Do you know which anti-corrosion coating method would give your metal fence the best protection against rust? Read on and discover three rust-prevention methods that fences and gates manufacturers can use when fabricating metal fences. Use this information to select a fence that has the most appropriate rust protection for your residence.
The use of primer paint is the most basic way to protect metal fences from corrosion. The paint is sprayed onto the surface of the metal using a spray pump or aerosol nozzle. Fabricators with small fabrication shops frequently use this corrosion protection method. The biggest downside of this type of rust protection is that it is very hard to apply the paint uniformly on the surface of the metal. Consequently, there will be sections that have thinner layers of paint than other sections. It is very easy for a scratch to remove the paint layer and expose the metal underneath it to agents of corrosion, such as moisture. A fence with this type of rust protection will require frequent maintenance, such as applying fresh paint each time the existing layer is scratched or peels off.
An e-coat is a thin protective layer that is applied by dipping metal fence components in a solution of an organic, paint-like liquid. An electric charge is introduced into the liquid so that the resultant reaction causes the liquid to form a strong bond with the metal surface. The surface of the metal must be cleaned thoroughly in order for a permanent bond to form with the e-coat. The drawback of this method is that the coating forms a thin layer on the surface of the metal. Thus, it is easy to scratch the coating off as you place the metal in the soil. Rust can quickly spread from that exposed part. E-coated metal fences can suffice if you are placing the fence over a concrete wall.
Hot-dip galvanisation refers to a method of protecting metals against corrosion by dipping those metals in liquefied zinc. The zinc reaches every part of the metal and bonds with it. Large manufacturers of metal fences mainly use this method. This method is more costly but it gives the best results. This is because it is possible to apply thick layers of the zinc coating on the metal parts. Furthermore, the zinc coating can heal itself by creeping to cover a scratched surface on the metal component. Galvanised fences are ideal if the components will be anchored in the ground.
As you can see, not all rust protection methods offer the same degree of protection to the components of your metal gate. Pick the protection method that will suit your needs, such as the desired durability and your budget.
