Special Section Steel For Reinforced Concrete

Special steel, steel bars for reinforced concrete belong to small steel. Including hot-rolled round steel bars for reinforced concrete, thermally treated steel bars for prestressed concrete,Section steel and reinforced concrete. Hot-rolled reinforced steel bars for concrete. Cold steel reinforcement. Except round steel,Section steel others are also called rebar. Because the steel surface is rolled into ears or thread bars during rolling,Section steel it is the steel used for reinforced concrete in the construction industry. Reinforcing bars are classified into grades Ⅰ, Ⅱ, Ⅲ,Section steel and Ⅳ according to the material yield point and tensile strength, and the above-mentioned steel bars are used directly.

Heat-treated steel bars for prestressed concrete. Heat-treated threaded steel bars have high strength,Section steel but are not suitable for welding and spot welding steel bars. The steel bars are made of 40Si2Mn, 48Si2Mn, 45Si2Cr and other steels after heat treatment. The nominal diameters are 6, 8.2, 10 Mm. Cold rolled ribbed steel bars are made of Q215, Q235, 24MnTi steel with a nominal diameter of 4-12 mm. After heat treatment, the steel bar should be rolled into a coil and delivered in a heat-treated state.
