Product Description:

1. Structure of Steel Flat Bar Chinese Standard Slit and Cut Form Description:

Steel flat bar Chinese standard slit and cut form is a beam with an I-shaped cross-section. The horizontal elements of the "I" are known as flanges, while the vertical element is termed the "web". Steel flat bar Chinese standard slit and cut form is usually made of structural steel and is used in construction and civil engineering. The steel flat bar Chinese standard slit and cut form resists shear forces, while the flanges resist most of the bending moment experienced by the beam. Steel flat bar Chinese standard slit and cut form theory shows that the I-shaped section is a very efficient form for carrying both bending and shears loads in the plane of the web.

 

2. Main Features of Steel Flat Bar Chinese Standard Slit and Cut Form:

• Grade: Q235

• Type: Mild carbon steel

• Deflection: The stiffness of the I-beam will be chosen to minimize deformation

• 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:

①Is this product same as W beam?

In the United States, the most commonly mentioned I-beam is the wide-flange (W) shape. These beams have flanges in which the planes are nearly parallel. Other I-beams include American Standard (designated S) shapes, in which flange surfaces are not parallel, and H-piles (designated HP), which are typically used as pile foundations. Wide-flange shapes are available in grade ASTM A992,[4] which has generally replaced the older ASTM grades A572 and A36.

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:Lightning protection grounding, what is called three surface welding?
When lap welding is adopted, the welding length is as follows:1, galvanized steel bar is not less than its width of 2 times, three surface welding. When the width of flat steel is different, the length of lap should be wide. Before laying, the flat steel should be adjusted straight, simmer, bend not to die, straight line should not be obvious bending, and should stand upright.2, galvanized round steel welding length of 6 times its diameter, and should be double-sided welding (when the diameter is not the same, the length of overlap in diameter should prevail).3, galvanized round steel and galvanized flat steel connection, its length is round steel diameter of 6 times.4, galvanized flat steel and galvanized steel pipe welding, in order to connect reliable, in addition to contact in itBoth sides of the site shall be welded, and the flat steel itself shall be bent in an arc to be welded with the steel pipe.
Q:What is the difference between 60X6 and 50X4 flat steel in grounding?
The contact resistance varies with the return current.
Q:How to grounding lightning protection grounding?
In the cupboard and a MEB box, distribution box shall be the total PE bus, building low voltage power distribution cabinet. The 2 main vertical bars in the column are used for grounding on the line when the potential is grounded, and then the hot galvanized flat steel is led to each LEB terminal box with 40*4. In the elevator shaft from the elevator pit 0.2 meters, and the elevator shaft end below each embedded 100*100*8 hot galvanized flat steel piece, flat steel and column 2 as the main vertical grounding line and welding.
Q:Earthing flat steel, width, overlap face, bolt, big country net
Usually 4 x 40 flat steel, you definitely won't use 6mm screw, but I use two 8mm screws to connect the strength of not less than 12mm of A.
Q:How can copper cables and flat steel be welded together?
As a thin strip of copper or copper brazing Hanbian flat, the flat copper or steel crimping brazed or welded to the ground flat strip. Not copper brazing, tin soldered or crimped copper braid, then copper tape terminal is connected to the flat.
Q:How to determine the application direction of steel grid plate
The length of a steel grid refers to the direction that carries the flat steel, and the width of the steel grid refers to the size measured in the direction along the cross bar (usually the cross bar with a twist Jiao Fanggang)
Q:How large is the flat steel used for equipotential grounding?
According to the GB 50054-2011 3.2.15 6# responses (table 3.2.15), the distribution system of equipotential bonding conductor may be 25mm2 copper; when the 1/2PE line section of not less than the case, must use 25mm2 copper (or the equivalent capacity of aluminum or steel); according to the GB 50057-2010 5.1.2 (table 5.1.2), lightning protection system equipotential bonding conductors with 16mm2 copper, can meet the minimum section of all the connecting parts of the requirements of lightning protection device. Therefore, "lightning protection system equipotential" equipotential bonding conductor specification is greater than "distribution system equipotential" equipotential connection conductor is not necessarily established.
Q:Galvanized flat steel how much is one meter?
The price of galvanized flat steel is about 6200, so the price is 40 * 4 * 0.00785 * 1.06 * 6.2=8.3 yuan per meterGalvanized pipe price is about 6500, DN25:2.57 * 6.5=16.7 yuan / meter, DN32:3.32 * 6.5=21.58 yuan / meterAngle steel price 5000, 4# angle steel: 2.422 * 5=12.1 yuan / meter
Q:Can lightning protection earthing steel bar be directly welded with thread steel?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:The distinction between flat steel and steel strip
Cyanide is a chemical heat treatment, before the process is highly toxic, serious environmental pollution, the latest process can meet the requirements of environmental regulations, and if not necessary, the use of nitrogen treatment or carbonitriding better.
