Packaging & Delivery of Hot Rolled H-Beam Steel for Building Structures

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

* If you would like to get our price, please inform us the size, standard/material and quantity. Thank you very much for your attention

Function Structure

Light H-beam has been widely applied as building material and has a very good market prospect. High frequency H-beam welding is a new technology for H-beam welding with the advantages of energy-saving, high efficiency and convenient operation etc.

H-beam welding equipment adopts two sets 300kW or 600kW solid state high frequency welder with exactly the same model. One welds web plate and upper flange plate, the other welds web plate and lower flange plate. The welding mode is contact welding. Solid state high frequency welder adopts AC-DC-AC frequency conversion structure. The rectifier adopts 3-phase thyristor. The inverter adopts high voltage large power MOSFET to form full bridge resonance inversion. Inverter output adopts high efficiency ferrite matching transformer to finish power combination, impedance matching and electrical isolation. Resonance tank circuit adopts two sides serial resonance.

The complete unit of equipment is composed of switchgear rectifying cabinet, inverter output cabinet, contact head mechanism, circulation soft water cooling system, console and 3-D positioning table.

Technical Features

      Ø Perfect structure design

1.Independent design of switchgear rectifying cabinet and inverter output cabinet, connected by soft cable, which is convenient for layout at users site.

2.Power combination of the inverter bridge is accomplished by the way of power unit superposition. Each MOSFET power unit is designed to be 100kW and slideway drawer structure, which is convenient for installation and repair.

3.3-D positioning table is adopted for both of the two sets contact type welder. Contact head adopts pressure control, which has a good synchronism and consistency.

4.High standard electromagnetism compatibility design, electromagnetism radiation meets national standard.

5.Closed cabinet design, meeting rigor environmental requirements on site.


Ø Full-digital Synchronization Control System

1. 3-phase rectifier adopts high cost performance MCU controlling to realize precise synchronism trigger with high control precision and small grid-side non characteristic harmonic.

2. Resonant inverter adopts CPLD to form full-digital control system that is characterized by their automatic constant angle, high phase-lock precise and wide scope of phase-lock.

3. The two sets solid state high frequency welder has the function of synchronization control with the features of stable working and small interference.

4.The welder has perfect protection function with reliable working and low failure rate.


Ø HMI and fault diagnosis system

1. Adopt PLC and touch screen to form perfect HMI system.

2. Realize integrated automatic control of welder system.

3. Fault display and diagnosis system.

Q:H steel compared with ordinary steel in the end what are the advantages and disadvantages?
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 is easy to connect with high strength bolts and other components. Its size constitutes a reasonable series, complete model, easy to design and use. (in addition to crane girders)
Q:Are all the steel girders H?
When the width is large or the load is relatively large, besides the H type steel beam, it is more common to use the box girder.
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?
There are two kinds of hot rolling and welding. The hot-rolled one is 12M, which is finished steel. The welding is made of heavy plate welding and there is no length limit
Q:What's the difference between hot rolled H steel and welded H? Is it the same weight?
The product has high precision and good surface quality. Because of the high precision and good surface quality of the steel plate, the accuracy of the H after welding is high and the surface quality is good. (used for welding H steel plate) the thickness deviation is generally a few hundredths of a millimeter to zero a few millimeters, and the thickness deviation of hot rolled H steel is a few tenths of mm to 1 mm, is nearly 10 times.
Q:How can the steel posts of different types of H steel be butted?
The welded joint, flange should be used in single V groove plate with full penetration weld, the web should use the K shaped groove double partial penetration weld, the opposite is not clear; the design requirements of Web full penetration, such as the web thickness is less than 20mm, should adopt single V groove welding (plus plate figure 4.6.2-1 E), such as the web thickness is greater than 20mm, should adopt the K groove, double negative root cleaning after welding
Q:I would like to ask you to do the master of steel structure, steel H steel cost per ton, how many yuan? emergency
Installation of steel structure costs between 350-450 tons per ton.It is not enough, labor costs rise, steel installation fee of around 450, Chongqing installation fee of around 550The production fee is 800-1000, including two primers.I am a steel construction unit, 10 years of operation. Don't ask me. Give me the best answer.
Q:What are the materials of H steel?
The main material of H steel is Q235B, Q345B and so on.
Q:Calculation method of H steel area
Web section = plate thickness * widthWing plate area = plate thickness * width *2 (2 wing plates)H sectional area = web cross section + wing section area
Q:H Elastic modulus of section steel
The elastic modulus of steel is 2.1 * 10^7N/cm L.
