HolyPan® Structural Analysis

HolyPan® is a thermoplastic lightweight honeycomb sandwich structure board with PP honeycomb as the core material and glass fiber cloth reinforced polypropylene board as the surface material.

Fiberglass Reinforced Sheet

Lightweight and corrosion-resistant with enhanced strength, rigidity, and impact resistance. The protective film resists moisture, scratches, and wear.

PP Honeycomb Core

Honeycomb geometry ensures excellent load distribution, compressive strength, and insulation. Fully recyclable, eco-friendly, and thermally stable.

Inside HolyCore - Advanced HolyPan® Manufacturing Process

HolyCore produces HolyPan® panels with advanced automated lines.

Each layer "polypropylene panel, fiberglass, and honeycomb core" is precisely laminated for strength and lightness.

Strict quality control ensures consistent performance for global applications.

Features And Advantages Of HolyPan®

Why choose HolyPan ♦ What are its competitive advantages

01/

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%.

02/

High Strength

Impact resistance, combined rigidity and flexibility, and resistance to physical stress and damage.

03/

Easy Assembly

Assembly is extremely convenient and cost-effective. Assembly can be done with screws, hollow rivets, adhesive bonding, or heat-welding.

04/

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.

05/

Weather-Resistant

It is a glass fiber-reinforced thermoplastic material with a wide operating temperature range of -40 to +80°C.

06/

High Chemical Resistance

It is highly resistant to grease, salt water, and common chemicals.
