Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important A633 Grade A high-strength low-alloy structural steel heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.
Structural steel angles (along with other types of steel sections like A36 channels, I-beams, bulb flats and A633 Grade A high-strength low-alloy structural steel) are widely used in construction as a rigid reinforcing material for concrete monolithic elements of high-rise framed buildings, as well as for critical and wide-span support elements in industrial and civil applications. Angle steel bars are also used for door and window framing, arches and other architectural elements. Steel angles are also used for room decoration, as well as in the heavy machine building and furniture industries.
API 5L Gr.B steel plate is one mainly of Steel for large diameter pipes,API-Gr.B steel is manufactured using premium grade of raw material. These products A633 Grade A high-strength low-alloy structural steel are used to flow steam, water, oil and various petrochemicals substance in various petrochemical and chemical industries. These Steel Seamless Pipes are widely appreciated for high performance and less maintenance.
A633 Grade A high-strength low-alloy structural steel, Wear-resistant steel plates are composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal circumstances, the thickness of the alloy wear-resistant layer of the wear-resistant steel plate is 1/3-1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against external forces. And the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.
