As mentioned previously, prime CRFH is not a large product group. It is typically used in applications where limited bending or forming is needed. It is often used in the construction and packaging industries but requires very specific specifications as it is part of the structural integrity of the end product.

The steel can be processed further to become a CR-based coated product (with an additional coating stage) or a finished CR product after annealing and finishing.

Steel processing begins in the mill by rolling a hot rolled slab to hot rolled coil, followed by a pickle bath to remove the scale and imperfections. Once pickled, the steel is sold as hot rolled pickled dry (HRPD), hot rolled pickled and oiled (HRPO), or it is pushed further to become hot rolled-based coated products.

Cold rolled full hard (CRFH) steel is a product that has not been fully finished in a cold reduction mill. The full hard designation indicates that the steel has not been annealed, meaning it is more rigid and less malleable than other types of steel. This makes it ideal for applications with high levels of strength and durability.

At Mainline Metals, we specialize in guiding our customers on available products to meet their applications while advocating for their economic, qualitative, or volume-based needs.

Cold rolled full hard can also be a downgraded application for an alternative product. Non-prime CRFH can be flagged during the production process for various qualitative reasons. However, it’s important to note that secondary/excess CRFH doesn’t always stem from issues with prime CRFH.

There are literally dozens of ways of clamping the work, using a variety of strategies depending on the type of work and the cut you are trying to perform.

Cold rolled full hard is not a familiar product line to most, and given its specific requirements due to its non-standardized production, it requires a partner with experience and support to best apply it.

Processing the steel in a cold reduction mill to reduce its gauge/thickness makes the steel thinner. Once reduced, the coil is officially CRFH. This product can be sold as is. However, as a prime product, it accounts for a very small segment within the overall mill portfolio.
