Advantages of CRF
When a steel section is cold-formed from flat sheet or strip the yield strength increases as a result of this cold working, particularly in the bends of the section. Some of the main properties of cold formed steel are as follows:
- Lightness in weight
- High strength and stiffness
- Ease of prefabrication and mass production
- Fast and easy erection and installation
- Substantial elimination of delays due to weather
- More accurate detailing
- Non shrinking and non creeping at ambient temperatures
- No formwork needed
- Termite-proof and rot proof
- Uniform quality
- Economy in transportation and handling
- Non combustibility
- Recyclable material
- Panels and decks can provide enclosed cells for conduits.

The effect of cold working is thus to enhance the mean yield stress by 15% – 30%. For purposes of design, the yield stress may be regarded as having been enhanced by a minimum of 15%. Some of the main advantages of cold rolled sections, as compared with their hot-rolled counterparts are as follows:
- Cross sectional shapes are formed to close tolerances and these can be consistently repeated for as long as required.
- Cold rolling can be employed to produce almost any desired shape to any desired length.
- Pre-galvanised or pre-coated metals can be formed, so that high resistance to corrosion, besides an attractive surface finish, can be achieved.
- All conventional jointing methods, (i.e. riveting, bolting, welding and adhesives) can be employed.
- High strength to weight ratio is achieved in cold-rolled products.
- They are usually light making it easy to transport and erect.
Competitive Advantages of Cosmic CRF Project
Cosmic CRF project’s competitive advantages over other suppliers of CRF members to the railway sector are assessed to include the following:
- Savings in transportation cost, as CRF are bulky items, due to close proximity to the wagon manufacturers who are located in eastern India (Private Players – Texmaco, Titagarh Wagons, Jessop, Hindusthan Engg & Industries; SU Players – Burn Standard, Bharat Wagon & Engg, Braithwaite & Co Ltd.). The other three units are located far from the end-using sectors: TI at Uttarakhand, Pennar at Patencheru in AP and DTH Ltd in Pune, Maharashtra.
- Cosmic CRF has procured the latest range of CFR machines which, we are given to understand, are capable of making complex shapes to very close tolerances.
- Lastly, the CRF machines will be capable of processing thicker sheet/plates and hence cater to the new products under introduction by the Railways.
Cosmic CRF’s project is thus expected to enjoy a competitive edge over the existing manufacturers.
