Aluminium Flexible Duct

Adhesion Strength;Hot-melt type adhesive-vulnerable to heat and moisture is not used, thus duct is strong. Steel Wire;High tensile steel wires are suitable to each size to keep its performance and function perfectly.Copper-Coated type. Elasticity & Smoothness;In case 10m product is compressed into 60cm for packing and then spread out for use, it would not be compressed again, thus there is little lose of pressure. Fire Resistance;This aluminum is noninflammable, and it's not coated with PVC, thus in case of fire there is little generation of poisonous gas.
