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:What is the quota for the flat steel used in the lightning belt -40*4?
Set the lightning protection net, the main material is -40*4 galvanized flat steel, if you are using 12 yuan quota steel, also set the lightning protection network quota, but the material is converted into flats on the line,But now the lightning belt is usually 12 yuan steel,
Q:The difference between galvanized round bar and galvanized flat steel
Galvanized flat steel can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.Flat steel adopts negative deviation rolling, but according to actual weight delivery, the utilization ratio of steel plate increased by -5 percentage points. Flat can according to user needs, set the thickness, width and length of production, for the user to reduce the cut and save processes, reducing labor, material consumption, but also reduce the loss of raw materials processing, time saving, material saving. Products have been specialized in steel structure manufacturing, machinery manufacturing, automotive industry, mining machinery, lifting machinery and other industrial materials.
Q:What about the installation height of the socket and the height of the ground flat steel?
If the construction unit, design institute and contact Party A drawings or design change
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:Hot dip galvanized flat steel specification 40X4, 60X6 meaning?
Section size of flat steel * width * thickness. Unit: mm.
Q:The difference between use and performance of hot rolled flat steel and longitudinally cut flat steel is discussed
Hot rolled flat steel (hot rolled flat steel strip):Mostly produced by small factories, the raw material sources are disordered and the material can not be guaranteed. Therefore, the mechanical properties of hot-rolled flat steel are greatly different. Hardness, tensile strength, elongation, weldability are often unpredictable.
Q:What is flat steel for?
Hot rolled flat steel is a general purpose rectangular cross section strip. The specifications are expressed in millimeters of thickness * width, flat steel can be finished steel, used for components, ladders, bridges and fences, etc.. Flat steel can also be used to weld rigid steel and billets and slabs of laminated sheets. (material: Q215, Q235), the implementation standard: GB704 - 1988 instead of GB704 - 83, this standard applies to the thickness of 3~60mm, width of 10~200mm, cross section of rectangular hot rolled flat steel for general use. Delivery status: flat steel delivered by straight line. Measurement: flat length and length of flat steel, according to the theoretical weight of delivery.
Q:How is three grade steel connected to ground flat steel?
Steel bars welded with flat bars should be of little size, 12mm bar, and if you are not sure, you can use a section of HRB335 over.
Q:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Specification requirement is 25*4 or 40*4 hot galvanized flat steel, said the family specification is also very reasonable, even galvanized flat steel, long time buried in the soil or on the floor, the wall will be laying, easy to rust, if we use the normal flat iron, not to mention that, certainly rust, but the speed is much faster than galvanized flat steel!
Q:Round bar, flat steel, not reinforced
Flat steel: can be used to make iron, tools and machinery parts, building used as housing structure, escalator.All belong to section steel. Round steel can be used as reinforcing steel, which is often referred to as light round bar and primary steel. Flat steel is finished steel, not steel.
