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:Cold rolled flat steel standard. What is cold rolled flat steel?
Flat steel, width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:What is the tensile force of the galvanized flat steel of 20*3?
According to "hot rolled flat steel size, shape, weight and allowable deviation", GB 704-88:Ordinary class allows upper deviation +0.3mm, lower deviation -0.5mm; higher allowed upper deviation +0.2mm, lower deviation -0.4mm, the upper deviation is not to think, do not exceed the next deviation is good.
Q:Please: hot galvanized flat steel and copper clad steel ground!
Compared with galvanized flat steel and other grounding materials, copper clad steel ground wire features: 1, corrosion resistance is better: no residual inside the bimetal, better corrosion resistance. The horizontal continuous casting process adopts high temperature melting, and the residue is calcined to overflow the copper surface, and can not be left in the copper clad steel conductor, so the corrosion phenomenon can not occur inside. 2 、 better electrical performance: the surface of oxygen free copper, good conductivity, the inner layer of high-quality carbon steel, skin effect principle, conductive, magnetic characteristics are excellent. The resistance is much lower than conventional materials such as steel, galvanized steel, etc. the surface layer is oxygen free copper.
Q:How large is the flat steel used for equipotential grounding?
To divide 2 kinds of equipotential, one is the equipotential of the distribution system, and the other is the equipotential of the lightning protection system; two. The latter specification is greater than the former
Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40 is the width of the section steel, 4 is the thickness of the steel, and the unit is mm.Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:What is the rolling range of the micro cold rolled flat steel production line?
Ferrous metals are alloys of iron and iron. Such as steel, pig iron, iron alloy, cast iron and so on. Steel and pig iron are based on iron, carbon as the main additive elements of the alloy, collectively referred to as iron carbon alloy.Pig iron is the product of smelting iron ore into a blast furnace. It is mainly used for making steel and casting.Put the casting pig iron smelting in cupola, to obtain iron (liquid), the liquid cast iron cast into casting, the cast iron is cast iron.
Q:Can roof strip be replaced with steel pipe instead of flat steel and round steel? Are there any examples of practical use?
Other examples are not used, mainly because the price of steel pipe is more expensive than flat steel and round steel
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: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:The technological process of flat steel
The working principle of precision steel production process of flat steel finishing machine is cold flat bad hair with two sets of upper and lower staggered leveling wheel thickness pre leveling and final leveling; with a pair of oppositely disposed finishing wheel in the width direction of extrusion, the width is compressed and reaches the expected parameters and the amount of compression can be adjusted; with 5 aspects of straightening straightening wheel arrangement of the staggered width. This system is mainly composed of a control box, finishing roller, pre leveling unit, finishing unit, straightening unit.
