Purchasing Guide

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

  • In the actual procurement process of rectangular pipes, it is recommended to prioritize confirming technical parameters such as cross-sectional dimensions, wall thickness, and material to ensure compatibility with the design requirements of ventilation systems or mechanical structures.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually provide more stable delivery capabilities.
  • Rectangular pipes are commonly used in industrial plant ventilation, clean room air supply, and other scenarios. When purchasing, galvanized steel plates or stainless steel materials should be selected according to the pressure resistance level and anti-corrosion requirements.
  • For high flow ventilation scenarios, it is recommended to evaluate the wind resistance coefficient data provided by suppliers and screen enterprises that have long served similar projects based on industry performance.
