Heat, Corrosion, and Cost – The Triple Threat. CNB’s DX53D+AS Aluminized Tube Is the Solution Your Project Needs

Exhaust systems running too hot. Industrial ovens degrading internal components. Outdoor pipelines rusting under harsh weather. If any of this sounds familiar, it’s time to switch to CNB’s aluminized silicon steel tube.

Our DX53D+AS120 aluminized tube features a 90% aluminum – 10% silicon alloy coating that delivers exceptional performance where ordinary galvanized pipes fail. Here is why serious engineers choose CNB:

🔥 Heat Resistance Up to 550°C – While standard zinc-coated pipes begin to oxidize and discolor above 300°C, our AS-coated tube maintains structural integrity and a bright appearance even at extreme temperatures. Perfect for automotive exhaust systems, industrial heaters, barbecue grills, and heat exchanger coils.

🛡️ Corrosion Resistance That Lasts – The aluminum-silicon coating forms a dense Al₂O₃ oxide layer that seals the steel substrate from moisture and chemicals. In salt spray tests, aluminized steel dramatically outperforms standard galvanized products, making it ideal for marine environments and chemical plants.

💰 Superior Value Over Stainless Steel – For applications requiring both heat resistance and corrosion protection, aluminized tube offers a cost-effective alternative to expensive stainless steel grades, without sacrificing performance.

We produce aluminized tubes in diameters from 9mm to 219mm, thicknesses from 0.5mm to 5.0mm, and lengths up to 12,000mm. Round, square, rectangular, and custom sections are all available. Each tube undergoes 100% pressure testing (8kg for 15 seconds) before leaving our workshop.
