Superior corrosion resistance

In terms of corrosion resistance,
ZAM® is 10 to 20 times better than
hot-dip zinc-coated steel sheets and
5 to 8 times better than
hot-dip zinc-5% aluminum
alloy coated steel sheets.

Superior press
formability

With a harder and smoother coating layer than
hot-dip zinc-coated steel sheets,
ZAM® shows excellent press
formability contributing to
higher productivity.

Cost reduction through eliminating post hot-dip galvanizing process.

ZAM® can contribute to reducing costs
significantly - for instance,
it enables initial cost reduction through
process omission and life cycle cost reduction thanks to its superior corrosion resistance.

Five different types of chromium-free treatments

With the superior corrosion resistance of ZAM®
maintained,five different types of chromium-free
treatments are available to suit various applications.
All of these treatments conform to the environmental regulations, including RoHS and ELV.

Production line

ZAM® is produced with
HCGL in Setouchi Works Hanshin area (Toyo),
1CGL in Setouchi Works Hanshin area (Sakai), and
3CGL in Nippon Steel Nisshin A & C co., Ltd.(Chiba).
