SPECIALIST PRESSWORK AND HOT FLANGING

Presswork and hot flanging are highly specialised techniques in heavy boilermaking, essential for the repair and rebuild of vintage steam boilers. The ability to manufacture replacement flanged components is critical to restoring a boiler to its original design and ensuring long-term structural integrity.
