## What is Steel?

Created by a senior structural engineer. 10+ years building intuitive tools from real-world experience.
Quick check of section data of various types of steel and section steel combination, including section steel model, section size, section area, theoretical weight and section characteristics, which comply with the current Chinese national standards.

Application characteristics:
1. the interface design is simple and intuitive, the function is clear and easy to use. No network traffic consumption;
2. the input adapts to the characteristics of the mobile phone in a variety of ways: stepper, segment selector, roller selector... Convenient and fast;
3. the most commonly used section steel is selected. The use of rollers is convenient, fast, interesting and has a first-class feel;
4. the data are collected from the current national standards and specifications, timely, accurate and detailed;
5. the detailed size of the section is marked in situ in the attached drawing, which is clear at a glance;
6. each type of profile steel has a user-defined page to facilitate the query of non-standard profile steel;
7. special numeric keypad, convenient and fast input;
8. native application, small installation size, does not occupy valuable storage space of mobile phone.

### 4/5 — 没有吨表面积

*2026-07-13*

能否增加吨表面积

### 2/5 — 少

*2025-03-17*

没有热扎方管的吗？

**Developer response:** 应用主要收录国标热轧型钢、冷弯型钢等及常用焊接H型钢。

### 1/5 — 不好用

*2023-12-07*

理论重量不准，偏低

**Developer response:** 理论重量都是取自国家标准，标准号标注于首页。请与标准对照。

### 4/5 — 1

*2022-12-10*

没有方管

**Developer response:** 有的，在冷弯矩形管模块。

### 5/5 — 能增加钢板计算吗？

*2021-07-27*

能增加钢板计算吗？

**Developer response:** 您是指变截面钢的重量计算？ 您可取变截面钢两端的高度平均值，查询得到米重，然后进入重量计算页面输入长度即可得。 比如  6000 长的 (300~600)X220X8X10 ，您可以查询截面 450X220X8X10 ，进入重量计算页面输入 6000，可得总重 369.2kg。

### 4/5 — 半截面面积矩

*2021-04-21*

强烈建议添加半截面面积矩参数

### 5/5 — 型材重量不正确

*2020-12-21*

型材重量不正确

**Developer response:** 请与最新国家标准比较（标准号标注于App首页列表中）。网上随便找的不是过期就是地方标准或者企业标准或者胡乱拼凑的。

### 2/5 — 理论重量差别问题

*2020-09-14*

为什么截面特性里热轧H型钢和网上找出来的理论重量有出入？

**Developer response:** 请与最新国家标准比较（标准号标注于App首页列表中）。网上随便找的不是过期就是地方标准或者企业标准或者胡乱拼凑的。请参照现行国家标准。

### 4/5 — 希望出计算书导出功能

*2020-03-28*

希望出计算书导出功能

**Developer response:** 您好，此App主要为查询功能，除了简单的重量计算附加小功能，并没有计算书可供导出。至于截面力学特性的计算，导出意义不大，若需要可查询相关材料力学书籍中公式。

### 5/5 — 槽钢型号不全

*2020-03-19*

槽钢型号没有轻型槽钢 还有一些理论重量好像不对 望改进！

**Developer response:** 国家标准已经淘汰了轻型槽钢。理论重量都是按国家标准提供的公式计算或原数据录入的，不知你的参照数据出自何处。App首页每种型钢均注明了采用的国家标准，欢迎对照验证。
