“Your customers install thousands of roofing screws weekly. If a screw fails—you hear about it.

Electroplated zinc is cheap, but on high-strength roofing screws, it risks hydrogen embrittlement—delayed brittle fracture that appears months later.

Mechanical zinc plating (per AS 3566.2, Class 3 mechanical deposited) solves both problems：

· Zero hydrogen risk：Cold mechanical process. No acid. No embrittlement.

· AS 3566 Class 3 corrosion protection：Our Class 3 mechanical zinc coating exceeds rigorous Australian standards—passed 1000h salt spray per AS 2331.3.1, humidity, UV, and Kesternich tests.

· Clean threads, fast installation：No pooling, no clogged tips.

For roofing distributors who want repeat orders—not complaints—AS 3566 Class 3 mechanical zinc is the compliant, worry-free choice.”
