Galvalume coil for metal building, roofing, and siding.
AZ50 and AZ55 Galvalume — bare and pre-painted — slit to width or cut-to-length for panel manufacturers and roll-formers across the Midwest.
Galvalume — 55% aluminum / 43.4% zinc / 1.6% silicon on carbon steel — is the working substrate for the metal-building industry. Metal Master supplies it bare (AZ50, AZ55) and pre-painted through the paint-line partners in our multi-mill network. Coil ships slit-to-width for the roll-former or cut-to-length for panel blanks.
