G-iron srl has verified the load capacity of G-iron HE cable trays based on the international standard IEC 61537. The tests were carried out in our lab by using two segments of cable trays, coupled through our standard fastening method. A 1 m long load was applied inside the tray by equally distributing it on its width. The test was repeated by positioning the wooden support structures at a distance of 1.3 m, 1.4 m, 1.5 m, 1.6 m, 1.7 m e 2.0 m between each other.
For the purpose of verifying the endurance of the cable tray when loaded with 90 kg/m, a load of 153 kg/m was actually applied, as per IEC 61537 prescriptions which establish that the load which is being checked should be increased by 1.7 times.

The tests carried out show that G-iron cable trays comply with IEC 61537.
