Super Anti-corrosion, No Hurt to Film
We have advanced corrosion prevention technology. The arch made of hot-melting plastic coated steel pipe which has excellent anti-corrosion effects can be used in high concentrations of acid and alkali and high humidity environments. Low endothermic materials keep the temperature of arch surface low under direct sunlight in summer. So it will not hurt film. Clean and bright appearances. If you choose our rainbow greenhouse, no doubt, the life of film will prolong for 1 year.

Steel pipe coated with high-reflective white plastic powder have a strong effect of light reflection, especially in the morning and afternoon(when side light).As usual, the light intensity of rainbow greenhouse is 15% higher than other greenhouse, equal to accumulate additional additional one hour illumination per day.

High Wind Resistance and Compressive Strength
We use rectangle steel pipes for arch materials to make the greenhouse has high compressive strength. And arches have been strictly static pressure tested. Streamline shape design providing a great wind resistance can withstand 29m/s the wind speed.

Utilitarian and Multifunctional
On rainbow greenhouse you can complete ventilation in a few seconds using manual ventilator, as a result, it is easy to control the temperature accurately. So rainbow greenhouse can satisfy your rigorous temperature requirements to plants cultivation and growing. Swallowtail grooves hold film firmly and it is easy to install and uninstall.

Beautiful Appearance and Reasonable Price
