Packaging & Delivery of Carbon 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.

 

Production Flow of Carbon Steel Flat Bar

The Carbon 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.

 

FAQ:

Q1: What makes stainless steel stainless?

A1: 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.

Q2: Can stainless steel rust?

A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:Between the MEB and the power distribution cabinet with wire with the flat and why
How many will do is a box, the basement has the condition to make the ring to spread the flat steel (copper) to take one circle, many places reserve the ground terminal box foundation to attract, the access flat steel belt;
Q:Construction of lightning protection ground galvanized flat steel approach, need to retest test? What's the test?
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.
Q:What is the quota for the flat steel used in the lightning belt -40*4?
Fixed the lightning belt installation "is based on the 8 mm galvanized steel park system, you can make the material conversion and adjustment.
Q:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Equipotential terminal box is the protection main buildings, water gas pipes, heating and refrigeration, cooling system, link building components such as metal parts, in order to meet the anti shock protection requirements of the electrical contact voltage of less than 50V. Is an important component of modern building electrical appliances, is widely used in high-rise buildings.
Q:Are there any differences between flat iron and flat steel?
We should know the difference between iron and steel is carbon content of different (2%-4.3% and 0.03%-2%), and then understand the classification of iron and steel respectively, and focus on the actual use of various substances such as name, name of gray cast iron, commonly used in the manufacture of various castings etc.. This part of the study should be based on contrast, although the data theory is not many, but we should pay attention to, because the exam often in the form of common sense multiple-choice questions appear.
Q:What's the difference between stainless steel flat bar 304 and 316
316 stainless steel flat type is 316, the material is stainless steel. The stainless steel should be a bundle of delivery, the bundle passes, bundle length should be specified. Stainless steel flat is generally naked, delivery, transportation and storage are required to pay attention to moisture.
Q:-40x4 hot galvanized flat steel, a water 1m, what do you mean?
Water is to protect the wall foundation using cement mortar width not less than 600 of a circle along the walls of the cement ground, if the main part of the project before the electrical engineering, auxiliary grounding length less than in bulk water, auxiliary grounding, ditching to destroy the water, so that the design requirements of 1 meters water is conducive to the construction of welding, may be more than one meter in order to facilitate their work.
Q:The technological process of flat steel
The spring flat steel is made by converter smelting process. Compared with the prior art, the utility model has the following advantages and positive effects:1. refining flat steel with converter, mainly using hot metal as raw material, less harmful elements in molten iron, the quality of flat steel produced is guaranteed.2., because of the high rate of finished products and less power consumption, the cost per ton is lower than that of the electric furnace.3. the molten steel is directly cast into billets, omitting the cogging process and reducing the cost.4., continuous casting billet, fixed rate is high, can ensure flat steel fixed rate, to meet the needs of users.
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:Hot dip galvanized flat steel specification 40X4, 60X6 meaning?
Hello Hot galvanized flat steel specification 40* 4 stands for flat steel with a height of 40 mm and a thickness of 4 mm60* 6 stands for flat steel with a height of 60 mm and a thickness of 6 mm..
