Description
Hot-Dip Al-Si Coated Welded Steel Tube
Manufactured via hot-dip aluminizing with an Al-Si alloy coating, MESCO's aluminized silicon steel pipes deliver exceptional high-temperature oxidation resistance and long-term corrosion protection. With 3,000 MT in stock and exclusive coverage of three coating weights, we are your most reliable supply partner for demanding thermal applications.
From raw material to finished product, MESCO upholds rigorous process standards and maintains ample ready stock to give your project every competitive edge. All three coating weight grades are held in ready inventory — making MESCO one of the rare suppliers capable of delivering the complete Al-Si pipe range without lead time.
Coating weight directly determines corrosion service life and thermal endurance. The 120 g/m² grade suits cost-sensitive, moderate-temperature applications; 240 g/m² is the widely adopted industry benchmark with well-rounded performance; 300 g/m² is engineered for the most demanding high-temperature or aggressive-corrosion environments.
MESCO holds all three grades in ready stock, with no mandatory minimum order quantity (subject to available inventory). Mixed-grade orders are fully supported to satisfy diverse project requirements.
Parameters below are based on MESCO product test data. Final technical specifications shall be subject to the product standard confirmed by both parties. Combining high-temperature endurance, corrosion protection, and excellent formability, aluminized silicon steel pipes serve a wide range of demanding industries.
