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:H steel compared with ordinary steel in the end what are the advantages and disadvantages?
The flanges of H steel are all of equal thickness, there is a rolling cross section, and there is a combined section composed of 3 plates welded together. I-beam is a rolling cross section, due to poor production process, flange within the edge of the 1:10 slope. H type steel rolling is different from ordinary I-beam with only one set of horizontal roll, because of its wide flange and no inclination (or inclination is to be very small), a group of vertical roll and roll, therefore, the rolling process and equipment than the conventional mill complex. The maximum rolled H steel produced in China can be 800mm high and can only be welded composite sections.
Q:Why is it that the steel pile is low in cost and easy to construct, and it can be changed when there is an obstacle
This is the specification of hot-rolled narrow flange section steel.Cross section 300, flange width 150, web thickness 6.5, flange thickness 9.
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:In steel structures, what is the meaning of the "" between the two members of the H steel brace 2L 180*12,10?
Angle called angle, the steel strip is perpendicular to each other on both sides into angular. Equilateral angle steel and unequal angle points. An equal angle two edge width is equal. The specification is expressed by edge width * width * mm thick edge edge. Such as "/ 30 x 30 x 3", that is an equal angle the width is 30 mm, 3 mm thick. Also available models that model is the edge width cm, such as angle 3#. models do not represent the same type in different edge thickness dimensions, and thus in the contract and other documents will be the angle edge width, edge thick size fill in complete, avoid separately represented by models hot rolled edge angle specifications for 2#-20#.
Q:H how long is the length of the steel section?
Hot rolled H steel is usually fixed length of 12 meters or less, if it is welded H steel can reach 20 meters or longer, hot-rolled H steel is too long, transportation is not convenient
Q:How should the steel H columns in the middle of the gable be placed?
The wind column force calculation model, column base embedded in the top surface of the foundation, the upper pillar is flexible hinge, see is shown in the picture. Flexible hinge is a horizontal tie truss support, the node structure of the vertical horizontal is unconstrained, elastic constraint
Q:What does H steel.R represent?
It should mean the rounded radius of H steel.
Q:Light thin-walled H steel, in addition to welding, is there any hot rolling?
Is the big Hebei Jinxi, Shandong sunshine, other mills some specifications such as Tangshan Shengda, Anshan Bao steel smelting, etc.
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:What are the uses of I-beam and H steel?
H section steel is a kind of economical and economical cutting surface profile (other cold bending thin wall steel, pressed steel plate, etc.). Because of the reasonable cross-section shape, they can make steel more effective and improve the bearing capacity. Unlike ordinary I-beam, the flange of H steel is widened, and the inner and outer surfaces are usually parallel, so that it can be easily connected by high strength spiral bolts and other components. Its size constitutes a reasonable series, complete model, easy to design and use.
