Why Coated Low Carbon?

Using a scientifically enhanced Aluminum/Zinc based coating, Alt-Linetm has superior resistance to enviromental and weather induced corrosion problems. In long term tests against copper tubing in coastal areas with high concentrations of salt in the air, refigeration systems using this coating process have shown remarkably improved resistance to the corrosion familiar to all HVAC Installers and owners in these areas.

Adding a specially formulated coating of Diffused Nickel to both the inner and outer surfaces of the tube prior to the outer coating greatly increases protection, particulary in high humidity areas.

Carefully specified steel along with a proprietary manufacturing process allows similar mechanical characteristics to traditional copper lines while offering signifcantly increased burst pressures along with better vibration and temperature tolerance as compared to copper.
