Why are the multispan film greenhouses you built so cheap?
A standard multi-storey film greenhouse mainly includes: civil foundation, embedded parts, main steel frame, connecting parts and standard parts, electric external sunshade system, electric internal sunshade system, top and surrounding ventilation Windows, fan and water curtain ventilation and cooling system, top and surrounding covering materials, power distribution system, downspout.
Today's topic is why the multi-span film greenhouse you built is so cheap, a standard multi-span film greenhouse, the price of each construction unit is basically not too bad, if the one-sided cost difference is too much, the quality must be a problem. Write an article today to share, cheap multi-storey film greenhouse is cheap in what aspects?
The first is the design problem, such as the same system configuration, the larger the area, the lower the unilateral cost per square meter. If the area is smaller, the higher the cost per square meter. In addition, when designing, try to span in the length direction and open the space in the width direction, so the design is more reasonable.
The second is the problem of steel frame materials, such as galvanized tape pipes, rather than hot-dip galvanized pipes. Although it is also galvanized pipe, the zinc content of hot-dip galvanized pipe can reach about 200 grams, and the zinc content of galvanized pipe is only about 40 grams
The third is the problem of steel frame specifications, such as whether various steel pipe materials are used too small. There are many kinds of steel used in a multi-storey film greenhouse, such as columns, wind columns, arch rods, sinks, horizontal beams, boom rods, external sunshade columns, external sunshade transverse beams, transmission shafts, push rods, splayed braces, etc., one by one, the price is high and low, is it not small with some materials.
Fourth, the quality of the film, the covering material of the film greenhouse, at least 12 wire film, generally 15 wire is better, too thin film can not be used in the film greenhouse. The same thickness of the film, its life is also different, ordinary po film, life is only about 2 years. Good quality pep film, its life can reach 5 years. The better the quality of the film, the longer its service life, the higher the price.
Fifth, the quality of the sunshade net, this sunshade net refers to the outer sunshade net, the inner sunshade net. If you choose poor quality materials, you can also save a lot of money. Poor quality sunshade net, short life, serious shrinkage, low sunshade rate. That poor quality sunshade net rotted away after more than a year.
Six is the sunshade curtain rod, also known as the sunshade drive side, or the transmission curtain rod, generally aluminum alloy material, some companies in order to save money for the use of steel pipe Goshen greenhouse original replacement, although cheap, but the stability is greatly affected.
Countless, as long as you can think of places, where you can save can be saved, but the future result is that there are various problems in the operation, or quality problems in wind resistance and snow resistance.
