The greenhouse slot uses hot-dip galvanized steel plate as raw materials, produced by professional equipment, with good anti-corrosion performance, scientific forming, high wind resistance, smooth surface without damaging shed film, thickness is 0.5mm-0.8mm, width is 30mm, height is 12mm, can be double springs, increase wind resistance strength, length is 4m-6m, can also be produced according to customer’s requirements. The supporting spring used is made of high-strength 2.0mm steel wire. The snap-in length is more than two meters. It has strong elasticity, powder coated, good corrosion resistance, anti-aging, and surface is smooth. The greenhouse constructed by the skeleton of the greenhouse is resistant to high temperature, acid and alkali, corrosion, aging, and high comprehensive performance, and is the choice of building agricultural and animal husbandry greenhouse. Convenient installation of steel pipe greenhouse framework, flexible construction method, production, radian, thickness, etc. can be adjusted arbitrarily.
