About MetalReal

Working metal is full of small numbers that decide whether a job goes smoothly or gets scrapped. Cut a bar without allowing for the saw kerf and the last piece comes up short. Bend a bracket without a bend allowance and the flat blank is the wrong length. Quote a railing without weighing the steel and the material cost is a guess. None of it is hard maths — but it’s fiddly, easy to get wrong, and rarely laid out plainly. MetalReal exists to do that arithmetic for you and explain what it means.

Each calculator answers one concrete question. The Metal Weight Calculator turns a shape and an alloy into a weight in pounds and kilograms. The Sheet Metal Gauge & Thickness Converter translates between gauge numbers and real thickness for steel, galvanized, stainless, and aluminium. The Bend Allowance & Flat Length Calculator works out the flat blank to cut before forming. The Metal Cost Estimator puts a price on the stock, the Material Yield & Cut List Calculator counts how many pieces a bar yields once kerf is subtracted, and the Welding Filler & Rod Consumption Calculator estimates the filler a joint will drink.

Around the calculators, the blog and learn section dig into metals and alloys, fabrication and forming, welding and joining, and the tools and finishing of the trade, and the Metalworking & Fabrication Museumis a browsable collection of the metals, the machines, the welding processes, and the iconic structures behind the craft — with every entry, image, and fact drawn from Wikipedia and Wikimedia Commons.

A few things worth stating plainly. MetalReal is independent, and not affiliated with any tool brand, filler-metal maker, or steel supplier. It is supported by advertising, which is how the calculators stay free and account-free. Every figure a tool produces is an educational estimate built from the numbers you enter and standard formulas and density tables — the welding-filler figures in particular are planning ballparks, because real consumption depends on technique, fit-up, and procedure. For anything structural or safety-critical, work to your engineered drawings and a qualified welding procedure.
