Safety barriers protect people, vehicles and stock by physically separating forklift traffic from pedestrian routes and shielding racking, machinery and building structure from impact damage. Whether you need to mark out a walkway, guard the end of a pallet racking run or cage off a piece of equipment, the right barrier turns a busy warehouse or factory floor into a safer, better-organised space. Our range covers heavy-duty steel guard rails and flexible polymer impact-protection systems, so you can match the barrier to the hazard.
Types of warehouse safety barrier
Steel guard rails & protective rail systems
The GPC Protective Rail System is built from 100mm welded heavy-duty square tubular steel and finished in high-visibility powder-coated yellow. Each upright sits on a 200 x 200mm square floor plate with pre-drilled ~12mm fixing holes for bolting down to a concrete floor (fixings supplied separately). Double and triple rail configurations are available in 1,220mm, 1,830mm and 2,440mm bay lengths, plus corner sections — and because the corner rail lets you turn the run through 90 degrees, you can build a full protective cage around machinery, control panels or hazardous equipment. Rigid steel guard rails are the right choice for segregating pedestrian walkways, dividing manufacturing cells and protecting fixed plant.
Flexible impact-protection barriers
The McCue SafeStop GuardRail is a modular, floor-mounted barrier system engineered specifically for forklift and pedestrian safety. Its shock-absorbing uprights and flexible rails are designed to absorb and redirect vehicle impacts rather than transmit the force straight into the floor fixings or the structure behind, helping to minimise facility damage and protect people in high-traffic areas. The modular post-and-rail design allows almost any layout, and add-ons such as SafeStop FloorGuard (low-level protection) and the SafeStop Spinner (which deflects glancing blows) tailor the system to specific pinch points. McCue components are independently tested for corrosion resistance, UV stability and impact performance.
Rack-end & upright protection
Pallet racking is most vulnerable at floor level, where the uprights meet forklift and pallet-truck traffic. Guard rails positioned across the end of a racking run, and barriers placed in front of exposed uprights, take the hit before the rack does — protecting the structural integrity of the racking and the loads stored above. For a full explanation of how upright guards, end barriers and floor rails work together, see our pallet racking protection guide.
How to choose the right safety barrier
Start with the hazard you are managing:
-
Pedestrian segregation — to keep people away from moving vehicles, a continuous run of rigid steel guard rail along the walkway edge gives a clear visual and physical line.
-
Forklift impact zones — at the corners, doorways and aisle ends where vehicles turn or accelerate, a flexible impact-absorbing system like SafeStop reduces damage to both the barrier and the floor.
-
Equipment & machinery — use corner rail sections to build a protective cage around plant, control gear or hazardous installations.
-
Racking protection — fit rail or upright guards at the base of pallet racking exposed to traffic.
Then check the practical details: bay length and whether you need straight runs or corners; floor type and fixing method (most steel systems bolt to concrete); rail height; and finish (yellow powder coat is standard for high visibility). Steel rails offer maximum rigidity for a fixed boundary; polymer impact systems offer repeatable energy absorption where vehicle strikes are likely.
Safety barriers & UK workplace safety
Effective traffic management is a core duty under the Workplace (Health, Safety and Welfare) Regulations 1992 and the wider risk-assessment requirements of the Health and Safety at Work etc. Act 1974. The HSE's long-standing guidance on workplace transport is to separate pedestrians and vehicles wherever reasonably practicable — and physical barriers are one of the most reliable ways to achieve that separation. Well-placed guard rails and impact protection also help you meet your duty to maintain safe access and protect equipment from foreseeable damage. Barriers should be inspected for damage as part of routine site checks, as a struck barrier may need replacing to remain effective.
Why buy your safety barriers from KC Supply
We supply UK industrial sites with handling and storage equipment chosen by engineers, not box-shifters. Our barrier range pairs rigid GPC steel rail systems with the McCue SafeStop flexible impact range so you can protect walkways, racking and equipment from one supplier.

Safety barrier FAQs
What is a safety barrier used for in a warehouse?
A safety barrier physically separates forklift and pallet-truck traffic from pedestrian routes and shields racking, machinery and building structure from impact damage. A continuous run of rigid guard rail gives a clear visual and physical line, which is why barriers are one of the most reliable ways to segregate people from vehicles.
Does UK law require pedestrian barriers in a warehouse?
The law does not prescribe a particular barrier. The Workplace (Health, Safety and Welfare) Regulations 1992 and your wider risk assessment require traffic routes to be safe, and HSE's workplace transport guidance (HSG136) is to separate pedestrians and vehicles wherever reasonably practicable. Physical barriers are a common way of achieving that separation, and your own assessment decides where they are needed.
What is the difference between the GPC steel rail and the McCue SafeStop barrier?
The GPC Protective Rail System is rigid welded steel, which suits a fixed boundary such as a pedestrian walkway, a manufacturing cell or a guard around fixed plant. The McCue SafeStop GuardRail is a modular system with shock-absorbing uprights and flexible rails, designed to absorb and redirect vehicle impacts at corners, doorways and aisle ends.
What is the GPC Protective Rail System made from?
It is built from 100mm welded heavy-duty square tubular steel with a high-visibility yellow powder-coat finish. Each upright sits on a 200 x 200mm square floor plate with pre-drilled fixing holes of roughly 12mm for bolting to a concrete floor. Fixings are supplied separately.
What bay lengths and corner options are available?
The triple rail system is listed in 1,220mm, 1,830mm and 2,440mm bay lengths plus a corner section, and the double rail system is listed in 2,440mm and corner. Because the corner rail lets you turn a run through 90 degrees, you can build a protective enclosure around machinery, control panels or hazardous equipment.
Can safety barriers protect pallet racking?
Yes. Racking is most vulnerable at floor level where the uprights meet forklift and pallet-truck traffic. Guard rails across the end of a racking run, and barriers in front of exposed uprights, take the impact before the rack does. Our pallet racking protection guide explains how upright guards, end barriers and floor rails work together.
Do I need to bolt safety barriers to the floor?
Most steel barrier systems are fixed to a concrete floor using the base plates, and the GPC rail is designed for that. Check the floor type and the fixing method before you buy, and confirm the fixings suit your floor, as they are supplied separately.
How often should safety barriers be inspected?
Barriers should be checked as part of routine site inspections. A barrier that has been struck may need repair or replacement to remain effective, so report and record any impact damage rather than leaving a damaged rail in place.
Barriers should protect routes without blocking them. Our Fire Safety Order 2005 guide explains the duty to keep emergency routes and exits clear.
Barriers protect pedestrians and equipment, but racking uprights take most forklift impact, so read our guides on pallet racking protection and pallet racking inspection under SEMA, EN 15635 and UK law.
