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:

Q1: Why buy Materials & Equipment from OKorder.com?

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:What is the tensile force of the galvanized flat steel of 20*3?
According to "hot rolled flat steel size, shape, weight and allowable deviation", GB 704-88:Ordinary class allows upper deviation +0.3mm, lower deviation -0.5mm; higher allowed upper deviation +0.2mm, lower deviation -0.4mm, the upper deviation is not to think, do not exceed the next deviation is good.
Q:What is the quota for the flat steel used in the lightning belt -40*4?
I have also checked the quota, but there is no flat steel laying in the lightning protection and grounding device of the electrical installation of the second book. I usually refer to the grounding bus.
Q:How is three grade steel connected to ground flat steel?
HRB400 can be directly welded by hand arc welding with Q235 flat steel into electrical circuit. (I have done two sets of tensile tests last year, qualified).
Q:Are galvanized flat steel and angle steel the same price?
This is not to say that depends on how you choose, simply said the product itself is good a bit different, if you choose the amount of zinc is not the same, the price will be different. If there is anything you need for this piece of steel, you can call on me. I am in Tianjin, Tangshan, a generation of steel business.
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 technological process of flat steel
The production process can be summarized as: pre leveling, finishing, straightening and leveling. Flat /a/b width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure 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. Flat steel is divided into two kinds according to its shape: flat spring, flat steel and single side double slot spring flat steel. Hot rolled spring flat steel is mainly used in the manufacture of automobiles, tractors, railway transportation and other mechanical leaf springs.
Q:What's the meaning of ground flat steel -60*8 hot dip galvanizing?
Hot galvanizing process: finished pickling and washing and plating liquid - drying - plating - cooling - drug - Cleaning - Polish - hot galvanized, hot galvanized 1 completed by the more ancient hot plating method development, since 1836 the French to hot galvanizing applied in industry has been more than 170 years since. The history of the. In the past thirty years, with the rapid development of cold rolled strip steel, galvanizing industry has been developed on a large scale.
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:Can roof strip be replaced with steel pipe instead of flat steel and round steel? Are there any examples of practical use?
Other examples are not used, mainly because the price of steel pipe is more expensive than flat steel and round steel
Q:Please: hot galvanized flat steel and copper clad steel ground!
Copper layer adhesion is high: because the copper layer and the surface of the steel is the combination of molecules, so the degree of adhesion is high, in the stranding of synthetic strands, the copper layer will not be damaged, there will be no separation, skin cracking and cracking.
