One: Wall Protection

The three walls of the vegetable greenhouse form its structural framework, simultaneously serving as the key to the stability and insulation of the structure. For newly constructed greenhouses, although chain track vehicles were used to compact the walls and excavators were employed to cut through the walls inside, the inner and outer sides of the three walls, due to loose soil and steep slopes, are often washed away by heavy rains. In severe cases, parts of the walls may even collapse.

Two: Rust Prevention

Now, most newly constructed greenhouses use galvanized steel pipes as the "skeletal" material for the structure. However, the steel pipes available on the market are typically 6 meters long, while the span of the greenhouse exceeds 10 meters. Consequently, greenhouse builders weld two pipes of the same size (usually 1.5-inch pipes) together to make use of them. Little do they know that the welding process can damage the galvanized coating on the pipes.

Three: Drain floodwater

During the construction of new greenhouse structures, the soil in front of the sheds is often removed, yet it remains higher than the ground inside the shed. If the rainy season arrives, there is a high risk of rainwater flooding into the greenhouse. Excessive rainfall and accumulated water inside can lead to several issues: first, the columns inside the shed may sink; second, the foundation of the three walls may be soaked, posing significant risks to both. Therefore, I recommend that all greenhouse owners take proper flood prevention measures during the rainy season.
