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:Are galvanized flat steel and angle steel the same price?
This is not to say that depends on how you choose, simply said the product itself is good a bit different, if you choose the amount of zinc is not the same, the price will be different. If there is anything you need for this piece of steel, you can call on me. I am in Tianjin, Tangshan, a generation of steel business.
Q:Are there any differences between flat iron and flat steel?
There are many kinds of iron ore, magnetite, hematite, corresponding to the main components of the ore should all know, or in a similar "write reaction equation" with the topic of carbon monoxide reduction of magnetite occurs, will be at a loss what to do. Next should mainly reflect the principle on iron smelting to understand the reducing agent for iron reduction, must pay attention to the test of the formulation of the phenomenon - "red brown powder into black" (which is often the examination content). From here, the principle of blast furnace ironmaking is approximately the same. For some knowledge in actual production, we should understand the basic structure of the blast furnace five furnace two, three import and export ", and each part of the chemical reaction, the slag formation reaction, the need to pay attention to is: the composition of blast furnace gas is a mixture of gases such as carbon monoxide, carbon dioxide and nitrogen, after purification to it is a gas discharge, good fuel.
Q:Construction of electrical grounding steel flat buried anti-corrosion requirements, galvanized steel flat welding parts should be done anti-corrosion treatment, not welding parts are also doing anti-corrosion treatment?
The welding part needs to corrosion because in the welding process the heat melted metal surface coating, so this part, other parts such as did not cause damage to the galvanized layer in the construction process, there is no need for antiseptic treatment.
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:Where is the use of flat steel in electrical use?
Flat steel is used for earthing and galvanized. Mainly used for grounding and grounding to objects (such as the need to join line equipment ground and grounding, lightning arrester and grounding) and grounding connection between the neutral line and the center point, connected with the neutral line
Q:What do the numbers in the steel HN346*174*6*9 refer to?
I-beam, channel and angle steel are widely used in industrial buildings and metal structures, such as factories, bridges, ships, agricultural machinery, vehicle manufacturing, transmission towers, transport machinery, often in conjunction with the use of. Flat steel is used as a bridge, a housing, a fence, a transmission ship, a vehicle, etc. on a construction site. Round steel and square steel are used for all kinds of machine parts, agricultural machinery parts, tools and so on.
Q:50*4 hot dip galvanized flat steel can be used as grounding. How many square feet can be used instead of ground wire?
In general, our project has no discretion to select the ground wire specification of 16mm. Europe is 25mm2
Q:Earthing flat steel and earthing main line
The flat steel is connected to the ground system, and the grounded line is connected to the protected equipment
Q:80 * 80 * 4 galvanized flat steel is what specifications?
Galvanized square pipe.Specification: 80 * 80 * 4 is the dimension of galvanized square pipe. That is to say, the length and width of the inner diameter of the nozzle are 80mm, and the thickness of the tube wall is 4mm.
Q:How to use -40*4 galvanized steel bar to do grounding electrode?
The combination of conductors or conductors that are buried in the earth so as to connect with the earth is called a ground electrode. The grounding electrode is the electrode which is in full contact with the ground and realizes the connection with the earth. In the electrical engineering, the grounding electrode is made of a plurality of 2.5M long, 45X45mm galvanized steel angles, and is nailed at the bottom of the 800mm deep groove, and then is drawn out with the lead out line.
