Unravel complex steel calculations with this essential iPad and iPhone application for flat-rolled steel buyers. Unravel: Flat-Rolled Steel Calculator makes it easy to verify steel coil and sheet specs. Calculate the weight of a steel coil without a scale, convert gauges to decimals instantly, and find the number of sheets in a bundle. Convert easily between imperial and metric units for both coil and sheet measurements. Input the cost per CWT to compare prices. Works with all coated and uncoated steel. Whether galvanized, aluminized, prepainted or cold rolled material, use this app for quick and simple weight, cost and yield calculations. Use this app to: - Calculate coil and bundle weight without a scale - Verify that your purchase is to spec - Find the area, total length or price per square foot of material - Convert between gauges and decimals - Convert between imperial and metric units There are several critical variables that drive the true cost of flat-rolled steel, including weight, thickness and zinc coating. Use the Unravel Flat-Rolled Steel Calculator to verify that you have the right steel for the job.

I'd also like to override material ##/ft from mill certs for a particular purpose, rather than just view the acceptable range. I've been working on this app myself, now I can get on with my list. Thanks, ### 4/5 — Not Bad *2013-01-30* Better now with the update but it would be better with an Aluminum coil option and slitting calculations. I would also like an area to put DFT for coated product that would increase the OD. ### 5/5 — Nice update! *2013-01-15* It's great to be able to save and load my calculations. This helps me out a lot. ### 1/5 — Bad Update *2013-01-15* I just updated this app and now will not open. What's up?? ### 5/5 — Good Solid App *2012-05-29* The app is good - giving good information, correct calculations and ease of use. ### 5/5 — Cool Coils *2012-05-02* Very handy little gadget, I can see this app getting a workout! ### 5/5 — Very useful app. *2012-03-10* It's great to obtain coil weights and footage specially on coils that are being restocked. ### 4/5 — Very useful tool... *2012-03-07* Would love to have a Hot Rolled Uncoated profile and the ability to calculate theo nom weights per piece under the Sheet section, but other than that, great app for the steel industry. ### 4/5 — Great app *2011-12-20, version 1.0.5* This is an excellent app and it performs great, but it could use a few more features. I wish it could calculate cutting coils lengths in half, thirds etc. and the weight differential for multiple slit widths including trim scrap. ## Frequently asked questions about Unravel ### Does Unravel have ads?
