Reflective Sheeting — Classes and Standards in Canada

1) What “class” means (quick overview)

Reflective sheeting classes describe night-time brightness and construction. In plain terms:

• Engineer Grade (EG/Type I): entry level; glass-bead or basic prismatic. Close-range, low-speed areas.
• High-Intensity Prismatic (HIP/Type III–IV): much brighter; prismatic; good all-rounder.
• Diamond Grade (DG/Type IX–XI): maximum brightness and wide observation angles; long approaches and complex backgrounds.

2) Classes compared — brightness & typical use

*Relative brightness is a simple visual scale for buyers; actual candela values depend on colour, entrance/observation angles, and standard test conditions.

3) Colours, durability & printing

• Colours: white, yellow, red, orange, green, blue; fluorescent yellow/green for high conspicuity.
• Durability: EG ≈ 5–7 yrs, HIP ≈ 10 yrs, DG ≈ 10–12 yrs (real life varies with sun, salt and cleaning).
• Printing: use compatible inks/overlaminates; screen or digital traffic-rated systems for outdoor life.

4) Mounting & sign design basics

• Mount to smooth, clean substrates (aluminum, traffic-grade panels). Avoid oil, dust and loose paint.
• Use rounded corners and stainless/aluminum hardware. Back-bracing for larger boards outdoors.
• Face the sign toward the driver’s line of sight; for driveways/garages, tilt slightly to avoid headlight glare bounce.
• In snow areas, raise signs above plow spray; keep posts out of impact paths.

5) Cleaning & handling — don’t kill the retro

• Clean with mild soap + water + microfiber. Rinse well. That’s it.
• No solvents/ammonia/abrasives. They haze or delaminate the reflective layer.
• Pressure washing: keep the nozzle back (≥50 cm) and avoid panel edges and seams.

6) Cold, snow & salt — Canadian realities

• Use prismatic sheetings with proven UV and cold-crack resistance. Salt accelerates edge lift — seal edges on harsh sites.
• Wipe winter film off faces; a dirty reflective sign is basically non-reflective.
• For parking garages, choose non-metallic backers only if moisture won’t warp them — aluminum lasts longest.

7) Work zones vs private property (EN/FR)

• Private property & workplaces: choose class by viewing distance and background clutter; HIP is the safe default.
• Public roads & municipal work: follow the governing manual/spec for colour, size and sheeting class.
• FR/EN: Suivre le manuel applicable pour la route / Follow the applicable manual on public rights-of-way.

8) Inspection & replacement checklist

• Quarterly: clean; check for chalking, cracks, vandal damage and loose hardware.
• Replace faces that are hazy, peeled, or no longer bright at night.
• Log installs and lot codes to track warranty life.

9) Common mistakes to avoid

• Using EG for long sight-lines — drivers won’t see it in time.
• Mounting on rough/dirty boards — adhesion fails early.
• Cleaning with harsh chemicals — instant brightness killer.
