### Engineering Bulk Solids Handling Systems

If you are in the powder and bulk solids material handling industry, then you know that engineering bulk solids handling systems entail achieving complicated designs to ensure material flow problems do not occur. Sometimes finding the most cost-effective steps to Read more…

### How is Section Modulus Used in Bending Steel?

To determine if a steel section can be curved you need to first determine its section modulus and then see if you have the correct bending equipment. Section modulus is the direct measure of the strength of the steel. Bending Read more…

### How to Quickly Calculate the Length of a Helical Curve

Here’s a quick lesson that will take you back to your days of high school algebra, and may help in estimating material needed for helically rolled projects. The curved arc length of a helical item, used for a number of Read more…

### How to Calculate the Radius of a Long Steel Section Curved Less Than 180 Degrees

The definition of a radius of a circle is the length of a line from the center of a circle to its perimeter.  When measuring a curved steel section (e.g. a curved steel angle, beam, bar, channel, etc.), you can Read more…

### Calculating the Developed Length of a Rolled Cylinder

Designers, detailers, and fabricators commonly debate the correct formula for a blank length of bent plates.  A trial run is always good practice when forming on a press brake because metals stretch so differently on different setups. This confusion does Read more…

### How to Use Your Smartphone to Measure the Pitch of a Stair Stringer (Curved or Straight)

Don’t hang up your carpenter’s square quite yet; it will still be useful in the layout of your treads. But today’s smartphones have mini gyroscopes called MEMS (microelectromechanical system) gyros (that’s “JIGH-ro, not the Greek food GEE-ro). These sensors allow Read more…

### How to Develop the Blank Flat Length for a Cylinder

To develop the blank flat length for a cylinder rolled from sheet or plate is quite simple: Essentially, you should calculate the centerline arc: (Outside Diameter – Thickness) x 3.1416 = Length of Plate Required (Inside Diameter + Thickness) x Read more…

### Pickup/Waste Considerations When Designing with Rolled Steel Shapes

When designing for the use of rolled steel shapes in any application, architects and engineers must take into consideration the fact that most bending and curving processes require a certain length of material on each end of the curve.  This Read more…

### How to Identify a Steel Beam Size

Without the help of mill markings to identify a given steel beam, you should measure the height (A), the flange width (B), the flange thickness (C) and the web thickness (D).  With that information you can go to any number Read more…

### How to Check the Diameter of a Metal Pipe

The Actual outside diameter (OD) of a pipe is larger than its name:  Nominal (nominal means “in name only” from Middle English nominalle meaning “of nouns).  Use the table below to cross reference the Actual OD (outside diameter) of the Read more…
