Features and advantages of HolyPan®
Why choose holypan ♦ What are its competitive advantages
Lightweight
Due to its unique honeycomb structure, it has a low density and is extremely lightweight. Using this sheet material in truck body construction can significantly improve the load-to-weight ratio of trucks. For a 4-ton truck, the load-to-weight ratio can be increased by 70%.
High strength
Impact resistance, combined rigidity and flexibility, and resistance to physical stress and damage.
Easy Assembly
Assembly is extremely convenient and cost-effective. Assembly can be done with screws, hollow rivets, adhesive bonding, or heat-welding.
Waterproof and moisture-resistant
This is what sets it apart from wood panels. This material is highly watertight and leak-proof, and even if the surface is damaged, it does not absorb water.
Weather-Resistant
It is a glass fiber-reinforced thermoplastic material with a wide operating temperature range of -40 to +80°C.
High chemical resistance
It is highly resistant to grease, salt water, and common chemicals.
