Quality Control

Built into Every Step, Not Added at the End

ISO 9001 as Our Quality Guideline

Our factory operates in accordance with ISO 9001 quality management standards, which are applied as guidelines throughout our daily manufacturing processes for industrial doors and loading dock equipment.
From raw material inspection to semi-finished product checks, and from key component testing to final product inspection, every stage follows standardized procedures to ensure consistent quality and reliable performance.
Critical components including steel structures, motors, control systems, and hydraulic units are carefully inspected and tested. Through a systematic quality control process, we ensure each product delivers stable operation, safety, and long-term reliability in real industrial applications.
