Galvanized steel tube is continuously coated on both sides of the sheet with a zinc coating. This provides a tight metallurgical bond between the steel and coating. The zinc coating protects the base steel by becoming a barrier to corrosive elements, which makes galvanized steel popular in the automotive, appliance, HVAC and construction industries.
On top of conventional galvanized steel (sometimes referred to as hot dip galvanized), Shelby Welded Tube builds a variety of specialized tubing products that each provide unique benefits for your application: galvalume, galvalume and electrogalvanized.
Galvalume Steel Tube
Galvalume steel tube combines the barrier corrosion protection of aluminum with the galvanic protection of zinc. This coating is perfect for applications that need long-term resistance to atmospheric corrosion, such as automotive fuel and fluid systems, and automotive exterior and off-road vehicles.
Galvannealed Steel Tube
Galvannealed steel tube is continuously coated on both sides with a zinc-iron alloy. A variation of galvanized steels, galvannealed steel tube uses induction heating to alloy the zinc coating with the steel in order to create a zinc-iron coating. This gives the tubing the strength of steel while having the additional protection of the coating. It’s common in automotive, HVAC and general manufacturing.
Electrogalvanized Steel Tube
Electrogalvanized steel tube is useful in applications that demand superior surface quality, corrosion resistance and paintability. This coating delivers both galvanic and barrier protection against corrosion. Electrogalvanized steel tube is popular for auto body and appliances.
