ភាសាខ្មែរSteel Flat Bar is one of the most popular construction materials today because of its high durability and good load-bearing capacity. So what is a Steel Flat Bar, and what types of flat bars are currently used the most? Let’s find out the details of Bao Tin Steel in this article.
What is the Steel Flat Bar? Features and Applications
General characteristics of Steel Flat Bar
Steel Flat Bar. This type of steel is produced from steel plates, coils, or sheet metal. The production process of steel flat bars includes flattening and cornering to ensure standard technical parameters. The main components of steel flat bars include C, Si, Mn, Ni, Cr, P, and S.
A steel flat bar typically has a thickness of about 3mm to 50mm and a width of 10mm to 300mm.
Steel grade: steel flat bars usually have codes such as SPHC and SS400.
The highlights of the steel flat bar are that it can be bent and has good bearing capacity, with a breaking strength of up to 310N/mm2, a yield strength of up to 210N/mm2, and a relative elongation of 32%.
In addition, flat steel is often galvanized on the outside to help prevent abrasion from acidic environments without worrying about oxidation or rust.
Chemical and mechanical compositio
Application
Steel flat bar is one of the types of steel plates that are widely used in many fields, not only in construction but also in other industries:
- Construction: Used for columns, beams, window frames, steel connectors, and steel structures for construction.
- Mechanics: Production of machine parts and details such as brackets, frames, and cranes.
- Furniture: production of tables, chairs, shelves, and iron items.
- Agriculture: Making net house frames, and protective nets.
- Decoration: Used for making decorative iron railings for houses and other decorative details
Classification of steel flat bar
Steel flat bars are divided into two main types: flexible steel flat bars and rigid steel flat bars.
ductile steel flat bar
A ductile steel flat bar is a type of steel that can be bent at many angles without breaking or deforming. Because of this characteristic, flexible steel flat bars are often used in the production of furniture such as tables and chairs, stair railings, and other items.
hard steel flat bar
Hardened steel flat bar is mainly composed of iron and contain carbon and other chemical elements to increase hardness and tensile strength. Hardened steel flat bar is commonly used for construction works such as roof doors, columns, ceiling structures, and window frames, as well as in the shipbuilding and machine building industries.
Detailed comparison table
| Characteristic | ductile steel flat bar | hard steel flat bar |
|---|---|---|
| Flexibility | Able to bend without breaking. | Does not bend easily. |
| Use | Furniture, stair railings. | Roof doors, columns, window frames, and shipbuilding. |
| Carbon content | Lower. | Higher. |
3 Popular types of steel flat bars on the market today
Black steel flat bars
Black steel flat bars are a popular type of construction steel, widely used due to their low cost and variety of sizes and designs. Black steel flat bars have a black or blue-black surface due to the water spray cooling process.
Electro-galvanized steel flat bars
Electrogalvanized steel flat bars have a layer of paint applied directly to the surface after cleaning, helping to prevent corrosion and increase durability. This type of steel is durable and heat resistant, suitable for projects with harsh climate conditions.
Hot dip galvanized steel flat bars
Hot-dip galvanized steel flat bars are manufactured through a multi-stage process in which the steel is dipped into a bath of molten zinc to create a protective coating against corrosion. This process creates a permanent zinc layer on the steel surface, helping to prevent the formation of rust.
In addition to the above types of steel flat bars, Bao Tin Steel also provides 304 and 316 stainless steel flat bars for readers and customers to take a look.
