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:Galvanized steel flat welding occurs after the material itself crack.
Thermal cracking: most of the material being welded is alloy, and the solidification of the alloy starts from the beginning to the end, which is carried out in a certain range, which is the basic cause of the thermal crack.
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:How many years can hot dip galvanized flat steel be used?
Experience has shown that the extent of atmospheric corrosion varies from region to region. The service life of hot-dip galvanized flat steel is different in different environments.
Q:What is flat steel for?
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. The specification for wrought flat steel is expressed in millimeters of thickness * width. The specification is 20mm*40mm~160mm*300mm.
Q:Does the cable trench need grounding?
Cable trench grounding practices: ground pile using hot galvanized steel angle (50X5X2500), every 20 meters to hit a root. The pile top is 0.6 meters away from the ground, and the ground wire is made of galvanized steel flat bar (40X4). Cable grounding wire and cable groove on both sides of the main frame by welding, every 20 meters will ground wire leads and grounding pile welding, while the grounding cable trench on both sides of the ditch bottom connection, grounding wire used for 10 hot dip galvanized steel. All grounding devices need to be welded firmly at the joint, and the welding place is treated with asphalt.
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)?
GB50169-2006 in the 3.4.2 stipulates that the grounding body (line) shall be welded by lap welding, and its lap length shall comply with the following requirements:1. flat steel is 2 times its width (and welded with at least 3 edges);2. round steel is 6 times its diameter;3. round steel and flat steel connection, its length is round steel diameter of 6 times;
Q:What line is the LEB line, please? Is it wire or flat steel or galvanized round bar?
General requirements of the building's outdoor metal doors and windows, equipment shell, distribution box, etc., are required to do a second potential connection,It has not seen the specific technical requirements, we can use the past construction experience, building floor steel ring, Liang Gangjin, reinforced connecting line, equipment shell available 6 mm galvanized welded steel garden.
Q:Where is the use of flat steel in electrical use?
Flat steel is used for earthing and galvanized. Mainly used for grounding and grounding to objects (such as the need to join line equipment ground and grounding, lightning arrester and grounding) and grounding connection between the neutral line and the center point, connected with the neutral line
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 is 40x4 galvanized flat steel, please?
Refers to the galvanized flat steel, 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.
