2. Zinc flake coating - Wikipedia

   en.wikipedia.org/wiki/Zinc_flake_coating

   Because electrolytically zinc-plated surfaces provide comparatively little corrosion protection, and in the case of galvanic zinc coatings on high-strength steel (e.g. category 10.9 and 12.9 high-strength bolts) there is a risk of hydrogen embrittlement, the industry needed a better corrosion

3. List of commercially available roofing materials - Wikipedia

   en.wikipedia.org/wiki/List_of_commercially...

   Roofing material is the outermost layer on the roof of a building, sometimes self-supporting, but generally supported by an underlying structure. A building's roofing material provides shelter from the natural elements. The outer layer of a roof shows great variation dependent upon availability of material, and the nature of the supporting ...

4. Self-amalgamating tape - Wikipedia

   en.wikipedia.org/wiki/Self-amalgamating_tape

   Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1] [2] Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant.

5. Flashing (weatherproofing) - Wikipedia

   en.wikipedia.org/wiki/Flashing_(weatherproofing)

   In earlier days, birch bark was occasionally used as a flashing material. [7] Most flashing materials today are metal, plastic, rubber, or impregnated paper. [8]Metal flashing materials include lead, aluminium, copper, [1] stainless steel, zinc alloy, other architectural metals or a metal with a coating such as galvanized steel, lead-coated copper, anodized aluminium, terne-coated copper ...

6. Anodizing - Wikipedia

   en.wikipedia.org/wiki/Anodizing

   The corrosion resistance of aluminium alloys is significantly decreased by certain alloying elements or impurities: copper, iron, and silicon, [5] so 2000-, 4000-, 6000 and 7000-series Al alloys tend to be most susceptible. Although anodizing produces a very regular and uniform coating, microscopic fissures in the coating can lead to corrosion.

7. Galvanization - Wikipedia

   en.wikipedia.org/wiki/Galvanization

   Galvanization (also spelled galvanisation) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. [citation needed]
