Aluminum for construction and architecture
3105 and 1100 sheet, coil and strip 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, flat panels that don't oil-can in the sun, and a surface ready to paint or anodize. These are temper, flatness and surface cleanliness problems, solved at the plant before the sheet reaches your roll former.
Almexa delivers coil and strip at your roll former's width, in mill finish ready for your paint line, with a mill test report per lot.

Frequently asked questions
Which aluminum alloy is best for roofing, 3003 or 3105?
Both work. 3105 is the most common for roofing, gutters and sheet for painting: it contains manganese and magnesium, has equal or slightly higher strength than 3003 and takes paint well. 3003 fits parts with heavy forming or tight bends. Almexa makes both in coil and sheet.
What gauge of aluminum sheet is used for facades?
It depends on the system. As a reference, solid aluminum facade panels usually run 0.080 to 0.118 in (2 to 3 mm), and soffits, gutters and trims 0.020 to 0.040 in (0.5 to 1.0 mm). The final thickness depends on panel size, fixing system and the project's wind load, set with your facade engineer. Almexa makes sheet from 0.020 to 0.157 in (0.5 to 4.0 mm) and plate from 0.157 in (4 mm).
Which aluminum is used for facades?
3105 or 1100 sheet: H14 temper for tight-radius formed parts and H16 for large flat panels with controlled flatness. We make sheet from 0.020 in (0.5 mm); for thinner gauges, coil or strip from 0.0177 in (0.45 mm).
Was Almexa aluminum used in the Soumaya Museum?
Yes. The aluminum hexagon facade of the Soumaya Museum in Mexico City was made with Almexa flat-rolled aluminum.
