Passive Safety - Jerol signposts

Structural Properties

The impact absorbing Jerol signposts have
a polymer composite shaft, which consists
of two layers, an inner fibre reinforced
polymer composite and an outer layer
of tough polyolefin.

The posts are manufactured in Sweden by a patented process from glass fibre composite, and comply fully with the latest European standard on passive safety, EN12767. The process is fully computer controlled ensuring that the highest standards of quality control
are maintained.

The construction is extremely durable, being weather and UV-resistant, and service life
is estimated to exceed 60 years. As the shaft material is an electrical insulator, no earth bond is required. The posts are designed and certified to fully comply with the wind load classification and relevant deflection criteria contained in BS EN 12899-1. Design check certificates and data sheets are available on request.

Passive Safety

The sign posts have been extensively crash tested at Helsinki Technical University to EN12767. The university has a reputation as one of the foremost test centres in Europe
and all their work has full 3rd party accreditation. Full test certificates are available.

Doors and Base Compartment

If required a base compartment is provided, 1.0m above ground level. The door is manufactured from stainless steel and is powder coated to match the colour of the post.
The aperture has a rubber seal and the door has a bonded foam lining to provide a watertight seal and to provide good electrical insulation.

Foundations

The posts are available with their own pre-cast foundation - see separate brochure.
Posts can also be installed by the more conventional cast-in-situ concrete sleeved method.

Electrical Connection

To comply with UK regulations, passively safe posts which have an electrical connection must be fitted with a suitable disconnection system. Typical systems are shown in the Jerol Installation Method Statement, which is available upon request.

Jerol Sign Post Calculation Programme

The Jerol/Opta calculation programme, which has been fully verified by independant consultants, enables users to confirm the type and size of posts required for any given sign dimension
and loading criteria.
