Indoor Growing Polycarbonate Tomato Greenhouse Trellis Cover 8mm PC Sheet 100x100m Venlo Roofing
Product Features
The name of the polycarbonate greenhouse comes from the covering material. Since the secondary greenhouse is covered with PC boards, it is named the solar polycarbonate greenhouse. Sun panel tomato greenhouses are mainly used to grow tomatoes and other vegetables. This type of greenhouse is often used in large agricultural farms. The structure of the polycarbonate greenhouse is strong.
The structure of the polycarbonate panel has a longer service life than the film and does not need to be replaced within 10 years. The construction cost of a polycarbonate greenhouse is lower than that of a glass greenhouse. And it is easier to transport than film greenhouses. In all foreign projects, customers choose polycarbonate greenhouses more than film greenhouses and glass greenhouses.

Physical properties of polycarbonate plastic
Polycarbonate (PC) is an amorphous thermoplastic engineering plastic. It has extremely excellent toughness, transparency,
Excellent impact resistance, deformation resistance, excellent dimensional stability, heat resistance, flame retardancy, processability, sound insulation, etc.
Polycarbonate board products used as covering materials for agricultural greenhouses are generally divided into two series: hollow boards (two or three layers) and corrugated boards (also called corrugated boards). In order to meet the lighting needs, greenhouses usually use colorless and transparent sheets.
Common specifications and characteristics of polycarbonate sheets for greenhouse covering:
Thickness: 6mm/8mm
Transmittance: >78%
(1) Plate cutting and drilling: polycarbonate sheet(PC panel） can be cut and drilled with ordinary tools. If you use an ordinary electric circular saw or a hacksaw with a sharp paper knife to cut, do not remove the protective film when cutting, and blow off the sawdust inside the board after cutting. When drilling holes in a polycarbonate sheet(PC panel）with an ordinary twist drill or beveled wedge drill, small holes should be drilled first, and then gradually expanded to the required diameter. The distance between the drilled hole and the edge of the board should be greater than 50 mm, and the diameter of the drilled hole should be greater than The screw diameter is 30% to 50% to adapt to the thermal expansion and contraction of the board, and there must be support underneath to prevent shaking. Due to the thermal expansion and contraction of the polycarbonate sheet(PC panel）, actual investigation shows that the construction effect in winter is not as good as that in summer.
Distinguish the front and back sides of the polycarbonate shee t(PC panel）board. When installing, first distinguish the front and back sides of the board. There are PE protective films on both sides of the polycarbonate sheet(PC panel） board. Generally, the side with the printed logo is a protective surface against UV rays. This side must face outward during installation. Since the protective film will affect the combination of the supporting material and the polycarbonate sheet(PC panel） board, before embedding the installation, lift off about 5cm around the protection to facilitate construction.
The most important issue during installation is the sealing of the openings at both ends of the polycarbonate sheet PC panel board. If there is moisture, dust, bugs or other substances inside the hollow board, it will affect the light transmittance, thermal insulation and performance of the polycarbonate sheet PC panel board. Aesthetics. The colored edge-sealing tape provided by the manufacturer when leaving the factory is only for temporary protection during transportation and is not used for waterproofing and installation. It should be torn off before installation, and the top edge of the board should be replaced with sealed dust-proof tape and the bottom edge with breathable tape. Dust-proof tape to allow condensation formed inside the board to drain away and prevent dust
The solar polycarbonate sheet PC panels board are directly fixed on the panel support structure through self-drilling and self-tapping screws (Figure 1) or fixed on the support structure through aluminum alloy connection sealing profiles (Figure 2). Due to the high cost of aluminum alloy connecting and sealing profiles, self-drilling and self-tapping screws are often used to directly replace some aluminum alloy profiles during greenhouse installation to reduce costs.
