Vantell Tenjin Panel is a TPO composite galvanized steel panel designed for energy-saving roofing, siding and exterior cladding applications. It combines a TPO waterproof surface layer with a galvanized steel sheet substrate, providing the waterproofing advantages of TPO with the strength and dimensional stability of metal panels.
Unlike conventional single-layer metal sheets, Vantell Tenjin Panel is designed to provide enhanced roof and wall protection through waterproof surface performance, heat-reflective capability, reduced radiant heat transfer and hot-air weldable TPO seams. The reflective TPO surface helps reduce solar heat gain and can contribute to lower surface temperature and reduced cooling load in hot climates.
With its waterproof TPO surface, galvanized steel support and heat-reflective performance, Vantell Tenjin Panel is suitable for industrial buildings, commercial buildings, prefabricated structures, light steel frame buildings, modular buildings and energy-saving roof and wall systems.

Key Benefits
- Combines TPO waterproofing performance with galvanized steel panel strength.
- Provides a durable exterior surface for roofing, siding and wall cladding applications.
- Supports hot-air welded seam treatment for improved waterproof continuity.
- Reflective TPO surface helps reduce solar heat gain on roof and wall assemblies.
- Helps reduce radiant heat transfer from the roof or wall surface.
- Can help lower surface temperature and reduce cooling load in hot climates.
- Helps improve roof and wall durability compared with ordinary decorative metal sheets.
- Suitable for industrial, commercial, prefabricated and light steel frame buildings.
System Use
Vantell Tenjin Panel should be installed as part of a complete roofing, siding or exterior cladding system. Panel joints, laps, roof edges, ridges, wall transitions, corners, penetrations, fasteners and other critical details should be properly sealed or welded according to project requirements to maintain waterproof continuity.
For roofing applications, compatible flashing details, edge trims, fastener sealing and drainage design should be considered to ensure long-term weather protection. For siding and wall cladding applications, proper substrate support, joint detailing, ventilation and water drainage design should be considered based on the project wall assembly.
Typical Applications
- Industrial roofing systems
- Commercial roof panels
- Exterior siding systems
- Wall cladding applications
- Prefabricated building roofs and walls
- Light steel frame roof and siding systems
- Energy-saving roof and wall renovation projects
- Hot-climate buildings requiring waterproofing and radiant heat reduction
