The following sections can be used to help you order your parts over the phone. These are great guides that will show you what information is important and the different methods your parts can be formed. Simply click on one of the following tabs below for the material shape you would like to use.
When ordering angles you will need the following information:
Size of angle and material type:
The size of the material and material type is very important when rolling angles. Angles need to have room to expand and material like Aluminum will easily break during this expansion. The size of the legs are also important. Knowing if an angle will break or not requires an experienced roll man that knows the behavior of material during the process. Make sure to give us a call before ordering to make sure your requirements do not need special processing like heat treating or a modification to material thickness.
Angle methods of rolling and diameters:
Angles can be formed two different ways. Easy way and Hard way. The following sections will detail how a angle roll method is described and will show cross sections to help you request angles over the phone or email without the requirement of a drawing.
Easy Way:
An Easy Way or EW angle will have its leg pointing out as shown in the image below. This will give you one inside diameter and 2 outside diameters. This means that an inside diameter size should be given when ordering EW angles.
Hard Way:
Also listed as HW, Hard way angles are a much more difficult form of rolling angle due to the limited amount of pressure angles can handle using this method. Hard way angles have the leg facing in has shown in the following image. This creates one outside diameter and two inside diameters. When ordering HW angles make sure to use the outside diameter.
Unequal Angles:
Angles can also be formed with obtuse legs sizes or unequal angles. When ordering these types of angles you must declare if you wish to use the Easy Way or Hard Way method plus you must specify which leg points to the inside of the diameter for Hard Way and the outside of the diameter for Easy Way.
When ordering flat bar you will need the following information:
Size of Flat Bar and material type:
The size of the material and material type will determine how flat a flat bar will be after rolling and the possible amount of deformation. Flat bars are limited by the roll machines ability to hold the bar square as it rolls. Make sure to give us a call before ordering to make sure your requirements do not need special processing like heat treating or a modification to material thickness.
Flat Bar methods of rolling and diameters:
Flat bars can be rolled in two different methods. Easy Way (EW) or Hard Way(HW).
Easy Way:
An Easy Way or EW flat bars are shaped like a "wedding band". This method of rolling allows us to use breaking equipment and methods to roll most bars all the way to the end. This eliminates waste and time required to cut.
Hard Way:
Hard Way or HW flat bars are shaped like a "washer". Hard way flat bar require tangent to allow for flat ends created by the roll machine. The amount of flatness depends on the material size, type, and diameter.
When ordering I-Beams you will need the following information:
Size of angle and material type:
I-Beams are classified by Size and Weight. An example would be a S5 x 10#. This is a standard I-Beam with a 5" flange signified by the S5. 10# allows us to check the thickness dimensions which is .214" for our example. Aluminum I-Beams do not follow this standards with uncommon sized I-Beams.
I-Beam methods of rolling and diameters:
I-Beams can be formed two different ways. Easy way and Hard way. The following sections will detail how an I-Beam roll method is described and will show cross sections to help you request I-Beam over the phone or email without the requirement of a drawing.
Easy Way:
An Easy Way or EW I-Beam will have its leg pointing towards and away from the center of the diameter as shown in the image below. A drawing is required since I-Beams have multiple Easy Way and Hard Way diameters.
Hard Way:
Hard Way or HW flat bars are shaped like a "washer". Hard way flat bar require tangent to allow for flat ends created by the roll machine. The amount of Also listed as HW, Hard way I-Beams apply pressure directly to the weakness part of the I-Beam. The thickness of the webbing is very important when forming I-Beams with this method. Hard way I-Beams have many inside and outside diameters measurements so a drawing is required to meet your requirements.
When ordering channels you will need the following information:
Size of Channel and material type:
Channel sizes are classified by the type, size, and weight per foot. An example would be C6 x 8.2#. The is a "C" Standard Structural Size Channel with a 6" Depth and a weight of 8.2 lbs per foot. This allows us to communicate the web thickness and flange length which is important for roll forming. The standard sometimes varies especially for Aluminum Channels that use a different standard.
Channel methods of rolling and diameters:
Channels can be formed with three different roll methods. The standard Easy Way (EW) and Hard Way (HW) methods are the most common, but channels can allow be rolled on edge. When selecting material if is important to consider web thickness when rolling on edge and flange widths when rolling EW or HW. When placing an order the weight of the channel may be changes to prevent deformation.
Easy Way:
The Easy Way or EW roll method has one inside diameter dimension and two outside diameter dimensions. Make sure when ordering to use the proper diameter to make sure your requirements are met.
Hard Way:
The Hard Way or HW rolled channel has one outside diameter and two inside diameters. Make sure when ordering to use the proper diameter to make sure your requirements are met.
On Edge Channel:
On-Edge rolling of channel is one of the most difficult methods to roll form channel. This may cause deformation of the channel include a twist. This sometimes requires the channel to be flatten after forming. Due to the even number of outside and inside diameters a drawing is required to make sure your requirements are met.
