Overview of UNE 36011 Standard for Non-Alloy Structural Steels

UNE 36011 is a Spanish standard that specifies technical requirements for non-alloy structural steels used in construction and general engineering. The standard includes different grades based on mechanical strength and intended application.

UNE 36011 is commonly used for steel plates, beams, and profiles in welded or bolted structures. It defines requirements for chemical composition, tensile strength, yield strength, elongation, and impact resistance.

The most well-known grades under UNE 36011 are F.110, F.210, and F.310, which are comparable to international grades like EN 10025 S235JR or ASTM A36 depending on the mechanical requirements.

This standard plays a key role in ensuring structural safety and material uniformity in civil engineering projects, machinery manufacturing, and pressure equipment.
