Graphite USA Blanks
DUAL HELIX FACTS!
GRAPHITE-USA's proprietary "Dual Helix" ply construction
produces a rod blank that has outstanding resistance to both crushing
and twisting when compared to the competition.
GRAPHITE-USA's unique construction technique, adapted from our experience in aerospace activities, is superior to the conventional rod blank roll-wrap manufacturing process adopted years ago from the textile industry.
GRAPHITE-USA's two advantages are readily apparent.
GRAPHITE-USA's Dual Helix structure keeps the rod round when heavily loaded during casting or fighting a hooked fish. When conventional blanks are subjected to heavy bending loads, they have a natural tendency to start to go oval because they lack helical reinforcement designed to resist these loads. A rod that starts to ovalize is no longer as stiff as it was when round and will fail by buckling if the line pressure is not backed off. This problem does not occur with GRAPHITE-USA's Dual Helix reinforced blanks. In addition to the phenominal bending strength the Dual Helix construction adds extraordinary crush and nick resistance, making GRAPHITE-USA's blanks the most durable on the market today.
GRAPHITE-USA's second major advantage is the outstanding resistance to twist imparted to the blank thru the Dual Helix design. When casting there are sidewise loads introduced when the fly line is moved out of the fore and aft vertical plane by winds or casting actions. These side loads during fore and aft casts will twist the guides of a rod that does not have the Dual Helix resistance to twist. This twisting deflection is not recovered in the fore and aft casting stroke as casting energy but is lost. Torque loads from twisting rods account for much of the casting arm discomfort and lack of precise fly ine directional control.
The term helical is starting to appear in ads from other rod companies but GRAPHITE-USA's Dual Helix construction is unique and we have used the proven technque for over twenty years.
