Bollards are supplied in wide array of sizes with all meeting Leda`s strict quality supply criteria.
Many of the larger and heavier bollards are used for security functions.
Bollards can be supplied to meet just about any vehicle threat. More information is available in the security section of this website.
Industrial bollards are for commercial and industrial premises. Some of the larger sizes can be used for anti-terrorist purposes also.
All are supplied galvanized and supplied in a variety of powercoated or vinyl coated finishes.
The fixed bollards need to be concreted into the ground. See installation recommendations for further details.
Concrete filling does add strength to the bollards. Suprisingly, it is not that much.
Leda`s Finite Element Analysis revealed that the plastic moment of the bollard (point where the bollard starts to fail and bend) is not greatly affected.
Our impact guides do not assume that bollards are concrete filled.The psi of the concrete also greatly effects the strength rating which again increases the number of variables to determine.
Base plate bollards are fixed to the ground using masonry anchors. There are a variety of masonry anchors on the market and Leda can recommend that better anchors will provide far more strength.
No base plate bollards is assumed to be secured though as the masonry anchors rip straight out of the concrete under impact.
The Flip top bollards are not considered security bollards. The reason for this is because a padlock is able to be cut by easily obtainable bolt cutters.
The flip top is a low cost alternative to the Security range which all have internal locking mechanisms.
They are most commonly installed where emergency service access may be required and the padlock allows the Fire department to boltcut the lock and gain access if security is not present.
