Structural rust (affecting structural components which must withstand considerable forces) should be cut back to sound metal and new metal welded in, or the affected part should be completely replaced. Wax may not penetrate spot-welded seams or thick rust effectively. A thinner (less viscous) mineral-oil-based anti-rust product followed by anti ...

Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes ...
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting. [1] [2] [3] It is one of the most common types of conversion coating.
Terne metal can last 90 years or more if the paint is maintained. Terne-coated stainless steel (TCS II or Roofinox), or copper is commonly used to replace terne metal roofs as either material will outlast terne metal. Terne-coated stainless steel roofing can last 100 years or more unpainted; copper roofing can last 50 years or more unpainted ...

Metal roofs can last up to 100 years, with installers providing 50-year warranties. [citation needed] Because of their longevity, most metal roofs are less expensive than asphalt shingles in the long term. [10] Metal roofing can consist of a high percentage of recycled material and is 100% recyclable. [11]
