Common surface treatment processes for aluminum doors and windows are electrophoretic coating, fluorocarbon spraying, wood grain transfer coating, anodizing, and electrostatic powder coating. In most cases, after good surface treatment, aluminum profiles have good atmospheric corrosion resistance. It is moisture-proof, sunscreen, flame proof, aging proof, high-temperature deformation proof, low-temperature embrittlement proof, durable and stable, and suitable for various climates.

door track rollers. The weight and size of the door will determine the type of rollers needed to support the door and ensure smooth operation. It is also important to choose rollers made from high-quality materials that can withstand frequent use and provide long-lasting durability.
The benefits of using cast iron for spears lie in its inherent properties. Cast iron, known for its excellent castability, is resilient and suitable for manufacturing sharp, sturdy spearheads that can withstand the rigors of battle. The material's high carbon content contributes to its hardness, allowing for effective penetration without easily blunting. Moreover, the casting process enables the creation of complex shapes that traditional methods cannot replicate, leading to innovative spear designs tailored for specific combat contexts.
