The Engineer's TOOL BOX

Tools to help you size, compare, and evaluate structural steel members. And more!

Steel Shapes→

Section properties, dimensions, and design values for standard steel shapes.

Shear-Moment→

Shear, moment and deflection diagrams for common beam loading conditions.

Pipe→

Area, moment of inertia, section moduli, and weight per foot for hollow pipe.

Take-Off→

Total weight and volume of steel members by quantity and length.

Bolts→

Tensile and shear capacity for standard bolt grades, checked against ASD allowables.
