Galvanized steel pipes (GI pipes) are pipes that have been coated with a layer of zinc to prevent rusting and increase its durability and lifespan. This protective barrier also resists corrosion and wear and tear from constant exposure to harsh environmental elements and indoor humidity.
Durable, versatile and low-maintenance, GI pipes are ideal for a number of heavy-duty industrial applications.
GI pipes are commonly used for:
★ Plumbing - Water supply and sewage systems use GI pipes as they can withstand harsh weather conditions and are long-lasting, able to last for 70 years depending on application.
★ Gas and oil transmission - GI pipes are corrosion-resistant or can be applied with anti-corrosion coating, allowing them to last for up to 70 or 80 years despite constant use and extreme environment conditions.
★ Scaffolding and railing - GI pipes can be used to create scaffolding and protective railings in construction sites. Fencing - A GI pipe can be used to create bollards and boundary marks.
★ Agriculture, marine and telecommunications - GI pipes are designed to be resilient against constant use and consistent exposure to changing environments.
★ Automotive and aerospace application - GI pipes are lightweight, rust-resistant and malleable, making them staple materials when constructing aircrafts and land-based vehicles.
