Q: What does "M" mean?: The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..

Q: Does the profile include H?: Profiles include section H steelThe online quote H steel and profiles in the angle of groove separate quotation, mainly because H steel has great use compared with the other, and the demand is relatively more, but in some cases, and H type steel I-beam can also substitute for each other.

Q: What does "BH" mean?: BH is welded to H just, and RH is hot rolled H steel.

Q: Elastic modulus of section steel: The elastic modulus of steel is 2.1 * 10^7N/cm L.

Q: What kind of steel is used in steel columns?: Section I and H of steel reinforced piles belong to the common section shapes in steel reinforced concrete piles. I and H type steel piles can be used in horizontal load and vertical load bearing. The steel pile has stronger penetration ability in many kinds of strata, moreover, its disturbance to stratum is slight, it is a kind of partly squeezed soil pile. If the distance between the driving pile and the center is smaller, the H steel pile can be used to replace other piles to prevent the ground fault caused by piling operation, such as lateral extrusion, uplift and so on.

Q: What is special steel?: Reinforcing bars for reinforced concreteIs a small type steel reinforced concrete. Including hot rolled round steel bar and prestressed concrete with reinforced concrete, thermal cold rolled steel. Steel reinforcement strip. In addition, also known as the other thread steel. Because the steel in rolling surface of rolled thread handle or reinforcement, steel reinforced concrete is in the construction industry reinforced. According to the material yield point and tensile strength, I, II, III and IV grade steel. The steel bars are used directly. The rebar, reinforced concrete to stress by heat treatment after heat treatment of high strength, but does not apply to steel welding and spot welding, reinforced by 40Si2Mn, 48Si2Mn, 45Si2Cr etc. steel after heat treatment is made, nominal diameter 6, 8.2, 10 mm. Cold rolled ribbed bar with Q215, Q235, 24MnTi steel, nominal diameter 4-12 mm. Steel after heat treatment should be rolled into plate, to heat treatment delivery.

Q: Can the section steel butt joint in the end?: If welding, it is mainly worried that the welding is not strong and the welding stress is too large. The wall thickness of the section steel is thin, and the butt welding itself is the most unreliable. So, in the joint lining board, fillet welded. Attention is paid to reducing stress in the process.

Q: What are the common types of profiled steel?: Complex section steel has: I-beam, channel steel, steel, elevator rail, steel sheet pile, and various kinds of agricultural machinery, machinery manufacturing and construction of special-shaped steel.Section steel according to production methods are: hot-rolled steel, cold-formed steel, welding, H steel, etc.

Q: How to distinguish cold formed section steel and hot rolled section steel?: Cold-formed steel is a product of various cross sections bent in cold form with steel plates or strips. Cold formed section steel is an economical light section steel, also called cold-formed steel section or cold bending section. Cold-formed steel is the main material for making light steel structures. It has various kinds of super thin and reasonable shapes and complicated sections which can not be produced by hot rolling. Compared with hot-rolled steel, in the same section area, turning radius can be increased by 50 ~ 60%, moment of inertia can be increased 0.5 ~ 3 times, so it can be more reasonable to use the strength of the material; and ordinary steel structure (from traditional I-beam, channel steel and angle steel and steel plate made of steel structure comparison) that can save steel by 30 ~ 50%.
