American standard square pipe A500 Grade B, C, and D all adopt the A500 standard issued by the American Standards Association (ASTM), which means that they meet internationally recognized standards in terms of quality and performance. It can be widely used in building structures, machinery manufacturing and other fields.
Galvanized angle steel is a specific type of galvanized steel. Galvanized steel is a steel material that has been galvanized. Galvanizing is a technology that coats the surface of steel with a layer of zinc. This layer of zinc can prevent the steel material from corrosion.
After hot-dip galvanizing, a zinc layer is formed on the surface of the steel. This zinc layer can effectively isolate the steel from the external environment, prevent oxygen, moisture, etc. from corroding the steel, and greatly extend the service life of the angle steel. It is especially suitable for humid and corrosive environments, such as seaside buildings, chemical plants, etc.
Galvanized rectangular pipe tube is a galvanized rectangular steel tube with a rectangular cross section. Common materials include Q195/Q215/Q235/Q345, ST52, ST37, etc. Different materials have different strengths and characteristics. Surface treatments include galvanizing, black, spray painting, etc. The amount of galvanizing generally ranges from 30 to 650g. There are various packaging methods, including steel strapping, PP woven materials and waterproof plastic packaging, etc., and packaging can also be done according to customer requirements.
Hot dipped zinc steel pipe tube is a specially treated steel pipe with a uniform zinc layer on its surface. This treatment method usually involves immersing the steel pipe in molten zinc liquid, allowing the zinc liquid to penetrate the surface of the steel pipe and form a strong bonding layer. This process not only improves the corrosion resistance of the steel pipe, but also enhances its aesthetics and durability. Hot-dip galvanized steel pipe is widely used in various industrial fields, such as construction, oil, gas, chemical industry, etc.
