• 15 million sqm annual production capacity
• 30 years design service life; 20 years without fading in normal outdoor use

How Tiles Are Made

Production runs on computer-controlled temperature, automatic batching and online thickness measurement, so the ASA surface layer and PVC base layer are extruded together at a controlled, even thickness along the full sheet. Green production is standard practice and offcuts are recycled back into the process where the material allows.

Quality Control, Batch by Batch

Every batch is inspected for thickness, colour and strength before release. Colour is checked against the standard colour card so repeat orders match, and thickness is verified against the ordered specification - 2.5mm standard or 3.0mm on request. Sheets that fail any of the three checks do not leave the factory.

Testing & Documents

CE and SGS third-party testing available on request. Tell us which documents your market or project requires when you enquire, and we will confirm what can be provided for your order. Performance figures quoted on this site come from the product manual test data - see the features page. For importer due diligence, read the guide How to choose an ASA roof tile manufacturer in China.
