product details
product description
What is Hot Rolled Steel Coil A572?
ASTM A572 is a standard for high-strength low-alloy structural steel plates, strips, and sections developed by the American Society for Testing and Materials (ASTM).
Hot-rolled coil is one of its important product forms. It is produced through high-temperature rolling process and has the characteristics of uniform organization, stable performance, high dimensional accuracy, and excellent surface quality.

High-strength low-alloy
A small amount of alloying elements such as niobium and vanadium is added to ordinary carbon steel to significantly improve strength and toughness through fine grain strengthening and precipitation strengthening mechanisms, achieving the design goal of "weight reduction and efficiency improvement".
-
Clear grades
Mainly includes five strength grades: Gr 42, Gr 50, Gr 55, Gr 60, and Gr 65. Among them, Gr 50 and Gr 60 are the most widely used, perfectly covering the strength requirements from medium load to heavy load structures.
-
Weldable and formable
A572 hot rolled steel coil has good welding performance and is suitable for common arc welding, gas shielded welding and other methods. At the same time, its excellent cold bending forming ability meets the processing requirements of complex structural parts.
-
High cost performance
Compared with steels with higher alloy content, A572 provides significant strength improvement while effectively controlling raw material costs, making it an ideal material for projects pursuing economic benefits.
Applications
Building steel structure (core application)
High-rise building frame: Hot rolled coiled steel is used for key load-bearing components such as columns and main beams, and uses its high strength to achieve larger spans and thinner sections, saving space and material costs. For example: A landmark commercial building uses A572 Gr60 main beams, successfully reducing steel consumption by 15%.
Industrial plant: Roof trusses, crane beams, and support systems of large workshops and warehouses bear heavy loads and dynamic loads to ensure structural safety and reliability.
Bridge structure: Hot rolled steel in coil is used for bridge decks, longitudinal beams, cross beams, etc. of small and medium span bridges to meet vehicle load and environmental durability requirements.
Construction machinery and heavy vehicles
Crane boom and chassis: Core structural parts that need to withstand huge bending moments and complex stresses, hot rolled steel coil Astm A572 provides excellent strength support.
Excavator and loader frames: The working environment is harsh, requiring materials with high strength and good fatigue resistance.
Mining dump truck compartment: Withstands ore impact and wear, high-strength steel plates ensure service life. A large mining company uses hrc Astm A572 compartment side panels, which increase service life by 30%.
Agricultural machinery skeleton: Such as harvesters, tractors, etc.
Transportation equipment
Trailer and trailer beams: Carrying the weight of cargo is the key to vehicle safety. A572 Gr 50/55 is widely used.
Container frame: Ensure structural strength to meet stacking and transportation requirements.
Partial ship structure: Such as decks, bulkheads and other non-main hull structures.
Transmission towers and communication towers: Hot rolled steel sheet in coil Astm A572 is used for the main materials and cross arms of towers, etc., requiring the materials to be high in strength, light in weight, and weather-resistant to resist wind loads and ice and snow loads.
Warehouse racking system: Hot rolled steel sheet in coil is used for the columns and beams of heavy-duty racks to carry large tonnage of goods.

Questions ◢
-
-
Q.
Can A572 steel replace Q345B?
A.Yes! The strength of the two is similar, but A572 has better corrosion resistance, especially suitable for export projects or coastal areas.
-
Q.
How long is the delivery cycle of A572 hot-rolled steel?
A.
Conventional specifications are in sufficient stock and can be shipped within 3 days; customized sizes take 15-20 days (taking domestic mainstream suppliers as an example).
-
Q.
How to reduce procurement costs?
A.
Centralized procurement, choose direct supply channels from steel mills, and pay attention to quarterly price fluctuations (it is recommended to avoid the peak season of infrastructure construction).
