ASTM A792M Slitting Steel Coils GI Galvanized Sheet G90 0.75mm

ASTM A792M GI Galvanized G90 0.75mm Strips & Slitting Steel Coils for Light Steel Keel Frame

There are three main parts to a slitter: the uncoiler, slitter arbors/rotary knives, and a recoiler.

Uncoiler: The master coil is loaded onto the uncoiler at the entry of the machine. Then the uncoiler uses an expandable mandrel to grip the master coil on its inside diameter. The coil rotates off the mandrel, and the head of the coil is threaded into the machine’s edge guides.

Slitter: The material is fed length-wise into the slitter head, which consists of two parallel arbors. These parallel arbors are mounted with a customized set of rotary slitting knives and rubber stripper rings. Rubber rings help pull the material through the slitter arbors, while the knives penetrate the steel causing the material to break or fracture.

The key to running an efficient precision coil slitting job is in the setup. Alliance Steel uses precision tooling and knives to ensure the best slit edges and a computer-automated system to assure spacing and horizontal knife clearances.

Rule of thumb: the harder the material, the less the slitting knives must penetrate. The softer the material, the deeper the knives need to go before the material slits/breaks.

Recoiler: The recoiler’s primary purpose is to wrap the slit coils back into a coil form for packaging and shipment.

Slit coils are produced by a process called coil slitting. This uses a coil splitter that cuts a main coil of metal into several narrower coils as it passes through a set of slitting blades. The continuous process is very precise and one of the best methods for cutting metal.

Our range includes galvanised coils, galvanised sheets and galvanised slit strip rolls.

We offer first class material with MTC (Mill Test Certificate).
