Oval Tube Greenhouse
Share To：
Oval tubes have become popular greenhouse frame materials in recent years due to excellent compression resistance. Early oval tubes were processed from round tubes, which limited their application due to fixed round tube specifications. Nowadays, they are directly made of galvanized strip steel with adjustable length to reduce promotion restrictions. Greenhouses with oval steel frames have a span of 10-20 meters, length of 50-120 meters, ridge height of 5.0-6 meters and side height of about 1.5-1.7 meters. The greenhouse is covered with 0.15mm anti-dripping film fixed by film pressing lines. Electric film rollers are installed at roof and bottom vents for ventilation and cooling in summer. The whole greenhouse is covered with rainproof thermal insulation quilts outside, and electric rolling machines are equipped on both sides.
