The diversity and reliability of flat steel make it an important material for industrial construction

Flat steel, also known as flat bar, is a thin, long Steel Bar, usually with a width ranging from 10mm to 100mm and a thickness ranging from 1mm to 10mm.

It is an important material in many different fields, including construction, machinery, various industrial and civil applications.
Classification of flat steel
There are two common types of flat steel:

Cut steel: Cut from Steel Plates, with a thickness of about 1mm to 10mm.
Hot rolled steel: This product is produced from steel billets and hot rolled into specific sizes. Cross-sections often include sizes such as 20x2mm, 30x3mm, 40x4mm, 50x5mm, etc. In tunnel construction, we often see pipes with sizes such as 60×9, 60×10, 60×16.
Application of flat steel
Due to its durability, excellent load-bearing capacity, corrosion resistance, rust resistance and economy, flat steel is an indispensable choice in various industrial and civil construction projects. Specific applications include:

Used to make galvanized grounding wires, fences, door patterns, etc.
Welded into various mechanical welding products.
Used to make stair guardrails.
Widely used in tunnel construction due to its strength and flexibility.

40×4 flat steel
Among construction materials, 40×4 galvanized hot-rolled flat steel has an important impact with its size of 40mm wide and 4mm thick. Each 6m of 40×4 flat steel weighs 7.56kg, equivalent to 1.26kg per meter. This is not only an ordinary steel, but also attracts attention for its strength and application in many cases.

Advantages of 40×4 flat steel

Hot-dip galvanized 40×4 flat steel is a grounding strip with impressive thickness and width, ensuring strong and reliable in various applications.
Arc welding method is used to connect with the ground rod, which helps to improve stability and save costs compared to other methods such as heat treatment welding or using copper clamps.
With the ability to quickly guide and discharge lightning, this hot-dip galvanized flat steel is an ideal choice for building lightning protection grounding systems.
Widely used in mechanical processing and construction plants.

Versatile applications of 40×4 flat steel

Widely used in mechanical processing and construction plants.
It is an indispensable material in shipbuilding, ensuring the safety and stability of various types of ships.
50×5 flat steel
50×5 galvanized hot-dip flat steel is a steel bar that is immersed in a hot zinc bath at a temperature of 400 degrees Celsius and measures 50mm wide and 5mm thick. This is a high-quality product specially designed to meet the stringent requirements of multiple construction projects.

Technical features of 50×5 flat steel

The thickness of the galvanized 50x5mm flat steel is 5mm and the width is 50mm. The product is immersed in a high-temperature zinc solution to ensure that the coating is strong and durable.
The standard length is 6m or 3m per bar, meeting all the requirements of construction projects.

Outstanding advantages of 50×5 flat steel

This 50×5 galvanized flat steel not only meets the quality standards, but also saves a lot of money compared to choosing other raw materials.
Using the arc welding method, installation and connection become simple and quick.
Good load-bearing capacity, rust and corrosion resistance ensure that your project is safe and stable.
This galvanized steel not only has anti-corrosion and anti-rust properties, but also has the ability to conduct electricity and discharge electricity quickly, protecting building structures from the risk of lightning strikes.
