Test & Quality Control
A linear control flow from incoming steel to dispatch. Limits and acceptance criteria are defined in the order quality plan — not invented for the website.
Process
Control flow
-
01
Incoming Steel
Verification that released strip matches the scheduled thickness.
-
02
Material Verification
Traceability from incoming coil to finished bundle is maintained to the extent defined in the quality plan. Marking and delivery-ticket content follow EN 523 documentation requirements when that standard is invoked.
-
03
Production Control
Profile continuity and forming consistency along the produced length.
-
04
Dimension Verification
Diameter / flat dimension and length checks against the production order.
-
05
Surface Control
Visual review for handling damage or forming defects relevant to use as a sheath.
-
06
Final Inspection
Coupler / duct pairing check where couplers are part of the supply.
-
07
Packaging
Identification, bundling and protection before release to dispatch.
-
08
Shipment
Material and production documents collated as specified for the order.
Inspection areas
