The material flows more laterally, once the forming angle approach 90-degrees. This increases load against the forming rolls and creates many problems, like marking or scuffing, end-flare, twist with asymmetrical profiles, and camber, or bow. We started as the first pipe bender and roller in California, expanding our operations into a full-scale custom metal fabrication provider. If you’re looking for experts who can work with you and guarantee the results you’re looking for, we’re here to guide you throughout the process.
What we do at Jorgenson Metal Rolling and Forming
For a Roll Forming Tooling design, considering all the variables and applying “theory” whenever possible is vital in producing a good running product, with minimal start-up problems. Because the roll forming process has a seemingly limitless capacity to produce complex profiles with just as many variables, a high percentage of designs are one-of-a-kind. Past experiences, correctly applied, are still the key ingredients to the design and development of these applications. There are numerous types of metal bending techniques, and the correct procedure depends on the material and thickness of sheet metal that needs to be bent. Our team will also analyze your project prerequisites and determine the best method to reach excellent outcomes.
Easy Install
Patented three-rung design as well as industry leading mud relief design. We need to know what are the requirements and what application is for the job. After We will put our 70+ years of design, application and finishing to use.
Art Technology
The angles shown are how much forming is being done at each pass. Chromium Industries Incorporates state of the art computeraided design and also have laser scanning measurement control toachieve maximum performance and satisfaction, for instance. Avina, a former racer, has spent the last decade turning wrenches for top riders on the West Coast, as well as building cool project machines, such as this Lobo project. Avina was contacted by Francisco Vera of Rosarito, Mexico, in Baja California about a year ago saying he found an old Lobo 250r and wanted it restored.
Cons of Rolled Roofing
Again, these examples are only a general rule of thumb for typical roll formed bends. Our in-house facility is equipped with innovative technology, ensuring your projects are completed precisely and consistently. We can guarantee that our metal bending and rolling services accomplish the outcomes you’ve been looking for. These structural steel products are also available in aluminum and high-performance alloys for sturdier and more durable results that last.
If you do embark on a rebuild, document it with pictures and share it with us. Because who knows, if we like it, we might show it off in the pages of Dirt Wheels, but we will want to ride it first. It was complete and not missing any parts, but it was completely worn out too. For this Lobo 250R Roll supplied new lower front A-arms and bushings all the way around before things were sent off to ECP for powdercoating back to its original red color.

The pre-cut lengths must self-feed through every pass without damaging the lead edge of the strip. A good rule of thumb is to try to design all roll passes to self-feed even when running coil stock. The mill operator should not have to feed a new coil and “pry” the section into the next pass. In other words, a mixture of science and art is still very prevalent today in this industry.
Today, both businesses are expanding with the times, but still have a passion for the roots of the sport and collaborated on an incredible project machine built by Kevin Avina. Roofing with MSR is often your cheapest roofing option, as the material's cost is low and the labor cost can be as low as free if you do it yourself. Materials are limited to little more than the rolls of roofing and 11 gauge roofing nails. The conventional way of roofing a house is with individual composite (asphalt) shingles. Rolled roofing is vaguely similar in that it is also an oil-based asphalt product.
Our roll-forming services also achieve complex bending geometries for unique projects. With the drive diameters chosen, the vertical centers are 7.060” and fall between the 4” to 8” range. The maximum roll diameter shown is based on the required “flange” needed for smooth material transition from the previous pass. It is important to check that this maximum diameter does not interfere with the mill base or any other maximum diameter from an adjacent pass. The location of the profile on the roll space, roll widths, and spacer lengths are also determined in this layout. When developing the flower the designer must consider the correct number of passes.
One example is saturated felt, which is builders-grade felt impregnated with asphalt and used mainly as an underlayment. Care should be taken to limit the amount of lateral and vertical movement the material is subjected to from pass to pass, especially lateral movement. Note how this flower progression is forming more at first and less towards the end.
With pre-notched applications, caution should be taken not to overly increase drive diameters, because this may lead to increased part lengths and/or distorted notches. Metal forming and press-brake bending is done in-house using steel plate, sheet metal and other structural shapes, such as tube bending and pipe bending. We are currently serving customers in Orange County, Los Angeles, San Diego, San Bernardino and across the nation. Call or email us for information on how we can provide you with fast, friendly service for your metal rolling and forming needs. Mainly used to fabricate large parts found in the construction sector, this metal bending technique is utilized to form cones and tubes in different sizes, shapes, and radius bends. Since 1984, Jorgenson Metal Rolling and Forming has been serving the metals industry in Southern California.
Most rolling machines employ two rollers where the workpiece is fed through two rollers. Afterward, the workpiece will come out on the other side with a curve. The operator will reverse the rollers and run the sheet metal back on the opposite side to enhance its curves until the desired angle or bend is reached. Rolled roofing (or roll roofing)—also known as MSR—comes in rolls of 100 square feet. Rolled roofing is easy to obtain and can be found at all home improvement stores. One MSR roofing roll is usually about 36 feet long by 36 inches wide.
Under the rider, Ceet Racing Products recreated their famous desert seat that 30 years ago put them on the map. For long-distance desert racing, a taller seat is a must so the rider doesn’t get worn out from standing and sitting all day. These were developed by Doug Roll and the engineers at Elka exclusively for this chassis.
For controls, Roll Design footpegs give a solid platform for the rider to do his stint, while Works Connection levers and cables provide butterysmooth operation. Flexx handlebars were a good addition, since this product wasn’t even invented until well after the 250R ceased to exist. Those bars were connected to a Roll Design steering stem and damped by a GPR stabilizer. Although over the years ITP’s Holeshot tire technology has improved, these are still some of the best tires you can buy.
The rolled-edge wheel is the strongest design you can get before adding a beadlock or strengthening ring. While rolled roofing is cheap and easy to install, its resale value is perilously low when it is used as roofing on occupied structures. Rolled roofing is best installed on unoccupied structures, such as sheds, shops, garages, and other outbuildings. Before you dash down to the home improvement store and pick up a few rolls, you should be aware of the significant disadvantages that come along with the advantages of this product. Forming a bend that does not have a roll holding the inside corner, is called “air”, “blind”, or “ box” forming. When this occurs, forming the remaining angle from bend #2 helps to reduce distortion in the radius of bend #1.
Many roll designers have different approaches to both design and development (testing of tooling), and amazingly enough, there is more than one way to successfully form a profile. However, there are common design practices that must be understood and applied to the design process, coupled with a certain degree of “magic” (gained through previous experiences). These services can handle tight tolerances without affecting the integrity of the product.
