In Today’s scenario of rising cost of steel, it is most essential to use such products that provide optimum utilization such as least possible weight without compromising on the strength and custom lengths and punches for faster application and installation. Cold Roll Formed sections are the perfect replacement for the heavy, unviable traditionally formed sections. Cold-formed sections hold a superior edge in comparison to other traditionally produced sections.
|A Case for Roll Formed Sectiond vis-a-vis convential Hot Rolled Sections|
|Hot Rolled Sections||Cold Rolled Sections|
|Low Strength-to-weight ratio||Very high strenght-to-weight ratio|
|Available without any surface finish||Sections provided with painted, powder-coated, galvanized or polyurethane-coated surface finish depanding on customer's requirements.|
|Sections require frequent maintance||Sections are maintance free owing to application of proper surface finish|
|Self-weight requires heavier sectiond for the structures and its supports there by ioad on foundation||Light section reduce dead load and consequently lighter sections for structures and supports. Thus, the load on fundation is bare minimum|
|High wastage since sectiond are available only in standard lengths and shapes||Sections are factory-finished to avoid wastage|
|Insallation time high since sections need to be cut length nad fabricated to site||Factory-finished sections drastically reduce installation time|
|Only standard sections are available||Optimum sections to meet exacting design specifactions: no over design possible|
|Factory of safety sections available||Additional factory of saftey due to increase in yield strength by cold forming|
oday, due to its superior nature, cold rolled sections have replaced the traditionally formed sections in many modern and conventional industry. These sections are now a lead choice of designers, architects and builders. Some applications of these sections are mentioned as under:
Several different type of sections are used in making of chassis, bus body, body and framework of tippers and trolleys, goods carriers and other private and commercial vehicles.
Pre-Engineered buildings all now apply C and Z purlins for shed construction. Decking profile is used for flooring purpose. Shutter profile is used in rolling shutters.
Solar Mounting Structures:
Cold roll formed sections provide the perfect structural support for solar mounting structures. They trigger significant reductions in overall weight of the structure and increase strength. Plain and Lipped C channels are used as longitudinal supports, cross members and Purlins. Mounting rails and Hat Section are also used as purlin alternatives.
Strut Support System:
Strut profile support system provides flexible and economical support solution for mechanical and electrical services such as in cable tray application.
Strut sections, Lipped Channels, Plain C Channel are used for preparing several types of storage racks.
Furniture and Office Equipment:
Various types of sections are used in furnitures for asthetic appeal and durability. Used in modular seating and partitions etc.
