INTRODUCTION

ABOUT US STRATEC RT was founded with the purpose to develop new integrative systems which improve the safety of road barriers.

The innovative patents designed by the company allow to solve the critical issues related to the correct installation of road

INTRODUCTION

RESEARCH & DEVELOPMENT

All STRATEC RT solutions are properly dimensioned, universal and compliant with road regulations of the most countries in the

GROUND SLEEVE

world, applicable to all types of barriers to function in any environmental conditions and on any road surface.

➢ Each STRATEC RT technology is conceived, sized, calculated and designed according to the characteristics necessary for a correct application. ➢ Based on the results of the analyzes, a first prototype is created to be tested in the laboratory and multiple functional and material tests are carried out, which must

correspond to the highest safety norms and quality standards.

INITIAL STUDY OF TECNICAL CRITICALITIES ON THE MARKET The most important criticality consists in the constraint at the base of the barrier, which is the connection point with the infrastructure or the ground that determines the correct triggering of the programmed deformation mechanism of the barrier system.

Guardrails on concrete curbs • Standard method of installation on flanges, bolts and chemical anchors does not always guarantee the compliance with the certification conditions;

• maintenance and post-accident restoration very complex and expensive
