Security or manned guarding companies realise the benefits of using their own branded company signs to promote their services and business on existing jobs and sites.

Bespoke printed site signs work not only as a deterrent to would-be trespassers and thieves, but are a great opportunity to promote your business as a professional and forward thinking company.

Printed security signs can be used to draw attention to your company and contact details on fences, gates, site perimeter hoardings, in windows and many other locations.


Yes, Correx® is a fully waterproof and weatherproof plastic which is ideal for the production of all sorts of outdoor printed plastic signs. The signs will last for several years, and can easily be cleaned down with water to freshen them up. The ink won’t fade or run, as it is specially dried onto the surface of the plastic.


Whilst the ‘industry standard’ sized printed Correx® signs of 24 x 18” (610 x 457mm) or approx 24″ x 16″ (600 x 400mm) are the most used sizes of site signs, we regularly get requests for smaller, or very much larger signs.

Working with security companies throughout London, and all of the major cities in the UK, we can produce very large printed Correx® plastic signs of up to 8 x 4’ (2440 x 1220mm) in a single sheet.


All of our printed plastic signs can be supplied complete with holes to allow quick fixing to site fencing. Another popular option is to supply correx sign boards with brass eyelets in each corner. This makes the boards much harder to be pulled down, and offers an even greater extended useful life.


Alongside the obvious name, logo and contact details, a lot of security companies will include images i.e. CCTV cameras, guard dogs.

It is also a great opportunity to enhance your reputation by adding industry accreditations such as SSAIB, SIA Approved, UKAS, BSI, CHAS, NSI and safe contractor approved.


Warning board signage is frequently used to advertise the following;

  • CCTV
  • Manned guarding
  • Guard dogs patrol these premises
  • Security guarding
  • Security services
  • Camera surveillance
  • 24 hour guarding
  • Warning CCTV in operation
  • Protected by
  • Under surveillance


Yes we can produce warning signs on a reflective material, take a look at our reflective signs page for further information.


Yes they can be printed on foamex if requested. Correx® is often chosen to print signs on as it is more cost effective and fully recyclable.


Yes dibond is a good choice for temporary signs that will be displayed for a while. We can print directly onto the dibond surface in full colour.
The signs are weatherproof and very durable.


CCTV or surveillance camera signage is required to alert people to the fact they are being recorded and monitored. The signage should clearly say that CCTV is in operation and what purpose of this is i.e. crime prevention.

In addition, the surveillance or operating company name and contact details need to be clearly displayed should anyone wish to contact them.


Private security has existed for very many years, and has diversified into the hugely varied number of roles and specialties of the Private Security Industry (PSI) of today.

To the general public, the PSI is fairly well defined; it’s the doorman outside the nightclub, the security guards patrolling the local industrial estate, or the in-store security guards at the supermarket. These elements of the industry can be described as the ‘public facing’ private security roles.

In reality, the whole industry is much broader, and encompasses everything from corporate security to private military companies.

It is reported that the Security industry is worth over £7 billion to the British economy. The industry employs in the region of 500,000 people, (compared to around 130,000 Police officers), and forms part of the wider policing family.

The British Security Industries Association (BSIA) is widely recognised as the security industry’s leading trade body in the UK, and is seen as the benchmark of security services. It is an organisation that sets standards for membership, and that gives customers a degree of confidence.

All member companies are subjected to rigorous vetting processes, a minimum of at least two years trading behind them, as well as the ability of demonstrating a good operational and a financially sound track record.

The BSIA’s members are industry professionals ranging in size from global companies to small and medium enterprises, offering a vast spectrum of security related services.

Initially, the concept of the BSIA had identified that there needed to be a benchmark of standards.

At a similar time, a Government body responsible for the policing of the legislation for the licensing and regulation of the security industry came into being: The SIA.

This body created new training standards for the licensing of staff and, extended the three-day Basic Job Training course to include one day of conflict management, two examinations and a thorough vetting process (encompassing a Criminal Records Bureau check to enable an individual to gain a licence) in respect of security officers.


Manned Guarding is one sector of the Security industry, whereby a physical and visible presence is a requirement. Guards or Security officers may be stationed in one work place, or operate a mobile service. It is their role to protect a premise from vandalism, unauthorised access or occupation. Security companies provide Manned guarding security in towns and cities throughout the UK, providing companies with SIA approved personnel.

Today’s Security guards undergo a range of background checks, to vet potential employees to a high standard (BS7858). They are ambassadors of the companies for which they are employed, and undertake an important customer facing role.

To satisfy the requirements of the modern Security Industry, would be Security guards are required to provide a 5 year work history, good communication skills, A SIA licence, a clean criminal record, as well as DBS and financial checks.

There are two types of Manned Guarding or Security officer roles:
Unlicensed security officers are able to be employed directly to work ‘in house’, for example, at supermarkets or retail stores.

Creating a visible deterrent.

A Manned Guarding service, in addition to existing CCTV systems, branded Site Warning Boards and Security posters, will help prevent theft, vandalism and crime on work sites, premises, construction projects, and other employment sites.

A visible presence created by well located and clearly printed Security Signage and patrolling officers warns would-be criminals away, and offers peace of mind to site owners and management.

Buy with confidence from one of the UK’s most established printers of plastic signs

We are specialist printers of corrugated plastic outdoor signs, ideal for Site Security, Surveillance and Warning Board signage. Using both traditional screenprinting and up to the minute high speed digital printing onto plastic, we produce 10,000’s of low cost, waterproof outdoor signs every year.

Since we started our business back in 1987, we have become one of the largest producers of printed correx signs in the country. Our business has grown on the back of great customer service, keen prices and fast deliveries.

As we use both screenprinting and digital printing technology, we can always choose the best printing process to use for your order of printed security signs.

Screenprinting is by far the best method of producing weather resistant and lightfast printing, and you can expect several years of service from Warning signs printed in this way. Silk screen printing on plastic also produces very bright, punchy solid colours, as the ink is specially mixed before printing to colour match what you require.

Also, once a screenprinting machine is set up and running, it will print sheets of plastic (including Correx®) very quickly, which means that the larger the print run, the cheaper the unit cost becomes.

Digital printing is a very new print process with several advantages over screenprinting.

It is ideal for artwork that is made up of lots of different colours, and especially useful for the printing of small logos, tints and tones, as well as full colour pictures and logos.

Because we use both processes, we can choose the best process for your order, to give you the best possible price.

All of our Warning and Security Signage orders are printed on outdoor grade corrugated plastic, well known as Correx®, but also referred to as cortex, corex, cortes, polyflute, corflute and twinflute.

It is a fluted plastic that is made from polypropylene and is 100% recyclable. It is sometimes referred to as polyflute, corrugated plastic or Correx®.

All of our Correx® is specially made in UK mills for us, and meets our tight specifications, to ensure that I t is suitable for your sign order.

We bulk buy from our manufacturers and keep 1000’s of sheets in stock all the time.

This bulk buying means that we can offer you the best prices you’ll find, especially for larger orders of printed plastic warning and site safety boards.
