Steel Weight Takeoff

Type a material list line just as it stands. You get the weight with its unit, and the required quantity by grade and category.

■ Reads material list notation as written 2-H-400×200×8×13×4000 / PL-9t / L-65×65×6 / [-100×50×5t / φ22×700 — count, symbol, dimensions and length in one line. Full-width digits and shop names such as "channel" are read too.

■ Never mixes up the unit Sections, flat bars and round bars in kg/m, steel plate in kg/m², cut plate in kg. When units differ inside one take-off sheet, each row carries its own unit.

■ When one designation points to two sections, no answer is given H-400×200 points to two standard JIS sections (396×199×7×11 and 400×200×8×13). They differ by 16.7%, so no result is shown until you pick one. The app never picks quietly for you.

■ Totals come in two tiers Design quantity and the required quantity (design plus allowance), laid out by grade and category. Standard allowances: sections +5%, steel plate +3%, bolts +4%, anchor bolts 0% (Standard Method of Measurement for Public Building Works, MLIT Japan). Change them to your in-house standard if you have one.

■ Put the take-off sheet on paper (Pro, one-time purchase) A4 PDF, and CSV you can paste into your own estimate. Add a project name and hand it to the general contractor or the fabrication shop.

■ Sources are shown on screen Sections and unit masses come from JIS G 3192:2008 (hot rolled steel sections) and JIS G 3466 (carbon steel square tubes); density of steel is 7.85. The edition is printed on screen.

[Shapes] H-section, channel, equal angle, unequal angle, square tube, steel plate, cut plate, flat bar, round bar

The material list, project name and allowance rates you enter stay on this device. They are not stored in iCloud, so they do not move to a new device.

Apart from that, only crash reports and anonymous usage statistics are sent. The contents of your material list, project names and dimensions are not sent. The app shows no advertising.
