Aluminized Steel Sheet
Aluminized steel sheets have been hot-dip coated on both sides with aluminum-silicon alloy, creating a coating class (T1-13 to T1-60) that protects the substrate from high-temperature oxidation and corrosion.
Grade Cross-Reference Table
ASTM A463 Grade (ksi) | JIS G3314 Class (Coating Quality) | EN 10346 Equivalent (Base Grade +AS) |
33 | SA 1C (Commercial Quality, CQ) | DX51D+AS (CQ) |
37 | SA 1A (Drawing Quality 1, DQ1) | DX52D+AS (DQ1) |
40 | SA 1D (Drawing Quality 2, DQ2) | DX53D+AS (DQ2) |

Applications
Aluminized steel sheets excel in high-temperature and corrosive environments such as:
Automotive exhaust systems (mufflers, catalytic converter shields)
Furnace and oven linings (heat-reflective panels)
Decorative façades and architectural cladding (heat-resistant, corrosion-resistant)
Heat exchangers and industrial ducts (long service life at elevated temperatures)
