Galvanzied Round Bar

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

Galvanzied round bar steel

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?: Cold-formed steel is a product of various cross sections bent in cold form with steel plates or strips. Cold formed section steel is an economical light section steel, also called cold-formed steel section or cold bending section. Cold-formed steel is the main material for making light steel structures. It has various kinds of super thin and reasonable shapes and complicated sections which can not be produced by hot rolling. Compared with hot-rolled steel, in the same section area, turning radius can be increased by 50 ~ 60%, moment of inertia can be increased 0.5 ~ 3 times, so it can be more reasonable to use the strength of the material; and ordinary steel structure (from traditional I-beam, channel steel and angle steel and steel plate made of steel structure comparison) that can save steel by 30 ~ 50%.

Q:What kind of steel is used in steel columns?: Section I and H of steel reinforced piles belong to the common section shapes in steel reinforced concrete piles. I and H type steel piles can be used in horizontal load and vertical load bearing. The steel pile has stronger penetration ability in many kinds of strata, moreover, its disturbance to stratum is slight, it is a kind of partly squeezed soil pile. If the distance between the driving pile and the center is smaller, the H steel pile can be used to replace other piles to prevent the ground fault caused by piling operation, such as lateral extrusion, uplift and so on.

Q:What does "BH" mean?: In accordance with the different smelting quality of steel, steel is divided into ordinary steel and high quality steel. According to the current catalogue of metal products, ordinary steel can be divided into large section steel, medium section steel and small section steel. The section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its sectional shape.

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: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 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 "M" mean?: M section steel: sectional shape steel like M.

Q:Can the section steel butt joint in the end?: If welding, it is mainly worried that the welding is not strong and the welding stress is too large. The wall thickness of the section steel is thin, and the butt welding itself is the most unreliable. So, in the joint lining board, fillet welded. Attention is paid to reducing stress in the process.

Z GLOSS,a well-known enterprise specializing in the hot galvanizing, the main product is galvanized square tube,retagular tube, angle steel and U channel steel which be widely used in the project of curtain wall decoration, electric power and steel structure construction, etc. Since the establishment of our company, we have been completely implementing ISO9001 quality management system.
