Custom-Built Industrial Painting Booth System for Large Transformer Tanks-Dated Sep 16,2026 

State-of-the-Art Coating Facility Designed to Handle 50-Ton, 9.8-Meter Transformer Tanks

[Jubail Industrial City, Saudi Arabia] — In a significant advancement for industrial coating capabilities in the region, a fully customized industrial painting booth system has been designed for the surface treatment of large transformer tanks. The project, undertaken for Nal Gulf General Contracting, a leading Saudi provider of industrial contracting and engineering services, represents a major milestone in heavy-equipment coating technology.

The painting booth is engineered to accommodate transformer tanks with maximum dimensions of approximately 9,800 mm in length, 2,800 mm in width, and 3,400 mm in height, with a maximum weight capacity of 50 tons. The system incorporates a heavy-duty rail transfer system for safe and efficient loading and unloading of the massive components.
