DELLIOS SA operates based on a modern business model with particular emphasis on strict operation procedures.For this reason, as of 10 years ago, we have applied a quality assurance system on all our machinery. This consistent quality of management is officially recognised by the quality assurance certificate ISO 9001/2000 by the international body TUV.

Recently, DELLIOS® doors acquired a testing certificate from the National Metsovio Technical University, as they passed all appropriate resistance tests, proving once again their excellent composition and premium design.This is a test certificate 62624 from the Nation Metsovio Technical University on the bending of sheets, with the results showing only a 1mm bend for about 300 kp.

(The Greek Standard EN81, 1 and EN81, 2 requires a maximum bending of 15mm for 300kp.)
