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:Do lightning protection, lead out of the galvanized round steel, flat steel needs to be inspected?
When you buy hot galvanized round steel and flat steel, please provide inspection documents. In addition, in the procurement of materials must be explained that hot galvanizing, or else the business to provide you with cold plating will not work; there is a certain price gap between the two.
Q:Is the earthing electrode made of galvanized flat steel or bare copper wire?
The earthing device is divided into horizontal grounding and vertical grounding. The horizontal earthing body generally adopts hot-dip galvanized flat steel or hot galvanized round steel; the vertical grounding electrode adopts hot-dip galvanized steel, angle steel, steel tube, round steel and other materials.
Q:The difference between galvanized round bar and galvanized flat steel
Galvanized flat steel can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.Flat steel adopts negative deviation rolling, but according to actual weight delivery, the utilization ratio of steel plate increased by -5 percentage points. Flat can according to user needs, set the thickness, width and length of production, for the user to reduce the cut and save processes, reducing labor, material consumption, but also reduce the loss of raw materials processing, time saving, material saving. Products have been specialized in steel structure manufacturing, machinery manufacturing, automotive industry, mining machinery, lifting machinery and other industrial materials.
Q:How large is the flat steel used for equipotential grounding?
3.2.15 general equipotential connection with the sectional area of protective bonding conductors, shall not be less than the maximum protection of conductor size distribution line 1/2, protective bonding conductor cross-sectional area of the minimum and maximum value shall comply with the provisions of table 3.2.15.
Q:The function of ground lead out galvanized flat steel
1, galvanized flat steel, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of galvanized steel. Galvanized flat steel can be finished steel, also can be galvanized pipe blank and galvanized belt.2. Main uses: galvanized flat steel used as a useful material, can be used to make iron, tools and machinery parts, building for housing, structural parts, escalators.
Q:What are the standards for the use of galvanized steel angles and flat steel for grounding?
The distance of the grounding body from the building is over 1.5m, and the distance from the grounding rod of the independent lightning conductor is greater than 3m.(5) the connection of grounding wire and earthing body shall be done by lap welding.
Q:Why is it better to use round steel than that of flat steel in lightning protection?
Exposed on the outside with round steel, due to corrosion of small, dark buried flat steel, because of large welding area, reliable connection.
Q:Between the MEB and the power distribution cabinet with wire with the flat and why
Even if there is no condition to make the ring flat steel belt, the ground terminal box is usually reserved for the access pipe. If multiple power line is recommended to see 500 2.7. central area substation, but also set the MEB based, attracted special line, and the reinforced layer access line; flat steel (copper) can save you, ha ha
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:Round bar, flat steel, not reinforced
Round steel: 5.5-25 mm small round bars are mostly supplied by straight strips. They are commonly used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or as seamless steel tube billets.
