G90 Galvanized Steel Coils ASTM A653M EN10143 Roofing Steel Coil

Spangle Galvanized Steel Coils G90=Z275g ASTM A653M/ JIS G3302 SGCC / EN10143 Top Quality

Main characteristics of galvanised steel

Corrosion protection: 13 years for heavy industrial areas, 50 years for marine, 104 years for suburban areas and 30 years for urban areas.

Inexpensive: Hot dip galvanising costs less than other coatings.

Reliable: The zinc coating is metallurgically bonded to the steel and forms part of the steel surface, making the coating more durable.

Toughness: the galvanised steel layer forms a special metallurgical structure that can withstand mechanical damage during transport and use.

Comprehensive protection: every part of the coating can be galvanised and is fully protected even in depressions, sharp corners and hidden areas.

Saving time and effort: the galvanising process is faster than other coating methods.
