Quality Control

The quality required of our stainless steel depends on how it will be used. Therefore, we rigorously examine our products using an array of machinery, including tensile testers, hardness testers, eddy current testers, metallurgical microscopes, X-ray fluorescence analyzers, relative permeability meters, and surface roughness meters.

  • Eddy current testers

  • Universal testing machines

  • Vickers hardness tester

  • Metallurgical microscopes

  • X-ray fluorescence analyzer

Environmental Conservation

We do everything in our power to protect our employees and local residents as well as the environment by treating the wood scraps, waste plastic, sludge, waste oil, waste acid, waste alkali, and other waste materials generated during plant operating hours as industrial waste and disposing of it as mandated by law.

  • Wastewater treatment facilities

  • Air conveyance fan

ISO Certification

To reliably deliver high-added-value products that meet our customers’ needs, we acquired ISO 9001 certification, proving that our quality management system satisfies the international standard.
