Advertising structures rely on angles for long-term visibility:
Weather Resistance:
Corten steel angles develop protective patina, lasting 25 years in US highway billboards. Lamar Advertising uses L100×100×10mm angles for this.
Wind Load Capacity:
L125×125×12mm angles with 12mm thickness withstand 120km/h winds, preventing structural failure in coastal areas. Clear Channel employs these in Florida.
Sign Attachment:
Angles with pre-drilled holes simplify graphic installation, reducing changeover time by 40% in European campaigns. JCDecaux uses L80×80×8mm angles for this.
Regional Specifications:
Middle Eastern billboards use hot-dip galvanized angles for sand resistance, while Scandinavian ones prioritize high-tensile angles for snow load support.
