Q1: How do we guarantee the quality of our products?

A1: 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.

Q2: What makes stainless steel stainless?

A2: 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.

Q3: Can stainless steel rust?

A3: 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: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: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: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:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
The angle between the bridge is connected or welded together by rivets, but in accordance with the relevant provisions of the State Grid, not admit that these are valid connection. At the same time in order to protect the ground, must have a grounding cable connection between all seams of metal objects, so that it can recognize all of its bridge is connected to one end, through one or a plurality of total grounding grounding.
Q:The difference between galvanized flat steel 40*4 and galvanized flat steel 80*8 is the difference on the material list!
There are many kinds of flat steel, Q235A/B/C, mainly depends on the location of your specific requirements, what is needed?;
Q:How can copper clad steel ground electrode and galvanized flat steel be welded?
Using hot fusion welding. It is welded firmly and will not corrode the weld because of electrochemical action.The common copper clad steel wire electrode is copper wire.
Q:What do the numbers in the steel HN346*174*6*9 refer to?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
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:What is the difference between steel band and steel ring? The steel strip is flat steel and the steel ring is made of steel. Am I right?
Steel rolls are also called steel belts. There is no difference between them. They are not flat steel
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.
