Audited Supplier Zinc Protect strip enhances roof durability by preventing the discoloration and decay caused by moss, algae, fungus and mold. It can be easily installed on most roof types. As rain water runs along the length of the roof, zinc carbonate produced from the strip, washes across the roof, and inhibits mold growth. The strip will not deteriorate since it is 99.9% pure zinc. Zinc Protect can protect roofs for 20+ years.Zinc Protect meets strict manufacturing and quality control standards not adhered to by other lower quality options.

For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ºC to form an alloy coating of zinc and iron.This galvanized coil has good paint adhesion and weldability.
Wooden tray, iron wrapper, waterproof paper.The steel strips supplied according to the standard are usually applied with common rustproof oil film, which can be swept away with alkali solution. The supplier guarantees that the oiled products will be free from rust under normal packing, transportation, loading and storage conditions within 6 Months, the approved delivery date.
Standard seaworthy export packing:
3 layers of packing, inside is kraft paper, water plastic film is in the middle and outside GI steel sheet to be covered by steel strips with lock, with inner coil sleeve.
