Usage & Applications of Galvanized Flat Bar
Widely used for construction,Fabrication , Ship building, Machinery manufacturing, Steel structure
Packaging & Delivery of Galvanized Flat 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 in
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 Flat Bar
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: What does "M" mean?
- M section steel: sectional shape steel like M.
- 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: What does "BH" mean?
- BH is welded to H just, and RH is hot rolled H steel.
- 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 kind of steel is used in steel columns?
- Compared with other steel piles, steel pipe piles have their own advantages in many aspects, such as long joint welding, single pile bearing capacity, bending rigidity and penetration ability.
- Q: What is special steel?
- Military materialsOther varieties are mainly some special quality profiles. Including hollow steel, oxygen bottles, industrial pure iron, hot rolling, cold heading steel easy to cut steel, D60, S/5A, F18, F11 etc., behind several are. High quality steel is not large, medium and small, round and Fang Gang divided into groups according to specifications from, such as 8-10mm, 11-15mm, 18-20mm, 205-245mm. flat area by large, medium and small flat. Six angle distance is not grouped. But the quality of steel group distance is no substitute for detailed specifications, in the document should be filled concrete specifications. Quality profile specification is simple, the vast majority of round steel. In addition, flat steel, and Fang Gang six chest steel, hollow steel, shaped and so on hot rolling (forging) size deviation of high-quality steel, Fang Gang, the six angle of the ordinary high accuracy and precision of two. And has a more precise cold drawn profile surface size and smooth surface polishing, polishing, but also some After polishing or round processing. The polished surface is exquisite, called steel. High quality profiles are rarely used, mostly through the use of the unit for further processing and after heat treatment, therefore, in addition to chemical composition, but also to ensure the mechanical properties after heat treatment.
- 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.
- Q: What are the common types of profiled steel?
- Complex section steel has: I-beam, channel steel, steel, elevator rail, steel sheet pile, and various kinds of agricultural machinery, machinery manufacturing and construction of special-shaped steel.Section steel according to production methods are: hot-rolled steel, cold-formed steel, welding, H steel, etc.
- 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%.
