Fabora is a fabrication calculator toolbox for fabricators, welders, pipe fitters, sheet metal workers and metal trades. Work out steel and metal weights, weld settings, pipe offsets, PCD flange holes, cut lists, plate nesting, steel beam checks and sheet metal flat patterns in one app that works fully offline, with no account and no sign-up to get started.

Stop juggling five calculator apps, spreadsheets and scraps of paper. Everything a workshop or site needs sits in one place, ready even when there is no signal.

ALL 21 TOOLS
- Steel and metal weight calculator: plate, bar, tube, pipe, sheet, beam and standard sections in steel, stainless, aluminium and more

- Welding calculator: starting amps, wire size, shielding gas and heat input for MIG, TIG, stick (MMA) and FCAW
- Pipe offset calculator: travel, run and cut length for simple and rolling offsets, elbows, mitres and saddles
- PCD and flange hole calculator: bolt circle diameter, BCD, pitch circle spacing, chord lengths, hole coordinates and a live 1:1 drawing, backed by a multi-standard flange library
- Flat pattern development: cones, cylinders, pipe branches, square to round and transitions, with true 1:1 DXF and fit to page PDF cutting templates
- Stock cutting optimiser: cut lists with minimal offcuts, kerf allowance and a visual bar layout
- Plate nesting: nest parts onto plates and sheets with yield, weight and cost
- Steel beam calculator: quick checks for moment, shear, deflection and section sizing by region
- Press brake calculator: bend allowance, K factor, tonnage, flat length and bend deduction
- Section library: 2,600+ UK sections with weights (UB, UC, PFC, SHS, RHS and more) plus EU, US, Indian and Australian libraries
- Price sheet and quote: cost a job, mark it up and generate a branded quote PDF
- Tank volume calculator: box, cylinder and cone bottom tanks with dip charts
- Stair stringer designer: UK and US straight flight set-out with drawing, DXF and PDF
- Baluster and divider calculator: even spacing, clear gaps and a shop mark-out list
- Arc calculator: solve a curve from any two of radius, angle, chord, rise or length
- Digital angle finder: live sensor, camera protractor and photo modes
- Photo markup: measurements, arrows and notes on site photos
- Screen ruler and bolt gauge: calibrated mm and inch ruler with washer sizing on screen
- Offcut store: track usable offcuts and reuse before you buy
- Colour matcher: match a photo to the nearest RAL or BS colour
- Unit converter: dimensions, loads, stress, welding and structural units

A NOTE ON SAFETY
Weld settings are starting points and beam figures are quick checks, not certified engineering. Always confirm against your own measurements, material data and a qualified engineer where required.
