Packaging & Delivery of Carbon Steel Flat Bar

Packaging Details: The Steel Flat Bars are packed in bundles and loaded in 20 feet/40 feet container, or shipped by bulk cargo ,also we can do as customer's requirements.

Delivery Details:30~45 days upon the receipt of buyer payment by T.T. or L/C.

 

Production Flow of Carbon Steel Flat Bar

The Carbon Steel Flat Bar is made through three processes:

1.Feeding the material: Feeding the row material (the steel plate) to Slitting Line.

2.Slitting:The steel plate would be slitted into expected width by lengthways cutter.

3. Leveled and cutting: The plat bar would be ground into level by the grinder and then cut into required length.

 

FAQ:

Q1: What makes stainless steel stainless?

A1: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q2: Can stainless steel rust?

A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:The total floor distribution along the wall surface 40x4 galvanized flat steel, flat paint is painted yellow mark or brush a straight chute
Fire retardant anti-corrosion coating, waterproof and anti-corrosion, and insulation effect is good, can be painted on any material, anti high temperature insulation shielding current through, corona discharge point phenomenon. Good insulation is the most basic and reliable means to ensure the safe operation of electrical equipment and lines, and to prevent the occurrence of electric shock accidents. As for what brush Road, this seems to have no mandatory requirements. Hope to adopt!
Q:Galvanized steel flat welding occurs after the material itself crack.
Cold crack: a cold crack is a weld crack that occurs when the joint is cooled to a lower temperature. The causes are the quenching tendency, the residual stress, the diffusion hydrogen content of the weld metal and the heat affected zone.
Q:Is there a requirement for the ground resistance of the field motor? Is it good to use ground flat steel or ground wire?
The enclosure is grounded and the ground wire is the same, and the ground wire requirement is no more than 4 ohms. Generally, the motor shell can be connected to zero. There is no need to ground. In the power system, earthing and zeroing can not be mixed.
Q:8 what is the flat density?
8 mm flat steel density is about 7.85 g / cm.
Q:The difference between galvanized round bar and galvanized flat steel
It has been widely used in the fields of hardware, construction, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, space, etc.. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.
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:How can copper clad steel ground electrode and galvanized flat steel be welded?
If you want it to work well, use heat release welding, and if you take into account the cost budget, there are connectors, connectors that are just mechanical connections
Q:What is the difference between steel band and steel ring? The steel strip is flat steel and the steel ring is made of steel. Am I right?
A steel strip is also a coil, usually a narrow strip, also known as a steel strip. The volume is relatively wide. In addition, flat steel is usually hot-rolled out of long strip steel, fixed length 5 and 5.5,6 meters range, steel coil is Kaiping Chang 12501500, length 2.5 meters, 4 meters, 6 meters, ranging from steel plate
Q:What is the weight calculation formula for galvanized flat steel and galvanized steel angles?
(1) grounding wire is generally made of 40mm * 4mm galvanized flat steel.(2) galvanized steel or angle steel for earthing body. The diameter of the steel pipe is 50mm, the wall thickness of the pipe is not less than 3.5mm, and the length is 2 to 3m. Angle iron shall be 50mm * 50mm * 5mm.(3) the top of the grounding body from the ground 0.5 ~ 0.8m, in order to avoid thawing soil, soil resistivity or steel angle as the root number of the ground around the body and decide, generally not less than two, each spacing is 3 ~ 5m(4) the distance between the grounding body and the building is over 1.5m, and the distance between the grounding rod and the independent lightning rod is greater than 3m.(5) the connection of grounding wire and earthing body shall be done by lap welding.
Q:What do the numbers in the steel HN346*174*6*9 refer to?
Small steel: small steel, middle, round, square, flat steel processing and use, similar to large steel, small diameter round steel is often used as building steel.
