Sanral Median Grid for U- Channel DISCONTINUED
Although this is a SANRAL specification precast concrete grid, it is not a good product. When a vehicle wheel drives onto this Median Grid, it moves. The results are breakages and grids that are dangerously out of position. This is irrespective of which company manufactured the grids. More ...
Vanstone discontinued the mass manufacture of the Median Grids. To help cover large numbers of breakages along the roads, Vanstone will keep a few in stock for spares. Size: 370mm wide x 85mm deep x 600mm (module) long Mass: 35kg each Static test load (ultimate) across two ribs 60kN Prod. no.: P4-8002

Square Grid for U- Channel
High specification reinforced concrete Grid. Two per channel Concrete Strength 40MPa (ave 28d), Reinforcing: hot dipped galvanized Size: 370mm wide x 135mm deep x 600mm (module) long Mass: 58kg each Test load (ultimate) across two ribs 150kN Prod. no.: P4-8003
Applications: For limited vehicle crossing i.e. occasional traffic moving very slowly. If used as such the grid must be firmly bedded on the channel with strong cement mortar. Rocking movememnt must not be possible. It can carry a lot more than the Median Grid and has a much improved shape.
Contra-indications (Do not use): For heavy vehicles other than rarely and at crawl-speed; high frequency traffic; vehicles moving other than very slowly. Heavy vehicles manoeuvring with the possibility of wheel scuffing.
