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: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:8 what is the flat density?
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel.
Q:Lightning protection grounding, what is called three surface welding?
The grounding position of the grounding body shall not be less than 3m; when the ground is embedded in the garbage or ash, it should be changed and compacted.The grounding body (line) shall be connected by welding, the welding seam should be full and adequate mechanical strength, no slag, undercut, crack, weld, welding defects such as pores, knocking the net after a drug paper, brush asphalt anticorrosive processing.
Q:Are galvanized flat steel and angle steel the same price?
No, generally speaking, galvanized flat steel is more expensive than angle iron
Q:Construction of lightning protection ground galvanized flat steel approach, need to retest test? What's the test?
Forged flat steel is a forged strip of steel with a rectangular cross section. Forging injustice can get certain shape and size and forgings, casting microstructure of the steel is remarkably improved, increase the density of steel; can change the distribution of the fiber structure, clear anisotropy, improve the mechanical properties of the metal, so that the strength and toughness of steel are improved; and it can be used to process the plastic lower high Shuogang and high alloy steel. Forged flat steel is mainly made of high quality alloy steel, mainly used as springs, tools and important mechanical parts.
Q:Does the cable trench need grounding?
According to the design requirements of excavation and masonry, the groove side wall welding force angle, steel frame and required to ground, covered with the cover of the underground channel, that is, cable ditch. Its purpose is to lay underground tunnels for cables.
Q:The grounding electrode 50 angle steel and the ground wire 50, the flat steel lap welding, according to the specification 169 needs the flat steel to be late 90 degrees, bends close to the angle steel side, the overlap width is 4 times (200mm)?
Flat steel and steel, flat steel and angle steel, in order to reliable connection, should be in addition to the contact regions on both sides of the welding, and welding with arc steel should be bent into (or rectangular) clips or directly from the strip itself curved (or rectangular) and steel (or steel) welding.
Q:The difference between galvanized round bar and galvanized flat steel
Galvanized round steel refers to the cross section of round solid steel. The specifications are expressed in millimeters of diameter, such as 50, which means a round bar of 50 millimeters in diameter. Round steel is not the same as other steel bars. Round steel is round in shape and has no ribs and no ribs, which makes the bonding strength between round bar and concrete very small.Round steel (grade 1 steel) belongs to ordinary low carbon steel with low strength. However, the plasticity of the round bar is stronger, that is, the round steel has a larger deformation before it is pulled off.
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 flat steel, please?
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.
