Supported by cement columns, galvanized pipes are used as north-south main beams, galvanized steel wires are laid from east to west, and plastic steel pipes are laid on steel wires in the north-south direction. This warm winter vegetable greenhouse can last at least ten years.

Hello:

If the inner diameter spans from north to south 1 1 meter and the east-west length is not less than 70 meters, the cost per meter is 800- 1000 yuan (east-west length). This fee includes all materials and labor, including automatic rolling shutters and supporting workshops.

You should use grass mulch to keep warm. The investment in the first year will be smaller, but the total use cost will be higher than that of the insulation quilt. The lawn film is replaced once every two to three years, and the service life of the insulation quilt is ten years.

There are photos in my photo album. This greenhouse has the advantages of low basic cost, strong practicability and good wintering ability.

I hope my answer is helpful to you.
