Road signs are an inseparable part of our daily lives. Without a single road sign, traffic on the roads would be chaotic and dangerous. But have you ever wondered what lies behind the creation of an ordinary-looking yet extremely important element of road infrastructure? In this article, we will trace the entire journey – from the initial design to the placement of the sign on the road in Bulgaria.
Design and planning
The process begins at the road network design stage. Engineers and road safety specialists analyse traffic, road conditions and signage standards. In Bulgaria, Regulation No. 18 on road signage is followed, which determines the type, shape and dimensions of each road sign.
After analysis, a layout plan for the placement of signs is prepared – where and what type should be placed (warning, directional, restrictive, etc.). This stage also includes the requirements of the Traffic Police, municipal authorities and construction supervision.
Selection of materials and standards
The production of each road sign requires precise materials that can withstand weather influences, UV rays, pollution and mechanical damage. In Bulgaria, the following materials are mainly used:
-
High-intensity reflective sheeting (class RA2 or RA3)
-
Aluminium or galvanised steel sheets
-
Powder-coated steel structures for mounting
All materials must be certified to BDS (Bulgarian State Standard) or an equivalent European standard (EN12899-1).
The production process
The production of a road sign in Bulgaria is usually carried out in a licensed factory. The process goes through several stages:
-
Cutting and shaping the base – the metal sheet is cut using CNC machines to the desired shape and size.
-
Surface treatment – the sheet is sanded, galvanised or painted against corrosion.
-
Application of sheeting and symbols – the reflective sheeting is applied by machine pressing, onto which inscriptions, arrows or symbols are placed.
-
Quality control – each piece undergoes visual and mechanical inspection to ensure it meets the standards.
Manufacturing companies, such as those based in Sofia, Plovdiv and Varna, often use automated systems and have ISO quality certificates.
Transport and logistics
Once the signs are ready, they are carefully transported to the installation site. Logistics often involve specialised vehicles, especially if the signs are of considerable size or need to be delivered to remote areas of the country such as the Rhodopes or Strandzha.
Installation of the road sign
The installation of each road sign in Bulgaria is carried out by licensed road signage companies. The steps include:
-
Digging a hole for the foundation
-
Placing a pole or supporting structure
-
Securing the road sign with bolts or welding
-
Fixing with concrete (if required)
Before commissioning, the installation is approved by the respective “Road Safety” directorate of the municipality or API (Road Infrastructure Agency).
Maintenance and control
The life of a road sign does not end with installation. It must be maintained – regularly cleaned, replaced if damaged or worn, and checked for visibility and functionality. By law, road signs must be periodically inspected by authorised bodies.
Importance for safety
Studies show that correctly placed and maintained road signs reduce road accidents by up to 30%. In Bulgaria, this is even more important due to the diverse terrain and climatic conditions. Therefore, investing in quality road signage is not an expense but a measure to protect human lives.
The shape and colour of road signs are an integral part of their function and effectiveness. They create a universal safety language that all road users must recognise without error. To ensure that signage complies with Bulgarian and European standards, always choose certified suppliers and established manufacturers.
SignalPro offers you a complete range of road signs with correct shape, colour, reflectivity and installation, complying with all requirements of Regulation No. 18 and BDS EN 12899-1.
A road sign is much more than a piece of metal with a sticker – it is the result of a complex, professional and responsible process. Every step – from design, through production, to installation and maintenance – requires expertise, adherence to standards and a commitment to road safety. And that is exactly why the life of a road sign deserves respect.
