TradeCalc SA

TradeCalc SA is the ultimate offline-first calculations and material estimating companion designed specifically for South African artisans, fabricators, boilermakers, pipefitters, planners, and mechanical engineers. Whether you are on a heavy industrial construction site, working in a fabrication workshop, or drafting a commercial tender, TradeCalc SA provides rapid, highly accurate sizing and weight calculators at your fingertips. No internet? No problem. TradeCalc SA is a 100% offline-first utility. All critical engineering data, physical properties, and standard piping specifications are stored locally on your device. Work with confidence in remote plant sites, underground shafts, or areas with poor cellular coverage, completely free from data charges or third-party cloud service costs. CROSS-FUNCTIONAL ENGINEERING MODULES: • PIPE WEIGHT ESTIMATOR Instantly calculate theoretical weights, cross-sectional areas, and external surface areas for steel and metallic pipe runs. Simply select or input your custom outer diameter (OD), wall thickness (WT), and total pipe length. Supports direct entry in millimetres and output summaries in kilograms. • PLATE & SHEET WEIGHT ESTIMATOR Rapid material take-offs for steel, stainless steel, aluminum, brass, or copper plates. Configure your dimensions (length, width, thickness) and materials to get precise mass estimates and paintable surface areas instantly. Ideal for sheet metal fabrication and structural framing shops. • FLANGE BOLT & GASKET MATRIX Access standard flange tables (SANS, ANSI, BS) by nominal bore size and rating. Instantly retrieve standard flange layouts, including required bolt quantities, bolt diameters (e.g., M12, M16, M20), bolt lengths, and recommended joint/packing ring dimensions. Say goodbye to carrying dense physical pocket books to site. • INTEGRATED UNIT CONVERTER Accelerate onsite unit conversions without leaving the app. Convert fluidly between metric and imperial systems across length (NB, inches, mm), mass (kg, lbs), pressure (bar, MPa, kPa, psi), and temperature (Celsius, Fahrenheit). • PROJECT ESTIMATION ORGANIZER Save and organize individual calculations under specific project or contract names. Compile multiple pipe, plate, or bolt items into custom bills of materials. • RAPID CSV EXPORT Generate clean, tabbed data spreadsheets from your saved projects. Export calculation summaries via CSV directly to your clients, site foremen, or estimating software. WHY TRADECALC SA? • South African Industry Aligned: Configured with standard material densities and reference dimensions common in local engineering. • High-Contrast Industrial Theme: Styled with a dark slate gray backdrop and radiant industrial yellow typography, optimized for high legibility under harsh solar glare on outdoor plant sites. • 100% Client-Side Persistence: Your project data, plans, and estimates stay securely inside your device-specific database.
