Flags · Barricade · Detectable
The Swanson marking catalog covers the visible-layout jobs on a site. Barricade & Safety Tape runs from 2 Mil for quick-deploy weekend cordoning through 3 Mil for week-long jobs, plus 4 Mil buried-line markers for trenching and 6 Mil yellow-and-black hazard stripe for indoor callouts. Detectable Underground Tape carries the APWA color codes (red electric, yellow gas, orange oil, blue potable water, green sewer) in 5 mil PVC with a metallic foil core so an inductive locator reads the run through the backfill, in 2 in. and 3 in. widths on 1000 ft. rolls. Staff Marking Flags plant on a 15 in., 21 in., or 30 in. wire staff with a 2.5 in. x 3.5 in. pennant, in seven colors covering APWA utility codes plus survey pink, lawn-care lime, and high-visibility orange.
