We are the most formidable auditors and the most demanding inspectors of our products.
We require the strictest testing of our production process, not just performing ambiguous tests suitable only for adverts and commercial promotions, but also functional tests that are more focused on simulating the real events that products may subjected to over the years.
The resistance and durability of counterframes over time is ensured by the quality of materials and their assembly:
– the top quality galvanized 6/10 and 9/10 plate used to create the counterframe and stainless steel plate at the base are highly resistant to corrosion; – panels with horizontal folds enhance the hardness and strength of structures;
– stapled electrowelded mesh provides considerable tolerance to movement; – rollers have a static load of 120 kg;
The resistance and durability of counterframes were tested at the laboratories of the Certification Authority, “Istituto Giordano”, through a series of product tests:
– Test report no. 285820 “Determination of the tensile strength of rollers for sliding doors” This test, performed to verify the actual static load, demonstrated that the rollers used in counterframes displayed the first signs of weakness when subjected to an average tensile load of 575 kg, which is much higher than the 120 kg required by the company.
– Test report no. 285821 “Impact resistance to soft and hard bodies on the simple interior wall according to the UNI 8201:1981 standard” This test was performed to evaluate the resistance of the product to impacts that could accidentally occur in a building. The test, performed according to the requirements of the UNI 8201:1981 standard, involved subjecting the sample to a series of impacts from a hard body weighing 1 kg (steel ball) and a soft body weighing 50 kg (leather casing containing glass balls); impacts were created by dropping the objects on a pendulum from a height of 200 mm for the hard body and 300 mm for the soft body. Upon completion of the test, the sample was checked and displayed: “no damage”.
– Test report no. 285823 “Mechanical tests on suspending sliding door accessories in accordance with the UNI EN 1527:2000 standard” This test was performed according to the regulations of the UNI EN 1527:2000 standard and aimed to evaluate product resistance over time, particularly for accessory elements such as guides and rollers that are more vulnerable to wear and tear. This included a series of tests that demonstrated product durability over time, even under the harshest usage conditions:
Static resistance. Test during which the guides were loaded with a weight of 120 kg (simulating a door) for 15 min with the following result: “permanent deformation = 0”
Life. Test during which the guide-roller system was subjected to a force of 60 kg (hypothetical weight of a casing) for 150,000 opening and closing cycles. The test was completed with no signs of damage apart from “light marks on the wheels of the rollers”, demonstrating how the product, in the hypothetical case in which it undergoes 14 opening-closing cycles per day, can function without problems for thirty years.
Initial friction test before and after 150,000 cycles. Test that determined the force needed to move the casing before performing the 150,000 opening-closing simulation cycles and after when doors may be overloaded due to wear and tear. The test showed that not only was the force needed to move the casing a mere 0.8 kg but that after 150,000 cycles (which correspond to use over thirty years) the force needed remained unchanged, as demonstrated by the product’s high resistance to wear and tear.
