**The way of adhering (Self-Hardening Type)**
It would be difficult to melt the surface of metal materials such as aluminum or aluminum fit, so an adhesive is used in this case. The adhesive should be indurative, which never comes off once binded. Adhesive with viscosity agent is not recommended because this would break off at about 60degree or higher.

Adhesive Strength
Hot-melt type adhesive-vulnerable to heat and moisture is not used, thus duct is strong.

Rigid Structure
It has 6-ply and 12.5mm wire distance to keep very rigid structure performance

Steel Wire
High tensile steel wires are suitable to each size to keep its performance and function perfectly. Copper-coated type, Wire helix distance is 12.5mm pitch, thus pressure drop is low.

Fire Resistance
This aluminum is noninflammable, and it does not coated with PVC, thus in case of fire there is little generation of poisonous gas.
