?The square bar is a solid bar usually made by pressure processing into various shapes and sizes. It is widely used in construction, machinery manufacturing, agricultural machinery and other fields. In construction, square bar is often used in light steel structures, such as steel roof truss, civil residential skeleton, etc. In addition, square bar is also used in the production of various machinery parts, agricultural machinery accessories and tools. The main types of square bar include hot rolled square bar and cold drawn square bar. Hot-rolled square bar has a side length range of 5-250mm, while cold-drawn square bar has a side length range of 3-100mm?12. ?

Hot rolled square bar: The hot rolling process is adopted, which can refine the grain of the steel, destroy the casting structure and help eliminate the defects in the structure. ?

Cold-drawn square bar: it is formed by cold processing such as cold drawing and tensile bending at normal temperature. This process will not cause harm to the coating on the surface of the steel, and has strong plasticity.

A construction company based in the United States was buying a batch of square bar for its new project, and the company's purchasing manager found our website while searching the Web for rail suppliers. He noted our extensive experience and good reputation in the supply of steel, and after reading a detailed description of our products, the purchasing manager left us a message via the contact form on the website, hoping to purchase a batch of 50x30 hot rolled square bar. After receiving the customer's message, our online customer service immediately took action to get in touch with the customer, in the initial communication we learned that the customer needs to buy a batch of high-quality stable and long-term use of square bar.

After many times of email communication, after fully understanding the specific needs of the customer's project, our sales team introduced the characteristics of our 50x30 hot rolled square bar to the customer:

- Material: Q355B is a kind of low-alloy high-strength structural steel, the main components include carbon, manganese, silicon and other elements.

- Strength: the yield strength reaches 355MPa, the tensile strength is between 470-630MPa, and the bearing capacity is high.

- Corrosion resistance: After special treatment, a dense oxide film is formed on the surface of the square bar to effectively resist corrosive substances in the atmosphere.

- Weldability: Q355B square bar has good weldability, and the mechanical properties of welded joints are equivalent to that of the base material, which is suitable for large-scale construction.

Application:

- Building structure: widely used in high-rise buildings, Bridges, industrial plants and so on.

- Machinery and equipment: used to manufacture heavy machinery, mining equipment, etc.

- Transportation: Structural parts for railway vehicles, ships and other means of transportation.

With our detailed product information and technical support, the customer finally chose our square bar. In order to ensure that the product quality meets the requirements of customers, we also provide samples for inspection. After confirming the final order, we quickly started the production and packaging process. At the same time, in order for customers to receive products in a timely manner, we cooperate with a number of international logistics companies to carefully plan the most economical and efficient logistics routes. Through the organic combination of sea and land transportation, we successfully reduce logistics costs and ensure that products can be delivered to customers on time and safely. After several months of close cooperation, the customer feedback that our square bar shows excellent results, not only easy to weld in the construction but also high bearing capacity effectively reduce the customer's cost.
