Aluminum Thickness: 0.06mm or 0.08mm
Aluminum Color: Silver
Packing: 10 sheets/ package
Loading Capacity: 710 sheets/ 40'HQ (packed with plastic bags)
660 sheets/ 40'HQ (packed with cardboard box)
How to make PID Panel Ductwork?
Step 1 - Tracing: outline the duct shapes on the panel.
Step 2 - Cutting: Using manual cutting tools, cut along the panel edges and create 90 degree "V" grooves on the panel.
Step 3 - Gluing: Apply glue to the cutting surfaces of the panels.
Step 4 - Folding: After the glue is cured, fold the sides toward each other to from the straight duct.
Step 5 - Taping: The tape is applied only to the external seams of the duct where the sides of the panel were joined for air-tightness.
Step 6 - Flanging: After applying glue and positioning the steel angle bracket, process to fit the PVC or aluminum invisible flanges.
Step 7 - Reinforcement: reinforce the duct with an aluminum reinforcement bar and G.I. Shaped disks, if necessary.
Step 8 - Sealing: After the duct is assembled, seal all internal joints hermetically with silicone.
Environmental Friendliness of PID Panel Ductwork
This composite duct material is produced using environmentally sustainable raw feedstocks with strict control over harmful chemical compositions.
It achieves zero discharge of toxic volatile organic compounds (VOCs) throughout its service life and maintains an extremely low formaldehyde concentration that meets mainstream international indoor environmental certifications.
Boasting reliable safety performance and excellent health compatibility, the product is well-suited for indoor HVAC ventilation duct systems across all categories of occupied construction projects, covering civil residential buildings, commercial premises, institutional facilities and public service buildings, effectively avoiding indoor air pollution risks caused by ductwork materials.
