Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of smoke exhaust ducts, it is recommended to prioritize confirming key technical parameters such as the fire resistance limit and high temperature resistance of the ducts to ensure compliance with building fire safety regulations.
  • In high-frequency application scenarios such as commercial complexes or underground parking lots, it is necessary to choose products with duct cross-sectional dimensions that match the system air volume, while considering installation space limitations.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • Special scenarios such as industrial plants require attention to the anti-corrosion performance of air ducts. It is recommended to choose materials such as galvanized steel or stainless steel based on the composition of the exhaust medium.
