The advancements brought about by today's modern technology are benefiting society in many ways. Steel structures occupy a place in…
The quality of the steel structure is uneven, and the price also varies greatly. Many customers don’t know how to distinguish the quality of steel structure materials. Why is there such a significant gap in the price between them, and what is reflected in it? The price of steel structure mainly depends on three aspects: the cost of steel, the other is profit of materials, and the third is the profit of processing. High-quality steel structure, complex and tedious processing, and exquisite workmanship, the price is naturally high.
As for how to judge the quality of steel structure, what is its standard?
The quality of the appearance of the steel structure directly affects the finishing effect of the wall after the entire installation. Therefore, when reviewing the appearance quality of steel structures, you should pay attention to the following aspects:
1. There should be no noticeable damage marks on the outer surface of the steel structure; that is, the maintenance film of the steel structure should not have scratches and scratches;
2. The color of the surface components of the steel structure building should not have pronounced color difference;
3. There should be no debris, plants, oil stains, or other stains on the surface of the steel structure, and there should be no spilled adhesive and oil stains at the dismantling joint;
4. The flatness of the adjacent connection positions of the components of the steel structure and whether the inside is flat without inclination;
5. Whether the sealant used in the steel structure is uniform, lubricated, and has no leaks or breakpoints, the sealing effect must be guaranteed. The use of sealant strips depends on the quality of the strip its anti-aging and sealing performance.
The quality of the corrugated metal sheet also determines the quality of the steel structure building.
The metal sheet needs to be free from defects such as cracks, scratches, and follicles from the surface. Observe the reflective effect of the metal sheet from the front. If it is a hollow metal sheet, pay attention to it. Whether the open spacer is complete enough is generally invisible to the naked eye. When the weather changes, when the temperature difference between indoor and outdoor is significant if the sealing strip is destroyed, fog will form in the hollow cavity, and the temperature difference between the inside and outside will be formed. The bigger, the more apparent.
Steel Structure Packing
The regular steel structure manufacturers will package the steel structure when they are transporting and will indicate the mark on the package, including the steel structure buildings processing unit, the model, name or logo of the product, the date, and the number of manufacturers, And words like “moisture-proof” will be remarked.
Steel component production and steel selection
In the construction process of steel structure buildings, high-strength low-alloy steel is preferred. The yield strength of the steel is less than 270MPa, and the alloy content is less than 5%. It should have formability and weldability. Compared with ordinary steel, high-strength low-alloy steel has not undergone heat treatment, hot working, and cutting, so it is widely used in steel structure engineering construction. At the same time, during the processing and production of steel components, strengthen the control of the reference line and positioning method of steel component assembly and installation, tire frame marking, erection size, and other content, and relevant technical personnel should strictly follow the operating specifications to highlight the integrity and stability of the steel structure project. , Accurately calculate the length and radius of gyration of the steel member to ensure the quality of the steel member.
The quality of steel structure is reflected in the material quality of the steel itself, but the most important thing is to choose a regular steel structure manufacturer. Because no matter how good the steel is, it is difficult to ensure the quality of the steel structure if there is a problem with the fabrication. Regular manufacturers will also choose suitable steel according to the project’s needs, the fabricated equipment is more accurate, and the processing quality will naturally be good. An excellent quality steel structure building will prolong the service life of the steel structure project and does not require frequent maintenance.
