Leading to Eco-Friendly JPW

Since 2003, recognizing the global environmental challenges, Zin Hsing Industrial Co., Ltd. began investing in and developing eco-friendly green building materials — JPW Wood-Plastic Composite (JPW WPC). To address the common issues of warping, cracking, and decay found in traditional wood, the company developed a synthetic composite wood. Unlike the standard wood-plastic ratio used in typical WPC products (40% wood to 60% plastic), Zin Hsing formulated an environmentally friendly material with nearly 50% polyethylene and 50% wood powder, in compliance with RoHS standards.

Unlike most WPC manufacturers whose products are commonly used for outdoor decking, furniture, and fences, Zin Hsing has applied its WPC to modular housing construction. A unique patented technology involves forming structural beams and columns with an integrated metal core encased in WPC to enhance strength.

In 2010, when a magnitude 6.4 earthquake struck Jiasian in Kaohsiung, Tainan’s Yujing Junior High School and Jiasian Elementary School were among the hardest-hit. To ensure students could continue their education without interruption, Zin Hsing’s modular WPC housing played a key role. Collaborating with numerous Tzu Chi volunteers and personnel from Ta Chen International Inc., the team quickly assembled 12 temporary classrooms and 2 offices, providing a safe learning environment for over 300 students.

Subsequently, Zin Hsing continued supplying temporary classrooms to schools across Taiwan during new campus construction. By disassembling and relocating existing WPC modular buildings, the company supported faculty and students through their transition period.

Advantages of JPW Wood-Plastic Composite (WPC) Modular Building Structures
  1. Reusability and Cost Reduction
    • Economic Benefits: Components are detachable and reusable, significantly reducing long-term costs.
    • Resource Conservation: Designed for reuse rather than single-use disposal, aligning with the principles of the circular economy.
  2. Environmental Friendliness and Sustainability
    • Eco-Friendly Materials: Made from recycled plastic and wood fibers, WPC reduces the need for virgin timber and decreases plastic waste.
    • Less Construction Waste: Modular components can be reused after disassembly, minimizing construction debris and environmental impact.
  3. Durability and Low Maintenance
    • Weather Resistance: WPC is resistant to moisture, rot, and insects, making it suitable for various climate conditions.
    • Low Maintenance: Unlike traditional wood, it requires minimal upkeep, reducing ongoing maintenance costs.
  4. Simplified Construction Process
    • Factory Prefabrication: Major components of the modular house are manufactured in a factory setting, ensuring consistent quality and reducing on-site construction time.
    • Adaptability to Environment: Easily assembled by manpower even in remote or challenging terrains, making it ideal for rural development or emergency relief housing (e.g., post-disaster shelter).
The Best Choice for Versatile Applications

In addition to use as temporary classrooms, JPW WPC modular houses are also ideal for parent suites, farm cottages, backyard cabins, guardhouses, and outdoor restrooms. In 2024, Taiwan experienced several severe typhoons, most notably Typhoon Doksuri in July, which brought strong winds and heavy rainfall that severely affected central and southern regions. The resulting flooding and infrastructure damage were extensive—yet all modular classrooms constructed by Zin Hsing in southern Taiwan remained completely unaffected.
