Direct supply from state-of-the-art production lines, manufactured to international structural grades and optimized for high-temperature durability.
The Sultanate of Oman is pushing forward with massive industrialization plans through special economic zones in Duqm, Sohar, and Salalah under Oman Vision 2040. However, the coastal geography introduces severe atmospheric challenges. With extreme levels of airborne salinity, high UV indexes, and rapid temperature fluctuations (ranging from winter sea breezes to interior desert heat exceeding 50°C), traditional metals degrade rapidly.
Our 55% Aluminum-Zinc Galvalume (Aluzinc) steel sheets are engineered explicitly to address this. The chemical composition combines the barrier protection of aluminum with the sacrificial protection of zinc. This creates an impermeable alloy barrier that resists salt-spray degradation along the Batinah coastline and stands up to the extreme solar radiative index (SRI) required to lower structural heat loads in industrial zones.
Analyzing the differences between traditional Galvanized Iron (GI) and Galvalume (GL) for Gulf standard industrial applications.
| Feature / Specification | 55% Galvalume (Aluzinc) Sheet | Hot-Dipped Galvanized Sheet (GI) | Oman Project Relevance |
|---|---|---|---|
| Chemical Composition | 55% Al, 43.4% Zn, 1.6% Si | 99% Zinc coating layer | Aluminum barrier stops acid rain, Zinc protects edges. |
| Service Life (Coastal) | 25 - 40 Years | 10 - 15 Years | Crucial for infrastructure near Salalah (monsoon areas). |
| Thermal Reflectivity | > 70% (High SRI) | < 40% (Degrades over time) | Lowers roof temperature by up to 15°C under Gulf sun. |
| Typical Coating Mass | AZ50 to AZ150 (g/m²) | Z100 to Z275 (g/m²) | AZ150 recommended for heavy industrial applications. |
| Yield Strength Grades | G300 to G550 (Full Hard) | SGCC, DX51D, S250GD to S550GD | High strength G550 ideal for cyclone-resistant cladding. |

From modern warehouse installations to large-scale petrochemical developments, our materials provide structural peace of mind.
We supply high-yield G550 Galvalume coils suitable for standing seam roofing profiles. They protect logistic warehouses in Sohar Freezone from humidity and structural stress.
Given Oman's push for green hydrogen and solar energy plants in Ibri, our high-coating AZ150 structural steel provides up to 30 years of maintenance-free mounting foundations.
Engineered to withstand sulfur emissions and corrosive chemical run-offs, our Galvalume solutions are utilized in structural claddings for PDO oilfield facilities.
How we secure direct transit and ensure quality consistency from our Chinese facility to your job sites in Oman.
All exports to Oman must clear strict local customs requirements and conform to standard construction practices. We supply comprehensive testing documentation alongside our shipments, including:
Leveraging the strategic location of Ningbo Port, we arrange optimized shipping routes ensuring competitive transit times and secure container storage methods to prevent transit condensation:
Engineered steel products customized for commercial processing and industrial fabrication across the Sultanate of Oman.
Resolving key design and procurement inquiries regarding Galvalume installation in Gulf Cooperating Council (GCC) regions.
For coastal industrial zones like Sohar Port and Special Economic Zone at Duqm, we strongly recommend a minimum thickness of 0.5mm to 0.7mm to withstand physical structural loads and strong winds. The Al-Zn coating weight should be at least AZ150 (150 g/m² double-sided coating) to secure a design life exceeding 25 years under high maritime chloride concentration.
Unpainted Galvalume possesses a high Solar Reflective Index (SRI), reflecting approximately 70-75% of solar radiation compared to only 30-40% for typical unpainted galvanized sheets. Over years of thermal exposure, Galvalume does not lose reflectivity due to surface oxidation, minimizing internal building ambient temperatures and lowering structural HVAC loading significantly.
Yes. Ningbo Puppet Steel provides complete shipping packs including original legal Bill of Lading, Certificate of Origin (CO) endorsed by standard commerce chambers, detailed Mill Test Certificates (MTC) conforming to chemical/physical metrics of ASTM A792, and custom packaging lists ensuring direct release at Sohar Port, Port Qaboos, or Salalah.
