ASTM A36/A36M A36 Introduce
ASTM A36/A36M is a steel standard developed by the American Society for Testing and Materials (ASTM). The standard specifies the requirements for the material, design, and manufacture of structural steel shapes, plates, and bars that commonly used in construction works. ASTM A36/A36M is one of the most popular and commonly used structural steel standards in the world. It has a wide range of applications, ranging from bridges and buildings to heavy construction equipment, oil rigs, ships, and power plants.
