where your gilm greenhouse so cheap?
A standard multi-span film greenhouse mainly consists of: civil engineering foundation, embedded parts, main steel frame, connecting and standard parts, electric external shading system, electric internal shading system, ventilation windows on the top and sides, fan and water curtain ventilation and cooling system, covering materials on the top and sides, power distribution system, and downspouts.
Today, I'm sharing a topic: Why is the multi-span film greenhouse you built so cheap? For a standard multi-span film greenhouse, the prices offered by each construction company polycarbonate greenhouse basically won't vary much. A difference of about 10 yuan per square meter is about right. If the unit price varies too much, it definitely indicates a quality issue. Today, I'll write an article to share in which aspects the cheap multi-span film greenhouses are actually cheap.
One issue is design. For instance, with the same system configuration, the larger the area, the lower the unit cost per square meter. Conversely, the smaller the area, the higher the unit cost per square meter. Additionally, when designing, it is advisable to have polycarbonate greenhouse the span in the length direction and the bays in the width direction, as this is a more reasonable design approach.
The second issue is related to the steel frame materials. For instance, using galvanized strip pipes instead of hot-dip galvanized pipes. Although both are galvanized pipes, the zinc content of hot-dip galvanized pipes can reach around 200 grams, while that of galvanized strip pipes is only about 40 grams.
The third issue is related to the specifications of the steel frames. For instance, was the amount of various steel materials used too small? A single-span plastic greenhouse requires glass greenhouse a wide variety of steel components, including upright columns, wind-resistant columns, arch beams, water tanks, horizontal beams, suspension rods, external shading glass greenhouse upright glass greenhouse glass greenhouse columns, external shading cross and longitudinal beams, transmission shafts, push rods, and eight-strap supports, etc. By comparing each component, we need to determine whether certain materials were used in too small quantities,glass greenhouse.
Fourth, the quality of the film. For the covering material of the multi-span film greenhouse, at least 12-thread film is required. Generally, 15-thread film is better. Too thin films cannot be used in multi-span film greenhouses. For the same thickness glass greenhouse of film, their lifespans also vary. Ordinary PO film has a lifespan of only about 2 years. High-quality PEP film can have a lifespan of up to 5 years. The better the quality of the film, the longer its lifespan and the higher its price.
The fifth point is about the quality of the shading nets. These polycarbonate greenhouse shading nets refer to both the outer shading nets and the inner ones. If you choose inferior materials, you can save a lot of money. Poor-quality shading nets have a short lifespan, severe shrinkage, and a low shading rate. Those poor-quality shading nets will deteriorate and fall polycarbonate greenhouse apart within just one year of use. Sixth is the shading pole, also known as the shading drive edge, or the transmission pole. It is usually made of aluminum alloy. Some companies, in an attempt to save costs, use steel pipes instead. Although it is cheaper, its stability is greatly affected.
The seventh point is about the construction issues. A competent construction team can ensure a solid installation, with straight and vertical lines, and no leakage. All systems operate smoothly. However, an irresponsible installation team polycarbonate greenhouse encounter numerous problems, especially leakage, and the systems will not operate stably, always causing issues.
The eighth issue is about the connection. Standard multi-span plastic polycarbonate greenhouse film greenhouses are all connected by bolts. Except for the welding at the bottom of the columns, all other parts are connected by bolts. This ensures polycarbonate greenhouse good hot-dip galvanizing anti-corrosion performance. Some construction units build multi-span plastic film greenhouses, polycarbonate greenhouse welding here a little, there a little. With various glass greenhouse welding points, the anti-corrosion performance of the steel frame is not guaranteed, and the strength and lifespan are also affected,glass greenhouse.
