Factory inspection
Before delivery, the order was inspected at our factory. The inspection covered a load test, a dimensional check and a galvanising thickness check.
- 01Load testCable tray loaded on two supports, deflection measured at midspan
- 02Dimensional checkWidth, depth and material thickness against the drawings
- 03Galvanising thickness checkZinc coating thickness on tray, channel and fittings
01
Load test
A length of cable tray was placed on two supports and loaded with steel bundles that had been weighed on the factory scale.
Deflection was measured at midspan with the load in place. The test was then repeated with a heavier load.
02
Dimensional check
Tray, ladder, channel and fittings were measured against the drawings. Width and depth were checked with a tape, and material thickness with digital callipers.
03
Galvanising thickness check
The zinc coating thickness was measured with a coating thickness gauge on tray, channel and fittings.
