Square hollow section is coated with zinc to prevent oxidation and rust, which ultimately prevents pipe damage. Galvanized steel pipe is a good choice when you need to protect steel pipe from corrosive environments. The protective properties of galvanized pipe are achieved through a hot-dip coating process, where the zinc forms a protective layer that rusts away before any steel is affected. In terms of durability, galvanized steel pipe can last more than 100 years, depends on the degree of corrosion exposure.
Square Hollow Section Specifications
- Grade: Q195/Q215/Q235/Q345/S235JR

Advantages
- Long service life: The uniformity and strong adhesion of the galvanized layer greatly extend the service life of the galvanized pipe. In suburban environments, the service life of a standard hot-dip galvanized anti-rust layer can reach more than 50 years without repair; In urban areas or offshore areas, the service life of the standard hot-dip galvanized anti-rust layer of square hollow section can reach 20 years without repair.
- Economic: The cost of hot-dip galvanizing anti-rust is lower than other paint coatings, and the galvanizing process is faster than other coating construction methods, which can save time and labor.
- Full protection: The full coverage of the galvanized layer ensures that every part of the steel pipe can be protected, even grooves, corners and hidden places.
