Q: What does "M" mean?: Section steel is a strip steel with definite section shape and size. It is one of the four big kinds of steel (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel).

Q: Does the profile include H?: Another reason is that H steel is made late in our country, so people are used to distinguish it from other shapes. But in the strict sense, H steel is a kind of section bar.

Q: What does "BH" mean?: Section steel is a strip steel with definite section shape and size. It is one of the four big kinds of steel (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). 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: Elastic modulus of section steel: Generally speaking, the elastic body exerts an external function, and the elasticity experiences the change of the shape (called strain). The general definition of the elastic modulus is that the stress is divided by the strain. When the material is in the elastic deformation stage, its stress and strain should be changed into a positive proportion (that is to say, according to Hooke's law), and the coefficient of proportionality is called the elastic modulus.

Q: What kind of steel is used in steel columns?: The steel sheet pile has various forms, and the sides of the steel sheet and the joint groove are different in shape. The second plate, after the first one is in place, takes the front sheet of the sheet pile and the side notch is used as the driving point. As a result, a plurality of sheet piles may form relatively complete sheet pile walls along the coast (or bank of the river). In addition, a group of steel sheet piles can be used for temporary retaining protection when the foundation pit is excavated or excavated.

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?: Docking is usually available.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.Bolt connection also requires lining plate, pay attention to bolt size, quantity and spacing. To calculate whether thin-walled steel itself will be crushing, the solution is solder paste board, and bolt holes.In short, the principle is that the strength of the butt joint is not weaker than that of other parts, and there is no greater stress.

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?: Hot rolled steel is a kind of steel with various geometrical cross section formed by heating billet. According to the different angles can be divided into flat steel, steel section, steel and I-shaped steel and hot-rolled L steel; steel according to the different section shape, divided into simple and complex section or section section and section three steel cycle:The characteristics of the simple section are the cross section, any point on the periphery as a tangent, generally not cross section, such as round steel, square steel, six angle steel, flat steel, triangular steel, arch steel and elliptical steel.Complex sections include angle steel, I-beam, channel steel, T steel, H steel, Z steel, rail, steel plate pile, window frame steel and other miscellaneous section steel;The periodic section shape and dimension along the length direction of the steel section changing periodically, such as rebar, axle and steel ploughshare.
