The surface of the aluminium profile is lightly drawn with a smooth hard object, which can leave a white mark on the surface of the profile. If it can be wiped off by hand, it means that the anodised film is not wiped off. If it cannot be rubbed by hand, the anodised film has been wiped off, indicating that the anodised film is poor in firmness and too thin, and the surface quality is poor. The average film thickness of the anodised aluminium profile for doors and windows needs to be at least 15um.

Cast Iron vs. Wrought Iron Fencing: What’s the Difference?

Cast iron is known for its strength and resistance to wear and tear, making it an excellent choice for outdoor applications. Unlike wooden fences that can rot, warp, or be eaten by pests, cast iron requires minimal maintenance over the years. It can withstand harsh weather conditions, including rain, snow, and ultraviolet rays, without deteriorating. Even if the paint chips, the underlying metal remains intact, allowing for easy touch-ups that can restore its original beauty. When properly maintained, cast iron picket fences can last for generations, making them a worthy long-term investment.

As sustainability becomes a priority for many homeowners, cast iron fencing presents an eco-friendly option. Cast iron is a recyclable material, and modern production techniques often emphasize reducing waste and energy consumption. By choosing cast iron, homeowners contribute to environmental conservation efforts while enjoying the benefits of a long-lasting product.

Furthermore, you can consider contacting architectural salvage stores that specialize in recycling old building materials. These stores often look for unique or antique wrought iron pieces to offer to their customers​​.
