In addition to their durability, bend roof sheets are also highly resistant to weather elements. The metal surface of these sheets is designed to shed water, preventing accumulation that can lead to leaks and structural damage. Furthermore, many bend roof sheets come with protective coatings that enhance their resistance to rust and corrosion, further extending their lifespan. This makes them particularly suitable for regions that experience heavy rainfall or harsh winters.

Modern factories leverage advanced technologies such as automation and robotics. These innovations not only improve efficiency but also enhance product quality and reduce waste. By utilizing Computer Numerical Control (CNC) machines, factories can maintain consistent dimensions and design specifications, catering to the specific needs of clients. Furthermore, automated processes can significantly minimize human error, leading to less material waste and higher productivity.

The conventional surface treatment methods of titanium alloy include glow discharge plasma deposition, oxygen ion implantation, hydrogen peroxide treatment, thermal oxidation, sol-gel method, anodic oxidation, microarc oxidation, laser alloying, and pulsed laser deposition. These methods have different characteristics and are applied in different fields. Glow discharge plasma deposition can get a clean surface, and the thickness of the oxide film obtained is 2 nm to 150 nm [2–8]. The oxide film obtained from oxygen ion implantation is thicker, about several microns [9–14]. Hydrogen peroxide treatment of titanium alloy surface is a process of chemical dissolution and oxidation [15, 16]. The dense part of the oxide film is less than 5 nm [17–21]. The oxide film generated from the thermal oxidation method has a porous structure, and its thickness is commonly about 10-20 μm [22–25]. The oxide film from the sol-gel method is rich in Ti-OH, a composition that could induce apatite nucleation and improve the combining of implants and bone. It has a thickness of less than 10 μm [26–28]. Applied with the anodic oxidation method, the surface can generate a porous oxide film of 10 μm to 20 μm thickness [29–31]. Similarly, the oxide film generated from the microarc oxidation method is also porous and has a thickness of 10 μm to 20 μm [32, 33].
