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).
Our Services
1) Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted
Galvanizeed Steel Sheet.
2) High heat resistance: The reflective surface of the material aids in efficiently reflecting the
sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity
converts into energy savings.
3) Aesthetics: PrePainted Galvanized steel sheet is available in plethora of patterns
and multiple sizes as per as requirements that given by our customers.
4) Versatility: can be used in the various areas.

| Description |
Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel. Galvanized steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion. |
