In collaboration with the Swedish Transport Administration (Trafikverket), we have developed a modern electrical protection canopy for installation above overhead railway lines, designed to replace traditional sheet metal coverings. The protective roof structures also serve as effective suicide prevention barriers, suitable for both railway and road bridges. The structure is engineered based on load calculations for snow, wind, and passing trains. The smooth surface of the Hammerglass panels ensures that dirt and pollutants are largely washed away by rain. The surface treatment also provides 99.96% UV protection, which means that the material will not cloud, discolour or undergo any other change in optical quality over time.
PROTECTIVE SHIELDS & SPLASH GUARDS
A 12 millimeter life-saver
PROTECTIVE SHIELDS SAVE LIVES
Around high-voltage and overhead contact lines the risk of electrical accidents involving serious personal injury is always imminent. The roof construction in high performing Hammerglass conforms to the electrical safety guidelines for electrical protective roof structures for installation on bridges over railway tracks. The design blends in with the surroundings, and at the same time it forms a solid barrier against live conductors.

The angled post system in our robust noise-dampening splash guard for traffic junctions is based on the same structural principle as the design of our overhead electrical protection canopies.
DESIGN AND INSTALLATION
The protective roof construction consists of 12 mm Hammerglass mounted on a system of angled posts bolted to the side of the bridge edge girder. On bridge renovation or in newbuild projects the angled post is installed with base plate beneath the balustrade upright. The roof structure is fatigue-calculated by simulation of the snow- and wind load and the wind load from passing trains, and furthermore satisfies the requirements for noise barriers laid down in the CE standard EN-14388. The solution is watertight and tamper-proof and can be manufactured in execution class EXC2 or EXC3. We are able to undertake complete contracts from dismantling of existing protective structures to the installation of a new electrical protective roof in Hammerglass. Our designers provide finished drawings with fixing solutions in the form of dwg-files.
