Product Description:

1. Structure of Square Bars with Firm Sides 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 Square Bars with Firm Sides:

• 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:Why is a point of penetration of 2 square steel welding
Now the steel mostly under poor material, 2 - 0 1 - 8 square the actual thickness is good, which is on the one hand, choose another current must be small.
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:The steel and wood preservative in the flower is how to connect
Or with the aid of angle steel, angle steel and steel welding, wood preservative and angle connected by bolts.
Q:Building height is 5m, the main dry hanging stone square spacing value should be how much better?
Really not assured, spend some money to let people count, but as long as there is no special structure or shape, then you do not have to spend the wrong money.
Q:You need to light steel keel wall square steel
Lightweight partition walls are usually made of lightweight bricks (aerated concrete or hollow bricks) made of cement mortar. The utility model has the advantages of good sound insulation and good fire prevention performance. (relative) but it is troublesome to thread the pipe in the wall. And wet operation, long duration.
Q:The joiner board is fixed on the square on how
Self tapping nail is generally refers to the thread of the tooth is self tapping, so that the role of self drilling, do not need to use the nut together. The screw head has a lot of classification, there are six outer corners of the head, pan head, with countersunk head, internal angle of six head. An umbrella head, padded head, etc. The tail is usually pointed. Self tapping.
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:What is the use of square steel keel or welding steel canopy
Canvas awning: crank arm type retractable awning is in a separate structure, relatively safe, without the square tube, no paint spray, arm firmly and focus on both sides of the steel plate bracket, if the canopy length of more than 5m, the increase of direct arm assembly and focus on the middle support, on both sides of the iron with expansion screws are mounted directly on the solid wall, or welded firmly in indirect metal frame, the installation conditions need to pick out the roof, or rain gear plate, telescopic arm type awning is a retractable awning can be arbitrarily different stretching length, wind speed Aluminum Alloy bracket can withstand 50KM/ph. Maximum size of up to 18 meters wide, stretching length of up to 1.5 - 3.5 meters, the adjustment is divided into manual, electric, remote control and wind control, light control, rain control and many other ways for you to choose. Features: the main feature of this tent is cheap and practical. The sunshade cloth: generally equipped with ordinary canopy canvas, suitable for ordinary shops and small ordinary city.
Q:Twist steel (twisting steel) there is no standard?
Lattice steel plate steel bar is also called twist, the steel twisted shape, so only when the square size annotation annotation, common general specifications for 8*8mm, 6*6mm, 5*5mm, in the standard steel plate, the bar is defined as fixed on the bearing flat steel, round steel, square steel twisted or flat, that is say, don't necessarily use twisted steel (steel twist) but hot dip galvanized steel grid plate used in the steel industry used torsion, stainless steel using round steel, and make use of flat bar made of steel plate. We called steel grid plate or pressure locking steel plate, steel plate of GB also do this cross sectional area:: twisted steel, round steel bar with flat steel, its cross-sectional area of not less than 20 mm.
Q:How can we see is galvanized steel or wood
There is a difference in the quality of classification and can be processed into cold and hot dip galvanized pipe, galvanized pipe, galvanized pipe and galvanized belt can not be made, because of its wall thickness is thin, so the price will take the price dip galvanized pipe is much higher than galvanized pipe.
