THE WORLD'S TOUGHEST GUIDE POSTS – QUICK INSTALL FOR UNSEALED SURFACES

Steel-Flex ® is the most durable roadside delineator post available. It is roll formed from a special grade of high-performance spring steel, then protected by an ArmorGalv ® thermal diffusion galvanised coating. Each post is then powder coated to provide a high gloss, UV resistant colour finish. Steel-Flex ® is available in a wide range of colours and can be fitted with any delineation you require. Its unique design and manufacturing process gives Steel-Flex ® exceptionally high corrosion resistance, even after being impacted.

Delnorth Steel-Flex ® is a patented flexible steel delineator post. Steel-Flex ® 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.

Steel-Flex ® has been tested to comply with the following standards:

Impact Resistance (ASTM D – 2794) Adhesion (ISO 2815) 2000 hr Salt Spray (ASTM B – 117)

All faces of the Steel-Flex ® delineator posts are a smooth gloss white powder coat finish to a minimum thickness of 70 microns over a ArmorGalv ® thermal diffusion anti-corrosive protective coating.

Steel-Flex ® is non-flammable

The manufacturer’s name and the month/year date of manufacture with minimum 1 cm high characters, are applied to the concave surface of the post. The recommended installation depth is marked by a 12mm diameter hole punched into the post 40cm from the lower pointed edge. Reflective sheeting is applied to conform with the relevant specifications.

One piece Steel-Flex ® delineator posts are driven into the ground or road base to a minimum depth of 400mm. Dual retention barbs assist to provide post stability, correct alignment and resistance to unlawful removal by hand. Testing has shown, that when installed correctly in average ground conditions, there is a force of over 500kg required to remove the post from the ground.

To maximise the life of the post, it is recommended that a small V shape divot approximately 100mm deep x 100mm long x 105 mm wide, be removed to provide a bend radius when there is a direct wheel-over by a vehicle. This void may be filled with sand if required. Installation instruction sheets are included.

Steel-Flex ® posts can be fitted with all available types of Guide Post delineators and Marker Post stickers complying with AS 1906.1. The posts can be driven in with delineators or stickers attached.

Steel-Flex ® posts have been test conditioned for 2 hours at temperature extremes of -10°C and +60°C.

Result of Steel-Flex ® Heat Resistant Test = Pass (1 second each bend)

Result of Steel-Flex ® Cold Resistant Test = Pass (1 second each bend)

The Steel-Flex ® post has been conditioned for 2 hours at -10°C and no signs of splitting or fracturing when a steel ball at 1kg was dropped from a height of 1500mm.

Result of Steel-Flex ® Steel Ball Test = Pass (1 second each bend)
