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.

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.

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 today's world, energy efficiency is a crucial consideration for both homeowners and builders. Aluminum window frame extrusions can be designed with thermal breaks—insulating materials that reduce heat transfer. This feature significantly enhances a building's energy performance by minimizing heat loss in winter and heat gain in summer. By using energy-efficient aluminum frames, homeowners can lower their heating and cooling costs, thus leading to a more sustainable and economical living environment.

Slimline aluminium profiles are thin, lightweight yet robust structural components made from aluminum. They are designed to serve various functions, such as framing systems for doors, windows, and partitions, as well as support structures in furniture design and display systems. These profiles are characterized by their sleek design, often incorporating clean lines and contemporary finishes, making them ideal for modern architectural projects.

1. Nylon Wheels These are the most common type of wheels used for sliding doors. Nylon is lightweight, resistant to corrosion, and produces minimal noise during operation. Nylon wheels are ideal for interior doors, as they glide smoothly and require minimal maintenance. However, they may wear down faster than other materials when exposed to outdoor conditions.
