Product Description:

1. Structure of Steel Bar in Square Section description:

Steel bar in square section is a bar with square shaped cross-section. It is special case of equal sides. Before steel products are sold on the market, the steel must first be processed into more functional pieces. Raw steel cannot be of use while in its pure form, thus it has to be cast into shape. The freshly made steel, steel bar in square section is still in the form of a metal bar or rectangle. Small sizes of steel bar in square section are used in ship building.

 

2. Main Features of Steel Bar in Square Section:

• Grade: Q235

• Type: Mild carbon steel

• A quadrilateral with four equal sides and four right angles.

• Vibration: The stiffness and mass are chosen to prevent unacceptable vibrations, particularly in settings sensitive to vibrations, such as offices and libraries.

• Local yield: Caused by concentrated loads, such as at the beam's point of support.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

①What is the main material?

There are two types of Square Bar, one is hot rolled square bar and other one is cold drawn square bar. Our principal products is hot rolled square bar. We dedicate to products with material Q195 and Q235. We offer products with high quality and low price.

②How to inspect the quality?

We have a professional inspection group which belongs to our company. We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

③Is there any advantage about this kind of product?

Steel I beam bar IPE has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred.

Q:How to hollow square steel welding
Hollow square steel thin wall, should use special fixture precision counterparts, and retain the appropriate gap, in order to ensure the welding quality.
Q:100*100*2.5 square with 20 square meters of housing security light steel structure:
Sun room in the South or the north, need to reserve the burden of snow is not the same.
Q:How to make the steel arc
The steel made arc:Solid steel:1, bending machine bend into arc2, flame cutting off arc baking3, bending machine coil windingHollow square:The hollow square filled with sand again by the method of solid steel bending arc.
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
Wear zinc coating first, otherwise it is easy to form inclusion and other defects, and damage the strength of matrix.
Q:It can be used as the steel electrical equipment grounding
The steel can be used as grounding of electrical equipment, but because of the steel and the earth contact surface is relatively small, the grounding efficiency is not high, generally do not use. The steel pipe, angle steel and flat steel and other materials, the ratio of the circumference and area, has a larger contact area with the earth, in the same material case, get smaller grounding resistance, or in the same requirements of the grounding resistance, supplies are more economical than small, square steel.
Q:The difference between galvanized square and galvanized steel
The first dip galvanized pipe is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency. Or the cold formed hollow steel pipe prepared in advance will be galvanized by hot-dip galvanizing.
Q:Building with steel or steel plate?
Recommended use of channel ten, three meters span is not large, there will be no vibration problems! Do not use the bearing structure of square steel tube, the solid steel with the specifications of the cost is too high and the bending strength is hollow, not recommended.
Q:The difference between staircase truss square steel tube and angle steel
The tube, as the name suggests, it is a square shaped tube type, many kinds of material material can form a square body, it is medium in, what, in what place, most square to steel for the majority, for the structure of the tube, decorative tube, square building.Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process. Generally, the strip is disassembled, leveled, crimped and welded to form a round tube, then rolled from a tube into a square tube and cut to the required length. Usually 50 bags each.
Q:Twist steel (twisting steel) there is no standard?
Because the steel plate for standard parts, CAD drawing without draw, only need to mark the type and size of the bearing flat steel lattice steel plate and the direction of the steel grid plate, the specific use of what types of bar, can be specified by the user, if the platform is too large, can be discharged from the layout of steel grid plate manufacturers, general row layout is free.
Q:As for steel structure steel, how appropriate
Column: 200*200*8 rectangular tube as column, beam (main beam) is 300*300*12, secondary beam is 150*150*8@1500 evenly distributed. Roof beam 150*150*8 herringbone roof truss.
