14mm JIS SM520B plates with low price

Our company was founded in 2000, which initially committed to providing high-quality steel JIS SM520B plates products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export JIS SM520B plates steel to the international market, opening up the international steel market.

Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.

Non-destructive flaw detection of steel plates is a test method for inspecting the JIS SM520B plates surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used JIS SM520B plates steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.

JIS SM520B plates, Chinese material Q235B is one of the most widely used carbon steel in the world. Some like to compare its strength with other equivalent steel grades. We need to take care that the Q235B steel strength varies with thickness. For the min. yield strength of Q235B steel plate: it is 235Mpa if thickness ≤16mm, 225 Mpa for thickness 16-40mm, 215 Mpa for thickness 40-60mm, 205 Mpa for thickness 60-100mm, 195 Mpa for thickness 100-150mm, 185 Mpa for thickness over 150mm. The tensile strength of Q235B steel plate is 375-500 Mpa.

Our company was founded in 2009, and has been committed to steel business since its establishment. Over the years, the company's performance shows a good development trend, with a wide range of customers in the government, domestic and foreign markets. The company has always been in line with the tenet of "based on trust and win with quality", focusing on the market demand, with a long-term vision, with years of hard work and trustworthy operation, and the support of the majority of JIS SM520B plates businesses and customers, has won the unanimous praise and trust of the industry and customers!
