Usage & Applications of Galvanized H beam

(1).used for the plant, high-rise building construction

(2).used for the bridge, shipment building

(3).used for lifting and transportation machinery, equipment manufacturing base building

(4).used for the support, foundation pile manufacturing

Packaging & Delivery of Galvanized H beam

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 in China, 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 Galvanized H beam

Further performance and design information for galvanizing can be found in BS EN ISO 14713-1 AND BS EN ISO 14713-2. The durability performance of a galvanized coating depends solely on the corrosion rate of the environment in which it is placed. Corrosion rates for different environments can be found in BS EN ISO 14713-1 where typical corrosion rates are given with a description of the environment in which the steel would be used.

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

Q:How to distinguish cold formed section steel and hot rolled section steel?: The difference between cold-formed steel and welded steel tubes is that welded steel pipes are mainly used for conveying fluids, such as gas and tap water. Petroleum, liquefied petroleum gas, steam, etc. The steel tube is subjected to a certain amount of pressure, while the cold-formed steel is used to make the structure. Under the action of external force, the cold-formed steel is required for the section, shape, size and mechanical properties of the section steel.

Q:What kind of steel is used in steel columns?: At present, there are 3 kinds of steel pile commonly used in engineering construction, they are steel pipe column, steel column and steel sheet pile.

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:Does the profile include H?: Profiles include section H steelThe online quote H steel and profiles in the angle of groove separate quotation, mainly because H steel has great use compared with the other, and the demand is relatively more, but in some cases, and H type steel I-beam can also substitute for each other.

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?: 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:Can the section steel butt joint in the end?: Docking is usually available.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.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.In short, the principle is that the strength of the butt joint is not weaker than that of other parts, and there is no greater stress.
