  Q355E steel plate and Q345E steel plate 　　Q355E steel plate belongs to low alloy high strength structural steel. Among them, "Q" means the yield strength, and 355 means that the yield strength of this steel is 355MPa, and the yield value will decrease as the thickness of the material increases. Regular thickness 30-300MM, width 2000-2800MM, special width and length can be customized in batches. 　　Q355E steel plate standard: GB/T1591—2018 　　Introduction to the difference between Q355E steel plate and Q345E steel plate: 　　The main difference between Q345E and Q355E materials is that Q345E limits the heat treatment process of the material and must be normalized or normalized rolling. Q345E has no special requirements. It can be said that Q355E is a steel grade extended from Q345E, and Q355E is normalized rolling at low temperature. Steel plate, higher yield than Q345E. 　　The above is the introduction, standard and difference between Q355E steel plate and Q345E st...

  EH36 ship steel plate 　　Ship plate refers to the hot-rolled steel plate used to manufacture the hull structure produced in accordance with the requirements of the classification society's construction rules. 　　Structural steel for hull is divided into strength grades according to its minimum yield point: general strength structural steel and high strength structural steel. 　　The general-strength structural steels in the standards of China Classification Society are divided into four quality grades: A, B, D, and E; the high-strength structural steels in the standards of China Classification Society are divided into three strength grades and four quality grades: 　　A32 D32 E32 F32 ≤50mm carbon equivalent Ceq,% not more than 0.36 　　>50-100 carbon equivalent Ceq,% not more than 0.4 　　A36 D36 E36 F36 ≤50mm carbon equivalent Ceq,% not more than 0.38 　　>50-100 carbon equivalent Ceq,% not more than 0.4 　　A40 D40 E40 F40≤50mm carbon equivalent Ceq,% not more than 0.4 >50-...

  Q345qD bridge steel plate application and grade introduction 　　Q345qD belongs to the bridge structural steel plate, and the implementation standard of Q345qD steel plate is the special technical condition of GB/714.        Q345qD steel plate grade introduction Q=yield point 345 = steel plate yield point value unit MPA q= is the bridge steel plate and the pinyin acronym of Chinese character bridge. D=steel plate grade also D also represents the steel plate is -20 degrees low temperature impact test Same as the implementation of standard bridge slabs, there are also Q235q, Q345q, Q370q, Q420q, Q460q 　　Q345qD steel plates are often used in bridge structure manufacturing, for example; Q345qD steel plates are used as raw materials for bridge equipment manufacturing, bridge structural engineering, and now cross-sea bridges, Shanghai Bridges, Shihe Bridges and Rainbow Bridges.

  Q355DH steel product introduction          1. Q355DH section steel is a new type of hot-rolled section steel, which has the advantages of shock resistance, wind resistance and impact resistance, and has relatively low requirements on the surface quality of steel.          2. Q355DH section steel is a section steel product made of high-quality Q345AQ345B slabs smelted in electric furnace or converter, straightened by straightening machine or automatic cutting machine after heating, and then pickled and polished after cold forming. . 　　3. Q355DH section steel is generally divided into two types: hot-dip galvanized section steel and cold-dip galvanized section steel. 　　4. After the Q355DH steel is pickled, it is generally not pickled. 　　5. The strength of Q355DH steel mainly depends on the height and width of the transverse rib. In the case of the same height, the wider the width, the higher the bending stre...

  Low Alloy Angle Steel 　　Low alloy angles are in the angle family and are not commonly used. However, it is also a type that must be introduced. Low alloy angle steel is a long strip of steel, mainly used in industry, construction and other fields. Such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouse shelves, etc. 　　Low-alloy angle steel is generally classified according to structure, and it becomes the connector between components according to the composition of different stressed components. It can be composed of various stress components according to different needs of the structure, and can also be used as a connector between components. Low-alloy angle steel has good weldability and plasticity, and also has good mechanical strength. Very adaptable in construction.

  Galvanized angle steel 　　Galvanized angle steel is a kind of angle steel, which is widely used in power towers, communication towers, curtain wall materials, railways, road protection, street light poles, marine components, building steel structural components, substation ancillary facilities, light industry and other industries. Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. The cold galvanized coating mainly ensures the full contact between the zinc powder and the steel through the electrochemical principle, and generates an electrode potential difference for anti-corrosion. 　　The advantages of galvanized angle steel are: low cost, durable, good reliability, strong coating toughness and so on. Deeply loved by customers.

  Common sense of angle steel 　　Among the many specifications of steel, angle steel is a very important existence. Angles are long pieces of steel with vertical sides. It plays an important role in construction. 　　Angle steel produced by angle steel manufacturers is mainly divided into two types: equal-edge angle steel and unequal-edge angle steel. Equilateral angle steel is generally more common, and it is also a section steel product with greater engineering demand. On the contrary, in construction, unequal angle steel is not so much in demand.
