The Xpanda Collapsible Barrier is a fully trackless steel security grille with no top or bottom tracks. It can be wall fixed or mounted on steel trolleys for full mobility around a site. Made from high quality tubular steel, phosphate treated and finished in a durable white gloss coating, with black available on request, the Xpanda range covers small doorways through to very large open spans, giving retailers, warehouses and public buildings a practical way to secure or separate an area when needed.

With more than five decades of Xpanda manufacturing heritage and UK supply and installation through Samson Doors, the range provides a strong visual and physical deterrent against opportunist theft, ram raid and smash and grab attacks. It avoids the cost, disruption and floor works associated with tracked shutter systems. Standard stock sizes are held in the UK for quick dispatch, and the system can be fitted in most settings without tracks or floor guides obstructing displays, walkways or fire escape routes.

The Xpanda Trackless Grille Range

Xpanda produce a family of trackless steel grilles built around the same tubular steel lattice, so specifiers can use products from one range across a single site. Samson Doors stock and supply the full UK range, excluding aluminium sliding models:

• Xpanda Saftidor - single or double sash trackless security gate for doorways and openings up to 3150mm wide and 2500mm high.
• Xpanda Saftiwindow - a shorter version of the Saftidor designed for window and serving hatch openings from 900 x 850mm up to 1500 x 1450mm.
• Xpanda Barricade - the heavier scissor lattice shopfront grille used by high profile retailers worldwide for smash and grab protection, available in single, double diamond and partial diamond patterns.
• Xpanding Barrier - a mobile trolley mounted barrier system in steel that spans any width from 1300mm up to 11500mm+ using linked sections, ideal for demarcation and temporary segregation.

All Xpanda grilles share the same core benefits: fully trackless operation, keyless Slamlock technology as standard, epoxy coated steel components, quick installation to brick, block, timber, steel or glazed reveals, and a compact 13 to 20% stack when folded away.

Standard Sizes and Configurations

The Xpanda Saftidor / Collapsible Barrier is available in the following standard stock sizes. Heights can be cut down on site to suit lower openings, and larger or non standard openings are covered by our made to measure service, see below.

Both wall fix into a reveal and face fix on the face of a wall using wall mount, floor mount or combined wall and floor mount kits are supported, with side lock left or right hand options as standard. For larger double sash openings, the same references are available as centre locking pairs spanning 1680mm up to 6300mm.

Key Features and Benefits

Xpanda Saftidor and Saftiwindow - Doors and Windows

The Xpanda Saftidor is the workhorse of the range: a single or double sash trackless grille assembled from tubular steel tubes anchored with Xpanda's patented rivet system, epoxy coated in white or black and supplied ready to hang left or right handed. Standard door sizes run from 840 x 2000mm, Ref A, up to 3150 x 2500mm, Ref P, and each grille arrives with fitting instructions plus access to online video tutorials.

The Xpanda Saftiwindow uses the same tubular construction in a shorter format designed for windows, serving hatches and reception counters. Standard sizes cover 900mm and 1200mm widths at heights of 850mm, 1000mm, 1150mm, 1300mm and 1450mm, plus a 1500 x 1450mm option, ideal for pharmacies, off licences, cash offices, hospital dispensaries and hospitality kiosks.

Both models can be paired with T brackets, deep T brackets, U brackets, shoot bolts, window saddles and aluminium U channel to handle sills, deep reveals and awkward openings, so a Saftidor can be fitted almost anywhere without expensive builders' work.

Xpanda Barricade - Shopfront and High Security Grille

The Xpanda Barricade takes the same trackless principle and scales it up to heavy duty shopfront protection. With its unique scissor lattice pattern, the Barricade has been adopted globally by major retailers as one of the more cost effective smash and grab shopfront grilles in the world, and it carries a manufacturer assurance that it stops smash and grab stock loss or your money back.

Standard Barricade sizes match the Saftidor references from 840 x 2000mm up to 3150 x 2000mm, with a 2500mm high specification available in Ref C, F, G, K and P for taller shopfronts, dock doors and rough sleeper deterrence in doorways and entrances.

For higher risk openings such as tobacco kiosks, jewellery displays, high value electronics stores and cash handling areas, the Barricade Double Diamond variant uses a denser lattice pattern in widths of 1330mm, 1650mm, 1970mm and 2290mm at 2000mm high. A Barricade Partial Diamond option, 2400 x 2500mm, is designed to sit over a shopfront door and can be fitted with a thumb turn lock for full health and safety compliance on designated fire escape routes.

Xpanding Barrier - Mobile Segregation and Access Control

Where a site needs to segregate the public from a working area, cordon off a section during non trading hours or create a temporary partition, the Xpanda Xpanding Barrier is the go to solution. Samson Doors supply the steel Xpanding Barrier in five reference widths, 1300mm, 1600mm, 1950mm, 2400mm and 3150mm, at 2000mm high, and these sections can be linked together on Xpanda's trolley system to span any width up to 11500mm and beyond.

Three trolley options give designers full flexibility:

• Type A Trolley - standard T shaped floor trolley for straight runs.
• Type B Trolley - T trolley with a shoot bolt system for locking the barrier into the floor for higher security.
• Type C / D Trolley - L shaped trolley and 90 degree corner kit for wall abutments, corners and returns where a full T foot will not fit.

Trolleys can be linked with L205 locks, fixed to walls at the ends, hinged for 90 degree returns, or combined with Barricade aluminium lock posts for centre locking runs, giving specifiers the freedom to build a mobile fenced perimeter around plant, stock, exhibits, pop up shops or works in progress and then dismantle it quickly.

Made to Measure and Special Builds

Beyond the standard stock references, Samson Doors offers a full made to measure and special build service on the Xpanda range for openings that fall outside the standard sizes or for clients with specific site or compliance requirements. Bespoke options routinely supplied include:

• Non standard widths and heights beyond the 3150 x 2500mm single sash envelope, including tall openings for atria, warehouse racking aisles and industrial mezzanines.
• Cut down heights to suit low reveals, sloping soffits or existing tracks that cannot be removed.
• Special RAL colour finishes to match corporate identity, listed building consent conditions or retail landlord specifications, in addition to the standard white and black powder coat.
• Enhanced locking packages including Adams Rite type Euro cylinder lock posts with shoot bolts for centre locking doors up to 2500mm, three point Tear Drop Euro locks, double Slamlock upgrades and thumb turn locks with S71 lock protection plates for fire exit compliance.
• Emergency exit configurations designed to satisfy BS 9999 and the Regulatory Reform (Fire Safety) Order 2005 requirements for outward egress from occupied premises.
• Curved and multi angle runs using linked Xpanding Barrier sections with 90 degree corner kits, useful for wrapping around service counters, DDA ramps, escalator landings or curved shopfronts.
• Special installation brackets including deep T brackets, U brackets and stand off brackets, 75mm and 150mm, for sills, mullions, glass reveals and structural steelwork.
• Portable trolley only builds with heavy duty castors for events, exhibitions, film sets, museums and disaster response deployments where nothing can be fixed to the fabric of the building.

Every special build project is surveyed by Samson Doors' UK team from our Northamptonshire head office and London office, with CAD drawings and PDF specifications reviewed against site conditions before manufacture.

Applications and Market Sectors

Xpanda trackless grilles have moved well beyond their traditional role as a lock up shutter. Rising shop theft and organised retail crime, together with a renewed focus on staff safety and public segregation, have made trackless barriers one of the fastest growing categories in physical security. Typical UK applications now include:

• Retail and shopping centres - shopfront closure after hours, in mall unit lock up, tobacco and vape kiosks, spirits aisles, self service checkouts and high value electronics zones. Loss prevention teams increasingly specify Xpanda Barricade grilles as the primary night time defence against smash and grab and ram raid attacks.
• Convenience stores, off licences and pharmacies - overnight closure of counters, dispensaries and stockrooms while allowing air circulation and CCTV visibility.
• Warehouses, factories and distribution centres - segregating pick and pack zones, high value stock cages, hazardous material stores and finished goods holding areas from general operatives and visitors.
• Loading bays and dock doors - secondary security behind roller shutters, allowing doors to remain open for ventilation while blocking unauthorised access.
• Car parks, service yards and forecourts - controlling vehicle and pedestrian access out of hours, protecting fuel and EV charging infrastructure.
• Hospitals, GP surgeries and care homes - segregating drug stores, records rooms and staff only corridors from patients and visitors.
• Schools, colleges and universities - protecting IT suites, science labs, DT workshops and reception areas out of hours.
• Transport hubs - airports, train stations, ports and bus depots use Xpanding Barriers to cordon off retail units, duty free areas and platforms during closures.
• Sports and leisure facilities - gyms, stadia, swimming pools and museums use trackless grilles to control access to bars, shops, plant rooms and exhibits.
• Public buildings, libraries and civic centres - managing crowd flow at events and locking off restricted areas outside opening hours.
• Events, exhibitions and pop up retail - free standing Xpanding Barrier runs on trolleys provide a reusable security perimeter for temporary installations.

Protecting Against Shoplifting and Segregating the Public

UK retail crime has risen sharply in recent years, with the British Retail Consortium reporting daily incidents of violence and abuse against retail workers at 1600. Xpanda grilles address this in two complementary ways.

1. After hours smash and grab protection. A closed Barricade or Saftidor grille turns a vulnerable glazed shopfront into a layered physical defence, deterring casual thieves at the visual stage, denying entry to unauthorised persons, delaying determined attackers long enough for alarm response, and defending stock overnight even when the premises are unstaffed. This Deter, Deny, Delay, Defend principle is the same model used by loss prevention professionals across major UK retail groups.
2. Daytime segregation and public control. During trading hours, Xpanding Barriers and partially closed Saftidors let operators segregate the public from restricted areas, keeping shoppers out of stockrooms, corralling queues around self service tills, protecting staff only corridors, cordoning off cleaning or maintenance zones, and closing individual concessions inside a larger open store. Because the grilles fold away completely, the same opening can be fully open during peak trading and fully closed within seconds when a threat, incident or shift change occurs.

This dual role, a night time barrier and a daytime segregation tool, is the main reason Xpanda trackless grilles are being specified more and more by retailers, facilities managers and security consultants across the UK.

Every Xpanda grille supplied by Samson Doors can be tailored with a full range of locks and accessories:
