Hot-dip galvanized substrate, hot-dip aluminized-zinc substrate, galvanized aluminum-magnesium substrate.

Substrate requirements for Baosteel’s standard polyester (PE) color-coated sheets:

Hot-dip galvanized substrate must have a total zinc coating weight of 120 g/m² or higher on both sides (Z120);

Hot-dip aluminum-zinc coated substrate: total aluminum-zinc coating weight of 100 g/m² or more on both sides (AZ100);

Hot-dip zinc-aluminum-magnesium coated substrate: total zinc-aluminum-magnesium coating weight of 100 g/m² or more on both sides (AM100).

Base Material Requirements for Baosteel’s High Weatherability (HDP) Color-Coated Steel Sheets:

Hot-dip galvanized base material must have a total zinc coating weight of 180 g/m² or higher on both sides; Hot-dip galvanized aluminum-zinc substrate: total aluminum-zinc coating weight of 150 g/m² or more on both sides (AZ150); Hot-dip galvanized aluminum-magnesium substrate: total magnesium-aluminum-zinc coating weight of 150 g/m² or more on both sides (AM150).

Baosteel’s high-weathering color steel sheets offer a 15-year coating quality guarantee, ensuring the coating will not peel, chalk, crack, or fade within 15 years.
