To most of the manufacturers who are working in the steel industry will have this concern about the rust problem during the ocean shipping. It sometimes really give us a headache when the steel products such as steel coils, steel sheets/plates and steel rods that we sell to our customers are rusty. Buyers and sellers trading in this industry of large quantity raw material are usually keep a long relation of reputable and trustworthy cooperation. The less qualified is really doing the harm to our business and the relation that we built for a long time with really hard work and high costs. A large amount of money giving to the buyers as the remedy is inevitable. From the long term, this kind of costs will directly lead to a huge loss of our profits and reputation.

So, what's the effective way of reducing the possibility of this rust problem? Is there any cost-effective solution of making our steel related products better protected and preserved as good for long period?

To this question, the steel coil wrapping machine/ Steel coil wrapper might be the best packaging solution for preseving the quality of steel coils. ( including steel coils, steel strip coils......) This machine is adopting the film winding wrapping methods to the packaging of steel coils. The film winding is performed through the rotating ring which is located on the mainboard of the machine. During the wrapping process, the rotating ring will go through the eye of the steel coils with the film winding through it. To allow the steel coil enter into the wrapping position, there is an opening made on the rotating ring with the matchable width fit to the steel coils.
Generally there are two kind of structure of this steel coil wrapping machine - the downwards style and upwards style. The downwards style machines have the rotating ring opening towards the downside while the opening of the upwards style is towards the upper side. Considering the heavy weights of the steel coils, the steel coil wrapper has the two big supportive rollers which are driven by high standard electrical motor to bear the heavy loads. And the supportive rollers will make the rotation of the steel coil itself during the wrapping, to make the wrapping is evenly placed on the steel coils not one point of it only. The speed of this rotation is adjustable to make the overlapping ratio is changeable for the different requirement based on the user demand and product specification.
                           
The wrapping material of this steel coil wrapper is variant, but packaging material like VCI antirust film and LLDPE stretch film are strongly recommended. The VCI antirust film is able to volatilize anti-rust gas factor which will stop the rusting by accumulating on the steel surface. The LLDPE stretch film has the high self stickness which will make the most airtight wrapping for the steel coils. The wrapped steel coils have the ability to against the erosion by oxygen and the salty environment during the ocean shipping. It can keep your products stay in good condition and preserved for a long time. Making your profits are keeping and promising by yourself.
