Rolled Formative

Steel in its basic slab form requires rolling processes to enable its formation into sheet metal form. Once in this form it can receive more rolling to alter its thickness further.

First, as an overview, there are two types of rolling performed on basic steel. One is flat rolling the other is profile rolling. These two types produce final products that differ greatly from each other. In both processes, steel passes through a set, or sets, of rollers.

One product from flat rolling is sheet or strip metal. Another product from this type of rolling is plate steel; of a thickness 3/8″ or greater.

Profile rolling produces a final product of a rounded rolled shape. This could be a round rod, a tank, a pipe, or a cylinder.

Rolling of sheet metal is the bending continually of the piece along a linear axis. This causes alteration of the original form of the sheet; it becomes deformed. The material receives progressive shaping and contouring as it passes through a pathway of rollers.
This product, steel now in a thinner flat state, is part of our everyday life. From the outside metal of your car, to the roof above your head, its uses are varied. To get sheet metal to this state, roll forming takes place upon it. Different roll forming machines prepare this material for the different products it will comprise.

Modern machines that handle the forming minimize the actual human handling of the metal. A new consideration to manufacturers today is the minimizing of downtime from the set-up of these machines. There are different sizes and types of sheets that require manipulation. A machine that can handle these different types with minimum set-up time for each is valuable.

From a technology standpoint, sheet metal fabricators look for versatility in fabricating machinery. They want machines that can form continuously, dependably and fast. They want high output for efficiency.

They do not want to spend inordinate amounts of time in set-up, preferring pre-tooled systems. This way they can run through different types and sizes of sheet metal on one machine. They want machines that can handle a changeover quickly so excessive downtime is not an issue. Advanced machinery that can handle different roll widths with quick re-tooling are desired.

Improved automation of the fabrication process is one contributor to reducing downtime. Today’s sheet metal fabricating machines can utilize more than one tooling set. These separate tooling sets can run alongside each other with different cut-offs and form presses. That’s a great example of retooling time eliminated.

Another important consideration, in forming parts or pieces, is the elimination of poor quality pieces. Poor quality pieces become scrap, which means salable output is less and costs are greater. Technologically advanced machinery, which produces accurate, quality work, will keep a company profitable. State-of-the-art metal forming processes produce work within required specifications. They also maintain the integrity of the material.

Any forming machinery that can increase production serves a company well. A system that minimizes inventory usage through scrap reduction is beneficial to the profit picture. Today’s manufacturers want sheet metal forming systems that offer both.

Roll forming is a continuous metal forming process taking sheet, strip, or coiled stock and bending or forming it into shapes of essentially identical cross section by feeding the metal between successive pairs of rolls that increasingly shape it until the desired cross section is completed adding both strength and rigidity to lightweight materials. The process adds both rigidity and strength to the roll formed material. During the roll forming process, only bending occurs. The thickness of the metal is not changed except for a slight thinning of the material at the bend radius.

The roll forming process characteristics include:

• Its common usage to mass produce mass long metal pieces with relatively close tolerances,
• The utilization of ductile workpiece materials, softer metals,
• Working with materials that are usually less than 1/8″ thick and 20″ wide,
• The capability to produce desired workpieces at a forming speed of 100 feet per minute (fpm),
• Its strong suitability to produce decorative and structural metal products often for roofing and siding.

Roll forming machines are now being produced so that for similar products such as stud and track profiles, a new set of profile rolls is not required. This is achieved by the mill being split along its center line and the web, flange and ear sizes are set using a control panel which moves the mill rafts centrally to increase or decrease the aforementioned features.

Custom Roll Forming benefits

• High-speed, high-volume fabricating process,
• Infinite number of shapes possible,
• Thinner cross sections and practically any length can be roll formed,
• uniformed cross sectional dimensions throughout the length of the part,
• Almost any metal can be roll formed
• Eliminates multiple operations – secondary operations can be done at the same time, e.g., punching, notching, etc., thus saving valuable time
