Usage & Applications of High Quality Hot Rolled Q235, SS400 or Equivalent Steel H-Beam for Construction

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


Packaging & Delivery of High Quality Hot Rolled Q235, SS400 or Equivalent Steel H-Beam for Construction

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:What is the height of the four fillet welds in H steel submerged arc welding, such as H600*300*6*12?
The plate thickness is 6 and 12 respectively, and the fillet weld value is the same as the thickness of the thin plate (when the design does not require)
Q:In the steel structure, the semifinished product H steel column, whether also sets the manufacture quota?
Bored pile: drilled into the depth of rock (the municipal and highway quota projects contain a great gap in content)
Q:What does H steel.R represent?
The latest H steel specifications range wide, medium and narrow flange H steel size, H- height, B- width, t1- web thickness, t2- flange thickness, r- rounded radius
Q:Light thin-walled H steel, in addition to welding, is there any hot rolling?
Domestic H steel production line is about 10, mainly from Germany to introduce production lines.
Q:Which is better, I-beam or HN steel?
Mainly to see what you mean, I-beam and HN steel beams of what size, or look at section size. Generally I-beam is stronger
Q:What does "H400*250*8*12" mean in steel structures?
A direct consequence of low industrial concentration is caused by excessive competition, in 2005, the average profit of 5% steel enterprises, in addition, steel tube truss and complicated structure, difficult construction of landmark projects to higher profit margins, as building light steel portal frame, due to intense competition, the profit space is generally low, so only there are some enterprises in order to steal frugal material bidding, so only the sensation of three-dimensional "white paper". But the good news is the processing capacity of 13 million 510 thousand tons of steel structure steel structure association in 2005 statistics, the processing capacity of the top five steel enterprises has more than 1 million tons, the annual top ten enterprises the basic processing capacity in more than 100 thousand tons.
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: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.
Q:H steel column calculationHow do you calculate the amount? And what are the steps and formulas for this calculation?
H steel is welded; HWHMHN is the hot rolled HW H steel is the height and width of flange is basically the same; mainly used for reinforced concrete frame column steel column, also known as rigid steel column; in steel structure is mainly used for HM H type steel column height and wing
