OUR STRENGTHS

EXPERIENCE

Through the experience of its leaders, JARNIAS PROTECTION brings together more than 30 years of expertise in the manufacturing, supply and installation of nets, tarpaulins and safety systems. With a large equipment fleet and highly qualified technicians, we operate on very diverse worksites, taking on new challenges every day and offering the most suitable solutions for each site-specific issue. Jarnias is one of the benchmark companies for construction firms, industries, and public services or administrations, which regularly call on its technical expertise, for example during natural disasters.

RESPONSIVENESS

Our experience enables us to provide a fast assessment of your needs and implement appropriate solutions within the shortest timeframes to address every situation: accidents, fires, floods, etc. For example: • For PSA, within 72 hours of the client’s request, a safety net was installed under ceiling panels that were falling onto a production unit, allowing operations to resume as quickly as possible. • For the Bouygues group, within 48 hours, the manufacturing and installation of 3,000 m² of protective tarpaulins to resolve a weatherproofing issue.

SAFETY

For JARNIAS, safety is an absolute priority. We ensure it through training, certifications and the qualification of our technicians. We use only certified and approved equipment. PPE (Personal Protective Equipment) monitoring procedures are subject to continuous internal inspections; nets and tarpaulins are labelled and stored in accordance with the strictest standards. The goal is to guarantee everyone’s safety: both around worksites and inside the buildings to be protected, and of course that of our technicians and operatives.

THE STRENGTH OF A GROUP

JARNIAS PROTECTION relies on the specialised expertise of the Group’s various subsidiaries to meet all its clients’ needs. The pooling of technical and financial resources across these subsidiaries provides the Group with strong financial stability, earning it an AA+ rating from the Banque de France.

SUSTAINABLE DEVELOPMENT

JARNIAS PROTECTION is firmly committed to sustainable development through the recycling of used tarpaulins and nets (in partnership with Texyloop), as well as through waste management and monitoring.
