Product Introduction:

Q235 steel is a common carbon steel. Q235 ordinary carbon structural steel, also known as A3 steel. Q represents the yield limit of this type of material, and the last 235 refers to the yield value of this type of material, which is approximately 235 MPa. The carbon content of ordinary carbon structural steel is 0.06-0.22%, with less than 0.25% being the most commonly used and belonging to low-carbon steel. Each metal brand represents the minimum yield point for steel grades with a thickness less than 16mm.

H-Beam & I-Beam carbon steel belong to structural material which has high strength and good formablilty. It can afford heavy load after common machining. The structure steel of Eastking steel has reliable mechanical property, good formability and excellent welding performance, which is widely used in various industries. Widely used in architecture, bridge construction, marine craft, railway locomotive heavy machine and other structural parts. Structure steel can be classified as normal structure steel, welding structure steel, pipe steel and building structure.

Mechanical Properties of Q235



Tensile Strength/Mpa




Yield Strength/Mpa



In construction manufacturing, H-shaped steel can be applied to building structures such as houses, public buildings, and industrial plants to resist climate erosion, such as moisture, condensation, and freezing snow. It can greatly improve the stability and durability of buildings.

Used in the field of mechanical manufacturing: H-shaped steel has good bending resistance and toughness, and can be used to make mechanical frames and mold parts.

Application for bridge structure: H-shaped steel has high tensile strength, which can make the bridge structure more stable and sturdy.

Application in shipbuilding: H-shaped steel can be used for electroplating ships, tank ships, and bridge ships, etc. Ensure the structural rigidity and load-bearing capacity of the hull, while also improving its corrosion resistance and appearance.
