Purchasing Guide

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

  • In the actual procurement process of smoke exhaust ducts, it is recommended to prioritize confirming key technical parameters such as pipe diameter, material (such as galvanized steel sheet or stainless steel), and temperature resistance performance to ensure compatibility with existing ventilation systems.
  • For different scenarios such as catering kitchens and industrial workshops, smoke exhaust ducts with corresponding anti-corrosion or fire protection levels should be selected based on differences in oil fume concentration or corrosive gas environments.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to balance procurement risks and long-term cooperation stability.
  • For applications in high-rise buildings or enclosed spaces, attention should be paid to the wind pressure bearing capacity and connection sealing of pipelines to avoid affecting smoke exhaust efficiency due to pressure loss.
