Sulong's Mission

Providing Premium-Quality PVC Fabric And Ventilation Duct To Deliver One Turnkey Underground Ventilation Solution

Everything Based on
Environmental Sustainability

With corporate responsibility for global environment protection, Sulong uses raw materials from reliable suppliers and produces PVC fabric with environmentally-friendly processing lines, namely via hot-air welded construction instead of gas or fumes.

No adhesive agent is included during the PVC coating process. While 95% of the flexible ducting manufacturers would use the bonding or adhesive agent during production, which commonly happens, Sulong with exclusive coating technique promises that we grant you pollution-free fabric products.
