PVC Hollow Roofing Sheet Extrusion Line
+25% Output Efficlency
-15% Energy Consumption
99.6% Stable Operation Rate
Why our sheet extruder stands out
- The hollow structure creates air pockets that significantly reduce heat transfer, keeping buildings cooler in summer and warmer in winter, saving up to 35% on energy costs.
- Premium lines offer ASA co-extrusion, providing outstanding UV protection, color retention, and resistance to harsh weather conditions for decades.
- Advanced extrusion technology ensures precise shaping, smooth surfaces, and consistent density, resulting in durable, warp-resistant.
- Integrated PLC control systems enable real-time monitoring, quick parameter adjustments, and fault diagnostics, reducing downtime and operator dependency for stable, continuous operation.

FAQ
What is a PVC hollow roof tile?
It is a lightweight roofing sheet with internal air cavities (hollow structure) that provide superior thermal and acoustic insulation compared to solid sheets . The hollow design reduces weight while maintaining strength.
What are the main advantages of hollow roof tiles over solid ones?
Key benefits include better heat insulation (air pockets trap heat/cold), significantly lighter weight for easier handling and installation, improved sound insulation, and reduced material costs.
What are typical dimensions?
What extruder models are used?
The SJZ80/156 conical twin-screw extruder (55kW) is common, with output of 300-450 kg/h. Larger models like SJZ92/188 offer higher capacity up to 600 kg/h.
