Quality Control in Roofing Sheet Manufacturing
Raw Material Inspection
We check incoming materials against relevant specifications, paying attention to thickness, surface condition and material requirements. This helps identify inconsistencies before production begins.
Manufacturing Process Monitoring
Our automated, continuous-process facilities for aluminium-zinc coated and pre-painted steel products help maintain manufacturing consistency. We monitor relevant factors such as coating application, surface preparation, paint finish and sheet dimensions.
Finished Roofing Sheet Inspection
Finished sheets undergo relevant checks for thickness, dimensions, surface finish, coating condition and profile accuracy. These checks help identify visible defects and specification differences before dispatch.
Final Quality Verification
Before dispatch, product details and inspection records can be checked against applicable specifications and order requirements. This helps ensure that the supplied material matches the intended application.
