Roll Forming Systems for Steel Stud Framing

Structural Steel Building - Steel framing and decks

Steel stud framing refers to the building technique with a basic frame of vertical steel columns and horizontal I beams in the form of a rectangular grid. These grids support the floors, roof and walls of buildings. Steel framing is the basic structure on which other building materials rely for support. It is the strength, durability and sturdiness of steel that make it an excellent choice for framing. The construction of strong high rise buildings and skyscrapers in different states of America has been made possible by light gauge steel framing. The high strength framing steel used in these buildings is fabricated by roll former machines.

Roll formed steel is made by a progressive motion process wherein flat strips of cold steel are passed through a series of matching profile rolls driven in multiple stands. Tandem sets of rolls (referred to as roll stations) shape the metal stock in a series of progressive stages till the desired cross-sectional configuration is obtained. Roll forming process typically eliminates multiple stage production, sub-assembly and finishing operations. Several sub-assembly operations can be continuously combined in a steel stud roll forming machine. The additional operations, such as punching, notching, welding, and bending, that otherwise would have to be performed as secondary operations are incorporated into the roll forming line, minimizing handling and processing costs.

Thanks to the progressive manner in which bending takes place, there is little or no change in the cross sectional area of the work piece. Roll forming does not call for application of any heat and the use of roll former machines adds a strain hardening impact in steel, thereby increasing the yield strength. The process can increase the yield strength of full sections by as much as 70 percent more than virgin metal yield strength.

Thanks to roll former machines, building contractors have effective and economical steel framing solutions for the construction of high rise buildings. For commercial steel framing, roll formed steel has a considerable strength advantage over steel produced through other metal fabrication techniques. Strong bridges and other super structures are also constructed using roll formed steel for basic framing. Structures that have the support of steel stud framing can effectively withstand adverse weather, wind and even the seismic loads caused by earthquakes, hurricanes and cyclones.

With roll forming, the production of high strength structural steel for a variety of engineering applications has been made really simple and cost efficient.

Roll Former Equipment For Steel Framing

Stud and Track Produced by a Roll forming Machine

Stamping, press brake bending and extrusion are some well known metal fabrication techniques. However it is the process of roll forming that is preferred for its technical superiority and cost efficiency for metal fabrication. A steel stud, the C channel and U channel used for steel framing in buildings are all produced by a metal stud rollformer to ensure highest quality of the finished material. In addition to roll forming, a stud roll former machine can also be used for other functions such as material cutting and roll punching.

Roll Forming Machines

A typical steel stud roll former machine has a line with four major sections for specific functions. The entry section or first part of the machine is the place where the material is loaded. The metal in a stud building machine is usually put in sheet form or fed from a continuous coil. The next section has a set of station rollers and this is the segment where the actual roll forming takes place. The steel stud is shaped as it makes its way through the stations. The stud roll formers located here not only shape the metal, but are the very driving force of the machine.

Steel Studs

The third section in a stud building machine is the cut-off press where the steel stud is cut to a pre determined length. Unlike other metal forming techniques, roll forming makes it possible to include cutting of steel channels in a single operation. The final section is the exit station, where the finished part exits the machine onto a roller conveyor or assembly line, and is moved.

Stud building machines that use roll forming to produce metals are very energy efficient as heating of material is not required. Precise and uniform steel studs for framing can be successfully produced with these machines.

Roll Forming Equipment for Steel Studs and Track

Stud and Track in Framing: Benefits of using High Strength Steel Studs

Framing of the structure being constructed is the basic outline which offers support to other materials and makes the structure strong, durable and reliable. The construction of numerous high rise buildings, bridges and other super structures is made possible with the use of steel stud framing. Steel framed structures can effectively withstand adverse weather, wind and the seismic loads caused by hurricanes and earthquakes.

C Channel and U Channel Roll Forming Machinery

Characteristically, steel framing comprises a C channel and U channel fabricated with high strength steel and this material is chosen by the builders due to its typical qualities including:

• Higher strength to weight ratio than most other building materials

• 100 percent recyclable nature

• Stable dimensions that do not expand or contract with moisture content

• Consistent quality

A steel stud being inorganic in nature does not rot and high strength steel channels produced through roll forming technique also do not warp, split, crack or creep. Buildings with steel stud framing have shorter and more predictable construction schedules.

Roll forming proves to be the most apt process for the production of any metal stud. Along with steel studs, it is also used to produce studs, tracks and channels of aluminium, zinc, copper and other ferrous and non ferrous metals. The metals produced by roll forming are also used in a variety of other applications including automobiles, electrical and general engineering works. For a steel stud used in building construction, the stud building machine operating at room temperature adds a strain hardening impact and increases its yield strength to as high as 70 per cent more than virgin metal yield strength.

Stud and Track rollformer machine

Stud and Track used in Steel Framing

The use of steel framing in building construction has several advantages over the traditional reinforced concrete construction. The strength, resistance, durability and resilience of a steel stud make it an ideal material used in construction. Steel is also a non combustible product and so the height and area restrictions that concern combustible materials for a building do not apply to steel.

C Channel U Channel Roll Former

Typically, builders use a C channel with a U channel for steel stud framing in building construction and these channels are produced with the roll forming technique of metal fabrication.

The stud building machine forms the channels at room temperatures to lend extra strength and durability to each roll formed steel stud. The process of roll forming augments metal studs with adequate rigidity and has discrete advantages over other techniques for production of metal stud. As against press brake process, stamping and extrusion, roll forming is better for fabrication of a C channel and U channel used in steel framing because:

• It can produce parts with greater lengths, limited only by the length of the material being fed into the stud roll former
• It provides greater consistency and uniformity to the profile of metal stud
• It offers the flexibility to include all secondary operations in the same process of metal forming
• It gives a superior surface finish to each steel stud

Using the right process to produce steel framing materials is important and roll forming proves to be the most efficient and cost effective for same.

How to make steel studs by roll forming

Stud Roll Former

Steel framing refers to the building construction technique with a basic frame of vertical steel columns and horizontal I beams, made in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The construction of strong high rise buildings is made possible largely due to steel framing.

For light steel framing, thin sheets of high strength galvanized steel can be formed into steel studs to be used as building material in commercial, industrial and residential construction and for various other applications. The dimension of the room that requires framing, is established with horizontal tracks that are anchored to the floor and ceiling to outline the room. The vertical studs are arranged in the tracks, usually spaced 16 inches apart, and fastened at the top and bottom.

In most of the constructions, builders use C-shaped stud with a U-shaped track. Framing members are usually fabricated in a thickness of 12 to 25 gauge. The wall finish is anchored with the two flange sides of the C-shaped stud the thickness of which varies between 1-1/4th inches to 3 inches.

The steel used for framing is roll formed at room temperature to lend it extra strength and durability. Roll forming augments steel with adequate rigidity and gas distinct advantages as compares to metal forming techniques such as press brake process, stamping and extrusion. Some of the typical benefits of roll forming include:

• Producing metal parts with greater lengths.

• Consistency and uniformity of profile.

• Very close and high tolerance.

• Flexibility to include all secondary operations in the same process of metal forming.

• Providing superior surface finish to the metal parts.

Steel framing is the basic structure on which other building materials rely for support and it certainly needs to be strong. The roll formed steel studs and tracks can ensure this strength in light steel framing.

Benefits of Structural Steel Framing

Structural steel has come up in a big way as the preferred ‘superior construction material’ for constructing the framework of a residential or commercial building. Not only is it the paramount and the most viable building material but it also sets a quality bar against which all other construction materials are measured.

Structural steel has a plethora of advantages. The erection of steel framing involves a rapid design and fabrication process, thereby optimizing the construction cycle and minimizing the time required to complete a construction project.

Structural steel has a phenomenal strength to weight ratio. This means that while buildings constructed around structural steel framing systems display high strength, they are much lighter, and consequently require less elaborate and expensive foundations

Framing systems made of structural steel and induced with decking and fire protection features, on an average cost almost 7% lesser than those constructed of concrete. It is no surprise then that structural steel has reigned as the market leader in the cost bracket for over three decades.

Structural steel has great aesthetic appeal and is loved by architects for its strength and modifiable traits. Moreover, the machines and equipment used for designing structural steel framing systems are readily available and are far ahead in efficiency and productivity compare to those used by other framing systems. When subjected to design details and architecture master plans, structural steel’s grace, slenderness and sturdiness create masterpieces.

Structural steel, being 100% recyclable, is highly sustainable and can be re-used without any processing to make a variety of products in future. In fact it has a grand 68% recycling rate in the industry. Moreover, it creates almost 18% less scrap and waste when compared to lumber. Additionally, unlike other framings, structural steel framing systems can be modified for the purpose of expansions, new additions or customizations.

Choosing steel framing ensures that your framing system is inorganic and therefore will never rot, crack or split or worse still, be vulnerable to moulds, fungi or termites. Nor will it expand or contract owing to moisture content. Importantly, it offers better resistance to seismic forces causing earthquakes.

Steel studs and joists are made of uniform quality structural steel fabricated under controlled conditions to provide maximum strength during the production stage itself. This ensures straight steel walls with perfect corners that do not need modification post installation.

All these benefits of using structural steel framing for residential and commercial constructions create a win-win situation for both the builder as well as the end customer.

Forming Quality Structural Steel for Framing – The Working of Roll Forming Machines

Roll forming process is the most widely used methodology to form high strength steel for framing in buildings. The roll forming machines fabricate the required configurations out of long strips of coiled steel. Apart from roll forming, these machines also perform a number of other functions such as material cutting and roll punching.

The basic roll forming machine has a line that can be segregated into four major parts. The first part or the entry section is the place where the material is loaded. It is usually put in sheet form or fed from a continuous coil. The next section comprising of station rollers, is the segment where the actual roll forming takes place. It is here that the stations are located and the metal shapes as it makes its way through the process. Station rollers not only shape the metal, but are the very driving force of the machine.

The third section of a basic roll forming machine is the cut off press, where the metal is cut to a pre-determined length. Due to the speed at which the machine operates and the fact that it is a continuously working machine, flying die cut-off techniques are not uncommon. The final section is the exit station, where the finished part exits the machine onto a roller conveyor or assembly line, and is moved.

Roll forming machines are energy efficient as they do not consume energy to heat the material—the metal can be shaped at room temperature. It is also an adjustable process and may be used for projects of varying time duration. The fabrication of precise and uniform parts becomes possible through roll forming.

Steel Framing Machine – Roll Forming Technique

Building construction with steel framing has many advantages over the traditional reinforced concrete construction. The typical properties of steel viz. its durability, flexibility and strength make it an ideal material for any product application that requires resistant metals. Steel is also 100 percent non-combustible. The height and area restrictions that pertain to combustible materials do not apply to cold-formed steel.

Roll forming is one of the most widely used processes for forming a variety of metals including copper, zinc, brass, titanium and high strength structural steel. In this process, a strip of metal usually in coil form is continuously passed through a series of roller dies and progressively formed to get the required shapes. In many cases, the process eliminates multiple stage production, sub-assembly and finishing operations. Numerous sub-assembly operations can be continuously combined together with the use of roll forming equipment.

Roll Forming is also an economical choice for many companies that aim to streamline their production and reduce total costs. The high-speed continuous nature of roll forming is an advantage for fabricating large volumes of metal. Savings are realized through the need for fewer component parts and post-production operations along with reduced manufacturing cost. With the use of roll forming technique, the need for secondary operations such as notching and deburring is completely eliminated.

Roll formed steel has a structural strength advantage over steel formed through other processes. Thin walled hollow and semi-hollow shapes can also be produced by roll forming in a more simple way than the alternative processes.

Steel Framing – Steel Produced by Cold Roll Forming

Steel framing refers to the building technique with a basic frame of vertical steel columns and horizontal I beams, fabricated in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The construction of high rise buildings is made possible largely due to steel framing.

It is the high strength structural steel that allows the architects to actually bring to life the structures that they design in blueprints. Steel provides that strength and resistance to buildings which is hard to achieve with other materials in a cost effective way. The strength, durability, design flexibility and adaptability of structural steel make it the material of choice in building construction.

Cold roll forming is an extremely methodical and highly efficient mechanism to fabricate high strength steel. The process of cold forming employs a series of matching profile rolls driven in multiple stands, through which metal strip is passed without application of heat. Each pair of rolls progressively shapes the metal, until the final pair produces the required profile. The cold roll forming process adds a strain hardening impact in steel, thereby increasing the yield strength. The process can raise the yield strength of full sections to as high as 70% more than virgin metal yield strength.

Steel produced with the roll forming technique can be used in a variety of engineering applications including building construction, automobiles, electrical and general engineering works. Indeed, high strength steel is the most basic requirement of these industries and the most suitable way to produce the material is roll forming.
