Single skin aluminum sheet in thinner material thickness between 1.2mm to 2mm may be a good choice for large-scale projects when the design limits the panel sizes to narrow modules. High-performance coil coated paint finishes offer excellent warranty durations.  In thicker plate up to 3mm, larger format panels can be provided.  Reach out to us, and we can determine whether your project is best-suited to single skin aluminum or the additional benefits of aluminum composite material (ACM).
