SignBold

Signbold ACM is an aluminum composite panel developed especially for visual communication and interior applications, prioritizing light weight, practicality and production efficiency.

With a standard thickness of 3 mm, Signbold features a lightweight, easy-to-process structure, allowing fast cutting, bending and machining, even in smaller-scale operations. Its mechanical performance is suitable for applications where there is no high structural requirement.

The material offers good dimensional stability in interior environments, in addition to a smooth surface that favors visual finishing, printing, adhesive application and cleaning. It is a functional, economical solution aligned with the needs of the graphic and promotional market.

• The sheets must be stored in a covered, dry place on flat surfaces, protected from direct sun exposure.
• Avoid excessive stacking that could cause deformation or damage to the surface.
• During transport, ensure full support of the sheets to avoid warping and impacts.
• During installation, use compatible fastening systems, respecting clearances for thermal expansion, especially in larger applications.
• For permanent outdoor use, it is recommended to evaluate products with paint suitable for high weather exposure.
