A Case for Roll Formed Section vis-a-vis conventional Hot Rolled Sections

 Hot Rolled Sections

 Cold Rolled Sections

Low Strength-to-weight ratio

Very high strength-to-weight ratio

Available without any surface finish

Sections provided with painted, powder-coated, galvanized or polyurethane-coated surface finish depending on customer's requirements.

Sections require frequent maintenance

Sections are maintenance free owing to application of proper surface finish

Self-weight requires heavier section for the structures and its supports there by load on foundation

Light section reduce dead load and consequently lighter sections for structures and supports. Thus, the load on foundation is bare minimum

High wastage since section are available only in standard lengths and shapes

Sections are factory-finished to avoid wastage

Installation time high since sections need to be cut length and fabricated to site

Factory-finished sections drastically reduce installation time

Only standard sections are available

Optimum sections to meet exacting design specifications: no over design possible

Factory of safety sections available

Additional factory of safety due to increase in yield strength by cold forming
