The ultimate in coil processing
Protube Engineering offers a complete range of slitting and cut-to-length solutions for processing a wide variety of materials and thicknesses. We supply everything from knives, spacers and rubbers to leveller rolls, shear blades, spares and even complete lines with integrated packaging systems. Our systems are designed for steel (coated & uncoated), stainless, aluminium and specialty alloys, delivering efficient, accurate and reliable coil processing.
& Cutting
Slitting and Cut-to-length Lines
Leverage a robust coil-processing solution engineered for flexibility, precision, and productivity. Our slitting lines handle a diverse range of materials, from hot-rolled, cold-rolled, galvanised, pickled, or oiled steel, to stainless, aluminium, and light alloys, with thickness capacities spanning from ultra-thin 0.1mm up to a hefty 20mm.

Benefits
High Capacity – These systems are built for high-capacity output capable of producing dozens of sub-coils per main coil, and processing hundreds of thousands of tons annually through advanced automation that minimises downtime and staffing needs.
Cut-to-length Modules – Complementing the slitting functionality, the cut-to-length modules deliver precise, burr-free sheet lengths optimised for downstream fabrication. Configurable automation levels ensure swift line changes and continuous, high-quality operation.

& Machine Elements
TKM
TKM Rotary Slitter Knives epitomise precision and durability for demanding slitting applications in the metal industry. Engineered with ultra-tight thickness tolerances (as precise as ± 0.0005 mm), they ensure exceptional accuracy and repeatability. Available in four tolerance classes and featuring four surface finish options—from ground to mirror-polished, they deliver outstanding wear resistance and burr-free cutting on sheet metals ranging from 0.006mm up to 16mm (and in special cases even up to 40mm). Each knife is tailored with a finely tuned material and heat-treatment recipe to optimise toughness and longevity.
TKM rotary slitter knives deliver precise, clean cuts with exceptional wear resistance, ensuring maximum uptime and consistency in coil processing. Paired with our rubber stripper rings, which provide reliable strip control and protect material surfaces, they form a high-performance solution that improves efficiency, reduces scrap, and extends tooling life.
