A continuous hot-dip process plunges a Middletown Steel Tube into a molten bath of zinc. Each plunge into the 850˚F zinc adds a thin protective layer to the steel’s surface, forming a tight metallurgical bond.
As it cures exposed to the atmosphere, the pure zinc hardens into a formidable barrier against corrosion. More economical than stainless steel, conventional, hot-dip galvanized steel tube is the go-to for many automotive, appliance, HVAC and construction fabrications.
For more specialized applications, look to Phillips Tube’s Galvalume, Galvannealed or Electrogalvanized Steel Tube.
Galvalume Steel Tube
Coated with a zinc-aluminum alloy, galvalume steel tube combines the corrosion and heat resistance of aluminum with the added strength of zinc for an extra sturdy shield against the elements and temperatures. Perfect for applications demanding long-term resistance to atmospheric corrosion, such as automotive fuel and fluid systems, and automotive exteriors and off-road vehicles.
Galvannealed Steel Tube
Galvannealed steel tube receives an all over, continuous coating of zinc before undergoing additional heat. Induction heating alloys the zinc coating with the steel core to create a zinc-iron alloy. The final galvannealed steel tube adds corrosion protection and excellent paint adhesion to the muscle of steel. Common in automotive, HVAC and general manufacturing.

Electrogalvanized Steel Tube
The work of an electric current, electrogalvanized steel tube receives its excellent corrosion resistance from a thinner zinc coating. Without sacrificing protection, Electrogalvanization creates a tube with superior surface quality and smoothness for paintability or powder coating. Popular for auto bodies, appliances and small parts.
