Need it for a short-term project? Choose Coroplast This sign is also available on lightweight 4mm Coroplast (corrugated plastic), printed with UV-resistant inks. It is a budget-friendly choice for temporary job sites and short-term projects expected to last a few months. It is not a long-term or reusable sign; when the project wraps up, the sign is done too. For signage you plan to keep and move from site to site for years, choose the aluminum option.
