| A36 | 3/16" – 18" | 48" – 120" | UP TO 480" |
Benefits of A36 Steel Plate
A36 steel plate is renowned for its excellent machinability, strength, and durability, making it an ideal choice for applications requiring a material that is both relatively lightweight and capable of withstanding high stress. These attributes are particularly important in infrastructure construction, such as buildings and bridges, where structural integrity is paramount to prevent catastrophic failures.
Given its popularity, suppliers like Leeco maintain a robust inventory of A36 steel plates in various sizes, ensuring easy availability. Additionally, A36 is one of the most cost-effective steel plate grades on the market.
Equivalent Grades to A36 Steel Plate
A36 steel adheres to the standards established by ASTM, which are recognized globally for a wide range of projects. However, some countries might necessitate compliance with different regulatory standards for structural projects. For instance, in projects requiring adherence to EN standards, S275 steel is often used as a substitute for A36, as it is generally considered to be equivalent.
While there are no exact matches to A36, other structural grades of mild and high-strength low-alloy (HSLA) steel with similar properties can also be suitable for infrastructure projects. These alternatives provide similar performance characteristics, making them viable options for various construction needs.
Applications and Industries
A36 steel plate is widely utilized in structural applications because of its excellent strength-to-weight ratio and formability. These properties allow it to be easily shaped into various structural components capable of withstanding significant forces. Common infrastructure applications for A36 steel plate include bridge and building construction.
Although it is predominantly used in the infrastructure sector, the versatility of A36 steel plate makes it suitable for a range of other industries, including:
- Construction
- Oil and Gas
- Industrial Manufacturing (particularly for heavy A36 steel plate)
- Road Plate
