Cold Formed Sheet Piles Vs. Hot Rolled Sheet Piles
For people who work in construction, the debate of which the better sheet pile is has been going on for awhile. If you’re a traditional builder who prefers reliability and history in his work, then you might favor rolled sheet piles. If you’re new or more adventurous with your choices, then you prefer the cold form sheet. Sheet piling companies know the difference between these two products.
Sheet Piling Companies Explain Cold Formed Vs. Hot Rolled Sheet Piles
What’s a hot rolled sheet pile?
Hot rolled sheet piles have been used for over a century. Over that time, they were used to build many heavy structures and have undergone many changes. When it first started, the sheets were flat. Eventually, they became U-shaped, then transitioned to the Z shape that it has now.
To better understand what hot rolling is, here’s the two step process that’s usually followed:
- Heat a pre-rolled steel beam blanks at a high temperature, so they’re easy to shape into sheet pile.
- Now, you can roll them to the specifications you want.
What’s a cold formed sheet pile?
This development in making sheet pile is much more recent. It was only introduced and used in the last 45 years. That’s why there are companies which are still not using this technique.
To make sheet pile through this method, you need to:
- Manufacture hot-rolled steel coil.
- Run it through a mill to form the coil into the sections of the sheet pile.
People who use this method would argue that this is more cost-effective and time-efficient, but it would really depend on your manufacturing process.
The real difference between the two is in the interlock. The hot rolled sheet pile vary from one manufacturer to the next. If you are to use different ones, you will need to make a transition piece. This would not be a problem though if you’re using the same manufacturer for the whole project.
On the other hand, cold formed sheet piles have similar sizes, so they will interlock — much like a hook and grip — regardless of which company manufactures them.
Although hot rolled sheet piles have to be from the same manufacturer to interlock, they are deemed to be more durable and better for hard driving. The tight interlocks are made form tough conditions, so it will be able to endure. To compare, cold formed sheet piles are cheaper to make, more flexible to use and easier to source. They also give you more choices in how you want to position these sheets.
