Vulcan is known for its Line Marker signs. We use aluminum alloy 5052-H38 a full hard alloy that is made in our Aluminum Mill. This results in the strongest substrate against bending.

The message of our Line Marker signs is screen printed using extensively researched outdoor durable inks and coatings.

Common sizes for rectangle line marker signs are 12” x 9” and 10” x 14”. Cable Route signs are usually 12” x 4”. We can make any size needed!
