Spiral ductwork is commonly used for circular ventilation systems. Begin with the supply, return or extract duty, then check air conditions, the environment and the installation constraints. Materials, protective treatment and seam requirements may vary with the application.
For an inquiry, provide diameter, length, required sheet thickness, quantities, connection method and drawings. Include any insulation, sealing or special environment requirements in the schedule for review.
Diameter alone is not enough. Connection compatibility, support arrangements, service access and delivery sections also affect installation. WANJINGDE can help organize the product and fitting scope around the agreed drawings. Final details require written project confirmation.
