Anti-Climb High Security Fence: This is a type of high security fence that is specifically designed to prevent climbing. It typically features a smooth surface or sharp edges that make it difficult for someone to gain a grip and climb over the fence.
Anti Climb 358 Security Fence: This is a type of anti-climb fence that is made with a specific mesh pattern known as 358. The pattern includes small openings that are too small for fingers to fit through, making it nearly impossible to climb. The number 358 refers to the measurements of the mesh pattern - 3 inches of horizontal space, 0.5 inches of vertical space, and a wire gauge of 8.
Curved 358 Welded Wire Mesh Fence: This is a variation of the 358 security fence that includes curved sections. The curves add an additional layer of security by making it even more difficult to climb over the fence. The fence is made by welding wire together in the 358 mesh pattern.
World's Largest 3D Printing Titanium Fighter Parts
On May 24, 2013, during the 16th China Beijing International Science and Technology Industry Expo, AVIC Heavy Machinery Holdings Ltd.’s laser subsidiary showcased a groundbreaking achievement: aircraft titanium alloy components that had won the 2012 National Technology Invention Award. These parts were developed using large-scale integral key component laser forming technology, marking a major milestone in advanced manufacturing.
Beihang University, in collaboration with AVIC Laser, played a crucial role in turning this innovation into an industrial reality. At the expo, the team also revealed for the first time large-scale titanium alloy parts used in fighter aircraft. This laser-based technology represents a significant leap forward from traditional 3D printing, offering a short-cycle, low-cost, and highly efficient digital manufacturing solution.
This breakthrough enabled the production of over 30 types of complex titanium alloy components, which have been directly manufactured and installed in various aircraft models, including large transport planes, carrier-based aircraft, the C919 passenger plane, and fighter jets. It not only addressed critical bottlenecks in aircraft development but also positioned China as the only country to master and apply laser direct manufacturing technology for high-performance large-scale metal parts.
Notably, the project achieved a world-first by overcoming challenges in laser forming processes, mechanical performance control, equipment integration, and technical standards for large titanium aircraft structures. Among the key achievements was the creation of four "glass-type" titanium alloy main bearing structural frames, which demonstrated exceptional strength and precision.
What's even more impressive is that Chinese researchers have managed to produce laser-shaped titanium alloy components that outperform those made in the U.S. This has solidified China’s position as the sole global leader in the production and implementation of large-sized laser-formed titanium alloy parts.
The laser titanium alloy forming technology has revolutionized the manufacturing process. By eliminating the need for expensive raw materials and custom molds, it reduces material waste by up to 90%. Traditional processing costs, which could be 1 to 2 times the material cost, are now reduced to just 10% with this method. For instance, producing 1 ton of complex titanium alloy structure using traditional methods might cost around 25 million yuan, while the laser 3D welding rapid prototyping approach brings the cost down to approximately 1.3 million yuan—just 5% of the original expense.
Additionally, 3D printing allows for the creation of complex titanium alloy structures in one piece, significantly reducing labor hours and enhancing material strength. For example, if the F-22’s titanium forgings were produced using China’s 3D printing technology, they could be up to 40% lighter while maintaining the same level of strength. This advancement opens new possibilities for aerospace engineering and sets a new standard in modern manufacturing.
