Hot Dipped Galvanized steel hollow section, also known as galvanized square tubing, is a widely used construction and industrial material. Its popularity stems from its excellent corrosion resistance, high strength, and versatility.
This product comes in a variety of specifications. Smaller sized Hot Dipped Galvanized steel hollow sections, such as those with side lengths around 20 - 50mm, are often utilized in the manufacturing of furniture, like lightweight yet sturdy table and chair frames. They are also favored in the construction of small-scale greenhouses, providing a durable framework that can withstand the elements.
Medium-sized ones, with side lengths ranging from 50 - 150mm, find extensive application in the construction of scaffolding. Their strength and corrosion resistance ensure the safety and longevity of the scaffolding structures during building projects. Additionally, they are used in the production of some mechanical equipment casings, protecting the internal components from environmental damage.
Larger Hot Dipped Galvanized steel hollow sections, with side lengths over 150mm, are commonly employed in large-scale building structures, such as the framework of industrial buildings and some residential high-rises. They can bear significant loads and offer reliable structural support.
In China, there are strict national standards for Hot Dipped Galvanized steel hollow section. The galvanizing layer thickness must meet specific requirements to ensure sufficient corrosion protection. For example, according to the relevant GB standards, the average zinc layer mass per unit area should reach a certain value, which varies depending on the size and application scenarios of the product. The dimensional accuracy also has to comply with the standards, including requirements for side length tolerance, wall thickness tolerance, etc. These standards are crucial to guarantee the quality and performance of Hot Dipped Galvanized steel hollow section in different applications.
