Product Description:

1. Structure of Steel Square Billet Description:

Square bars with firm sides 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, square bars with firm sides is still in the form of a metal bar or rectangle. Small sizes of square bars with firm sides are used in ship building.

 

2. Main Features of Steel Square Billet:

• 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:What is the role of square toilet
The steel is generally used in light steel structure mostly, such as steel roof, residential skeletonCommonly used structural steel according to the specifications of size for different purposes, decorative elements, assembled truss, supporting member, grid and other small pipe truss, large steel plant can be used for concrete filled steel tube truss steel column, a large stadium; another major use is round process pipeline, but in general the material and anticorrosion special requirements.
Q:How to connect with steel purlin roof
The steel wall frame generally refers to the glass curtain wall of the airport, or the windbreak wall of the coal yard. It is the wall structure, and the former two are the roof structure.
Q:How to make the steel arc
If reinforced by 1. fold 2. arc bending machine flame cutting machine 4. fold 3. baking arc building arc roll can be solid steel grip bending machine processing.
Q:The difference between square and square.
Square refers to the use of a square billet material rolled out, or by round steel after cold drawing process, the material out of the square. Formula weight: side length of square theory * * 0.00785=kg/m.
Q:How the steel columns and I-beam steel structure connection?
The characteristics of the steel is of high strength, light weight, good integral rigidity, deformation ability, it is used in the construction of large span and super high and super heavy buildings especially suitable; homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness that can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high degree of mechanization; the processing of high precision, high efficiency, good sealing performance, so it can be used in the construction of tank, tank and transformer etc..
Q:Reinforced concrete and steel stairs to do the stairs which is better
Square is a square cross section of steel bars (square steel), not rectangular steel tube, can not do the stairs.
Q:How much is the thick wall hollow square 30*30
Hollow square 30*30 wall thickness is 5mm.
Q:Hot dip galvanized steel can be welded
Hot dip galvanized steel can be welded. The main methods of welding are as follows:1. manual arc welding. Remove the welding seam and the nearby zinc coating before welding. The welding rod can choose J421/J422/J423 and E5001/E5003 welding rod according to different requirements;2. gas metal arc welding. CO2 gas shielded welding can be used.3. argon arc welding.4. resistance welding.
Q:The difference between cold and hot galvanized steel hollow where
Cold rolling process is: the strip through the mold, pipeline bending forming, and then through the automatic welding, the welding joints, and then polished, galvanized, also called seamed tube.
Q:Square steel and C steel which is better?
24 square meters, not ordinary sandwich panels, the proposed use of square tubes, want to secure a little, then use C steel, depending on how thick material and decided to require more detailed information, you can find me, I do color steel sandwich panels
