Usage/Applications

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 Steel Flat Bar

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 Steel Flat Bar

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.

 

FAQ:

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: How do we guarantee the quality of our products?

A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q3: What makes stainless steel stainless?

A3: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

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: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:What is the difference between steel band and steel ring? Steel strip is flat steel, steel ring is made of steel
Q:80 * 80 * 4 galvanized flat steel is what specifications?
Galvanized square is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; or the cold hollow steel well in advance of the re galvanized square by galvanizing processing of pipe.
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:The technological process of flat steel
The working principle of precision steel production process of flat steel finishing machine is cold flat bad hair with two sets of upper and lower staggered leveling wheel thickness pre leveling and final leveling; with a pair of oppositely disposed finishing wheel in the width direction of extrusion, the width is compressed and reaches the expected parameters and the amount of compression can be adjusted; with 5 aspects of straightening straightening wheel arrangement of the staggered width. This system is mainly composed of a control box, finishing roller, pre leveling unit, finishing unit, straightening unit.
Q:What is the surface area of flat steel 100*3 meters per metre?
2X (0.1x1+0.003x1+0.1x0.003) =0.2066 with a surface area of 0.2066 square meters.Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel.
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:Can lightning protection earthing steel bar be directly welded with thread steel?
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 representation of flat steel?
In use, it has advantages over steel platesFlat steel adopts negative deviation rolling, but according to actual weight, the utilization ratio of steel plate is 1~5 percentage points higher than that of steel plate.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.
