As a one-stop-shop<\/strong>, LEFFER covers the complete fabrication process chain – from product development, engineering, and prefabrication to assembly, welding, testing, coating, and transport management. Every step is executed in-house, ensuring precision, reliability, and the highest quality standards for critical industrial applications.<\/p>\n\n\n\n

Material Expertise is a core strength, i.e. carbon and low-alloy steels, high-strength quenched & tempered steels, wear-resistant steels, corrosion-resistant and nickel-based alloys, duplex and superduplex steels, austenitic steels, and titanium.<\/p>\n\n\n\n

Our name stands for robustness and durability: whether it\u2019s a pressure vessel, heat exchanger, gasholder, machinery, or complete plant module, every product is engineered to perform flawlessly on site. With decades of experience and skilled teams, we handle complex, large-scale, and cross-functional projects, including modules, skids, and complete plant assemblies.<\/p>\n\n\n\n

Cutting & Sawing<\/h2>\n <\/div>\n \n
\n \n\n

Precise cutting is the first step in any manufacturing process. Using gantry cutting systems, tube cutting machines, and automated sawing and drilling lines, we process sheet metal, tubes, and profiles made of all standard materials \u2014 from carbon steel to titanium. The highest level of precision forms the foundation for all following manufacturing steps.<\/p>\n\n <\/div>\n \n \n <\/div>\n\n\n\n

Forming<\/h2>\n <\/div>\n \n
\n \n\n

Whether bending, rolling, or press-folding\u2014we process sheet metal up to 100 mm thick. Press-folding robots and state-of-the-art rolling mills enable us to produce complex geometric shapes with extremely tight tolerances, as required for pressure vessels, pipe bends, and plant components.<\/p>\n\n <\/div>\n \n \n <\/div>\n\n\n\n

Machining<\/h2>\n <\/div>\n \n
\n \n\n

Using our fully equipped CNC machining centers, we perform deep-hole drilling, milling, turning, boring, and face milling for components of various sizes and levels of complexity. This results in high-precision components that meet even the most stringent international design codes and standards.<\/p>\n\n <\/div>\n \n \n <\/div>\n\n\n\n
