Flexi-T
The World's Toughest Marker Posts – Quick Install For Bitumen
Steel-Flex® Flexi-T is engineered for maximum durability, combining the strength and resilience of Steel-Flex post with a flexible T base for rapid installation on bitumen and other hard surfaces.
The two-piece flexible marker posts are roll-formed from high-performance spring steel, protected by an advanced ArmorGalv® thermal diffusion galvanised coating, and finished with a high-gloss, UV-resistant powder coat. Available in a wide range of colours and compatible with any delineation type, Flexi-T delivers exceptional resilience, visibility, and long-term value even in the toughest conditions.
Features & Benefits
Unmatched Durability:
Roll-formed from high-performance spring steel, Steel-Flex Flexi-T marker posts are protected by an advanced ArmorGalv® thermal diffusion galvanised coating, then finished with a UV-resistant, high-gloss powder coat. This triple-layer protection delivers exceptional corrosion resistance, even after repeated impacts or harsh weather exposure.
Self-Righting Flexibility:
The patented flexible steel design means Steel-Flex Flexi-T posts bend and return upright after impacts or wheel-overs, dramatically reducing replacement and maintenance costs.
Fast, Safe Installation:
The two piece construction allows for rapid installation directly into bitumen and hard ground using mechanical drivers. The ground spike ensures stability and reliability.
Long-Term Performance:
Steel-Flex posts retains at least 75% of its colour and physical properties for 10+ years, even in extreme weather. Fire-resistant up to 140°C, non-flammable, and safe to handle with no sharp edges.
Versatile & Customisable:
Available in a wide range of colours and compatible with all standard delineators and marker post stickers, ensuring compliance and visibility for any project.
Australian Standards Compliance:
Fully compliant with British & European Standard EN 12899–3:2008 and Australian Standard AS 1742.2 and AS/NZ 1906.1.
Applications for Steel-Flex® 1 Piece guide Post
Steel-Flex® 1 Piece Guide Posts are purpose-built for:
Unsealed Roads & Rural Routes
With their ability to withstand repeated impacts and harsh conditions, these posts are ideal for gravel roads, regional highways, and outback tracks where vehicle wheel-overs and environmental extremes are common.
Road Edges & Shoulders
Perfect for marking the edges of unsealed or partially sealed roads, especially in areas with limited visibility or high traffic.
Temporary & Permanent Installations
Their lightweight, one-piece design makes them equally suitable for rapid deployment in roadworks and as a permanent solution for rural infrastructure.
Steel-Flex® Flexi-T Marker Posts are purpose-built for:
Bitumen & Asphalt:
Engineered for secure installation on sealed surfaces, Flexi-T marker posts are ideal for high impact zones on regional routes with bitumen or asphalt. The polyurethane base and ground spike’s robust, flexible design provides consistent asset marking even in high traffic areas.
Hard Ground Installations:
The Flexi-T’s unique base & ground spike make it perfect for extremely hard ground where driving a standard post can be challenging. Flexi-T offers a stable, long-lasting solution for rapid installation, consistent marking and asset identification on compacted or rocky surfaces.
Road Edges & Shoulders:
Flexi-T marker posts can be used on impact zone road edges, to clearly mark assets in higher impact areas.
Temporary & Permanent Installations:
Flexi-T is suitable for both short-term roadworks and long-term infrastructure projects on bitumen and hard ground surfaces.
STEEL-FLEX® FLEXI-T MARKER POST TECHNICAL SPECIFICATIONS
Delnorth Steel-Flex ® is a patented flexible steel delineator post. Steel-Flex Flexi-T may be driven into the ground or road base using a Delnorth designed manual or mechanical driving device. Steel-Flex is capable of withstanding repeated impacts and wheel overs by vehicles with minimal damage to the post or vehicle. Steel-Flex roadside delineator posts comply with:
British & European Standard E N 12899 – 3:2008 & Australian Standard AS 1742.2 and AS/NZ 1906.1
Steel-Flex can retain a minimum of 75% of colour, appearance and physical properties for 10 years even when exposed to extreme weather conditions. They are fire resistant and the powder coating can withstand temperatures of up to 140°C.
Steel-Flex flexible steel delineator posts stand vertical when installed. Testing has shown that the post will not deflect more than 35mm when subjected to wind speeds of 45m / sec. (162 kph) on the front face (convex surface) of the post.
The load required to bend each post length of 1000mm long to an angle of 90° should not be less than 30N. It only requires 5kg pressure to bend a Steel-Flex ® post.
Steel-Flex delineator posts return to vertical automatically after repeated vehicle impacts. They have been tested to 10 impacts from a passenger type vehicle at 100 kph without compromising the integrity of the post. It has been tested to ten wheel over’s at 50kph from a fully laden 42 tonne truck without compromising the integrity of the post.
