RJL specifies, supplies and installs certified perimeter systems — 358 anti-climb weld mesh, palisade, welded steel picket panels, automated gates, turnstiles and vehicle-mitigation barriers — for data centres, defence sites, utilities, transport and critical infrastructure across Victoria.

Where a standard chain-mesh boundary is not enough, aperture size is the control. The 358 profile — 4mm horizontal wires at 75mm centres, verticals at 13mm centres — removes finger and toe holds, denies leverage points and defeats common hand tools, delaying intrusion long enough for detection and response to work.
Australian-made high-tensile zinc-alloy weld mesh: 4mm horizontals at 75mm centres, 3.15mm verticals at 13mm centres. Horizontal corrugations give a contemporary, distinctive appearance while delivering a medium-high security rating — a unique result in the fencing industry.
4mm horizontals at 75mm centres and 4mm verticals at 13mm centres — an anti-climb, anti-cut solution with minimal componentry. The 358 rectangular profile stays highly transparent with minimal visual impact, keeping clear line of sight for surveillance.
Grade 250 or Grade 300 steel, hot-dip galvanised to BS1722-12, assembled in Australia to Australian Standards. Tubular or laser-cut vertical pickets welded into heavy cross-rails give a strong, structural — deliberately intimidating — fenceline.
Corromesh 358® is formed by inserting a continuous wave evenly over the width and length of the weld mesh panel, so panels run continuous in either length or height. The rib design gives maximum strength where a very strong but simple appearance is required, and the corrugations let the fence step evenly over uneven ground for an uninterrupted fence line.
Narrow apertures with spike top deny finger and toe holds while keeping excellent visibility for cameras and surveillance.
Fixings sit in the valley of the panel and are obscured; type and number vary to suit the required security level.
Light, extremely rigid sheets fix to almost any structure — RHS, SHS or existing posts — from the front or rear.
Premium Australian wire with Zalcote zinc-alloy coating, plus an optional zinc-chromate undercoat under powder coat.
Superior corrosion resistance
4×
Lasts up to four times the life of zinc galvanised coatings.
95% zinc / 5% aluminium coated wire has superior corrosion resistance to galvanised wire, especially in marine environments.
Salt-spray testing shows 5% aluminium coated wire lasting three to four times longer than galvanised; in severe marine environments, more than three times longer.
Zalcote coated wire gives superior coating uniformity and alloy-layer integrity — longer life with a smoother surface.
Razar Tape® is designed to prevent intrusion along perimeter barriers — visually confronting, extremely difficult to climb or cut, and shaped to force intruders away from the structure. Manufactured from first-quality spring-steel core wire and galvanised steel strip, it can be added to an existing fence or built into a new one.
Continuous circular coil, adjacent loops clipped around the circumference — self-supporting along the fence top. 300–760mm diameters.
Individual loops fixed flat against the fence or gate with no overhang either side — for boundaries tight to a property line.
Smooth, non-aggressive anti-climb coil with no sharp edges — stronger than standard tape, no public safety risk, and available with low-voltage monitoring.

Core performance features
Systems serving Australian industry since 1988, installed on the country's most sensitive sites.
Structural post and rail design sized to panel height, wind load and threat profile.
Guaranteed weld strengths at every intersection — the failure point attackers target first.
Attractive, low-visual-impact fencelines that suit corporate frontages and surveillance sightlines.
A unique double edge-wire system stiffens panel edges against spreading and levering.
358 panels are manufactured from 95% zinc, 5% aluminium zalcote wire — the ultimate level of corrosion protection, outlasting regular galvanised wire products by two to three times, tried and tested across Australia's harshest environments.
Premium polyester powder-coated finishes are available across the range to meet environmental, architectural and commercial requirements — so a high-security boundary can still match a corporate palette.

RJL specifies high-security fencing, automated gates, bollards and access control for the sites where a breach is not an inconvenience but an incident. Every solution is designed around the site's threat profile, operating hours, compliance obligations and response plan.
Perimeter walls, sterile-zone double fencing, anti-climb rolled toppings and detection-ready mesh for prisons, remand centres, youth justice precincts and police holding facilities — where delay time is measured against response time.
State and federal department buildings, courthouses, service centres, records facilities and secure compounds — specified to agency security standards with documentation, SWMS and cleared crews.
Base perimeters, armouries, fuel and munitions compounds, radar and communications sites — installed by crews carrying police checks, white cards and defence common access cards.
Dual-layer perimeters, anti-cut mesh, generator and substation compounds, and access-controlled vehicle traps for colocation and hyperscale data centres, water treatment plants and telecommunications exchanges.
Electrical substations, pumping stations, gas regulators, water reservoirs and network assets — anti-climb boundaries that keep the public out and inspectors safely in.
Rail corridors, stabling yards, level-crossing pedestrian control, bus depots, airside boundaries and freight terminals, including anti-throw screening to bridges and overpasses.
Container yards, bonded stores, truck marshalling areas and quarantine compounds needing heavy-duty cantilever gates and full vehicle-access control.
Forensic mental-health units, secure aged care and hospital plant compounds where anti-tamper detail and patient safety both matter.
Depots, waste-transfer stations, reserves, sports grounds, playgrounds and public pools — compliant barriers and pool-safety fencing for municipal asset owners.
Boundary security, yard segregation, plant guarding and loading-dock protection for manufacturers and distribution centres.
Child-safe perimeters, pedestrian gates, vehicle access and sports-court enclosures, staged around term dates and bell times.
Basement carpark gates, strata boundaries, gated communities and commercial frontages that lift security and property value together.
Our crews carry police checks, working-with-children checks, white cards and defence common access cards. Full SWMS, licences, insurance certificates and commissioning documentation are supplied before mobilisation.
