Greenhouse frame

Materials used for greenhouse frames are mostly galvanized pipes.

Galvanized steel pipes, also known as galvanized钢管, are available in two types: hot dipped galvanized and electro galvanized. Hot dipped galvanized pipes have thicker zinc coating, offering advantages such as even coating, strong adhesion, and long service life. Electro galvanized pipes are cost-effective but have a less smooth surface and are much less corrosion-resistant than hot dipped galvanized pipes.
