ShapeBook is the ultimate structural steel quick reference and estimating software for steel industry professionals. ShapeBook is based on the AISC Steel Construction Manual 15th Edition plus the addition of large pipe sizes, small bar size materials, plate, flat bar, round bar, and square bar in US imperial and metric units. ShapeBook is the steel shape reference software of choice among steel construction professionals and students.

If you are looking for an affordable solution for estimating steel and coatings, look no further. The ShapeBook software is much more than just a steel shape reference. It includes a powerful estimating tool for steel, and coatings. The "Material Takeoff Tab" extends the weight, surface area, and pricing for all of the items in your material list".

The take-off material list can be easily revised and manipulated. List items can be deleted, re-priced, and sorted. The take-off material list will automatically expand and contract in length as the ShapeBook widow size is adjusted. The lists can be saved to files on your drive and loaded back into ShapeBook or imported into spreadsheet or database software. The "Print List" command prints the list with a custom title, date, page numbers, line numbers, and includes column and row outlines. The lists can be used as an advanced bill of materials if needed.

This new Windows 11 release of ShapeBook and ShapeBookWith2D3DSteel provides a handy touch interface for Windows devices, uses version 15.0 of the AISC database, and continues the 20 plus year legacy of the ShapeBook and 2D3DSteel software.

StairCalculator is a dimension calculation tool for building structural steel and aluminum stairs. It provides imperial or metric dimensional calculations for steel stair stringers, including length, miter, and bevel cuts, running dimensions for tread holes in the web and running dimensions for handrail post holes in the flange. With a choice of three framing conditions at the top and bottom, bolted or welded treads, and stringer material from the AISC Shapes Database v15.0 November 2017 edition, StairCalculator can calculate dimensions for almost any stair stringer configuration. The calculator accepts negative dimensions for some inputs so you can move the stringer above or below the finished floor and above or below the nosing line giving StairCalculator the flexibility you need when drawing, checking, and fabricating steel and aluminum stairs.
