DURAND places great importance on the safety and reliability of its products. Whether relating to storage buildings,temporary marquees or reception tents there are a number of standards and regulations in force to ensure the safety of persons and equipment.
The CTS Standards for marquees and demountable buildings
Marquees, tents and structures (CTS – Chapiteaux, Tents and structures),intended for the general public, which are leased over short or long term periods, are subject to a strict and specific regulationto counter the risks of fire and panic in establishments open to the public
All of our temporary structures, tents and marquees , are manufactured to withstand winds of up to 100km/h and a snow load of 10kg/m². In the case where these values are reached (exceptional weather conditions), the barnum must be evacuated immediately.
All of our CTS are inspected every 2 years by an Inspection Body (B.V.C.T.S. – marquees, tents and temporary structures inspection body) and benefit from an opinion of structural soundness and stability.
A security register issued by this Inspection body will be provided as well as a certificate of Correct Assembly, a guarantee of safety, quality and reliability.

Regulation NV 65 for permanent and temporary buildings
The NV65 is a set of rules that define the effects of snow and wind on buildings. Here, the NV65 standard concerns therefore our industrial and storage buildings.
The load values vary depending on the different zones, according to a classification carried out on the French territory in 1996.
The regions are therefore listed in accordance with the weather constraints associated with their environment.
SNOW: The French territory is divided into 4 zones.
The map is based on a statistical analysis of the maximum annual depth of snow cover in Europe, converted into loads using a density of snow equal to 150 kg /m3, in 1999.
WIND: The French Territory as well as the overseas departments are divided into 5 zones.
The map represents the base values associated with the reference speed, the values of the normal and extreme base dynamic pressure.
These NV65 rules however no longer have the status of approved standards since the establishment of the Eurocodes.
EUROCODES: European standards for the dimensioning of buildings and marquees
The Eurocodes are European standards for the dimensioning and justification of building structures. They are the approved standards in France.
As regards climatic overloads, involving Snow and wind in particular, please refer to Eurocode (Actions on structures EN 1991).
NF / EN 13782
The NF/EN 13782 standard is a European standard that specifies the safety requirements applicable to all types of temporary covered structures (tents, marquees, hangars or demountable buildings…) with a surface area of over 50m².
These requirements aim to ensure the protection of persons and objects against any damages resulting from the design, manufacturing or use of these temporary structures.
This standard sets out the safety requirements that must be checked during the design, calculation, manufacturing, installation, maintenance, use, inspection and testing of temporary structures.
The QUALIBAT certification is a guarantee of reliability and quality for permanent and temporary buildings
Qualibat is an Association that aims to promote craftsmen and to allow customers to choose a reliable and quality business.
All building craftsmen are eligible for QUALIBAT certification.
The certification labels are awarded by this body to businesses that voluntarily take the steps necessary to obtain them.
The skills and know-how of businesses is assessed on the basis of administrative, financial, legal and technical information. The certifications and labels are therefore awarded on the basis of these criteria, reviewed during annual checks.
