    Road & Traffic Sign Types

    Our team can handle a broad range of signs for varying project scopes. We can introduce and install regulatory, warning, guide, hazard, temporary, and directional signs. Rather than using a one-size-fits-all approach, we review your project scope and site plans to confirm the exact signage availability and technical specifications required before work begins.

    Regulatory Signage That Perth Projects Require

    For projects that require strict adherence to traffic laws, we supply and install the regulatory signage Perth developments require. This covers stop and give way signs, speed limit markers, parking controls, and access and movement directives. We advise all civil and government clients that the correct sign series and version must always follow current Main Roads WA (MRWA) or the relevant local authority requirements to ensure site safety and legality.

    Roadwork & Temporary Traffic Signs

    Active work sites require clear, responsive safety measures. We offer full support for temporary roadwork signs and traffic-control devices. We supply and install these in strict alignment with your approved Traffic Management Plan (TMP), ensuring the appointed traffic-management team can safely manage the flow of workers, pedestrians, and passing motorists.

    Car Park & Private-Site Signs

    Clear communication is essential in commercial facilities. We manage the installation of critical car park and private-site signs, including disabled parking (ACROD), reserved bays, loading zone rules, speed limits, entry and exit directions, and pedestrian warnings. To provide a complete end-to-end service, we highly recommend coordinating your signage directly with your car park line marking layout and bollard installation for a cohesive, safe, and highly functional space.

    Posts, Footings & Mounting Systems

    A sign is only as reliable as its mounting system. Our complete installation service includes selecting and supplying appropriate signposts (including galvanised steel), mounting brackets, and fixings. Depending on the sign size, substrate, environmental exposure, and approved installation details, we use secure concrete footings or robust surface-mount methods to withstand Western Australia’s diverse environmental conditions.

    Installation Standards & Site Positioning

    Proper placement is critical to a sign’s effectiveness and legal standing. We focus on optimal visibility, correct mounting height, precise offset, orientation, necessary clearances, and secure fixing. Because site conditions vary widely, we avoid a universal compliance guarantee; instead, we require the latest MRWA, Australian Standard (AS), local council, or specific project specification to govern each job to ensure accurate, compliant positioning.

    Council & Civil Project Support

    We understand the administrative and logistical complexities faced by local councils and large-scale civil developers. Subject to the agreed scope, our team can help interpret sign schedules, review plans and quantities, coordinate staged deliveries, and manage site installation. We can also assist with replacement programs—including spotting and line marking removal for outdated road layouts. We are happy to provide evidence of completed work and schedules, subject to client approval.
