Advantages and features of Zinc-Aluminum-Magnesium Steel

ZAM coil is an excellent corrosion-resistant hot-dip Zinc-Aluminum-Magnesium alloy coated steel sheet product.

The product lasts longer in harsh environments, offers built-in trim edge rust protection, and saves money by reducing maintenance.

ZAM is a self-healing, eco-friendly alternative to traditional metal coatings. In addition to the key features mentioned, ZAM:

Excellent alkali resistance - even in direct contact with concrete and mortar

Great alternative to more expensive stainless steel and aluminum

Your post dip batch coated product will be ideal for conversion to cost saving ZAM coated sheet.

Standard of ZAM Steel

ZAM is produced to ASTM A1046/A1046M Type 1 specifications for use where the absolute best rust and cut edge protection is required.

Advantages and Features of ZAM

Longer life than other coating products

Cut edge anti-rust

Thinner coating, more environmentally friendly

Excellent in harsh environments, especially coastal and agricultural environments

No post-dip (batch) galvanizing required

Excellent formability due to coating properties

Cost savings through extended service life and reduced maintenance

Bridging the product gap between thick-coated galvanized steel and expensive stainless steel
