Steel types & specifications
Start with product form, material, manufacturing process and surface treatment. A galvanized coil can have a cold-rolled carbon-steel substrate: form, grade and coating describe different parts of its specification.
Steel Coil: Types, Dimensions & Specifications
Decode a steel coil specification: base grade, thickness, width, coating, surface, ID, weight, standards and inspection documents.
Steel Sheet & Plate
Specify sheet and plate by supply route, grade, BMT, tolerances and finish, with a drawing-to-specification table and two worked order examples.
Carbon Steel
Distinguish carbon steel from mild steel, compare carbon levels, and read grade, condition, forming, welding and corrosion requirements.
Galvanized steel coil
Specify galvanized coil by substrate grade, base-metal thickness, G90 or Z275 coating context, spangle, surface treatment and forming needs.
Calculators & thickness charts
Calculate coil, plate, pipe, tube and bar weights, plan coil slitting, or convert gauge and coating values. Each tool explains units, formulas and estimating assumptions.
Steel Coil Weight & Length Calculator
Calculate steel coil weight, strip length, outside diameter and PIW in metric or imperial units, with formulas, examples and density assumptions.
Steel Plate & Sheet Weight Calculator
Calculate rectangular steel sheet or plate weight, total area and quantity from dimensions and density in metric or imperial units.
Sheet Metal Gauge Thickness Chart & Converter
Look up material-specific gauge thickness in mm and inches, compare steel columns and download the CSV with 4 and 38 gauge source notes.
Zinc Coating Weight Converter & Reference
Convert coating mass between g/m² and oz/ft². Read G90 and Z275 with their ASTM or EN context and total-both-sides measurement basis.
