1) Corrosion Protection Needs & Market Drivers

In Russia, transmission towers, guardrails and various steel structures operate under extremely cold and humid conditions, requiring very long corrosion protection life. Hot-dip galvanizing is a key process for improving the durability of such components, and the gas hot dip galvanizing furnace is the heart of the entire galvanizing line. Furnace chamber size, gas utilization and zinc bath temperature uniformity all directly affect production cost and coating quality.

2) Customer Project Background & Pain Points

The customer is a manufacturer of steel structures and protective elements, many of which are used in outdoor projects. Their older gas hot dip galvanizing furnace had a relatively small chamber and could not handle larger structures effectively. Gas utilization was also low, leading to higher operating costs. With increasing order volumes, the customer needed a gas hot dip galvanizing furnace with a larger effective size and better energy efficiency.

3) Furnace Configuration & Key Features

Wuxi Wondery Industry Equipment supplied a gas hot dip galvanizing furnace with an effective size of 4.0×1.2×2.7 m:

• Effective dimensions: 4.0×1.2×2.7 m, suitable for overall galvanizing of medium and large steel structures;

• Heating: gas-fired, with high-efficiency burners and optimized flue design;

• Control system: temperature monitoring plus combustion safety interlocks for safe, continuous operation.

The gas hot dip galvanizing furnace uses an optimized zinc bath design to improve circulation and temperature uniformity, reducing uneven coatings caused by local hot or cold spots.

4) Operating Experience & Customer Feedback

After upgrading, the customer can galvanize larger and more complex structures in a single dip, reducing segmented galvanizing and rework. The 4.0×1.2×2.7 m effective chamber covers the main product size range, making line scheduling smoother.
The customer reported that the gas hot dip galvanizing furnace from Wuxi Wondery achieves a good balance between zinc bath temperature control and gas consumption. Coating thickness and appearance are more consistent, and on-site inspection pass rates have improved. During long continuous runs, furnace temperature fluctuations are small, reducing line stoppages caused by temperature deviations.

5) Value for Target Users

For Russia and other regions with severe corrosion environments, upgrading the gas hot dip galvanizing furnace is a key lever to extend steel structure service life and enhance competitiveness. The 4.0×1.2×2.7 m gas hot dip galvanizing furnace solution from Wuxi Wondery Industry Equipment provides a stable core equipment foundation for overall galvanizing of medium and large steel structures.
