Rolled plates are one of steel sheets, and are actually thin steel sheets that are long and narrow and supplied in rolls. The coil and flat plate are almost like a cut-and-pack cold hard coil plate. The hot-rolled coil plate is obtained by pickling and cold rolling. It can be said to be a type of cold rolled coil. Cold-rolled coil (annealed state): The hot-rolled coil is obtained by pickling, cold...

The cold-rolled coil is made of hot-rolled coils as raw material and rolled at room temperature below the recrystallization temperature, including plates and coils. Among them, the ones delivered in a row are called steel plates, also called box plates or flat plates; the ones delivered in a long length and in a roll are called steel belts, also called coil plates. Cold-rolled coil (annealed state...

Seamless steel pipes have hollow cross-sections and are widely used as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, coal gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipes have a lighter weight when the bending and torsional strength is the same, and are an economical cross-sectional steel. It is widely used to ma...

Square Rectangular pipe is a name for square pipes and rectangular pipes, that is, steel pipes with equal and unequal sides. It is made of strip steel after process processing. Generally, the strip is unpacked, flat, curled, welded to form a circular tube, and then rolled into a Square Tube from a circular tube and then cut to the required length. Also known as square and rectangular cold-bent hol...

Anti-corrosion steel pipes refer to steel pipes that can effectively prevent or slow down chemical or electrochemical reactions during transportation and use. According to manufacturing process classification (1) The manufacturing process of seamless steel pipes can be divided into: hot rolling (extrusion), cold rolling (pulling), and hot expansion steel pipes. (2) Welded pipes can be divided into...

Angular iron is a long strip of steel with the two sides perpendicular to each other. There are differences between equal Angle Steel and unequal angle steel. The two sides of the equal angle steel have equal widths. Its specification is expressed in millimeters of edge width x edge width x edge thickness. For example, "∟30×30×3", it means an equilateral angle steel with a side width of 30 mm a...

H-shaped steel is an economical and efficient profile with more optimized cross-sectional area distribution and more reasonable strong weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light str...

There are many types of specifications and models of light round steel bars. Different specifications and models, their diameters and tensile strengths are also different. When choosing light round steel bars, you must make the correct choice based on the actual construction environment, construction plan, construction needs, etc. When purchasing bright round steel bars, in addition to paying atte...
