Possibly the strongest security bollards are the range of steel bollards we offer.
All can be manufactured using a 10mm thick wall thickness, and without a lower recess at 168mm diameter will give a spot impact resistance of some 30 tonnes (we recommend you take the advise of a structural engineer and design with this in mind). Various heights and diameters are available from 770mm above ground to 1.2m above ground. We would recommend a minimum 500mm root depth for all these designs. All recesses are fully machined along with the top, giving consistent quality along with their robust design. Bollards are galvanised  and primed prior to the addition of a 2 pack acrylic gloss paint. All bollards can be strengthened further with the addition of our type 199 and 199x ram raid cores.
