GBM's heavy duty props are certified in compliance with the DIN EN 1065 standard, which defines one of the toughest standards in the construction industry. Discover what the "quality" of a prop actually means.
In this page:
GBM's heavy duty props are manufactured in compliance with the requirements laid down by the DIN EN 1065 standard, with a certificate awarded by the German university institute (https://www.tum.de/) just like the world's most prestigious companies in the industry, PERI and DOKA.
But what does this actually mean?
The UNI EN 1065 European standard was approved by the CEN on 10 June 1998, and came into force from 1999.
The CEN, an acronym standing for “Comitato Europeo di Normazione” in Italian (European Committee for Standardisation in English, Comité Européen de Normalisation in French, Europäische Komitee für Normung in German) drafted this standard in three official versions, in English, French and German. Translations into other languages used in Europe carried out under the responsibility of a CEN member and notified to the Central Office, have the same status as the original official versions.
CEN members are the national standardisation bodies of the following countries:
Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Island, Italy, Luxembourg, Norway, Holland, Portugal, United Kingdom, Czech Republic, Spain, Sweden and Switzerland.
The standard per se provides for classifying into different classes.
Prospectus 2 of the standard lays down the classification of the prop into classes or models, depending on length at maximum extension (at 50 cm intervals between one model and the other, for example between D35 and D40) and the nominal characteristic resistance.
Classes A, B and C props must comply with the nominal characteristic resistance values required for the respective maximum extensions; classes D and E props instead apply a nominal characteristic resistance to any possible extension length thereof.
The standard outlines the typical definition of a prop and its components.
More in detail, it defines:
The standard indicates which types of steel can be used as source materials (for example type FU steel obtained from de-oxidation is not allowed), it addresses impurities and defects as well as corrosion protection measures.
Partly referring to other pre-existent European standards on materials, bars, pipes and casting, the EN 1065 standard establishes:
The standard provides for defining the configurations of the following elements that the props are made up of, alongside the processes implemented for their manufacture:
The standard also outlines the steps of the prop verification process, specifying the technical data of the properties of the components the prop is made up of, as well as the verification methods with the aim of meeting minimum requirements. Specifications regarding theoretical verifications and test methods regarding physical features of the props are also laid down.
The last paragraph also lays down specifications regarding marking, which must be stamped, or provided in relief, or provided on a steel plate fixed to the prop; the marking must indicate:
