 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:Cold rolled flat steel standard. What is cold rolled flat steel?
Flat steel, 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. Section steel is one of the four major steel products (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..
Q:How to determine the application direction of steel grid plate
This order must be strict and clear. The steel grid plate in the length direction (flat length direction) on at both ends of a supporting beam, i.e. use or the use of slot, and ends in the width direction can not need support. Because the bearing capacity of steel plate mainly from the flat direction. For example drain cover
Q:What about the installation height of the socket and the height of the ground flat steel?
If the construction unit, design institute and contact Party A drawings or design change
Q:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
Without laying, the cable bridge, each section of the joint, there is a copper wire to prepare flat belt connected, it is bridge grounding jumper cable.
Q:What is the weight calculation formula for galvanized flat steel and galvanized steel angles?
(1) grounding wire is generally made of 40mm * 4mm galvanized flat steel.(2) galvanized steel or angle steel for earthing body. The diameter of the steel pipe is 50mm, the wall thickness of the pipe is not less than 3.5mm, and the length is 2 to 3m. Angle iron shall be 50mm * 50mm * 5mm.(3) the top of the grounding body from the ground 0.5 ~ 0.8m, in order to avoid thawing soil, soil resistivity or steel angle as the root number of the ground around the body and decide, generally not less than two, each spacing is 3 ~ 5m(4) the distance between the grounding body and the building is over 1.5m, and the distance between the grounding rod and the independent lightning rod is greater than 3m.(5) the connection of grounding wire and earthing body shall be done by lap welding.
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:How can copper cables and flat steel be welded together?
The copper cable is pressed into the nose. It is punched through the steel and screwed,The national standard atlas is connected with a total equipotential terminal box.
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 difference between steel band and steel ring? Steel strip is flat steel, steel ring is made of steel
Q:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Connect the equipotential terminal box to the ground flat iron and cannot use plain flat steel. What level of ground steel must be used in AC electrical grounding standards, and must be hot-dip galvanized flat steel, the first is corrosion protection, and the second is long acting. Whether or not galvanized is always corroded, all national standards, industry standards, local standards are required to use hot-dip galvanized flat steel. And, depending on where it was buried, the size of flat steel was decided.
