Steel-Flex®: Durable, Flexible &
Long-Lasting Marker Posts
Clear and reliable road markers are essential for safety across Australia’s road network. Delnorth’s Steel-Flex® flexible road markers are primarily designed as guideposts for highways, freeways, and local roads. With the ability to manufacture a wide range of custom marker posts, they also serve various projects, including water, electrical, and telecommunications networks.
Versatility for Multiple Applications
Manufactured in Australia for local conditions, Steel-Flex® posts come in a variety of lengths and colours. They can also be customised with reflective tape, vinyl signage, or other delineation options. This makes them suitable as a flexible delineator post for a wide range of uses, including:
- Mark hazards in areas prone to frequent vehicle impacts
- Highlight infrastructure assets on any terrain or surface, including national highways and rural and regional roads
- Mark the edges of unsealed or partially sealed roads, especially in areas with limited visibility or high traffic
- Support temporary roadworks with rapid deployment options
One solution can cover multiple operational needs, which helps simplify inventory and installation planning.
