This represents 3-5x longer service life compared to ungalvanized steel. The superior performance stems from:

 

● 85μm minimum zinc coating thickness

● Complete coverage including inner surfaces

● High-quality low-carbon steel base material

 

Documented case study: A Southeast Asian client's warehouse structure installed in 2010 shows minimal corrosion after 14 years of coastal exposure.
