In terms of fire safety, FRP ducts have a superior rating due to their inherent flame retardancy. They do not support combustion and produce minimal smoke, ensuring safety in case of a fire emergency They do not support combustion and produce minimal smoke, ensuring safety in case of a fire emergency
Door: flat door, sliding door and folding door
1. Flat door has good airtightness and can effectively prevent wind, sand, dust, or other impurities from entering the house; security, aluminum alloy material, is very convenient and safe to use.
2. Sliding door has simple operation and smooth sliding; it is convenient to divide and effectively use the space of the house; it has a good sound insulation effect; it is conducive to the light and transparency of the overall indoor space.
3. Folding door
After the folding door is opened, it can be moved to the side. The room is more transparent and will appear broader. It has the functions of heat preservation and heat insulation, moisture-proof, fire-proof and flame-retardant, noise reduction and sound insulation.
Packing:
Extruded profile may be passed into a cooling bath as it comes out depending on the type of alloy. Cooling is a critical step since it retains adequate metallurgical properties in the metal.
There are differences in their chemical composition, but the primary difference between cast iron and wrought iron is in how they’re produced: cast iron is iron that’s been melted, poured into a mold (i.e. a “cast”), and allowed to solidify into its current shape. Wrought iron, on the other hand, is iron that’s been heated and hammered with tools (i.e. “wrought,” the archaic past tense of “work”) to form it into a precise shape.
6061 grade exhibits somewhat low strength compared to other grades in the 6000 series. Moreover, it has wide-ranging mechanical properties giving it incredible forming capabilities.


These profiles are commonly used in the furnishing and building sectors for the assembly of doors and windows as their main purpose is to house and secure glass panels within door and window frames.


In an age where technology dominates, the historical significance of cast iron spears serves as a reminder of the ingenuity of our ancestors. They not only revolutionized warfare but also laid the foundation for advancements in material usage and production techniques. As we reflect on the past, we recognize that the cast iron spear is more than just a weapon; it is a testament to human creativity, resilience, and the timeless struggle for survival.
One of the most striking aspects of real spears is their diversity. Across different regions and eras, spears have been designed for specific purposes, illustrating how intimately human societies were connected to their environments. In Africa, for instance, the Assegai—a type of spear used by the Zulu people—was known for its long, slender design that allowed for precision in hunting and combat. Meanwhile, the Roman pilum was engineered to be a throwing spear, featuring a unique design that disrupted enemy shields, demonstrating the tactical thinking of ancient Roman armies.
You must also consider the material thickness of the specific aluminum profiles you are purchasing.
Wrought iron is known for its durability and potential for reuse or recycling. This makes it a valuable material even at the end of its life. Before disposing of the material, assessing its condition is crucial to determining the most appropriate disposal method:

The aesthetic appeal of ornamental wrought iron is also highly adaptable, seamlessly fitting into various design themes. It can blend effortlessly with rustic, industrial, or classical interiors, making it a versatile choice for homeowners and designers alike. The ability to paint or finish wrought iron in various colors further enhances its adaptability, allowing it to complement different decor styles.
Some circumstances, depending on the size and complexity of the profile, make it difficult to improve the tolerance as outlined in BS EN 755.
