Usage & Applications of Hot Rolled Structural Steel H Beam

Commercial building structure ;Pre-engineered buildings; Machinery support structure; Prefabricated structure; Medium scale bridges; Ship-building structure. etc.

Packaging & Delivery of Hot Rolled Structural Steel H Beam

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.

4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

5. Delivered by container or bulk vessel

Q:300*200h steel 7 meter span center load the most, can bearing 30 tons?
H section steel belongs to middle wing H section steel, can weigh 30 tons. 294*200*9*12 of the national standard. According to the specifications of the calculation, 10 meters span is large, or the cross section of the beam is a bit small, only the strong or the equivalent of roof purlin. Can not bear too much weight. Recommend the use of H type steel above 600*300*12*18. Below is the H type steel bearing calculation:RA=RB=P/2 Mc=Mmax=Pl/4 fc=fmax=Pl^3/48EI A= B=Pl^2/16EI symbol and theta theta P - Q - N; concentrated load, uniform load, N; R - bearing force, the direction of the action is positive, N; M - bending moment, the compression of the upper section, lower tension is positive, Nm; Q, the shear. The adjacent section of the torque in a clockwise direction is positive, N; F, deflection, downward displacement is positive, mm; angle theta, clockwise rotation as positive degrees; E - Gpa; I - elastic modulus, cross-sectional moment of inertia, m^4; L = x/. =x'/l, zeta, alpha beta gamma = a/l, =b/l, =c/l from two aspects
Q:In steel structures, what is the meaning of the "" between the two members of the H steel brace 2L 180*12,10?
Mainly divided into equilateral angle steel and equilateral angle steel two categories, the unequal angle can be divided into equilateral equilateral thick and unequal thickness two. Angle expressed side and edge thickness size. The current domestic steel specifications for 2 - 20 cm, to length number is the same number. Horn steel often have 2 - 7 different edge thickness. The actual size and the import side angle marked on both sides of the thickness and indicate the relevant standards. The general side of 12.5cm over the large angle, 12.5cm - 5cm for the medium angle, length below 5cm for small angle. The order of a steel export angle to use specification for steel, the carbon steel grades. The corresponding angle in addition to standard number, no specific composition and performance series. Puri steelThe fixed angle delivery length ruler, size two, domestic angle length range is 3 - 9m, 4 - 12M, 4 - 19m, 6 - four 19m range according to the different specifications. The Japanese steel section length range is 6 - 15m. unequal angle height according to length the edge of the equilateral angle steel wide to calculate.
Q:What's the difference between welded H - section steel and high frequency welded H - section steel and hot rolled H section steel?
Specification and material. When the hot-rolled H steel can fully replace welding of H steel, and the former than the latter to ensure quality. In general, in the structural design of high-rise buildings, should adopt the hot-rolled H steel, steel portal frame of light steel plant, selection of welding H steel with variable cross-section steel index is better, but the project cost can not save much, the reason is that the processing capacity of hot-rolled H steel is smaller, shorter duration, if the calculation of the comprehensive economic benefits (including the project put into use), play a decisive role in the period under the condition of optional hot-rolled H steel, but when the time limit for not strict or some image project, is in line with the principle of conservation of resources selection of welding H steel.
Q:Does the cross section of corrugated steel H have this section in PKPM?
At present, the Bowen of the corrugated web is a waveform determined by rigorous tests (which can be trapezoidal, sinusoidal, rectangular, discounted, etc.)
Q:How to control the welding deformation made of H steel
Features are as follows: wide flange and large lateral rigidity. Good bending resistance. The two surfaces of the flange are parallel to each other, so that the connection, processing and installation are simple. Compared with the welding drawing I-beam, the utility model has the advantages of low cost, high precision, little residual stress, no expensive welding materials and welding seam detection, and the cost of steel structure production is saved by about 30%. Under the same section load, the H steel structure of hot rolled 15%-20% steel is less than that of traditional steel structure. Compared with the concrete structure, the hot rolled H steel structure can increase the use area of 6%, while the structural weight is reduced by 20% and 30%, and the internal force of the structural design is reduced. The H steel can be processed into T steel, and the castellated beams can form various section forms to meet the demands of engineering design and manufacture. H steel is mainly used in engineering, plant, equipment, machinery and equipment, bridges, highways, houses, etc., with good mechanical and physical properties, firm and energy-saving and environmental protection. H steel is a kind of economical type section steel, widely used in industry, buildings, bridges, oil drilling platforms, according to the forecast in 2005 China's H steel demand of about 2 million 500 thousand tons, 5 million tons of demand in 2010, but the H steel of China's annual production capacity of 1 million 200 thousand tons, the market demand is very great.
Q:In the H steel frame, what is the connection between the secondary beams? Welding or high strength bolt connection?
Two can, anyway, there are connections, the strength can be guaranteed, it depends on the construction requirements and subsequent demolition requirements.
Q:What are the materials of H steel?
It consists of Q+ digital + quality grade symbol + deoxidization method symbol. The steel dubbed "Q", representing the yield point of steel, behind the digital representation of the yield point value, in units of MPa such as Q235 (s) said the yield point for carbon steel 235 MPa.
Q:How much is the weight of 200x200 H steel?
200*200 is the model, this model is divided into two specifications
Q:What's the quota for finished H - shaped steel sleeve?
In the installation of H steel, in addition to painting, that is, rust, units are 10m2, there is no security item. Landlord can not really apply: Civil Engineering - metal structural engineering - steel structure - steel wall (or other), and this is my personal opinion, for reference only.
Q:How is the weight of H steel calculated?
RA=RB=P/2 Mc=Mmax=Pl/4 fc=fmax=Pl^3/48EI A= B=Pl^2/16EI symbol and theta theta P - Q - N; concentrated load, uniform load, N; R - bearing force, the direction of the action is positive, N; M - bending moment, the compression of the upper section, lower tension is positive, Nm; Q, the shear. The adjacent section of the torque in a clockwise direction is positive, N; F, deflection, downward displacement is positive, mm; angle theta, clockwise rotation as positive degrees; E - Gpa; I - elastic modulus, cross-sectional moment of inertia, m^4; L = x/. =x'/l, zeta, alpha beta gamma = a/l, =b/l, =c/l from two aspects: first, from the beam considering shear stress second, the bending stress is considered. The maximum available shear strength of steel can be found from the steel sheet, T, Tmax=Q/Ib[BH^2/8-< (B-b), h^2>/8]: Tmax is the maximum shear strength. The maximum shear load of the beam can be calculated by replacing the available shear strength T. Q is the uniformly distributed load, and the section moment of inertia of I is B, which can be found in the steel table. (cm^4) the maximum width of the section of i-beam. B is the minimum width of I-beam section, h is the height of minimum width section of i-beam. H is the calculation of the height normal stress of the maximum width section of I-beam: Ysigma=M/W, M=, maximum bending moment = load, travel distance, W= flexural modulus. With the maximum allowable stress of Ysigma=, the maximum value of the load can be obtained.
