Customer Service

Quality Management and Research Development

CHS pursues customer satisfaction as a primary goal, striving to uphold its commitment to continuously improve the effectiveness of the quality management system. Each year, the quality policy and annual quality objectives are announced following approval by the President, serving as the highest guiding principles for the management system and guiding all employees in their duties.


Quality Certifications

To overcome trade barriers in relevant countries and enhance testing quality and customer confidence in testing data, the Company actively promotes the acquisition of international certifications for quality management systems and product-specific standards. In 2024, to enhance the visibility of its hot-rolled products in green building applications and 3C products using recycled materials, the Company obtained UL 2809 certification for recycled content. By using recycled steel billets, CHS advances its sustainability policy. As of the end of 2024, the quality management systems and product certifications obtained by each plant are as follows:

Certificate Categories Hot Rolling Department Cold Rolling Department Pickling & Galvanizing Department Pipe & Tube Department
ISO 9001 Quality Management System
IATF 16949 Quality Management System      
ISO/IEC 17025 Laboratory Quality Management System

Product Technology Development and Quality Improvement

In response to the increasingly competitive industry environment, CHS is committed not only to enhancing product quality and refining production technologies but also to continuously expanding key niche products across our factories. This strategy aims to increase product added value, develop high-value products, and explore untapped blue ocean markets.


2024 Major Product Technology Development Achievements

Product Category Development Description Primary Use/Outcome
Hot Rolled Development of 1.0 mm Thickness SPHC Products:
Through the refinement of hot-rolled steel strip thickness control technology at the head and tail ends, CHS successfully produced ultra-thin 1.00 mm SPHC hot-rolled steel strips.
This breakthrough overcame the existing lower thickness limit in the manufacturing process, enhancing thickness uniformity and dimensional precision. This advancement facilitates market expansion in high-precision, thin-gauge hot-rolled steel materials, boosting product competitiveness and order flexibility.
Development of EN 10111 DD11 1.20 mm Pickled and Oiled Steel Coils:
In response to customer demand, CHS extended the minimum thickness specification of EDD11 grade pickled and oiled coils from 1.35 mm to 1.20 mm.
Primarily used in downstream sheet cutting applications, the product successfully entered a specific customer's supply chain for thin-gauge pickled steel (approximately 300 metric tons/year), demonstrating the Company’s technical capabilities in customized service and market responsiveness. This also strengthened customer relations and expanded market reach.

Quality improvement achievements in 2024

Product Category Development Description Primary Use/Outcome
Hot Rolled Improvement of Flatness for 5-foot Pickled Plates:
Due to long-term wear of rollers in the pickling line optimized for 4-foot plates, production of 5-foot plates often resulted in edge waviness. Even after secondary leveling, end portions still had to be trimmed, causing yield loss. Since May 2022, an improvement team was established, and after stepwise stratified analysis and enhancement efforts, the trimming rate improved from 5.1% (2022) to 1.42% (2023), and further to 0.59% (2024), demonstrating effective improvement.
The trimming rate decreased from 1.42% in 2023 to 0.59% in 2024, resulting in a reduction of approximately NT$1.75 million.

Intelligent Projects

CHS is advancing artificial intelligence (AI) technologies to encompass applications in smart equipment, intelligent manufacturing, and smart operations. To promote these initiatives, the Company has established the Intelligent Production and Marketing Promotion Committee, focusing on developing intelligent systems across production manufacturing, equipment maintenance, production scheduling, quality management, product sales, occupational safety, and environmental protection. The development projects for 2024 are as follows:
  • 【Establishment of a smart image recognition system for steel billet receiving at the hot rolling mill】
    The manual recording process for steel billet receiving has been replaced with a digital image recognition and storage system.
  • 【Establishment of AI-based image recognition for hot-rolled coil side edges】
    A defect recognition function for coil side edges has been developed to enhance the detection capability of edge defects in hot-rolled coils.
