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 * 150 * 6.5 * 9 H steel is used as steel beam, span 6 meters, spacing 2 meters, laying steel plate, 15 cm soil
Q235 hot rolled H steel 300 x 150 x 6.5 x 9, weight per meter of 0.373KN. Wx=490000mm fand. Section modulus flexural strength design value of 215N/mm -. Uniform basic combination of load value Q, span 6m, the maximum bending moment design value of M=490000 * 215 =105350000N - M 105.35KN - m, q=105.35 * 8/6 L = 23.41KN/m.
Q:What does "welding H" steel set "vertical" and "corrective processing" mean?
Since the H steel web needs to be machined is 10 thick, it can be easily welded to the submerged welding machine, so there is no need to break the seamAfter blanking, use the crane to lift the plate to the erection machine one by one, and clamp. Start the set, set the machine, adjust the position of the three plates, and fix the spot weldingNote: the assembling machine is specially used to assemble the H steel machine, three plates, processing it can clamp type H steel H steel will start the machine, by the end of the assembling machine to roll to the other end, through assembling the machine when the door frame, can be used to adjust the assembling machine accurate three plate position, is a period of adjustment of rolling.After erection, the crane is welded to the welding platform and submerged arc weldingAfter welding, lift to straightening machine for straightening and correctingNote: the straightening effect correction principle: after welding flange may be not perpendicular to the web, using roller flat. Because H type steel may also be in the length direction is not straight, also can use the pressure roller is adjusted. The general steel processing plant of the straightening machine only in H flat slab steel width flat with length up straight. Straight up the length function of flame correction, flame correction, H steel with roasted curved, roasted red with water, due to thermal expansion and contraction, H type steel straight up. But it must have some experience to master the operation.
Q:Method for calculating weight of H steel
Sectional area=(H+2T =(TW)2bt 580×2×14)+2×280×12×14 = 144.64cm2
Q:How to distinguish between narrow flange and wide flange H section steel
The I-beam section is well pressed and resistant to pulling, but the section size is too narrow to resist torsion. H steel is vice versa, so both have advantages and disadvantages.
Q:What does H steel column H300*250*6*10-90 represent in steel structure?
Steel column: a column made of steel. Large and medium-sized industrial buildings (see map [CFST column construction plant "), long-span public buildings, high-rise buildings, homes, light work platform, the Zhanqiao and the support column, most of the steel column. The classified steel column can be divided into solid column and lattice column (Figure 1[steel column) in the form of cross section. Section form solid column with steel column section [the whole), is the most commonly used I-section; lattice column section is divided into two limbs or more limbs, the limbs with batten or batten plate contact (Figure 2b[] section steel column), when the load is larger than m, when the width of steel consumption is saved.
Q:Can the section steel butt joint on the end?
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. 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 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: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 are the specifications for H steel HW, HB, HN?
HN is H steel with a flange width ratio greater than or equal to 2; used mainly for beams and I-beam purposes, equivalent to HN.
Q:I would like to ask you to do the master of steel structure, steel H steel cost per ton, how many yuan? emergency
The H steel is priced at 850-1100 tons, with two rustproof primers and two alkyd finishesInstallation of steel structure costs between 350-450 tons per ton.I do steel structure budget, do not understand, you can ask me!
