Bendwright: Sheet Metal Layout

Bendwright is the sheet metal calculator and pattern layout tool for the shop floor. Enter your dimensions and get bend allowances, flat blank lengths, press brake tonnage and full flat patterns for common fabricated shapes, each with a clear labeled diagram.

BEND CALCULATOR - Bend allowance, bend deduction and outside setback - Flat length for any angle, thickness, inside radius and K-factor - Material and gauge pickers with built-in K-factor guidance - Labeled diagram showing exactly what each number means

FLAT PATTERN - Build a part with multiple flanges and bends - Total blank length and the position of every bend line - Profile and flat strip drawings that update as you type

SHAPE PATTERNS Tap a shape, enter your sizes and get the developed pattern with a station table for layout: - Cylinder and cone - Offset (eccentric) cone - Segmented elbow - Tee, including angled and off-center branches - Y-branch - Mitered pipe - Rectangle to round and square to round transitions - Hopper - Tray / box - Sphere gores - Flat oval

PRESS BRAKE TONNAGE - Air bending tonnage from material, thickness, V-die opening and bend length - Adjusts for material tensile strength

TOOLS AND REFERENCE - K-factor calculator from a test bend - Sheet weight - Punch tonnage - Bolt circle coordinates - Arc and triangle solvers - Gauge thickness charts and K-factor tables

BUILT FOR REAL WORK - Inches or millimeters, switch any time - Save jobs and share results as text - Works fully offline, with no account and no data collection - One-time purchase: no subscriptions, no ads, nothing locked

Made for sheet metal fabricators, press brake operators, HVAC and duct workers, welders, machinists, estimators and students.

Results are calculated from standard formulas and typical K-factors. Material and tooling vary, so confirm critical dimensions with a test piece before cutting production parts.
