Hot-rolled sheet, also known as hot-rolled sheet or hot-rolled steel plate, refers to an aluminum sheet product processed by a hot rolling mill. Usually, hot-rolled aluminum sheets are made from 4 x 8 aluminum sheet with a thickness of 400-500 mm that are processed multiple times by a hot-rolling mill. Due to the higher pressure during processing, the internal structure is more uniform and the grain size is better. The microstructure of the hot-rolled aluminum sheet is more uniform and dense. After anodizing, the surface texture of the hot-rolled aluminum plate is consistent, without ripples and color difference.
In the process of hot-rolled sheet processing, it is necessary to reasonably control the metallographic structure, mechanical properties, surface quality and geometric size and shape of the hot-rolled aluminum sheet to meet the quality requirements of subsequent processing and final products. In the hot rolling process of aluminum and aluminum alloys, the change of microstructure is a very complicated process. First, the grains of the material are deformed under the action of the strong rolling force, the as-cast grains are flattened, and the grains of the material are flattened along the rolling direction, while being elongated and strain hardened, and then dynamic recovery and dynamic regeneration may occur. crystallization.
Hot-rolled sheet products are generally divided into two categories, one is hot-rolled thick aluminum plate, and the other is hot-rolled aluminum coil. Hot-rolled thick aluminum plate refers to an aluminum alloy plate with a thickness of not less than 6.0 mm. The main varieties are hot-rolled plate (H112), annealed plate (O), quenched or quenched pre-stretched plate, etc. Hot rolled 1/8 aluminum sheet are usually used in hot rolling mills. It is produced by the block method, and its typical process is: ingot (homogenization) milling, edge rolling, heating, hot rolling, shearing, interruption, straightening.

I recently worked on a project that required some unique materials, and I ended up using expanded stainless steel sheets with a PVD coating. I thought I'd share my experience in case anyone is considering similar materials for their own designs. So, first off, expanded stainless steel is pretty interesting. It’s made by taking a flat sheet of stainless steel and using specialized equipment to cut and stretch it, which creates a mesh-like structure with raised holes and connecting webs. The result is a strong, yet lightweight material with a lot of texture and flexibility. What I didn’t realize at first is just how versatile it can be, both functionally and aesthetically. The best part about expanded metal sheets is how easy they are to work with. Whether you need to cut them, shape them, or install them, the material is very adaptable, which made it perfect for my needs. I used these sheets for a few different elements in my project—specifically for decorative partitions, wall panels, and even a ceiling installation. The geometric patterns and textures that the sheets provide give a modern, stylish look that’s both functional and visually appealing. Now, as for the PVD coating—this is where things really got interesting. PVD (Physical Vapor Deposition) is a process that applies a thin layer of metal to the surface of the material, giving it a unique, durable finish. The coating adds both visual appeal and protection to the metal. I chose a specific PVD coating that gives the expanded sheets a sleek, high-end finish. It also makes them resistant to scratches and wear, which is important for the long-term durability of the project. One of the main reasons I opted for expanded stainless steel with PVD coating was the combination of durability, aesthetic flexibility, and functional benefits. The open structure of the metal allows for excellent air, light, and sound circulation, making it perfect for spaces where ventilation or visibility is important. I was able to use it for some protective screens and exterior facades, where both aesthetic appeal and practical performance were essential. Overall, the material worked out really well for my project. It brought the modern, industrial vibe I was aiming for while still being practical and easy to install. If you're thinking about using expanded metal sheets, I’d definitely recommend exploring PVD coatings as they can really elevate the design. I got my sheets from InoxMetalArt, who helped me select the right finish and provided the materials exactly as I needed. The experience was smooth, and the quality of the materials was great, so I was very pleased with how everything turned out.
