Plan with the right numbers.
Practical calculators for materials, fabrication, lighting and power. Clear inputs, visible assumptions and useful results—without an account.
Fabrication tools
Material Weight Calculator
Calculate metal plate, bar, pipe, tube, angle, channel and I-beam weight with editable density, quantity and cost.
Open calculator ↗Multiple DXF Nesting Tool
Upload several 2D DXF parts, set quantities and preview a sheet layout, utilisation and material balance in your browser.
Open calculator ↗Lighting & power
Built for initial engineering decisions.
Compare alternatives, check supplier quantities and prepare a clear requirement. Each tool explains its formula and limitations. Product selection, actual fabrication and final electrical design still depend on the offered configuration and verified operating conditions.
