Software Introduction:

This software is free to use. No registration is required, no installation is necessary, there are no copyright restrictions, and there are no pop-up advertisements. It has a bilingual interface (Chinese and English) and is compatible with all versions of Windows operating systems.

This software mainly has 6 major functions: international steel bar query, custom section parameter query, 2D planar concrete section query, unit conversion, interpolation tool, and AutoCAD drawing plugin.

At the same time, all functions have bilingual interfaces, making it convenient for engineers from both domestic and international markets to use.

2026-4-13 Update Content: : New steel bar libraries for Canada, Japan, and South Africa have been added, and the main dimensions of the sections have been previewed.

2026.3.10 Update Content: Added data for American standard W-shaped steel.

Main Function Introduction

1. International Steel Bar Query

(1) The countries and regions covered include: Chinese standard (China), European standard (Europe), British standard (British), American standard (USA), Australian standard (Australia), and Indian standard (India).

(2) The steel bars that can be queried include: H-shaped steel (wide flange H-shaped steel, medium flange H-shaped steel, narrow flange H-shaped steel), I-beam steel, angle steel, channel steel, circular tube section, rectangular tube section, and square tube section for parameter query.

(3) The parameters that can be queried for the steel bars include: steel bar external dimensions, unit length weight, cross-sectional area, and cross-sectional mechanical property parameters.

2. Customized Section Parameter Query

H-shaped, square tube, and circular tube can all have customized section dimensions, and corresponding various section parameters can be queried.

3. 2D Planar Concrete Section Query

Various sections can be selected, including rectangle, hollow rectangle, triangle, trapezoid, circle, circular ring, T-shaped, I-shaped, C-shaped, and L-shaped sections. Corresponding section parameters of various sections can be queried.

4. Wind Load Conversion

Wind pressure conversion is provided for different wind speeds, different recurrence periods, different measurement intervals, and different wind speed measurement heights.

5. Unit Conversion

Provides unit conversion for length, area, volume, force, stress, mass, and specific gravity.
