From 2022 to 2025, Honrock Railway Transportation Equipment Co., Ltd. delivered approximately 4,995 sets of high-performance rolling blind systems for the new commuter train fleet of Taiwan High-Speed Rail through direct and indirect cooperation channels, covering all carriages along the Taipei to Kaohsiung route. This project realizes the deep integration of subtropical climate adaptation technology and Japanese Industrial Standards (JIS).

I. Project Background

Core Value of the Line

• The Taiwan High-Speed Rail runs through the economic corridor on the west coast of Taiwan Province, China, connecting six metropolitan areas and serving over 300,000 passengers daily, acting as the main transportation artery of the island.

Vehicle Upgrading Requirements

• The Taiwan railway authority launched a replacement plan for 62 new air-conditioned passenger cars, requiring the rolling blind systems to:
▶ Withstand the marine climate with an annual average humidity > 80%.
▶ Endure strong typhoons (maximum wind pressure ≥ 1,500 Pa) and salt spray corrosion.
▶ Achieve zero failure rate within a 15-year design life.

Stringent Standard System

• Simultaneously complying with three certifications: Japanese JIS E 4031, European EN45545 fire protection, and Chinese national standard GB/T 21563 seismic resistance, it becomes a demonstration case of cross-standard integration.

II. Pain Point Analysis and Solutions

1. Mechanism Failure Caused by High Humidity

✅ Pain Points
• Hygrothermal expansion leads to deformation of the rolling blind track exceeding the tolerance (JIS precision requirement: ±0.1mm).
• Coastal salt spray corrodes metal components, causing rust within 72 hours.

✅ Solutions
Climate Adaptive Architecture
▶ Substrate upgraded to 316L marine-grade stainless steel (chloride ion tolerance increased by 5 times).
▶ Innovative humidity-compensated guide rail, automatically adjusting deformation between -0.2mm and +0.3mm.
▶ Nano hydrophobic coating with a surface contact angle > 110° (blocking condensate penetration).

2. Contradiction Between High-Frequency Maintenance and Operational Intensity

✅ Pain Points
• During peak commuting hours, the blind is opened and closed 80 times a day, making the service life of traditional rolling blinds less than 3 years.
• The failure rate surges by 300% due to sand and dust intrusion during typhoon seasons.

✅ Solutions
Extreme Climate Durability Design
▶ Shinkansen-homologous sealing technology (IP68 protection level).
▶ Ceramic-reinforced rope system, reducing friction loss by 90%.
▶ Passed the accelerated aging test simulating Taiwan's climate (1,500 hours equivalent to 15 years).

III. Product Delivery Overview

A total of 4,995 sets of rolling blind systems were delivered for the Taiwan High-Speed Rail upgrading project, with technical penetration embodied in two major aspects:
• Adopting an innovative curved guide rail design to precisely match the arc of high-speed rail windows (tolerance controlled within ±0.5°), overcoming the thermal deformation problem in subtropical high-temperature environments.
• Passed the world's strictest EN45545 HL3 fire resistance and toxicity certification, with a smoke toxicity index of less than 0.1%.

The entire system completed 40 extreme environment verifications at the Zhanghua Experimental Center in Taiwan, with key tests including:

1. Over 1,000 hours of saltspray corrosion testing — simulating the high salt spray environment ofthe Taiwan Strait.

2. 10-level wind pressurevibration table simulation — reproducing the structural stability understrong typhoon conditions.

3. Thousands of opening andclosing fatigue tests — verifying the mechanical durability during peakcommuting hours.

IV. Project Highlights and Cooperative Value

1. Standard Integration Innovation

▶ The world's first rolling blind system for vehicles to achieve mutual recognition of JIS and GB/T dual standards.

2. Localized Agile Services

▶ Customized a traditional Chinese intelligent maintenance system for Taiwan's engineering team.
▶ Completed technical adaptation to mass installation on the first train within 60 days.

3. Green Technology Breakthrough

▶ The base fabric uses recycled PET spun yarn (Oeko-Tex Standard 100 certified).

V. Conclusion

Honrock empowers the Taiwan High-Speed Rail upgrading project with 4,995 sets of high-performance rolling blind systems, demonstrating the full-chain capabilities of Chinese manufacturing in cross-strait technical collaboration, JIS precision manufacturing, and subtropical climate engineering. In the future, it will continue to deepen cooperation with Taiwanese partners, providing a technical foundation for the "zero-compromise reliability" and "humanistic travel experience" of rail transit across the strait.
