Compliance and Certification
Specification documents for every product we make
Our permanent road signs are manufactured in-house in the UK to the Traffic Signs Regulations and General Directions (TSRGD 2016) and BS EN 12899-1, and carry UKCA marking where the specification calls for it. Our sign posts are hot-dip galvanised steel, certified to EN 10219 and BS EN ISO 1461.
The datasheets, specification sheets and test certificates below are the same documents you will find on each product page. Download them for a specification, tender or site file.
