Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, specializing in high-quality metal perforated solutions. Our Stainless Steel Spiral Punched Tube with 2mm pitch, 3mm hole diameter, and 12mm outer diameter is engineered for precision filtration, fluid distribution, and structural applications. This product combines the durability of stainless steel with a unique spiral design, offering consistent flow and mechanical strength. Whether you need it for chemical processing, water treatment, or automotive components, our tube delivers reliable performance backed by decades of manufacturing expertise.
The 2mm pitch ensures uniform spacing between holes, while the 3mm hole diameter provides an optimal balance between open area and structural integrity. The 12mm outer diameter makes it suitable for compact assemblies and narrow pipelines. Each tube is meticulously punched and formed into a spiral shape, enhancing its rigidity and allowing for easy integration into custom systems. Our factory uses advanced CNC punching machines to maintain tight tolerances, ensuring every hole is precisely aligned and burr-free.
