Usage/Applications of Standard Size Q235 Hot Rolled Steel Flats from China

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 Standard Size Q235 Hot Rolled Steel Flats from China

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 Standard Size Q235 Hot Rolled Steel Flats from China

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: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:Earthing flat steel and earthing main line
Grounding flat ground belongs to the material, the grounding line belongs to the grounding line, grounding flat steel used for grounding grid, the grounding line is also one of the flat ground, for connecting the grounding grid, the grounding grid extends to the metal shell of the substation ground of all electrical equipment, and the grounding grid connected together.
Q:Lightning protection grounding, what is called three surface welding?
Lightning protection, grounding, the three sides of the welding:The buried depth of the grounding body shall not be less than 1m at the top, and the steel pipe grounding body shall be vertically configured.The length of the vertical grounding body shall not be less than 2.5m, and the spacing between them shall not be less than 5m.
Q:What is the difference between flat steel and steel sheet material
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. 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 difference between flat steel and steel strip?
Steel strips generally refer to sheet metal, and flat steel generally refers to medium and heavy plateFlat steel hot rail and cold drawn
Q:Earthing flat steel, width, overlap face, bolt, big country net
Now it's basically 12mm open holes. Coupled with the expansion screw directly fixed on the wall of the backward technology, electricity and telecommunications has been the traditional practice.
Q:What are the standards for the use of galvanized steel angles and flat steel for grounding?
The top of the grounding body from the ground 0.5 ~ 0.8m, in order to avoid thawing soil, soil resistivity or steel angle as the root number of the ground around the body and decide, generally not less than two, each spacing is 3 ~ 5m
Q:Where can I buy ground level bending machine?
When galvanized round steel is connected with galvanized flat steel, its length is not less than 6 times of the diameter of round steel. If necessary, it should be welded at right angle with auxiliary round steel or flat steel.
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.
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!
