Usage & Applications of Stainless Galvanized Flat Bar of  High Quanlity  with Leigth 6M/12M

Widely used for construction,Fabrication , Ship building, Machinery manufacturing, Steel structure

 

 Packaging & Delivery of Stainless Q235/275 Alloyed Mild Steel Flat Bar with High Quality

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made inChina, shipping marks and other information request by the customer.

 4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

 5. Delivered by container or bulk vessel

 

Production flow of Stainless Q235/275 Alloyed Mild Steel Flat Bar with High Quality

The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated.

A typical hot-dip galvanizing line operates as follows:

  • Steel is cleaned using a caustic solution. This removes oil/grease, dirt, and paint.

  • The caustic cleaning solution is rinsed off.

  • The steel is pickled in an acidic solution to remove mill scale.

  • The pickling solution is rinsed off.

  • A flux, often zinc ammonium chloride is applied to the steel to inhibit oxidation of the cleaned surface upon exposure to air. The flux is allowed to dry on the steel and aids in the process of the liquid zinc wetting and adhering to the steel.

  • The steel is dipped into the molten zinc bath and held there until the temperature of the steel equilibrates with that of the bath.

  • The steel is cooled in a quench tank to reduce its temperature and inhibit undesirable reactions of the newly formed coating with the atmosphere.

 

FAQ:

Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

 

Q4: What makes stainless steel stainless?

A4: 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:Construction of electrical grounding steel flat buried anti-corrosion requirements, galvanized steel flat welding parts should be done anti-corrosion treatment, not welding parts are also doing anti-corrosion treatment?
The welding part needs to corrosion because in the welding process the heat melted metal surface coating, so this part, other parts such as did not cause damage to the galvanized layer in the construction process, there is no need for antiseptic treatment.
Q:Galvanized flat steel how much is one meter?
Formula of flat steel: width * thickness * 0.00785 (kg/m), zinc coating weight: 1.06Galvanized pipe formula: (outer diameter wall thickness) * wall thickness * 0.02466 * 1.06, DN25 galvanized pipe outer diameter 33.5, GB thickness 3.25, weight: 2.57kg/m, DN32, outer diameter 42.3, wall thickness 3.25, weight: 3.32kg/m. DN stands for nominal caliber.Angle formula (approximate): edge width * thickness * 0.015, 4# angle iron weight 2.422kg/m
Q:Construction of lightning protection ground galvanized flat steel approach, need to retest test? What's the test?
Hot rolled flat steel is a general purpose rectangular cross section strip. Its specifications are expressed in millimeters of thickness / width, flat steel can be finished steel, used for components, ladders, bridges and fences, etc.. Flat steel can also be used to weld rigid steel and billets and slabs of laminated sheets. This standard is applicable to hot-rolled flat steel with rectangular cross section. Measurement: flat length and length of flat steel, according to the theoretical weight of delivery.
Q:Is medium plate steel flat?
No, the production process is different.Flat steel can replace a small part of the plate (steel), flat steel is generally fixed rolling, length can be fixed, 1 meters, 30 meters can also do.
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:What is the weight calculation formula for galvanized flat steel and galvanized steel angles?
That is volume * density = weight.For example: L50*5 angle, general case, hand count is (0.05*2-0.005) *0.005*7850=3.729kg/m; 6m is 3.729*6=22.37kg [formula is W= (both long - and angle angle thickness) * angle thickness *7850* meters, of which 7850 were iron density value after conversion unit after multiple values, namely 7850kg/m3. The length and thickness and the number of meters into units are in meters, the weight of the unit is kg W.
Q:Where is the use of flat steel in electrical use?
The main use of galvanized grounding in building electric device, equipotential connection, such as transformer neutral point grounding, power distribution cabinet repeatedly grounding of electrical equipment and protective metal pipeline grounding and equipotential connection of buildings, building the underground lightning belt (that is the root of a plurality of buried steel the grounding electrode connected), building lightning deflectors and high-rise building equalizing ring (without using the building structure reinforcement), cable bracket (laminated cable trench or substation room or subway) or slot (or tray tray) metal grounding connection, welding and in the use of bolt connection, look to determine the design requirements and conditions, generally buried (wall) welding used in concrete or concealed, must be at least three surface welding, welding (two flat lap length Larger than the width of flat steel 2.2-2.5 times, round steel and flat steel lap length is greater than round steel 6-8 times, welding mouth does not allow slag, meat and remove welding slag, welding finished, in addition to concrete, do anti-corrosion, rust prevention;
Q:Can lightning protection earthing steel bar be directly welded with thread steel?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:What are the standards for the use of galvanized steel angles and flat steel for grounding?
The distance of the grounding body from the building is over 1.5m, and the distance from the grounding rod of the independent lightning conductor is greater than 3m.(5) the connection of grounding wire and earthing body shall be done by lap welding.
Q:The distinction between flat steel and steel strip
The first is to use cyanide cyanide salt, it is commonly referred to as the "cyanide", it is the metal surface while being carbon atoms and nitrogen in a chemical heat treatment process of saturated (cyanide containing carbon, nitrogen, assuming the metal is a, valence +n, cyanide formula a (CN) n).
