ASTM A36 vs S235JR Steel | Structural Steel Grade Comparison
ASTM A36 and S235JR are two of the most commonly used structural steel grades in construction, fabrication, and engineering industries. Although both steels serve similar structural purposes, they belong to different international standards.
ASTM A36 is defined by ASTM International standards, commonly used in North America and many international engineering projects.
S235JR is produced according to EN 10025-2 European standards and is widely used across Europe, Asia, and global engineering markets.
Both steel grades provide reliable structural strength and good weldability, making them suitable for construction frameworks, machinery structures, industrial platforms, and fabrication projects.
Understanding the differences between these steels helps engineers and procurement teams select the most appropriate material based on project standards and structural requirements.
