Which of the materials sold by Bollards.co.uk would you recommend in certain locations?

Cast iron; this is best suited to pedestrianised, and shopping areas. They also complement a heritage or traditional aesthetic.

Ductile iron; this is best suited to road side locations, shop fronts as well as for anti-ram situations.

Duracast polyurethane; this is best suited to waterside locations, access points (removable low weight) and pedestrian areas.

Mild steel; this is best suited to shopping centres, industrial sites and car parks.

Stainless steel; this is best suited to modern developments, as it provides a sleek and contemporary aesthetic.

Recycled plastic; this is best suited to low budget projects.

Timber; this is best suited to conservation areas, car parks.

Cast aluminium; this is best suited to access points (removable low weight)

What grades of stainless steel do you offer?

Bollards.co.uk offer two grades of stainless steel. These are grade 304 and grade 316. Grade 316 demonstrates a higher chrome content.

When would Bollards.co.uk recommend grade 316?

Grade 316 may be used on marine or waterfront environments. This could help increase longevity and durability in places where the environment is both damp and has a high salt content.

What are the different finishes for stainless steel?

There are various finishes for the stainless steel. These include; bead blasted to various grades (satin), mirror polish and  high polish.

What is the difference between ductile and cast iron?

There is one main difference when it comes to cast and ductile iron. Cast iron is brittle, whereas ductile iron is more "flexible". Ductile iron contains both magnesium and copper, this changes the properties of the bollard, meaning that upon impact the bollard will bend as opposed to snap or shatter on impact.

Is ductile iron more expensive that cast iron?

Due to it's properties, ductile iron is 35% more expensive than cast iron.

Do you recycle any materials?

At both Broxap and Bollards.co.uk we have a strong recycling initative and green ethic. That is why we recycle all cast and ductile iron.

Does cast iron rust?

Cast iron will rust if not maintained. This can happen if the paint is chipped leaving the surface of the bollard exposed.

Removable; Allows periodic access but requires storage when not in use. Additional ground fixing socket may be supplied.

How are logos fitted to the different types of bollard?

Cast iron; integrally cast onto bollard during manufacture.

Polyurathene; usually cast separately and fixed to the bollard by means of an adhesive or drilling and tapping.

How does a ground socket work on a removable bollard?

A steel socket with a hinged lid (sockets approx. 200mm deep) is concreted into the ground. When the bollard is in use, the hinged lid locates on a lug on the bollard and a padlock secures the bollard to the socket. When the bollard is removed the lid fits flush and covers the socket.
