What is hot dip galvanized steel PV mounting structure?

Hot-Dip Galvanized Steel PV mounting structure designed and manufactured by HDsolar, adapt to the specific conditions of each project (terrain, calculation standard, climate conditions, etc.)

What is hot dip galvanized?

Hot dip galvanizing protects steel from corrosion by providing a tough metallurgically bonded zinc envelope, which completely covers the steel surface and seals it from the corrosive action of its environment. The hot dip galvanized coating provides outstanding abrasion resistance.

What is batch hot dip galvanizing?

Batch hot dip galvanizing is a process where prepared items are galvanized by immersing them in molten zinc. The surface of the work is completely covered, producing a uniform coating of zinc and zinc-iron alloy layers whose thickness is determined principally by the thickness of the steel being galvanized.

Does hot dip galvanized protect structural steel?

Corrosion rates for structural steel in these coastal regions vary from 1μm to 1mm per year, while the hot dip galvanized coating can protect structural steel by providing barrier and cathodic protection for over 50 years close to calm seas and over 30 years when the steel is at least 200m from surf beaches.

How long does hot-dip galvanizing take?

When the preparatory procedure is finished, the steel or iron products are ready for hot-dip galvanizing. As previously said, hot-dip galvanizing takes only minutes, however this time can vary depending on the size and shape of the products being galvanized.

How does grit affect a hot dip galvanized coating?

Grit blasting the steel surface to Grade Sa 2½ prior to immersion, using chilled angular iron grit of size G24, roughens and increases the surface area of steel in contact with the molten zinc. This generally increases the weight per unit area of a hot dip galvanized coating by up to 50%.
