Usage/Applications of Q235 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 Q235 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 Q235 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.

Q:What is the quota for the flat steel used in the lightning belt -40*4?
Fixed the lightning belt installation "is based on the 8 mm galvanized steel park system, you can make the material conversion and adjustment.
Q:Galvanized flat steel how much is one meter?
The price of galvanized flat steel is about 6200, so the price is 40 * 4 * 0.00785 * 1.06 * 6.2=8.3 yuan per meterGalvanized pipe price is about 6500, DN25:2.57 * 6.5=16.7 yuan / meter, DN32:3.32 * 6.5=21.58 yuan / meterAngle steel price 5000, 4# angle steel: 2.422 * 5=12.1 yuan / meter
Q:How large is the flat steel used for equipotential grounding?
According to the GB 50054-2011 3.2.15 6# responses (table 3.2.15), the distribution system of equipotential bonding conductor may be 25mm2 copper; when the 1/2PE line section of not less than the case, must use 25mm2 copper (or the equivalent capacity of aluminum or steel); according to the GB 50057-2010 5.1.2 (table 5.1.2), lightning protection system equipotential bonding conductors with 16mm2 copper, can meet the minimum section of all the connecting parts of the requirements of lightning protection device. Therefore, "lightning protection system equipotential" equipotential bonding conductor specification is greater than "distribution system equipotential" equipotential connection conductor is not necessarily established.
Q:What is the weight calculation formula for galvanized flat steel and galvanized steel angles?
That is volume * density = weight.For example: L50*5 angle, general case, hand count is (0.05*2-0.005) *0.005*7850=3.729kg/m; 6m is 3.729*6=22.37kg [formula is W= (both long - and angle angle thickness) * angle thickness *7850* meters, of which 7850 were iron density value after conversion unit after multiple values, namely 7850kg/m3. The length and thickness and the number of meters into units are in meters, the weight of the unit is kg W.
Q:How can copper clad steel ground electrode and galvanized flat steel be welded?
Using hot fusion welding. It is welded firmly and will not corrode the weld because of electrochemical action.The common copper clad steel wire electrode is copper wire.
Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40*4 galvanized flat steel GB permitted negative deviation value is the thickness deviation value is 0.2mm, the deviation 0.4mm, the width deviation value is the upper deviation 0.5mm, lower deviation 1.0mm
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: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:What is the difference between steel band and steel ring? The steel strip is flat steel and the steel ring is made of steel. Am I right?
A steel strip is a steel strip of relative range, and can be called a steel strip when the width is less than 1000.
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.
