Our unique climate in Southern California can take a toll on our iron fences, as they are constantly exposed to humidity and moisture in the air, making iron victim to the process of oxidation. Over time, your iron fence will show the signs of oxidation with rust patches. Rust is the number one enemy of iron fences, and needs to be removed on the first signs of its appearance. This can be accomplished using a fine wire brush. Make sure to lay a tarp beneath the wrought iron fence to catch flakes, wear gloves, and carefully brush away all points of rust along the fence, paying special attention to the post and joints.
The aluminum profiles for doors and windows are made of 6-series aluminum alloy, and the aluminum-magnesium silicon is the main element of the 6-series aluminum alloy, and each element has a certain range of content. However, the price of various elements is inconsistent, and the lack of precious metal content is a major cause of poor profile quality. Only in strict proportion then can produce aluminum extrusions of excellent quality. The prepared raw materials are placed in an aluminum melting furnace to be melted, slag is discharged, cooled, and then cast aluminum ingots or bars are used for the production of aluminium profiles. If the exhaust is not ideal, the air bubbles in the aluminium profile will cause defects. The aluminium profiles for doors and windows are mainly made of 6063 grade aluminum alloy. If the aluminum extrusion manufacturer uses the national standard 6063 aluminum ingot, it will be guaranteed in terms of raw material quality.
