Steel Plate for Better Quality Looking for trusted galvanized steel plate manufacturers in China? You've come to the right place. As a direct factory with 20 years of structural steel experience, GNEE Steel supplies EN 10346 compliant sheets at factory prices. Recently, we have successfully optimized the production process of our S350GD+Z160 galvanized steel plate, resulting in improved product quality, more stable performance, and higher customer satisfaction.
The production process of galvanized steel plates is complex, involving multiple stages such as raw material preparation, hot rolling, cold rolling, galvanizing, and post-treatment. Any deviation in these stages can affect the quality of the final product. Recognizing the importance of process optimization, GNEE Steel invested heavily in research and development to upgrade its production lines, focusing on improving the galvanizing process, enhancing quality control measures, and optimizing post-treatment procedures for the S350GD+Z160 galvanized steel plate.
Galvanized steel plate
Enhanced Galvanizing Process for Uniform Zinc Coating
The galvanizing process is crucial for the corrosion resistance of the S350GD+Z160 galvanized steel plate. GNEE Steel has upgraded its hot-dip galvanizing equipment and optimized the process parameters to ensure a more uniform and consistent zinc coating.
One of the key improvements is the installation of a new zinc bath circulation system, which ensures that the zinc liquid in the bath is evenly mixed, eliminating temperature differences and concentration gradients. This results in a more uniform zinc coating thickness across the entire surface of the steel plate, with a tolerance of less than ±5% of the target coating weight (160g/m²).
In addition, GNEE Steel has optimized the immersion time and speed of the steel plate in the zinc bath. By precisely controlling these parameters, we can ensure that the zinc coating adheres firmly to the steel surface, reducing the risk of coating peeling or blistering.

Strengthened Quality Control Measures
To ensure the consistency and reliability of the S350GD+Z160 galvanized steel plate, GNEE Steel has strengthened its quality control measures throughout the production process. We have implemented a comprehensive quality management system that includes online monitoring, sampling inspection, and final testing.
Online monitoring systems have been installed at key stages of the production line, such as the cold rolling mill and the galvanizing line. These systems continuously monitor parameters such as thickness, width, temperature, and coating weight, providing real-time data to operators. Any deviations from the set standards trigger an alarm, allowing operators to take immediate corrective actions.
In addition to online monitoring, GNEE Steel has increased the frequency of sampling inspection. For the S350GD+Z160 galvanized steel plate, samples are taken every 30 minutes during production for detailed testing, including chemical composition analysis, mechanical property testing, and coating quality inspection.
The final testing stage is even more rigorous. Each batch of the S350GD+Z160 galvanized steel plate undergoes a series of tests, including:
Chemical composition analysis: Ensures that the steel meets the required chemical composition standards, which is essential for its mechanical properties and galvanizability.
- Mechanical property testing: Includes tensile strength, yield strength, elongation, and impact toughness tests to verify that the product meets the mechanical performance requirements of EN 10346.
- Coating quality inspection: Checks the coating thickness, adhesion, and appearance to ensure that the zinc coating provides effective corrosion protection.
- Dimensional accuracy measurement: Verifies the thickness, width, and length of the steel plate to ensure it meets the customer's specifications.
These strict quality control measures ensure that every piece of the S350GD+Z160 galvanized steel plate leaving the factory meets the highest quality standards.
The optimized production process of the S350GD+Z160 galvanized steel plate by GNEE Steel has resulted in significant improvements in product quality, performance, and customer satisfaction. By enhancing the galvanizing process, strengthening quality control measures, and optimizing post-treatment procedures, we have created a product that meets the highest standards of the industry.
