Roofing System For International Conference Hotel
Hanchen Metal has successfully completed the supply of color coated aluminum coil for the roofing system of an International Conference Hotel project. As a global manufacturer and exporter of prepainted aluminum coil, Hanchen Metal was selected to provide advanced solutions to meet the project's demanding architectural and environmental requirements. With the project now completed and in operation, the roofing system demonstrates the superior durability, aesthetic appeal, and long-term performance of our colored aluminum coil products.
Project Overview
The International Conference Hotel project required a large-scale roofing system that could withstand exposure to varying weather conditions including strong winds, humidity, and intense UV radiation. The project owners emphasized the importance of material reliability, long-lasting color stability, and ease of installation. Hanchen Metal provided custom-designed prepainted aluminum coils with both PE coating and PVDF coating options to ensure maximum flexibility for the project.
Most of the roofing materials supplied were designed with a thickness of 1 mm and above, ensuring structural strength while maintaining lightweight characteristics essential for roofing applications.
Weather resistance
Ensuring the roof withstands rain, wind, and UV exposure.
Color retention
Avoiding fading over time to maintain architectural elegance.
Durability & longevity
Minimizing maintenance costs and maximizing life span.
Ease of installation
Requiring high flatness and uniformity for quick construction.

Client Concerns & Our Solutions

Client Priorities
When planning this flagship hospitality development, the hotel's leadership placed strong emphasis on long-term performance and design integrity. The roofing system needed to stand up to heavy rain, high winds, and prolonged UV exposure, all without compromising its structural strength. Equally important was maintaining the building's visual appeal over time, ensuring that the color and finish remained as vibrant and refined as the day of installation. The client also sought a solution that would minimize maintenance expenses over the life of the building, with materials that offered proven durability. Efficiency during installation was another priority, as the project timeline required products with excellent flatness and consistency to enable faster construction.
Our Solution
To guarantee lasting color brilliance and climate resilience, we supplied PVDF-coated aluminum coils engineered to meet the stringent AAMA 2605 standard, providing more than 20 years of proven performance in harsh outdoor conditions. For areas where cost-efficiency was essential, we introduced PE-coated coils that deliver bright, durable finishes with a lifespan of 8~10 years, an ideal balance between aesthetics and budget. Every coil was produced with precise thickness control of at least 1 mm, ensuring structural reliability while keeping the panels lightweight for easier handling. We also offered fully customized color-matching services, giving the architecture team creative freedom without compromise. In addition, our products arrived with exceptional flatness and surface uniformity, allowing contractors to install them quickly and accurately, reducing both time and labor costs.
