Steel Edging

Steel Edge Rolling & Conditioning

Steel edging, also known as steel edge conditioning is a process in which the edge of a steel coil is rolled to the desired shape, eliminating the slit burr edge. The slit burr edge is rolled and formed into the strip through the process to make steel coil edging where the edges are safe for exposed applications.

Steel Coil Edging Process

Siegal Steel produces edged conditioned steel strip by utilizing flat rolled master coils to exact customer specification. By contouring the slit edge from slitting, Siegal Strip goes through a series of flattening rolls, round or square edge coil & strip, additional temper rolls, camber straighteners, and leveling rolls.

Edge rounding steel is a process completed after slitting and contours the product. It is useful to note that steel edging does not scrape the steel. Steel coil edging rolls the slit edges of slit material with a series of dies that rolls the slitting burr together to form a uniform edge.

The most common types of steel that require edging:

Edge Profile Types

Siegal Strip, our version of steel edging, may be produced with a number 3 (slit edge), number 4 (round), number 5 (square), or number 6 (deburred) type edge. Common terms for steel edging edges are round, square, and deburred.

Number 3: Slit Edge

Approximately square edge with slitting burr intact.

Number 4: Round-Cornered Edge

Rounded edge - may have slitting fracture visible along the edge.

Number 5: Deburred Edge

A number 3 edge with the slitting burr healed over.

Number 6: Square Edge

Squared with radial corners - may have slitting fracture visible along the edge. 


Benefits of Steel Edging

There are a number of benefits to utilizing the steel edging process on your material, including:

  • Improved part functionality
  • Safety edge
  • Improved aesthetics
  • Tighter gauge tolerances



Steel coil edging is for a wide variety of applications including:

Steel Coil Edging FAQ's

Q: What is edging of a steel coil? 
A: Steel coil edging is the process of rolling the edges of a steel coil to the desired shape, eliminating the 
slit burr edge. The slit burr edge is rolled and formed into the strip making the edges safe for exposed 

Q: What is a slit burr edge? 
A: A burr is an edge defect on a steel coil produced during the slitting process. It is a sharp ridge sticking 
out aways from the rest of the slit cut.

Why Siegal Steel Edging?

When using oscillating coils in a stamping operation

loading times are reduced by up to 100%

Our customers find that steel edging creates a very close tolerance product for many applications. Whenever our customer needs tighter width tolerances than industry standard, steel edging can be the answer. Siegal Strip, produces tighter than standard gauge tolerances by means of gauge correcting thickness variations. We do this by using our temper mills in line on our edging equipment. Our powered edging dies alter the width tolerances per customer specifications and our camber straighteners and levelers assure a perfectly straight tight tolerance product. This is steel edging at its best.

Cost Savings of Steel Edging?

Steel edging assures that our customers receive closer than standard width and gauge tolerances than a slit steel product. This means that die life is enhanced.

Our customers save money by ordering an edged steel product in their desired multiple. Our customers can save even more money by buying Siegal Strip, our steel edged product, in coil. Finally, our customers can save the most by using oscillate traverse wound steel edging. By welding the tails of steel edged coils together and wound in a traverse manner, customers may reduce their loading times by up to 100%. The cost savings ensure that traverse wound Siegal Strip save more than the process cost. Steel edging at its most economical.
