Audited Supplier Audited by an independent third-party inspection agency
Dx51D+AS240 is a hot-dip aluminized silicon steel coil with an ultra-heavy 240 g/m² coating (both sides). Composed of 90% aluminum and 10% silicon, it delivers unmatched corrosion resistance and thermal reflectivity for oil/gas insulation jackets, valves, and cryogenic piping in extreme environments.
Superior Thermal Management
95% infrared reflectivity at ≤500°C - slashes surface temperatures of insulation layers. Maintains integrity from -196°C to 550°C (vs. galvanized steel's 300°C limit).
Extreme Corrosion Resistance
3,000+ hours salt spray performance (7× longer than galvanized steel). Resists H2S, seawater, acids, and alkalis - validated against POSCO/Korean standards.
Exclusive High-Coating Supply
MESCO pioneered AS240/AS300 production - Asia's sole supplier of ≥240 g/m² coating. 5,000-ton daily stock for 3-day delivery (critical for project timelines).
Eco-Certified & Safe
ROHS/FDA/LFGB/REACH compliant - zero heavy metal leaching. Low-VOC welding fumes (protects workers in confined spaces).

Q1:What is the main difference between the aluminized silicon products of MESCO STEEL and similar products available on the market?
A:MESCO STEEL is the first domestic supplier to produce As240, and it is also the only supplier capable of producing As300 products. The advanced nature and scarcity of our technology ensure the excellent performance of the products.
Q2: How does MESCO ensure consistent quality control for raw materials?
A: As the source manufacturer, we implement stringent tolerance management from raw material procurement to production, guaranteeing dimensional accuracy and coating uniformity.
Q3: Do you stock standard-grade products for urgent orders?
A: Yes. We maintain ready inventories of common grades/specifications (e.g., DX51D+AS240 for exhaust systems), enabling 3-day delivery.
