Stainless Steel Thin-Wall Pipes 0.5mm, JIS G3459, Lightweight, HVAC Ducting
Stainless Steel Thin-Wall Pipes (0.5mm Wall Thickness) by Jiangsu China Steel Union Industrial Co., Ltd are precision-engineered for lightweight, corrosion-resistant ducting in HVAC (Heating, Ventilation, and Air Conditioning) systems. Compliant with JIS G3459, these pipes combine ultra-thin walls (0.5mm) with high-strength SUS304/316L stainless steel, reducing weight by 40% compared to traditional ducts while maintaining structural integrity. Ideal for commercial buildings, hospitals, and industrial facilities, these pipes resist humidity, condensation, and chemical exposure, ensuring long-term performance in air handling units (AHUs), exhaust vents, and fresh air distribution networks. The seamless or longitudinally welded design minimizes airflow resistance and simplifies installation.
