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 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:How to grounding lightning protection grounding?
In the cupboard and a MEB box, distribution box shall be the total PE bus, building low voltage power distribution cabinet. The 2 main vertical bars in the column are used for grounding on the line when the potential is grounded, and then the hot galvanized flat steel is led to each LEB terminal box with 40*4. In the elevator shaft from the elevator pit 0.2 meters, and the elevator shaft end below each embedded 100*100*8 hot galvanized flat steel piece, flat steel and column 2 as the main vertical grounding line and welding.
Q:Difference between cold drawn flat steel and flat steel
Cold drawn flat steel: steel, smooth surface,Flat steel: steel is relatively soft, flatness, no cold drawn flat steel
Q:Do I need to make the ring galvanized flat steel ground connection between the electric well and the distribution room?
There is also a dark, in the foundation of the house to consider the distribution of indoor total potential imbalance, in the basic reinforcement welding has been laid. Later, when installing the equipment, just connect in place
Q:What is the use of slitting flat steel?
Flat cut flat steel, also called fine shearing flat steel strip, can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.
Q:What is the difference between flat steel and steel strip?
It belongs to the conventional flat stainless steel series, steel to stainless steel sheet series, steel is cold rolled sheet, and a flat surface of hot rolled and cold rolled surface, flat iron is a common type of steel does not contain nickel, but sometimes some customers habitually called stainless steel flat steel flat iron.
Q:How can copper cables and flat steel be welded together?
As a thin strip of copper or copper brazing Hanbian flat, the flat copper or steel crimping brazed or welded to the ground flat strip. Not copper brazing, tin soldered or crimped copper braid, then copper tape terminal is connected to the flat.
Q:What's the difference between hot rolled flat steel and flat rolling tool flat steel?
Hot rolled flat rolled hot rolled flat steel is a general purpose rectangular cross rolled strip. The specifications are expressed in millimeters of thickness * width, flat steel can be finished steel, used for components, ladders, bridges and fences, etc..
Q:Why do some buildings need a steel bar around the top?
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:The difference between use and performance of hot rolled flat steel and longitudinally cut flat steel is discussed
Hot rolled flat steel (hot rolled flat steel strip):Mostly produced by small factories, the raw material sources are disordered and the material can not be guaranteed. Therefore, the mechanical properties of hot-rolled flat steel are greatly different. Hardness, tensile strength, elongation, weldability are often unpredictable.
