Engebold

The Engebold ACM is an aluminum composite panel designed for exterior façades and structural applications, where stability and mechanical strength are decisive. Its structure combines aluminum sheets with a polyethylene core, creating a rigid, stable and reliable panel.

Designed to withstand constant mechanical loads, Engebold provides good impact resistance, excellent flatness and controlled expansion, ensuring reliable performance even in large-format applications.

Its surface treatment helps resist weathering, UV radiation and corrosion. It also supports cutting, machining, bending and drilling, enabling customized solutions with durability and a high-quality finish.

• The panels must be stored in a covered, dry place, protected from direct sunlight before installation.
• Avoid excessive stacking and improper handling that could compromise the integrity of the material.
• During transport, keep the panels fully supported, preventing impacts and deformations.
• Installation must use compatible fastening systems and respect the required gaps for thermal expansion.
• The use of suitable fasteners and sealing materials compatible with outdoor applications is recommended.
• Periodic cleaning should be carried out with water and neutral detergent, using soft cloths.
• Avoid the use of abrasive products, aggressive solvents and high-pressure equipment.
