Polymer vs Steel Impact Protection: The Complete Guide for Facility Managers in Ireland and the UK
If you manage a warehouse, manufacturing facility or distribution centre in Ireland or the UK, the question of which impact protection material to specify is one of the most consequential decisions you will make for your facility. It affects your people’s safety, your operational costs, and your compliance position.
Most guides on this topic compare the materials in general terms. This one is written specifically for Irish and UK facility managers, including the regulatory environment you actually operate in and is backed by real outcome data from the facilities sector.
How to Select the Right Material for Your Facility
PAS 13, published by the British Standards Institution in association with the UK Health and Safety Executive, is the recognised code of practice for safety barriers used in traffic management within workplace environments. It was developed in response to the scale of workplace transport incidents across the UK and Ireland, and it provides guidance on the barriers suitable for separating vehicles and pedestrians, including their impact resilience, dimensions and appropriate positioning.
PAS 13 covers how barriers should be applied in a facility, and how they should be tested and their performance documented. When a barrier has been tested and certified to PAS 13, it comes with a published impact rating and provides documented evidence that it will perform as intended under a defined load.
Many steel barriers installed in warehouses and industrial facilities carry no certified impact rating and make no performance claims. This means their behaviour during an impact is not guaranteed and cannot be evidenced.
A PAS 13 tested barrier system with a published impact rating provides documented evidence that your protection is fit for purpose. A barrier with no performance certification does not, regardless of what material it is made from.
Steel vs Polymer Barriers on Impact
An Irish Packaging Recycling Company was fined €650,000 at Dublin Circuit Court following a fatal forklift incident at its Finglas plant in October 2025. The company pleaded guilty to two breaches of the Safety, Health and Welfare at Work Act 2005. The incident occurred when an insufficiently trained worker was operating a forklift that overturned, with no supervision in place at the time.
Two Armagh-based companies were prosecuted by HSENI following an incident in which an employee received life-changing injuries when struck by a forklift, and were fined a total of £143,000 across both companies. The HSENI Inspector stated after the hearing that the incident was avoidable and that the principles of managing workplace transport had simply not been applied.
The pattern across these prosecutions is consistent: avoidable incident, inadequate controls identified, significant fine, and consequences that extend well beyond the courtroom. All incidents include insurance implications, reputational damage and the human cost to the team involved, all of which could have been avoided through correct safety and impact protection management.
The HSA’s 2025 Code of Practice for Safe Use of Industrial Trucks sets higher standards than the 2001 guidance it replaced and has made pedestrian segregation a primary inspection focus. When an inspector visits your facility, the question they are asking is not whether you have barriers. It is whether your barriers are correctly specified, correctly positioned and demonstrably fit for purpose for your specific environment.

The Difference Between Steel and Polymer Barriers
Steel barriers are rigid. When a forklift collides with steel, the barrier does not absorb the impact and transfers collision energy through posts and anchors directly into the concrete floor. The barrier can break and crack, and the paint may chip. Then the floor absorbs the force, and both often require attention after significant impacts. The barrier itself is left permanently deformed and typically needs replacing before it can perform its protective function again.
Polymer safety barriers are engineered to work differently. They flex on impact, absorbing and dissipating the energy within the barrier itself rather than redirecting it downward into the floor fixings and concrete slab. Once the impact has passed, the barrier returns to its original position and is ready to perform again without repair or replacement. The vehicle sustains reduced damage, if any at all, and the operation continues without a forced stoppage.
In a busy facility where forklift contact with barriers is a regular occurrence, the cumulative effect of those two different outcomes is substantial over time.
The Cost of Steel Barriers vs Polymer Barriers
Steel barriers can have a lower upfront price. However, that may be the extent of their cost advantage.
Steel Barrier Replacement
Steel barriers are often damaged beyond use after a single moderate impact. Disassembling deformed steel introduces additional safety risks during maintenance. Polymer barriers are designed to withstand repeated impacts over time, and where a component does need replacing, modular systems allow individual parts to be swapped quickly and safely without closing the area.
Floor and Anchor Damage
Repeated impacts into rigid steel barriers can lead to anchor elongation or pull-out, spalling or cracking around baseplates, and cone failure, where anchors tear out a section of concrete during a significant impact. Polymer systems exert significantly lower peak loads on the floor. Over time, avoiding floor repairs alone can represent substantial savings, and when the indirect costs of closing aisles or stopping production during concrete repairs are included, the total expense grows quickly.
Vehicle Damage
When a rigid steel barrier brings a three-tonne forklift to an abrupt stop, damage to forks, wheels, steering or hydraulics is common. Polymer barriers reduce rebound forces and secondary vehicle damage. For facilities with a hired or leased fleet, this is a recurring cost that is frequently overlooked at the point of specification.
Ongoing Maintenance
Steel barriers corrode, require repainting and need regular torque checks on fixings. Some facilities have staff whose primary task is maintaining and repainting steel barriers, which can be a cost that never appears in the original specification but accumulates consistently throughout the life of the installation.
Steel Barriers are Unsuitable for Food, Pharmaceutical and Clean Room Environments
Steel barriers corrode over time, and the paint coatings used to protect them chip and flake on impact. In a food production facility, pharmaceutical manufacturing plant or clean room environment, paint chips and metal particles landing on product lines, packaging surfaces, open containers or sterile equipment are a direct contamination risk.
Polymer barriers are manufactured with colour throughout the material rather than applied as a surface coating. There is no coating to chip, no surface to corrode and no particle contamination risk regardless of how many times the barrier is struck.
If your facility operates under food safety standards, pharmaceutical GMP requirements or any clean room protocol, polymer is not the better option; it's the only appropriate option.
Polybar’s P-FLEX range was specified for exactly this reason at Keohane Foods in Bantry, Co. Cork. The polymer system provides full impact protection at doorways and across the facility without any contamination risk.
Cold Storage Environments
Steel corrodes faster in environments with temperature cycling, condensation and moisture. Paint maintenance is also more disruptive in a temperature-controlled environment where surface preparation is more challenging and cure times for any repair materials are extended.
Polymer maintains its protective properties across a wide temperature range, does not corrode and does not require painting regardless of the conditions it operates in. It is suited to cold storage, outdoor exposed areas, wash-down environments and facilities where chemical products are processed or handled.
Operational Disruptions to Consider
A concern facility managers raise consistently is how much disruption the installation itself will cause.
At Polybar Group, we plan all installations around the operational schedule of your facility. Polymer systems are anchor-fixed with minimal installation time and no major structural modification. In most cases, protection can be installed section by section, keeping the majority of the facility fully operational throughout the process.
If a polymer barrier is later damaged, individual sections can be replaced quickly and, in many cases, allow the area to return to service within minutes rather than the days that concrete repair following steel barrier anchor failure can require.
Making the Right Choice for Your Facility
Based on the research, the regulatory context and the operational realities of Irish and UK industrial facilities, here is a practical framework for the decision:
Choose polymer barriers when:
Your facility has regular forklift traffic and impacts are likely
You operate in food production, food distribution, pharmaceutical or clean room conditions
You operate a cold store or any environment with moisture, condensation or chemical exposure
You want to eliminate ongoing maintenance, repainting and replacement costs
You need to evidence that your barriers are fit for purpose to an HSA or HSE inspector
You want to protect your vehicles as well as your infrastructure
You are protecting racking, structural columns, doorways or production equipment
Choose Steel barriers when:
The application is external perimeter protection against very high-speed heavy vehicles where mass and rigidity are the primary requirement
The zone has genuinely minimal collision potential and serves primarily as a visual deterrent
Budget constraints are severe, and the risk profile of the area is demonstrably low
For the vast majority of internal warehouse, manufacturing and distribution environments across Ireland and the UK, a properly specified and certified polymer system is the appropriate choice.
The Sustainability Factor to Consider
For facilities with ESG reporting obligations or environmental commitments, the lifecycle profile of polymer protection is a relevant consideration. Polymer is fully recyclable, and the manufacturing process carries a lower environmental impact than steel production.
However, this is not a universal property of all polymer materials, so it is worth confirming the recyclability credentials of any specific product being specified.
The material your barriers are made from determines what happens every time a forklift makes contact. The difference between a polymer system that absorbs the impact and returns to shape, and a steel system that deforms and transfers force into your floor, your anchors and your vehicles, is the difference between a non-event and a repair bill that compounds across every shift.
For Irish and UK facility managers, the decision also has a compliance dimension. The HSA and HSE are scrutinising pedestrian segregation and barrier adequacy more closely than at any point in recent years.
Fines for forklift-related fatalities in Ireland reached €650,000 in 2025.
