Good packing of Jianglin Steel

Professional packing of multi layer protection to prevent product from rusting,we use cardboard , plastic waterproof and kraft waterproof.
Due to the temperature difference between two country ,the water can inside the coil which casue the products get damage as the pictures.we need to use professional packing.If we just use palstic water proof,the water also can inside the coil,so we need to use multi layer protection with good packing way.The first layer should be cardboard,second is kraft waterproof,the last one is plastic waterproof.
