High strength&lightweight: higher strength than aluminum alloy or steel tube, but much lighter. Also corrosion,water,heat,and fatigue resistance.
The carbon tube is made of pure 3K carbon fiber material. Matte finish is great for surface coating and adhesive bonding applications. And they can be cut to any length with abrasive chop saw.
Widely used in RC model, agricultural equipment, fishing equipment,machinary, automobile, sports equipment, kite, handicraft, tent, windmill, umbrella, decorating parts and so on.
Square carbon fiber tubes are irregular tubes, and the production process is entirely manual by skilled workers, resulting in higher costs.
