Fixed vs Removable vs Telescopic Bollards – Which Should I Choose?

If you need to prevent or control vehicle access, a steel bollard can provide a relatively simple solution.

But choosing the bollard itself is only half the decision.

Do you need a fixed bollard that permanently prevents access, a removable bollard that can be lifted out when required, or a telescopic bollard that retracts into the ground?

All three can be used for vehicle access control, but they operate very differently.

At Aremco Barriers, we manufacture and supply fixed, removable and telescopic steel bollards for commercial, industrial and private applications throughout the UK.

In this guide, we'll compare the three types and explain the practical differences you should consider before choosing.

What Is a Fixed Bollard?

A fixed bollard is permanently installed in position.

For a typical root-fixed installation, part of the steel post extends below ground level and is secured within a suitable concrete foundation.

Once installed, the bollard isn't intended to be routinely removed.

This makes fixed bollards particularly suitable where vehicle access through the protected area isn't required.

Typical applications can include:

Building protection
Warehouse entrances
Pedestrian areas
Car park boundaries
Machinery protection
Industrial sites
Service yards
Restricted areas

They can also be installed in rows to create a permanent physical vehicle restriction.

What Are the Advantages of a Fixed Bollard?

The biggest advantage is simplicity.

There is no mechanism to raise, lower or remove during everyday use.

Once correctly installed, the bollard remains in place.

This can make fixed bollards particularly useful where the requirement is straightforward:

Vehicles shouldn't pass this point.

They also don't require somebody to remember to replace them after an authorised vehicle has passed.

What Is the Disadvantage of a Fixed Bollard?

The obvious disadvantage is that the restriction is permanent.

If you later need to bring a delivery vehicle, maintenance vehicle or other authorised vehicle through the area, the bollard can't simply be unlocked and moved.

This is why it's worth considering future access requirements before installing permanent bollards.

A site may not need vehicle access today but could still require occasional access for maintenance or deliveries.

What Is a Removable Bollard?

A removable bollard provides a physical vehicle restriction when required but can be completely removed to create an access route.

Instead of the post being permanently concreted into the ground, a socket is installed below the surface.

The bollard locates into this socket and is secured in position.

When authorised access is required, the bollard can be unlocked and lifted out.

When Are Removable Bollards Useful?

Removable bollards can be particularly useful where vehicle access is required occasionally.

Examples could include:

Service entrances
Private access roads
Commercial premises
Car parks
Maintenance routes
Restricted industrial areas
Emergency or authorised access points

For most of the time, the bollard remains installed and restricts vehicle movement.

When access is needed, it can be removed.

Where Does a Removable Bollard Go When You Take It Out?

Somewhere safe!

It sounds obvious, but this is an important practical difference between removable and telescopic bollards.

Once a removable bollard is taken out of its socket, the complete post needs to be stored.

That means considering:

Its weight
Who will remove it
How far it needs to be carried
Where it will be stored
How frequently this will happen

If access is only required once every few weeks or months, this may not be a problem at all.

If the bollard needs removing several times every day, it may become inconvenient.

What Is a Telescopic Bollard?

A telescopic bollard provides another way of combining vehicle restriction with authorised access.

Instead of removing the complete bollard, the moving post retracts into a casing installed below ground.

When the bollard is required, the inner section is raised into its operating position and secured.

When access is required, it is unlocked and lowered back into its underground housing.

The bollard therefore remains at the installation location rather than having to be carried away.

When Is a Telescopic Bollard Useful?

Telescopic bollards can be particularly attractive where vehicle access is required more frequently.

They may be used for:

Driveways
Commercial entrances
Parking areas
Private access roads
Restricted vehicle routes
Industrial premises

Their main convenience is that there is no separate post to store when the entrance is open.

Which Is Easier to Operate – Removable or Telescopic?

This depends partly on the particular product and the person operating it.

A removable bollard needs to be:

Unlocked
Lifted from its socket
Carried away
Stored
Returned later
Reinserted and secured

A telescopic bollard remains in position and is lowered into its underground casing.

For frequent operation, this can make a telescopic design more convenient.

For occasional access, the simplicity of a removable bollard may be perfectly adequate.

Which Requires the Most Installation Work?

This is where telescopic bollards differ considerably.

A fixed bollard requires an appropriate foundation around its root section.

A removable bollard requires a below-ground socket and appropriate foundation.

A telescopic bollard needs sufficient excavation to accommodate its full underground casing.

This can make telescopic bollards considerably deeper below ground than they appear from the surface.

Why Underground Services Matter

Before installing any root-fixed, removable or telescopic bollard, you need to establish what lies beneath the proposed position.

This is particularly important with telescopic bollards because of the depth required for the housing.

Potential underground services include:

Electricity
Gas
Water
Drainage
Telecommunications
Fibre-optic cables
Other buried services

Never start excavation simply because there is nothing visible at ground level.

Drainage Is Particularly Important for Telescopic Bollards

A below-ground casing is naturally exposed to water from rainfall and surface drainage.

The installation therefore needs to take account of drainage.

Allowing water, dirt and debris to continually accumulate around a telescopic mechanism can cause operational problems.

The same consideration applies to removable bollard sockets, which should also be kept reasonably clear.

What Happens to the Hole When a Removable Bollard Is Removed?

When the bollard is taken out, its ground socket remains in the surface.

Depending on the product, an appropriate cover or socket arrangement may be provided.

The socket should be kept free from stones, dirt and other debris that could prevent the bollard being correctly reinserted.

This should form part of routine maintenance.

Which Type Is Best for a Driveway?

For a driveway requiring regular access, a telescopic bollard can provide a convenient option because it lowers into the ground.

A removable bollard can also work well, particularly where access isn't required constantly and there is a convenient place to store it.

The decision often comes down to a balance between:

Convenience
Installation requirements
Frequency of operation
Available excavation depth
Budget

Which Is Best for an Industrial Site?

All three can have a place on an industrial site.

Fixed bollards may be used around buildings, machinery and areas where vehicles shouldn't enter.

Removable bollards can provide occasional access to service or maintenance areas.

Telescopic bollards can be used where an access route needs to be opened and closed more regularly.

A site doesn't necessarily need to use the same type everywhere.

Can I Mix Fixed and Removable Bollards?

Yes.

This can actually be a very useful arrangement.

Imagine a row of five bollards across an access point.

The outer bollards could be permanently fixed while one or more central posts are removable.

For normal use, the complete row restricts vehicles.

When authorised access is required, the removable posts can be taken out to create a vehicle opening.

This avoids making every bollard removable when only part of the line needs to open.

Can I Mix Fixed and Telescopic Bollards?

Potentially, yes.

The same principle applies.

Fixed posts can provide permanent restriction at the sides while a telescopic bollard provides controlled access through part of the opening.

The most appropriate arrangement depends on the required clear opening and site conditions.

Which Type Needs the Most Maintenance?

Fixed bollards are mechanically the simplest because there are no normal moving parts.

They should still be checked for:

Corrosion
Damage
Foundation movement
Vehicle impact
Deterioration of the protective finish

Removable bollards also require attention to:

Locks
Ground sockets
Covers
Dirt and debris

Telescopic bollards additionally require the moving mechanism and below-ground housing to remain serviceable.

Generally, the more moving components a product has, the more important regular inspection becomes.

What About the Weight?

Weight is particularly relevant with removable bollards.

Someone has to physically lift the post from its socket.

A substantial steel bollard may be perfectly manageable when removed occasionally, but repeatedly moving it can become inconvenient.

Consider who will actually operate the bollard, rather than simply looking at how the system works on paper.

What Finish Can I Choose?

Depending on the particular bollard, options may include:

Galvanised steel
Powder-coated steel
Galvanised and powder coated

Powder coating can also provide greater visibility through contrasting colours and bands.

The available finish depends on the particular product, so check the specification before ordering.

Are These Bollards Crash Rated?

Not automatically.

Fixed, removable and telescopic describe how the bollard operates or is installed, not its tested impact performance.

A substantial steel bollard shouldn't automatically be described as crash rated.

If your project requires a certified vehicle impact rating or hostile vehicle mitigation performance, a specifically tested and certified system should be specified.

Fixed vs Removable vs Telescopic – Quick Comparison

Choose Fixed Bollards If:

You want a permanent vehicle restriction.

Access through the area isn't normally required.

You want a mechanically simple solution.

Choose Removable Bollards If:

Vehicle access is required occasionally.

You're happy to lift and store the bollard when it isn't required.

You want controlled access without a deep telescopic housing.

Choose Telescopic Bollards If:

Access is required more regularly.

You don't want to carry and store a removable post.

There is sufficient below-ground depth and suitable drainage for the installation.

Which One Is Cheapest?

Cost shouldn't be the only consideration.

A simple fixed bollard will generally involve fewer components than a telescopic system, but the complete cost also includes installation.

Ground conditions, excavation, concrete, drainage and making good the surrounding surface can all influence the final cost.

It's better to choose the bollard that works for the site rather than save money initially and discover that it is inconvenient to use.

Ask Yourself One Simple Question

If you're struggling to decide, start with:

How often do vehicles need to pass through this point?

Never or extremely rarely?
Consider fixed.

Occasionally?
Consider removable.

Regularly?
Consider telescopic.

That isn't an absolute rule, but it is a useful starting point.

Frequently Asked Questions

What is the difference between fixed and removable bollards?

A fixed bollard remains permanently installed. A removable bollard locates into a ground socket and can be completely removed when authorised vehicle access is required.

What is the difference between removable and telescopic bollards?

A removable bollard is lifted completely out and needs to be stored elsewhere. A telescopic bollard retracts into a below-ground housing and remains at the installation location.

Which bollard is best for occasional access?

A removable bollard can provide a straightforward solution where access is only required occasionally.

Which bollard is best for frequent access?

A telescopic bollard may be more convenient where access is required regularly because there is no separate post to remove and store.

Do telescopic bollards require drainage?

Drainage is an important consideration because the bollard retracts into a below-ground housing. The installation requirements for the particular product should be followed.

Can fixed and removable bollards be used together?

Yes. Fixed bollards can form the permanent sections of a barrier line while removable bollards create an authorised vehicle access point.

Are Aremco bollards crash rated?

Standard Aremco steel bollards shouldn't be assumed to have a certified crash rating unless a particular product is specifically tested and certified for that performance.
