Profile
Extruded Steel Profile
In Extruded steel profiles a vast range of standard profiles are available. The material used in such
Steel shapes profiles can be carbon steel as well as stainless steel. Extruded steel shapes gives its
users a number of advantages that includes reduction in the needs of machining, finishing and scraps
etc.
The steel profiles are typically hot extruded to the required specifications. In a steel mill,
roller tables are used to for transportation of steel profiles between the workstations. A typical
production line includes a double roller table between an extruder and the packaging machine. It is on
the first roller table that extruded steel profiles get cut with shears. While on the second table, a
hot saw is used to finish the cutting of the profiles.
Design of the Extruded Steel Profiles
|
Following fundamental points are to be given preference
while designing the shape of extruded steel profiles in the most economical manner.
|
• Facilitation of a smooth steel flow through the extruded shape die, Total
avoidance of sharp edges.
• Achieving precise section reproduction, define the rounded corners along with
fillets.
• For designing a groove, ratio of depth to width to be kept very low. A one-to-one
ratio is to be maintained.
• For accomplishing the desired non-symmetrical shape, all hole requirements is to
be eliminated.

Application of the Extruded Profiles
|
Hot extruded steel shapes are popular in material
handling industry. Two popular applications include thick web and flanged structural
steel shapes using extruded carbon steel channels and I-beams for use in fork lift
mast rails.
