What's Included
One membership unlocks every tool in the members area — with more on the way.
HDG Plant Design
Size a complete galvanizing plant from an investor's targets — kettle, furnace, chemical line, building and cranes — and cost it from a live multi-supplier price database.
HDG Service Cost Calculator
Galvanizing cost per tonne — zinc pickup, consumables, energy, labour and margin, from live zinc pricing and your plant's parameters.
Steel Products Calculator
Weight, cost and design for profiles, standard sections, grating, wire rod and mesh — with estimation and shop-drawing exports.
Pickling Optimizer
Manage your HCl pickling system — bath concentrations, dosing, dilution, regeneration and the Kleingarn relationship.
HCl Converter
Convert HCl titration to % w/w, normality and g/L, and interpolate any aqueous HCl property from the standard chart.
Vent & Drain Hole Planner
Mark vent and drain holes on photos of fabricated steel, size them from section volume, and export a driller-ready PDF.
More tools on the way
Zinc bath management, dross & ash tracking and KPI dashboards are coming — included in your membership as they launch.
Why this isn't just another calculator website
These tools come out of running real galvanizing plants — not a textbook.
Built on the plant floor
Designed by a galvanizing engineer with 21+ years in production and 9 plant projects. Every tool solves a problem actually hit in operation.
Standards, not opinions
Grounded in ASTM, ISO, EN and SSPC/NACE — the same references your inspectors and clients already use.
Made for decisions
Costing, bath control, hole layout, plant sizing — operational answers you act on, not academic theory.
One toolkit, always growing
Six tools today, more each month — all included, all maintained, all behind one login.
