What is cold rolled steel?

Cold rolled steel is basically hot rolled steel that has had additional processing. The steel is processed further in cold reduction mills, where the material is cooled at room temperature. This is followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.

Often described as ‘lightweight’, cold rolled steel is 75% lighter than structural (hot rolled) steel, but is equal in strength, making it more economical to produce, transport and install. Because it is pliable, it is rolled into sheets, or other shapes. Stock bars and sheets of cold-rolled steel are regularly used in areas of manufacturing.

As such, cold rolled steel is a great material to use for steel sheds, industrial buildings, commercial buildings, garages, hangars and so on.

Why choose Cold Rolled Steel?

Cost effective

Cold rolled steel is the most economical portal building system available.

Speed of construction

The elements of your steel building arrive on site ready for assembly. No on-site measuring or cutting is normally required and the main structure of the building can usually be erected within hours.

Ease of assembly

Assembly is normally simple. Due to the lightweight nature of the beams and columns, heavy lifting equipment isn’t normally required during erection. Most elements can be carried so access to confined/remote areas of a property is not an issue.

Reduced foundation costs

The high strength to weight ratio of a cold rolled structure makes the overall building very strong but also lightweight. This reduces the need for expensive foundations, site dependent.


Specialised Structures uses high-tensile, pre-galvanised steel, cold rolled into an incredibly strong C-section, as the structural elements of your building. The columns and beams are bolted together with galvanised base, eaves and ridge plates into a rigid frame. It will be durable and maintenance-free for many years.


Cold rolled steel is completely recyclable. Using cold rolled technology, the energy required to fabricate building frames is extremely low. Also, the low weight – high strength ratio of the product reduces the amount of heavy haulage required for delivery to site.

Future flexibility

As these buildings are bolted and screwed together, dismantling for relocation or cost-efficient expansion is simple.
