Free tools
Steel reference, free to use.
The lookups we needed often enough to build properly. No sign-up, no email gate, no upsell in the middle of a chart. They run on the same shape and weight data behind our software.
12 gauges covered in detail
Steel gauge thickness chart
Every sheet steel gauge in inches, millimetres and lb/ft², with the separate galvanized and stainless series and a sheet weight calculator.
Open the tool →33 standard thicknesses
Steel plate weight calculator
Carbon steel plate from 3/16 inch to 6 inch in standard mill sizes. Weight per square foot, per plate and per order, with optional material cost.
Open the tool →12 connection types
Structural steel connections
Shear, moment, base plate, gusset and splice connections — how each behaves, what it is used for, and what goes wrong. Plus structural bolt grades.

These charts are the free surface of what we build — takeoffs, job costing and bid extraction for fabricators and erectors, running against your own data instead of a lookup table.
