When choosing a new pedestrian segregation barrier, it's easy to feel overwhelmed by the number of options available. While leading suppliers like A-SAFE, MPM, and Boplan offer excellent solutions, understanding the differences between their barrier systems is critical to making the right choice for your site.
At Clarity, we’ve helped hundreds of factory and warehouse managers select the right safety barriers based on their layout, risk level, and operational needs. And while we work extensively with MPM’s range, we know there’s no such thing as a one-size-fits-all solution.
This guide compares three of the most widely discussed pedestrian barriers:
A-SAFE iFlex Pedestrian 3 Rail
MPM PED 90
MPM PED 150
We’ll explore their strengths, drawbacks, and suitability for different environments—so you can make an informed decision that enhances workplace safety and reduces long-term costs.
| Barrier Type | Cost per Linear Metre* | Installation Cost (Per Day) |
|---|---|---|
| A-SAFE iFlex Pedestrian 3 Rail | £250+ | £1,000 |
| MPM PED 90 | £150 | £750 |
| MPM PED 150 | £200 | £750 |
*Based on straight-line runs. Costs may vary for gates, corners or bespoke installs.
Installation Notes:
MPM barriers are modular and easy to self-install without voiding warranties.
A-SAFE warranties may be affected by non-certified installation.
Accommodation/travel may apply for external installs.
Not all barriers are tested or certified equally. PAS 13 suggests using 45° impact energy to define system strength, while UNI/TR 11886 takes the lowest-performing point as the overall benchmark.
| Barrier Type | 90° Strength (Joules) | 45° Strength (Joules) | Post Strength (Joules) |
|---|---|---|---|
| A-SAFE iFlex | 5,800 | 11,800 | 2,700 |
| MPM PED 90 | 3,000 | 6,000 | 1,600 |
| MPM PED 150 | 9,087 | 18,174 | 4,100 |
✅ All MPM barriers are independently certified by TÜV and V0 fire rated.
Factory space is valuable. With real estate averaging £1,000/m², footprint matters.
| Barrier Type | Post Diameter | Space Used Per Linear Metre |
|---|---|---|
| MPM PED 90 | 90mm | 0.09m² |
| MPM PED 150 | 150mm | 0.15m² |
| A-SAFE iFlex | 180mm | 0.18m² |
For tighter warehouse layouts, MPM PED 90 is one of the slimmest barriers available globally.
A-SAFE iFlex: Bold, round profiles with high-visibility orange.
MPM PED 90: Flat-faced rails with anti-climb ribbing and square posts.
MPM PED 150: Larger format for heavier-duty zones; retains MPM’s PVC modularity.
✅ MPM’s PVC material allows for slimmer designs without compromising strength.
A-SAFE: Offers a wide range of pre-sized pedestrian gates.
MPM: More flexible on-site. Rails can be cut to precise lengths, allowing exact layouts. Barriers can be retrofitted with gates or upgraded.
For example, the MPM PED 150 can be upgraded to the PED 150 LINK to dramatically increase impact resistance.
All three systems use similar post/rail configurations, but MPM’s design makes installation simpler:
Pre-measured post layouts
On-site rail cutting (in minutes)
Fixings included
Posts and rails slot together easily
MPM barriers also integrate seamlessly with LED projected safety signage for added visibility and pedestrian awareness.
MPM PED 90 and PED 150 are made from V0-rated PVC and have been tested for UV and temperature resistance. If your barriers need to perform externally or in harsh environments, both options are proven to maintain durability and colour over time.
In contrast, A-SAFE barriers use polypropylene blends, which are more combustible and less UV-stable.
Choose A-SAFE iFlex 3 Rail if:
You want a high-profile visual deterrent
You need a broad range of pre-designed gate systems
Choose MPM PED 90 if:
You want cost-effective, space-saving protection
You need flexible layouts with custom lengths
You’re prioritising slim footprint and easy installation
Choose MPM PED 150 if:
You need a heavy-duty solution with upgradable performance
You want a future-proof system with modularity built in
