Hot or Cold Rolled? The Differences Between Steel Types

May 31st, 2018 by Natalie Mueller

Filed under: Industry News

It should come as no surprise that we here at Skolnik take great care in the steel we use to make our barrels. In every size we offer, from 15 gallon drums to 110 gallon and everything in between, we carefully consider every decision of the process, and one of the first to make is whether to use hot rolled steel, or cold rolled. Despite sounding like coffee orders, these terms describe how the steel is handled early on, and has a big impact on the final outcome of our barrels.

Regardless of the type of rolling process the steel ultimately goes through, when it’s first created it’s shaped into an ingot, billet, bloom or slab; the different shapes and sizes of the still raw, semi-finished steel. From there, the steel is heated above 1700 degrees Fahrenheit, which breaks down the crystals that make up the metal’s natural state. From there, the malleable molten metal is pushed through a variety of wheels, or rollers, that form the metal into its next shape. This can be the “I” shape of a structural beam, the round shape of a rod, or the flat sheets that we eventually use in our drums.

If this is all the work done on the steel, it’s considered hot-rolled. The steel is left to cool and then shipped off to be used in a wide variety of applications. Because of this shorter production time, hot-rolled steel is cheaper than cold-rolled. The trade-off is that is has an unattractive scale on the outside from being heated and is less accurate in its dimensions due to the shrinking and warping that occurs as it cools. Cold-rolled steel, on the other hand, isn’t finished after its initial shaping, and the additional steps it goes through are what sets it apart from its hot-rolled counterpart.

Once it’s been cooled to room temperature, there are a variety of finishing steps that cold-rolled steel can go through in this cooler state, including additional passes through rollers to further shape it, annealing, tempering and surface grinding and polishing. By going through these extra steps, cold-rolled steel is a cleaner, more attractive, more resilient metal with more accurate dimensions than steel that has merely been hot-rolled.

Here at Skolnik we only use cold-rolled steel in our products. In order to insure the correct dimensions crucial for maintaining the quality and consistency of such products as our 15 gallon drums, cold-rolled steel is the appropriate choice. Not only that, but it’s also better at taking paints and finishes that we apply to our barrels, making sure the surfaces of each drum are up to our demanding standards. Of course, how the steel is rolled is only one of many decisions made on the path to an excellent barrel, but by making the right choices early on, we insure that we make the absolute best product for our customers.

Deciphering the Code: 1A2 Drums

Filed under: DOT/UN, Stainless Steel

The title of this post isn’t meant to be a super-secret code; it’s meant to denote a UN certified drum of a specific material. Most simply put, a 1A2 drum is a UN certified open head steel drum. The coding helps anyone coming into contact with the drum to understand key characteristics of the container and it’s intended, safe uses, and proper shipping and storage procedures.

So what goes into these codes? Well, the ‘1’ indicates that this container is a drum. Of course, if you saw the drum, you’d recognize that it is a drum, but on paper, such as shipping and storage manifestos, the container classification is pertinent to proper operations and organization. The ‘A’ informs the reader that this container is made of steel. The material of a container speaks volumes to how it should be used, filled and any safety requirements. Finally, the ‘2’ tells the reader that this steel drum has an open head, meaning the lid of the drum is detachable and can be removed.

With this knowledge, anyone can decipher the UN coding: this container is an open head steel drum. And should be used as such.

Open head? That means this drum has a removable lid secured to the drum with a bolt ring or a lever lock to prevent the container from opening in transit.

Steel? Fantastic. Steel drums are often used for the containment of chemicals, pharmaceuticals and food for storage or transport. Stainless steel is a compatible material for the containment of a wide variety of different products and items, but we still recommend discussing your needs with a Skolnik representative before choosing a specific type of drum.

Now that you can read the code, call Skolnik to learn more about our products and what type of container is the best fit for your needs.
