Plain-English guides to specifying, installing and maintaining the products we supply. Written by our team for UK contractors, facilities managers and site engineers.
Guide 01What Is A Crash Barrier?
A crash barrier is a steel safety barrier installed to protect people, buildings and equipment from accidental vehicle impact. In the UK the most common profiles are Armco (corrugated W-beam) and Open Box Beam, both supplied as galvanised rails bolted to driven, cast-in or baseplated posts. Crash barriers are used on roads, car parks, warehouses, loading bays and industrial estates wherever traffic and pedestrians meet.
Guide 02How Does A Crash Barrier Work?
A crash barrier absorbs and redirects impact energy. The steel rail flexes against rigid posts, spreading the force of a vehicle strike across several posts so the vehicle is slowed and pushed back into its lane rather than stopped dead or allowed through. Galvanising protects against corrosion, and post spacing and gauge are chosen to suit the expected impact severity.
Guide 03How To Install A Crash Barrier
Crash barriers are installed by fixing posts at a set centre (typically 1.9m for Armco) using one of three methods: cast-in posts set into fresh concrete, baseplated posts bolted onto an existing slab, or spring posts where some deflection is required. Rails are then bolted to the posts with the matching M16 fixings, and corners and end-pieces are added to close out the run.
Guide 04What Are Armco Barriers?
Armco is the original name for the W-shaped corrugated steel crash barrier profile, now used generically across the UK industrial sector. Armco barriers combine high strength with the ability to deflect on impact, which is why they remain the default choice for vehicle protection in warehouses, car parks, depots and along site perimeters.
Guide 05Open Box Beam vs Armco Barriers
Both profiles do the same job but in different ways. Armco (W-beam) is the lighter, more economical option and is typically used for general site and car park protection. Open Box Beam is a rectangular hollow section that is stiffer, deflects less on impact and is specified where space behind the barrier is tight or where a higher containment level is required.
Guide 06How To Choose Industrial Bollards
Choose bollards on three factors: the threat (low-speed parking nudge vs high-energy ram-raid), the installation surface (concrete slab, tarmac, paving) and the fixing method (surface mounted, bolt-down or cast-in). For warehouse pedestrian protection a 90mm or 114mm bolt-down bollard is usually sufficient; for perimeter and asset protection larger diameter cast-in bollards are used.
Guide 07Warehouse Safety Barrier Guide
A warehouse protection scheme normally combines several products: Armco or polymer barriers along aisles and walkways, column protectors at the base of every upright, corner protection on racking ends and at door reveals, and bollards at high-risk points such as goods-in doors and battery charging areas. Pedestrian segregation handrail completes the layout.
Guide 08Column Protection Explained
Column protection guards structural columns, racking uprights and door frames against forklift and pallet truck strikes. Options range from heavy-duty steel guards bolted into the floor to lightweight plastic wraparound protectors that absorb low-speed impact. Bright yellow finishes also serve as a visual warning to drivers.
