Usage/Applications of Q235 Steel Flat Bar
Widely used for construction, Machinery manufacturing, Iron tower steel structure, Shipbuilding; Steel grating, Staircase, Bridge, Viaduct, Railway spare parts, Boilers making etc.
Production Flow of Q235 Steel Flat Bar
The steel flat bar is made through three processes:
1.Feeding the material: Feeding the row material (the steel plate) to Slitting Line.
2.Slitting:The steel plate would be slitted into expected width by lengthways cutter.
3. Leveled and cutting: The plat bar would be ground into level by the grinder and then cut into required length.
Packaging & Delivery of Q235 Steel Flat Bar
Packaging Details: The Steel Flat Bars are packed in bundles and loaded in 20 feet/40 feet container, or shipped by bulk cargo ,also we can do as customer's requirements.
Delivery Details:30~45 days upon the receipt of buyer payment by T.T. or L/C.
- Q: What does "M" mean?
- Section steel is a strip steel with definite section shape and size. It is one of the four big kinds of steel (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel).
- Q: Does the profile include H?
- Profiles include section H steelThe online quote H steel and profiles in the angle of groove separate quotation, mainly because H steel has great use compared with the other, and the demand is relatively more, but in some cases, and H type steel I-beam can also substitute for each other.
- Q: What does "BH" mean?
- BH is welded to H just, and RH is hot rolled H steel.
- Q: Elastic modulus of section steel
- The elastic modulus of steel is 2.1 * 10^7N/cm L.
- Q: What kind of steel is used in steel columns?
- Compared with other steel piles, steel pipe piles have their own advantages in many aspects, such as long joint welding, single pile bearing capacity, bending rigidity and penetration ability.
- Q: What is special steel?
- Military materialsOther varieties are mainly some special quality profiles. Including hollow steel, oxygen bottles, industrial pure iron, hot rolling, cold heading steel easy to cut steel, D60, S/5A, F18, F11 etc., behind several are. High quality steel is not large, medium and small, round and Fang Gang divided into groups according to specifications from, such as 8-10mm, 11-15mm, 18-20mm, 205-245mm. flat area by large, medium and small flat. Six angle distance is not grouped. But the quality of steel group distance is no substitute for detailed specifications, in the document should be filled concrete specifications. Quality profile specification is simple, the vast majority of round steel. In addition, flat steel, and Fang Gang six chest steel, hollow steel, shaped and so on hot rolling (forging) size deviation of high-quality steel, Fang Gang, the six angle of the ordinary high accuracy and precision of two. And has a more precise cold drawn profile surface size and smooth surface polishing, polishing, but also some After polishing or round processing. The polished surface is exquisite, called steel. High quality profiles are rarely used, mostly through the use of the unit for further processing and after heat treatment, therefore, in addition to chemical composition, but also to ensure the mechanical properties after heat treatment.
- Q: Can the section steel butt joint in 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 common types of profiled steel?
- Section steel is divided into two types: simple section steel and complex section steel.Simple section steel: steel, wire rod, square steel, flat steel, six angle steel, triangular, elliptical steel, steel arch steel, etc..
- Q: How to distinguish cold formed section steel and hot rolled section steel?
- Cold-formed steel is a product of various cross sections bent in cold form with steel plates or strips. Cold formed section steel is an economical light section steel, also called cold-formed steel section or cold bending section. Cold-formed steel is the main material for making light steel structures. It has various kinds of super thin and reasonable shapes and complicated sections which can not be produced by hot rolling. Compared with hot-rolled steel, in the same section area, turning radius can be increased by 50 ~ 60%, moment of inertia can be increased 0.5 ~ 3 times, so it can be more reasonable to use the strength of the material; and ordinary steel structure (from traditional I-beam, channel steel and angle steel and steel plate made of steel structure comparison) that can save steel by 30 ~ 50%.
