Quantum Flex™ Composite
Road Markers
Flexible, fiberglass reinforced composite road markers from QMG provide a safe, low maintenance alternative to metal roadside delineation. The unique design and composition of the Quantum Flex Marker allows for substantial abuse. Quantum flexible markers are designed to withstand repeated vehicle impacts in virtually all weather conditions, flexing upon impact and returning upright. Ideal for general roadside delineation, the Quantum Flex marker reduces your maintenance cost while providing a safer environment for the motoring public. The unique design provides the optimum combination of flexibility and structural integrity for easy installation and allows for a recessed reflective sheeting area that protects the sheeting during impact.
Features & Benefits

Capable of withstanding repeated vehicle impacts, thus greatly reducing the added cost of maintenance associated with marker repair or replacement.

Weather Resistant

Quantum Flex Markers are constructed from a fiberglass reinforced composite which is ultraviolet resistant and temperature stable. They will not become brittle when cold or soften under heat, thereby remaining flexible in virtually all weather conditions.

Lower Maintenance

Solid color impregnated throughout the marker. Never needs painting! Will not fade & crack like thermoplastic or rust & rot like metal or wood.

Easy Installation

Installs fast and easy using industry standard tools. A typical installation takes less than one minute.


Available with or without identification decals, reflective sheeting or letters and numbers. Choose from a variety of colors and sizes to match your application. Small signs can also easily be attached to the marker for increased message requirements.


Strong composite material is 75% lighter than steel & 10 times stronger than typical thermoplastic. Easily stores and transports to the job site.

Fire Resistant

Capable of withstanding small grass fires and controlled ditch burns. Will not soften and melt like common plastic.

Cost Effective

Longer life, lower maintenance and reduced transportation cost. Quantum Markers stay on the job longer with lower overall cost
