Galvanized Steel Round Bars

Usage & Applications of Galvanized Steel Round Bar

(1).used for metallurgical, mechanical, electrical construction field

(2).used for ships, military (armored) Construction

(3).used for outside engineering, machine tool base, automobile rear of products

Packaging & Delivery of of Galvanized Steel Round Bar

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.

If loading by container the marking is not needed, but we will prepare it as customer request.

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 of Galvanized Steel Round Bar

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.

Q:How to distinguish cold formed section steel and hot rolled section steel?: Hot rolled steel is a kind of steel with various geometrical cross section formed by heating billet. According to the different angles can be divided into flat steel, steel section, steel and I-shaped steel and hot-rolled L steel; steel according to the different section shape, divided into simple and complex section or section section and section three steel cycle:The characteristics of the simple section are the cross section, any point on the periphery as a tangent, generally not cross section, such as round steel, square steel, six angle steel, flat steel, triangular steel, arch steel and elliptical steel.Complex sections include angle steel, I-beam, channel steel, T steel, H steel, Z steel, rail, steel plate pile, window frame steel and other miscellaneous section steel;The periodic section shape and dimension along the length direction of the steel section changing periodically, such as rebar, axle and steel ploughshare.

Q:What is special steel?: Agricultural steelAgricultural steel is the main means of agricultural production and agricultural private or semi private steel, mainly are: Farm steel: Farm steel is commonly used steel for rural primary system of small tools and general civil tools. Main is a small section of round steel, flat steel and other varieties of composite steel composite steel billet, billet and hoe sickle knife blank, used in the manufacture of sickle, hoes and other small tools and other tools (such as knife, etc.). This kind of composite steel consists of two same components of the carbon steel hot rolled, low carbon steel is outside the body, soft and tough body steel seismic, good adhesion, easy sandwiching a layer of grinding. Leaf blade steel containing carbon, manganese, hard and wear-resistant, polished production tool edge is very sharp.

Q:What does "BH" mean?: Section steel is a strip steel with definite section shape and size. It is one of the four big kinds of steel (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:What does "M" mean?: 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:Does the profile include H?: Another reason is that H steel is made late in our country, so people are used to distinguish it from other shapes. But in the strict sense, H steel is a kind of section bar.

Q:Elastic modulus of section steel: Generally speaking, the elastic body exerts an external function, and the elasticity experiences the change of the shape (called strain). The general definition of the elastic modulus is that the stress is divided by the strain. When the material is in the elastic deformation stage, its stress and strain should be changed into a positive proportion (that is to say, according to Hooke's law), and the coefficient of proportionality is called the elastic modulus.

Q:Can the section steel butt joint in the end?: Bolt connection also requires lining plate, pay attention to bolt size, quantity and spacing. To calculate whether thin-walled steel itself will be crushing, the solution is solder paste board, and bolt holes. The principle is that the strength of the butt joint is not weaker than that of other parts, and there is no greater stress.

Q:What are the common types of profiled steel?: Section steel is divided into two types: simple section steel and complex section steel.Simple section steel: steel, wire rod, square steel, flat steel, six angle steel, triangular, elliptical steel, steel arch steel, etc..

Q:What kind of steel is used in steel columns?: The steel sheet pile has various forms, and the sides of the steel sheet and the joint groove are different in shape. The second plate, after the first one is in place, takes the front sheet of the sheet pile and the side notch is used as the driving point. As a result, a plurality of sheet piles may form relatively complete sheet pile walls along the coast (or bank of the river). In addition, a group of steel sheet piles can be used for temporary retaining protection when the foundation pit is excavated or excavated.
