Usage/Applications of High Quality 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.

Production Flow of High Quality Mild Steel Flat Bar

The 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.

Packaging & Delivery of High Quality Mild 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.

 FAQ:

Q1: How soon can we receive the product after purchase?

A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q2: What makes stainless steel stainless?

A2: 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.

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.
Q:Hot dip galvanized flat steel specification 40X4, 60X6 meaning?
Hot galvanizing is a kind of anticorrosive process. It is coated with zinc on the surface of the plated parts. Zinc is relatively stable in the air. 40x4 60x6 is the width and thickness of the plated part, in mm
Q:How to connect the base of the tower crane and the flat steel? How can it be welded and connected?
How to connect the base of the tower crane and the flat steel?:It can be punched on a flat iron and connected by screws and multiple copper wires
Q:What is the surface area of flat steel 100*3 meters per metre?
Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
Q:What is the appearance of hot galvanizing and cold galvanized flat steel?
Cold galvanizing is zinc plating, the amount of zinc plating is very little, only 10 - 50g/m2, and its corrosion resistance is much different from that of galvanized pipe. Regular galvanized pipe manufacturer, in order to ensure quality, most do not use electro galvanized (Leng Du). Only small enterprises with small equipment and old equipment use zinc plating, of course, their prices are relatively cheaper. At present, the Ministry of construction has officially completed the following, the elimination of backward cold galvanized pipe, the future is not allowed to use cold galvanized pipe for water, gas pipes.
Q:The difference between galvanized flat steel 40*4 and galvanized flat steel 80*8 is the difference on the material list!
Here, your galvanized flat steel refers to the basic matrix is carbon content less than 0.18% carbon steel (Q235), after galvanizing (general hot plating), play the role of surface oxidation resistance, corrosion resistance. Generally used in the power sector, what you mention is the difference in size.
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 does QB stand for in Q235B flat steel? What's the difference between Q235B and Q235A?
There are also some subtle differences between Q235A and Q235B:1, chemical composition: Q235A:C:0.14~0.22:Mn:0.30~0.65; S:0.050;2, mechanical properties: tensile test without distinction, impact test A do not do, Q235B I-beam, Q235B angle steel, Q235B channel steel, Q235BH steel, Q235B flat steel B do 20 degree impact test, V type impact power (longitudinal) J no less than 27.
Q:Where can I buy ground level bending machine?
When lap welding is adopted, the welding length is as follows: 1. Galvanized steel bar is not less than 2 times its width, no less than 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. The length of galvanized round steel shall be no less than 6 times of its diameter, and shall be welded on both sides (when the diameter is different, the lap length shall be of big diameter).
Q:The distinction between flat steel and steel strip
Blue is to heat the steel or directly immersed in concentrated oxidizing solution in the air, material protection technology of oxide film on the surface of thin produce, also known as black. The blue steel parts can be carried out in the molten salt of sodium nitrite and sodium nitrate, can also be carried out at high temperature above 500 DEG C hot air and superheated steam, the more common is heating sodium nitrite in concentrated caustic soda. Solution composition, reaction time and the temperature of Bluing depends on steel matrix composition. Bluing film composition is magnetic iron oxide, the thickness of 0.5 to 1.5 microns, the color and the material composition and process conditions, a dark gray, dark blue, etc.. Bluing film separate corrosion resistance is poor, but the oil wax or paint varnish, corrosion resistance and friction resistance are improved. Blue, the workpiece has little effect on the quality of size and finish. It is commonly used in precision instruments, optical instruments, tools, hardness blocks and so on.
