New frontiers in technology have been met by our Samco roll forming machine, which has been designed and manufactured with the latest in technology to produce only the highest quality cold formed sections. It is the first rollformer in South Africa to produce the full range of lipped channels on one mill, thus improving on delivery time. Other than its full range of lipped channel sections, the rollformer can also produce a vast variety of open sections.
The Samco rollformer has an inline punching system, which is a punch anywhere Quad Head system that offers a range of round and slotted holes. A second inline 40ton hydraulic press has been made available for customised punching. An added feature of the punching system is auto programming from AutoCAD drawings. Another impressive and cost effective component device is its inline hard stamping and inkjet marking capabilities.
Manufacturing process description.
The Samco roll forming line is an ultramodern self-setting, high speed, precision cold forming line with an automatic quad head in line punch anywhere facility that can also be used to cut small sheets in high volumes.
Productivity comparison to competitors :
The Samco roll forming line incorporates a number of unique features which either exceeds or is on par with the very best available lines in South Africa and are as follows:
Dual production capabilities:
This Samco line produces a flat sheet or punched sheet before it is fed into the roll former. Steelrode has requested Samco to incorporate a side discharge blank kickoff system to use the machine as a cut to length line for small blanks for the automotive and building industries, which are normally done by hand on a steel guillotine.
Line speed
The effective line speed
is 60 meters per minute
Size variation on
cut sheets
Lengths from 200mm to
7620mm
Widths from 150mm to
700mm
Size variation on
cold formed sections
Web from 75mm to 450mm

Punch holes in line
The Quad Head punch anywhere system makes holes of 14mm, 18mm and 22mm with the fourth punch for slotted holes measuring 18mm x 40mm. The four post interchangeable punching unit allows Steelrode to incorporate other nonstandard holes required by customers for specific application (e.g. racking legs) with slots in them for a shelve to hook in. Accuracy of these holes is obtained via CAD drawings from customers feeds; this is linked directly from a PC and eliminates any human error.
Automatic change
