Product Description:

1. Structure of Steel Long Product of Square Section Bar Description:

Steel long product of square section bar 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 long product of square section bar is still in the form of a metal bar or rectangle. Small sizes of steel long product of square section bar are used in ship building.


2. Main Features of Steel Long Product of Square Section Bar:

• 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. How to guarantee the quality of the products?We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;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
Welding welding of thin-walled square steel, should be very careful when welding, arc welding technique should be used to pick, watch live pool, found that the weld pool collapsing must be timely arc.
Q:The steel structure material can do
Yes, both sizes can be done. The main check
Q:The water was poured into the square on how to prevent rust after treatment
The steel should try to avoid the rain, if you have been caught in the rain, according to the properties of the steel is not the method to wipe, such as high hardness steel wire brush, cloth, cotton and other materials of low hardness.
Q:Why is a point of penetration of 2 square steel welding
Electrode selection 2, 0J422, welding current about 80, if conditions permit, you can use carbon dioxide welding, welding process is very good grasp.
Q:The steel structure material can do?
First of all, will cause the waste of steel using square large section case, increase the weight of the structure, which is contrary to the steel structure of light weight advantages, small cross section from the processing, production process, the use of steel will be more, in addition to the special requirements, do not recommend the use of square steel.
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:The steel structure of 40*80 steel, it is tempered glass top. The steel internal fight foaming agent. But there is rust in the inner surface. Will it affect the safety? How to deal with
This shows that the coating has entered the water or corrosive medium, and should not have much to do with the wall of the square pipe. Reasons for coating failure:1, the grass-roots treatment is not good. Steel structure shall be sand blasted.2, the selected paint should be better performance of anti-corrosion coatings, rather than ordinary alcohols and acids.3, must have primer, finish matching.4, coating thickness must be more than 200 microns in order to effectively prevent water penetration. The paint sprayed from you is likely to be caused by too much coating. Unless you spray it with airless spraying.
Q:How to fix the steel Aluminum Alloy
With self tapping screws, that is, with drill screws, building materials market can buy. Electric screwdriver, you can put the wood board through self tapping screws into the steel. But attention should be paid to buy the self tapping screw length, short patch does not live too long into the square, too much is not good.
Q:4*4 steel welding frame tank do strong?
Electronic tube bracket fixed on a shelf, and then put the top shelf in the aquarium, pay attention to water, heat, can be a good solution, the lamp holder can buy ready-made, bought a switch, wires, plugs, insulating tape back to assemble their own good is.
Q:How much is the thick wall hollow square 30*30
Hollow square 30*30 wall thickness is 5mm.
