Most silhouettes are made from 14 gauge to 10 gauge mild steel. Thickness can vary on customer needs and consideration for size, purpose and location for the finished product. Large signs also have a steel square tubing frame construction for increased stability. Various types of legs / frames available for any design. For signs that will be placed near a highway or road – please keep in mind driving speed hinders the ability to read small print, so size needs to be considered. Keep in mind any wind conditions that may also affect your sign. We’d be happy to provide you with options that suit your needs.
