Galfan gabion, also called zinc-5% aluminum-mischmetal, Zn-5 Al-MM alloy-coated gabion (to SANS 1580 and
EN 10245-2 and ASTM A975), is one of the most important corrosion resistant gabion. It is widely used for channel lining, coastal protection, revetment and other protective applications.

The Galfan coating are through a two-step coating operation. The first step is zinc coating, which can be hot dipped galvanizing or electric galvanizing. And then the final bath shall contain at least 7.2% of aluminum to prevent depletion during treating.

Advantages of Galfan gabions

• Smooth surface. The coating is continuous, uniform and smooth and without particles and burrs. During using, it is very safe to operate for people and will not hurt workers. Besides, the smooth surface can make the gabion beautiful and bright.
• Better corrosion resistance performance. When the Galfan gabion in the corrosive environments, the aluminum layer will form a oxidation layer to resist the corrosive element, when the oxidation layer is broken, there still have zinc coating to protect the gabion. So it has better corrosion resistance performance than the galvanized gabions.
• High tensile strength. Made of high tensile strength steel wires, the Galfan gabion can supply stability and durability even in the harsh and high impact applications.
• Ecological. The Galfan gabion is non-toxic and no harm to the soil, water and surrounding environments. Additional, the Galfan gabion can ensure the good circulation of air, water and sunlight to ensure the healthily growth of plants.
• High benefit and value. The cost of Galfan gabion is slightly higher than the galvanized gabion, but the better corrosion resistance performance and longer service life make the gabion be worthy for the cost.

Styles of Galfan gabion

Galfan gabion can be made into different styles and specs to suit different applications. They may different in fabrication technology, mesh structure, gabion height and others.
