ALUMINIUM COILS FOR HYDROPHLIC FINSTOCK
flat fin stock has proved its worth in air
conditioners, car radiators and heat exchangers. With the help of high-quality ingots, state-of-the-art gauge and shape control
and precision slitting, we manufacture fin stock that has tight gauge tolerances and excellent slit edges. A tight build-up combined
with internal sound metallurgical properties produce good drawability required for all types of finning;

Packing
GBS flat fin stock is packed on wooden skids in either eye-to-sky or eye-to-wall condition, wrapped in HDPE fabric and
hardboard and strapped with hoop iron. Moisture protection is ensured with silica gel packets and as the final step, the entire
packed product is placed in a wooden cage.
