PRACTICAL TOOLS

Steel Tools

Choose steel coil or plate weight calculators, a material-specific gauge chart, or a zinc coating mass converter with formulas and examples.

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.

Weight Calculators

Coil cross-section and density symbol leading to a weight scale.

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.

Plate length, width and thickness connected to a weight scale.

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.

Tube cross-sections showing outside dimensions, bore and wall thickness.

Steel Pipe & Tube Weight Calculator

Calculate round, square and rectangular steel tube weight in kg/m or lb/ft, with custom density and a sourced NPS / Schedule lookup.

Round, square, flat and hexagonal bar sections with dimension arrows.

Steel Bar Weight Calculator

Calculate round, square, flat and hex steel bar weight from dimensions, length, quantity and density in metric or imperial units.

Processing Calculators

Master coil width divided into daughter strips, edge trim and remaining width.

Steel Coil Slitting Calculator

Plan multiple steel coil slit widths, edge trim and remaining width; calculate utilization, daughter coil weights and a complete mass balance.

Converters & References

Three schematic thicknesses illustrate why 16 gauge depends on the material.

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.

Coated-sheet sections connect coating-mass units g/m² and oz/ft² with conversion arrows.

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.
