Usage/Applications of Mild Steel Flat Bar

Widely used for construction, Machinery manufacturing, Iron tower steel structure, Shipbuilding; Steel grating, Staircase, Bridge, Viaduct, Railway spare parts, Boilers making etc.

Packaging & Delivery of Mild Steel Flat Bar

Packaging Details: The Mild 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 Mild Steel Flat Bar

The Mild 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

Q:The steel, steel and flat steel, round steel bar and what is the difference?
There is not much difference between round bar and steel bar, but the diameter range should be different. Can you hold it with hand?Inside the details of the difference, you can go to the tool book to see.
Q:Galvanized flat steel how much is one meter?
Formula of flat steel: width * thickness * 0.00785 (kg/m), zinc coating weight: 1.06Galvanized pipe formula: (outer diameter wall thickness) * wall thickness * 0.02466 * 1.06, DN25 galvanized pipe outer diameter 33.5, GB thickness 3.25, weight: 2.57kg/m, DN32, outer diameter 42.3, wall thickness 3.25, weight: 3.32kg/m. DN stands for nominal caliber.Angle formula (approximate): edge width * thickness * 0.015, 4# angle iron weight 2.422kg/m
Q:Is there a requirement for the ground resistance of the field motor? Is it good to use ground flat steel or ground wire?
I wonder if you mean the resistance of the motor winding to the shell, or the resistance of the shell to the ground, and the resistance of the winding to the outer shell is more than 500 billion euro.
Q:Are there any differences between flat iron and flat steel?
The steel and iron are carried out using redox reaction, but there is a great difference in the response object: iron is iron reduced, while steel is the excess carbon in pig iron and other impurities in the actual operation, so the two links are different.There are three main ways to make steel: converter, electric furnace and peace furnace. Among them, the converter steelmaking method is more common. We do not need to remember its specific operations (but only to lead to understanding), but attention should be paid to reactions such as ferric oxide, removal of magazines and deoxygenation. A large amount of brown vapor is produced during steelmaking, consisting of iron oxides, dust particles, and high concentrations of carbon monoxide, which must be purified.
Q:What is the difference between 60X6 and 50X4 flat steel in grounding?
The contact resistance varies with the return current.
Q:What line is the LEB line, please? Is it wire or flat steel or galvanized round bar?
Equipotential bonding is the connection of metal and conductive parts exposed to electric devices and other devices in the building, artificial or natural grounding bodies, in order to reduce the potential difference, called equipotential bonding. Equipotential bonding is divided into total equipotential bonding, local equipotential bonding and auxiliary equipotential bonding.
Q:Building poles, outdoor flat steel, the deeper the buried depth, the better?
Building poles, outdoor flat steel, buried depth is not as deep as possible. According to the standard requirements, the level of the embedded depth is not less than 0.6 meters.
Q:What's the difference between hot rolled flat steel and flat rolling tool flat steel?
Hot rolled flat steel rolling tools - tool steel, commonly used for measuring and cutting tools with what. Material is tool steel, such as carbon tool steel (T8, T10), alloy tool steel (Cr12MoV), high-speed steel, etc..
Q:Where is the use of flat steel in electrical use?
The main use of galvanized grounding in building electric device, equipotential connection, such as transformer neutral point grounding, power distribution cabinet repeatedly grounding of electrical equipment and protective metal pipeline grounding and equipotential connection of buildings, building the underground lightning belt (that is the root of a plurality of buried steel the grounding electrode connected), building lightning deflectors and high-rise building equalizing ring (without using the building structure reinforcement), cable bracket (laminated cable trench or substation room or subway) or slot (or tray tray) metal grounding connection, welding and in the use of bolt connection, look to determine the design requirements and conditions, generally buried (wall) welding used in concrete or concealed, must be at least three surface welding, welding (two flat lap length Larger than the width of flat steel 2.2-2.5 times, round steel and flat steel lap length is greater than round steel 6-8 times, welding mouth does not allow slag, meat and remove welding slag, welding finished, in addition to concrete, do anti-corrosion, rust prevention;
Q:The difference between use and performance of hot rolled flat steel and longitudinally cut flat steel is discussed
Its manufacturing process determines the poor dimensional accuracy of hot-rolled flat steel.Vertical shearing flat steel (fine shearing flat steel strip):The raw material board is produced by a larger factory, the raw material source is controllable, the material can be basically guaranteed, and the mechanical performance can basically meet the relevant GB standards.The dimension of vertical shear flat steel is relatively high.
