom curtain line and the crossbar must be wound once, and this length should be added in the design.

Have to look at the wrong installation details

I say, dear customers, the shed built with money is destroyed by a few wires and a few parts. ! !

When you vowed to accuse the manufacturer of quality problems, you have reflected on it

1. Are there any loopholes in the installation?

2. When the wind is strong, is the sunshade closed?

3. Is there someone in your greenhouse?

......

Can you increase snacks?

Customers, don’t let the money go

Let's take a look at the correct installation:

Inner screen cable installation:

External screen cable installation:

2. Stainless steel wire + anti-friction tube:

1) The side of the outer sunshade screen has two sagging ends on each side, and four in each zone, with a vertical distance of about 350mm-500mm.

2) The side of the inner sunshade screen has a drooping end, one on each side, two per partition, and the upper and lower spacing is about 350mm-500mm.

3) External sunshade (V-shaped internal heat preservation) is used for reinforcement at both ends to increase wind resistance (for external use) and improve wear resistance, generally one per 3~4 meters, Venlo greenhouse can be arranged according to one per spire .

Look at how foreigners solve the side curtain anti-friction:

3. Aluminum binding wire:

1) The intersection of the inner shading (heat preservation) curtain wire and the beam needs to be bound by aluminum binding wire to avoid slippage of the curtain wire.

2) In the inner sunshade, when the card slot is not used to fix the curtain, the aluminum binding wire is single-stranded at a pitch of 0.25m to fasten the fixed end of the curtain; and bind the curtain wires at the same position.

3) In the external sunshade, when the card slot is not used to fix the curtain, the aluminum binding wire is double-stranded at a distance of 0.25m to fasten the fixed end of the curtain and bind the curtain wire at the same position.

We always adhere to the business philosophy of integrity, equality, and customer first, and provide customers with powerful product design solutions. Based on fast, high-quality and pious service, the company has become a dynamic and competitive professional manufacturer of sun-shading and thermal insulation screens.
