Calculators, SDS2 report templates, and AI drafting aids for detailers, fabricators, and erectors. Every result prints its formula and assumptions — nothing is a black box.
One steel puzzle a day, built from real AISC values and weld symbols. Same puzzle for everyone, new one at 6 AM Mountain.
Name the shape, check the weight, read the weld →Report Writer templates SDS2 doesn't ship — specs and sample output now, files rolling out.
All templates + custom AI reports →Sixteen field-and-office calculators, six of them full-screen for a tablet on the bench. Formulas printed under every result.
All 16 calculators →Describe the problem in plain words — get a clean RFI or a parsed weld symbol.
5 AI runs a month with an account →Bolt and weld capacity per AISC 360-22, ASD and LRFD, coefficients shown.
Both tools + design values →Find structural steel fabricators by state and service. Honest sourcing, no lead-selling.
Browse all listings →SDS2 gives you 21 bolt reports and zero saw lists. We build the missing ones, check every field path against the verified SDS2 catalog, and give them away. Don't see yours? Describe it in plain English and the AI generator writes the Report Writer file for you.
Every calculator, all nine RFI templates, the SDS2 report library, the fabricator directory and the Daily Detail work with no account and no sign-in. That does not change.
An account exists for one thing: the AI tools — RFI drafting and weld parsing. Those cost real money every time they run, so they are metered at five a month. Email sign-in, no password, no card.
A copy-ready RFI or worksheet, a calculator or SDS2 template, and directory updates. No filler, unsubscribe anytime.
