The main difference between Hot - Rolled and Cold Rolled steel is how they are processed. Hot - Rolled steel is rolled at a very high temperature, typically over 1700 ° F, while cold-rolled steel is essentially hot-rolled steel further processed in cold reduction mills. Even beyond their processing temperature differences, there are numerous key differences between Hot - Rolled Steel and Cold- Rolled Steel.

What is Coil Slitting? Coil Slitting is the process of taking a wider master coil and slitting (cutting) it into a series of narrower coils by running the material through a set of rotary slitting knives. Each smaller coil is called a mult. Mults can be customized to your specific width and/or weight and packaged accordingly. What Materials Can I Slit? Alliance Steel can slit coils with material…

Metal has memory.  Learn more about equalizing the internal trapped stresses and how stretcher leveling can benefit your business.  What is Stretcher Leveling? Stretcher Leveling is a process that stretches steel beyond its yield point to eliminate internal stress. This process ensures that material stays flat even after fabrication like welding, laser cutting, shearing, forming, notching, and punching.  What…

Are you looking for sheets and blanks that are cut to the exacting thickness and dimensional consistencies? Keep reading to learn more about the multi–blanking and cut-to-length process and how it can benefit your business. What is Multi Blanking? Multi-blanking is a master coil process that combines slit to width and the cut to length process into a single operation. This process uses slitting heads…

What is Stretcher Leveling? Stretcher Leveling is the process of removing or breaking the memory of the coil to create “dead flat” or “laser flat” material. The primary function of this line is to transition a master coil to “laser flat” sheets. The first step is to flatten and reduce the crossbow. A crossbow is a curvature in the transverse (horizontal) direction. There are three E- Drive Levelers…

What is Galvanized Steel? Galvanized steel is coated with zinc to help prevent corrosion. Zinc forms a barrier, defending the metal itself from rust and other forms of corrosion. In addition, zinc reacts with oxygen when exposed to the atmosphere, thus forming zinc oxide. Furthermore, the zinc oxide reacts with carbon dioxide to firm a zinc carbonate. This stops further corrosion in most circumstances,…
