Why should the steel framework of a greenhouse be avoided from being welded asap?
When building greenhouses, whether it is single-arch sheds, solar greenhouses, multi-span film greenhouses or glass greenhouses, the hot-dip galvanized steel frames should be avoided from being welded as much as possible. The main reasons are as follows.
Poor anti-corrosion performance: Welding will damage the hot-dip galvanized layer of the steel frame, affecting its anti-corrosion performance, making the steel frame more prone greenhouses hot-dip galvanized for sale to rust and corrosion, and shortening its service life.
2. Installation is complex: During the processing and installation of the welded steel frame, problems such as inconsistent welding standards often arise. The installation process is time-consuming and labor-intensive. Once the installation fails, the on-site workers will directly resort to using welding machines for handling. This results in numerous welding points all over the greenhouses for sale place, and the high-altitude rust prevention treatment for these welding points is very difficult for the workers to carry out.
3. Incorrect material matching: The welded structure is caused by the failure to follow the hot-dip galvanized standard processing drawings during greenhouses for sale material processing, resulting in mismatched shading or driving materials and making installation impossible.
4. Poor safety performance: The welding skills of the workers vary greatly. Some welding points fail to meet the welding standards. Or some welding points do not have additional reinforcement plates, or are limited by local machine restrictions and cannot cut steel plates to the greenhouses for sale standard thickness, thus using thinner steel plates, which will inevitably affect the safety performance of the main frame.
5. Cost increase: Although the material cost of the welded steel frame might be lower, the costs of labor, welding, installation, and subsequent maintenance will increase. As a result, the hot-dip galvanized overall cost has actually risen.
6. Impact on service life: The anti-corrosion performance of the welded steel frame is poor, which will affect the stability of the entire frame and subsequently shorten the overall service life of the covered greenhouse. The standard prefabricated main steel frame has a lifespan of about 10 to 20 years, while the welded covered greenhouse frame can only last for 5 to 8 years greenhouses for sale .
To ensure the quality and durability of the greenhouse, it is recommended to choose a reputable manufacturing company and use the prefabricated bolting method to connect the steel frame. When selecting the steel frame for the greenhouse, factors such as greenhouses for sale wind load and snow load resistance, as well as choosing greenhouses for sale appropriate frame and covering materials hot-dip galvanized based on the local natural environment, should also be considered. At the same time, attention should be paid to the rust and corrosion prevention treatment of the steel frame to extend its service life.
