About the App

Kouzaitap(Metal Calculator) makes quick work of steel math. Pick a JIS shape or enter your own dimensions and get instant weight in kilograms plus surface area in square meters. It’s a practical, no-frills helper whether you’re checking a takeoff, planning coating, or doing a back-of-the-envelope sanity check—on your phone, tablet, or even on a desktop through BlueStacks.

App Features

• Fast weight calculations — Compute steel weight based on kg/m and kg/m². Enter key dimensions and get results immediately without hunting through tables.
• Surface area for coating — See the exterior area you’ll need for paint or galvanizing. If an area can’t be determined for a given input, the app clearly shows that it’s not calculated.
• JIS shapes at your fingertips — Browse a wide range of Japanese standards: plates and sheets, H/I beams, channels, equal and unequal angles, flat/round/square/hex bars, bulb flats, T-beams, sheet piles, and more.
• Pipes and tubes coverage — Includes common designations like STK, STKR, STKM, SGP, STPG, plus stainless options such as SUS304TP and SUS316TP.
• Stainless and light-gauge sections — Work with hot-formed and cold-formed stainless sections, as well as light C, Z, lip channels, and hat profiles used in building work.
• Cross-section properties — Get basic section data for selected shapes to support quick checks and comparisons during design or estimation.
• Save and export — Keep your calculations for later, share via email, or export as text/CSV when you need clean numbers for reports or spreadsheets.
