Wei Chi skeleton equipment shed stent has the following advantages: A, the skeleton selection of high-strength composite materials, make this skeleton has high strength, toughness Haonai significant advantages tide, corrosion, long service life, the life of up to 15 years . B, the curvature of the skeleton using "Greenhouse translucent optimal design" principle of "mathematical model" design and "mechanical principle" production, can absorb maximum sunlight in the winter, the soil long incubation period, skeleton span 6--10 m , back height 2.3--3 meters, the sun through the effective rate of 74% - 85% (latitude difference).
