Refined steel, also known as refined steel, fine steel, high-precision steel, precision steel, etc. There are various types of refined steel, including conventional rectangular tube, rectangular steel, T-shaped steel, as well as specially customized trapezoidal steel, special-shaped steel and so on. Refined steel is different from ordinary steel and ordinary hot pressing round modification. According to the needs of the project, it develops and produces Strong system steel profiles with customized engineering properties (shape, strength, span, thickness and node) and made through a kind of special process in order to meet the design requirements.

Cold roll forming is a relatively advanced production technology in the industry. At present, there are not many domestic manufacturers who master this technology, which is different from hot press quenching round modification products. The products of the round to square transformation can only be called "right angle steel pipe" at most, not "exquisite steel". There are obvious shortcomings in the products of the circular modification, such as uneven wall thickness, excessive R angle, uncontrollable surface roughness (after grinding), limited strength improvement (process), low yield, unable to accurately control temperature and pressure, single finished product specification, appearance can not meet higher requirements, etc.

Different Strong system roll cold forming refined steel profiles solve the above problems.

1. The refined steel profile through rolling and cold bending has reliable and high strength. Therefore, in terms of space application and scene selection, special-shaped facade profiles with more slender and larger span can be customized.

2. After being processed by rolling cold bending process, ordinary steel has controllable high strength and accurate wall thickness, and can customize products with different wall thickness and special-shaped specifications.

3. After the ordinary steel is treated by the rolling cold bending process, the outer R angle is less than 0.3mm, which is comparable to the aluminum profile, and the strength is better than the aluminum profile.

4. Roll cold formed refined steel has high yield, fast delivery speed, flat surface, beautiful appearance and straight lines.

Refined steel profiles began in the curtain wall industry and are developing into more fields. Strong system is exploring more new scenes suitable for refined steel profiles.

The rise, development and advantages of fabricated refined steel profiles.

Strong system further processed the refined steel profiles treated by cold bending process, and the refined steel profiles with better performance were born. The application of patented Tenon Technology of Strong system has greatly improved the bending, compression and distortion resistance of refined steel profiles, which can reach several times that of ordinary steel profiles. The patented technology of mortise and tenon connection adopts NC machine processing during processing, which can not only ensure the accuracy but also ensure the beautiful appearance. Compared with the existing rolling technology, the specifications of finished products are diverse, the section can be changed arbitrarily, and the product models are more abundant, which can meet all the dimensional requirements of designers. The mortise and tenon bridging steel plate used by Strong system can greatly improve the bending, compression and distortion resistance of the finished steel column, improve the quality of the finished steel column and prolong the service life of the finished steel column. All components are accurately dimensioned, with factory error of ± 1mm;

Advantages of mortise and tenon fabricated components:

1) High efficiency: compared with traditional methods, factory production is not affected by bad weather and other natural environment, the construction period is more controllable, and the production efficiency is much higher than manual operation;

2) High precision: the error of fabricated building reaches millimeter level;

3) High quality: factory production of components, greatly improving the quality;

4) Direct installation on site without any secondary processing, which can greatly reduce the dependence on labor;

5) Dry on-site assembly, saving water, electricity, materials and environmental protection;

6) Have a relatively complete standard design system;

7) Good seismic performance of the structure;

8) The building area can be increased;

Strong system's refined steel profile and different refined steel have created a new benchmark in the industry.
