Highway signs typically require .080-inch or thicker aluminum to withstand wind loads and impacts, while parking lot or private property signs often use .040-inch sheets for easier handling and cost efficiency.
Do bulk aluminum sheets qualify for LEED or sustainability credits?
Sim. Because aluminum is infinitely recyclable, bulk aluminum sheets with documented recycled content can contribute toward LEED credits in categories such as Materiais & Recursos.
