型钢截面特性

Quick reference for data of various types of steel and combined section of section steel, including model, section size, sectional area, theoretical weight and section characteristics of section steel, which conform to current national standards.
【Application Features】
1. The interface design is simple and intuitive, the functions are clear, and it is highly user-friendly. There is no network traffic consumption;
2. The input adapts to the characteristics of mobile phones and adopts various methods: stepper, segmented selector, roller selector... It is convenient and fast;
3. For the selection of the most commonly used section steel, using the roller is convenient, fast, interesting and has a first-class feel;
4. The data are all taken from current national standard specifications, timely, accurate and detailed;
5. The detailed section dimensions are marked in-situ in the attached drawings, which is clear at a glance;
6. Each type of section steel has a custom page, which provides convenience for the query of non-standard section steel;
7. The dedicated numeric keypad is convenient and fast for input;
8. It is a native application with a small installation size and does not occupy the precious storage space of the mobile phone.

• Combined section of two hot-rolled channel steels (including channel steel face-to-face, back-to-back combination) (calculated according to 《Hot-rolled section steel (GB/T706-2008)》)
• Hot-rolled steel bar (《Dimensions, shape, weight and allowable deviations of hot-rolled steel bars》 GB/T 702-2017)
• Rail (《Hot-rolled rail for railways》 GB 2585-2021, 《Rail for cranes》 YB/T 5055-2014)
【Quick Function】After querying the specified section steel, you can quickly input the length to calculate the weight of the specified length of this section steel; input the calculated length to calculate the slenderness ratio of the member with this section steel.
