Our Cut-to-Length (CTL) service delivers precision-flat, custom-sized steel sheets tailored to your exact project specifications. Using advanced straightening, leveling, and shearing technology, we convert hot-rolled, cold-rolled, and galvanized coils into sheets with exceptional dimensional accuracy and surface quality.
Whether you need standard industry sizes or fully customised sheet dimensions, our CTL line ensures consistent flatness, tight tolerances, and defect-free edges, making it ideal for fabrication, laser cutting, bending, and general engineering applications.
Our slitting lines produce precision-slit coils tailored to your exact width requirements, ensuring optimal performance in downstream manufacturing. Using high-accuracy rotary knives and tension-controlled recoiling systems, we convert HR, CR, HRPO, and galvanized coils into clean-edged, uniform-width slit strips with exceptional consistency.
Whether you require narrow-width strips for tubing, stamping, roll forming, or specialised fabrication, our slitting capability delivers tight tolerances, burr-free edges, and superior coil build quality.
Our customised slit coils ensure precision, stability, and efficiency—helping your production lines run faster, smoother, and with minimal downtime.
High-performance steel solutions for structural and industrial applications
Our Electric Resistance Welded (ERW) Pipes and Tubes are produced exclusively from premium hot-rolled steel coils, ensuring superior weld integrity, precise dimensional accuracy, and consistent mechanical performance.
At TOO METALLOPROKAT KARAGANDA (KAZMET) engineered to support demanding structural, mechanical, and fabrication requirements, our ERW range delivers an optimal balance of strength, reliability, and cost efficiency.
Production begins with select hot-rolled coils, slit to exact strip widths and fed into a continuous forming line. Through a controlled roll-forming process, the strip is shaped into round, square, or rectangular profiles. The longitudinal edges are fused using high-frequency electric resistance welding (HF-ERW), forming a clean, uniform weld seam without filler metals.
Post-welding, the pipes undergo a series of precision processes—sizing, straightening, non-destructive testing, and accurate cut-to-length finishing—ensuring each product meets stringent quality standards for alignment, thickness, and surface finish.
