Zero Spangle GI Sheet is a hot-dip galvanized steel sheet coated with zinc on both sides,without the spangles that are found on conventional galvanized steel sheets.The zinc coating on surface inhibits the growth of zinc crystals during the curing process, making it impossible to see obvious spangles with the naked eye,provide a smooth and uniform appearance.
Compared with GI steel sheets with spangles, Zero Spangle GI steel sheets have higher aesthetics and application flexibility in building structures, prefabricated houses, home appliances and other fields.
Our zero spangle GI Sheet made from high-quality hot-rolled steel coils,through processes such as pickling, annealing, and galvanizing. In addition, Zero Spangle GI steel sheets also have a higher zinc coating weight, usually between 30g/m² and 275g/m², which helps provide a longer anti-corrosion life.

Galvanized steel is not easy to rust. However,due to its smooth surface, should the galvanised steel sheet incur any damage, the integrity of the protection is compromised, making it prone to rusting.
GI Coil Surface Structure


The galvanized layer of galvanized steel coil forms a barrier that prevents moisture and other corrosive substances from entering the underlying steel, making galvanized steel a resistant and rust-resistant material that can be used in a variety of applications.
GI Steel Advantages
- Anticorrosive:17 years in heavy industrial areas.
- Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
- Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
- Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
- Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
- Save time and energy:Galvanizing process is faster than other coating methods.
Galvanized Steel Quality Inspection
In the industry, the produced galvanized sheet metal are strictly undergoing several testing that is assuring the suppliers in supplying quality. The testing in the industry is conducted by the experts. The tests we usually perform is positive material identification test, hardness test, pitting resistance test, intergranular corrosion test, flattening/flaring test, mechanical test, macro/micro test, chemical test,and third-party inspections are also performed on the demand of the clients.
