our combustion -proof PVC Trunking have strength tenacity ,and are combustion- proof , fireproofing , damp proof , alkalescency- resistant aging- resistant. 1.combustion- proof : as pvc is nonconducting , so our shingfong cable trunking and conduit have no the risk of electrification. 2.Flame retardance , our products will crush out as sons as they are away from the flame , the ability of supply power continually is more stronger than steel tubes 3. Prevent mice and pest: because mice and pests don't like the smell of shingfong cable trunking and conduit ,our products won't be gnawed. 4.Damp proof, alkalescency resistant :shingfong UPVC cable trunking and conduit won't be rusted , and are acid proof alkalescency resistant.. 5.aging-resistant: advanced production technic , which makes shingfong products are aging assistant.
