In-House Test Capability
Three in-house laboratories – chemical analysis, physical/mechanical and spectrometry: direct-reading spectrometer, universal testing machine (JWL-50KN), eddy-current thickness gauge (ED300), gloss meter (HG60), colour-difference meter (NH310), cupping tester, cross-hatch cutter, Rockwell (PHR-200) and Webster (W-20) hardness testers, conductivity meter, constant temperature/humidity chamber
The dates are stated as they appear on the certificates rather than as a blanket “ISO certified” claim – the registration numbers can be checked at cnca.gov. Current validity is rechecked with the designated manufacturer before order confirmation.The inspection reports date from 2018; recent re-testing can be arranged on request.
We are the export and supply-chain party; the profile is produced by our designated extruding plant. Certificates and test reports are held by that plant, not by this company – scans are confirmed with the quotation, and applicable certificate and authorization copies are provided with the shipment documentation.
