SteelFlow: Metal Calculator

Calculate metal weight from dimensions, check material costs, and turn a project into a PDF quote. SteelFlow works offline with no account required. CALCULATE METAL WEIGHT Choose a profile, enter dimensions and quantity, and see unit weight, total weight, surface area, volume, and the formula behind the result. SteelFlow supports common profiles including plate and flat bar, round, square, hexagonal and octagonal bar, round, square and rectangular tube, angle, channel, I/H sections, T sections, and custom cross-sectional area. ESTIMATE REAL PROJECT COST Price material by kg, lb, meter, foot, or piece. Add waste, processing charges, transport or other fixed fees, markup or margin, and tax. Currency-aware rounding keeps totals practical for real quotes. BUILD PROJECTS, NOT LOOSE CALCULATIONS Save multiple material items into a project, duplicate and reorder them, update pricing, and keep every dimension and assumption traceable. See total quantity, weight, material cost, fees, tax, and quote total in one place. SHARE PROFESSIONAL OUTPUT Create a polished PDF quote or export a machine-friendly CSV material list. Add company and customer details, terms, validity, and notes before sharing. MATERIALS AND UNITS THAT FIT YOUR WORK Use built-in densities for carbon steel, stainless steel, aluminum, copper, brass, titanium and more, or create custom materials. Work in metric or imperial units without rebuilding a calculation. PRIVATE AND OFFLINE No account is required. Project and material data stays on your device by default, core calculations work offline, and versioned local backup helps you move or restore your records.

SteelFlow Pro unlocks unlimited projects and items, custom materials, company details and quote terms, CSV export, unbranded PDF quotes, versioned backup, and bulk pricing with one non-consumable purchase—no subscription. IMPORTANT Weights and prices are theoretical estimates based on your inputs, reference densities, and common engineering formulas. Verify material grades, current standards, supplier data, drawings, and actual stock before purchasing, fabrication, transport planning, structural design, settlement, or contract use.
