3105 sheet and coil, mill finish or pre-painted, for facades, ceilings, gutters, roofing, blinds and signage. The hexagon skin of the Soumaya Museum in Mexico City was made with Almexa aluminum.

What a building products manufacturer asks for
Profiles that bend without cracking the paint, flat panels that don't oil-can in the sun, and a color that survives the weather. These are temper, flatness and paint system problems, solved at the plant before the sheet reaches your roll former.
Almexa's pre-painted 3105 is coated in line on our own coil, with adhesion and coating thickness tests per lot.
