Industries & Applications
Industries & Applications
- Firefighting facilities: Galvanized steel pipes are corrosion-resistant and rust-resistant, and are widely used in firefighting water pipes. They are often painted red as a logo.
- Steel structure welding projects: Galvanized pipes replace welded steel pipes, which is time-saving and durable, especially suitable for steel structure projects.
- Scaffolding: Galvanized pipes replace traditional welded steel pipes due to their good anti-rust performance and are widely used in building scaffolding.
- Manufacturing: Used in machinery manufacturing, transportation, automobiles, agricultural machinery and other industries to provide corrosion protection and strength support.
- High-tech fields: Used in aerospace, nuclear energy and other fields, and are valued for their corrosion resistance and aesthetics.
Other Infomation
Other Infomation
+Z275 means the zinc layer weight is 275 grams per square meter. In addition to +Z (for hot-dip galvanizing), DX51D can also be represented by other symbols according to different surface treatments and coating methods:
- +ZF: Electroplated zinc/zinc-iron alloy coating, good wear resistance, commonly used in home appliances and automobiles.
- +AZ: Alu-zinc coating, strong corrosion resistance, suitable for building exterior walls and high temperature environments.
- +AS: Alu-silicon coating, high temperature resistance, used in equipment such as automobile exhaust and ovens.
- +AL: Aluminum coating, anti-oxidation, used for high temperature equipment.
- +P: Color coating/organic coating, anti-corrosion and beautiful, suitable for roof and wall panels.
Why choose our DX51D Gi Tube and pipe?
- High cost performance and low maintenance cost: Choosing our DX51D galvanized pipe, your initial cost is low, and the maintenance cost is extremely low during long-term use, which is very cost-effective.
- Excellent corrosion resistance and long life: The galvanized layer is uniform, has strong adhesion, and has excellent anti-corrosion performance. Even during cold drawing or bending, the coating will not be damaged, ensuring the beautiful appearance and long service life of the pipe.
- Ordinary galvanized pipes on the market are prone to corrosion and have a short life. We have improved the galvanizing process and surface pretreatment to ensure uniform coating and strong adhesion, and improve durability.
