Profiles

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.

ALLOYS EXTRUDED FOR STEEL PROFILES

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.
Other industries where extruded Steel profiles are in great demand includes
