Introduction to the yield strength of commonly used materials for guardrail beam

In the previous FAQ, we learned about the commonly used material standards for guardrail beams. There is an important mechanical property measurement factor for the material of guardrail beams, that is, the size of the yield strength, which is also an important factor for customers to check whether the guardrail beams meet the quality requirements. reference factor.

Yield strength: It is the yield limit of a metal material when it yields, that is, the stress that resists a small amount of plastic deformation.

S235JR and S355JR yield strength reference:

Material S235JR S355JR
Yield Strength ≥235Mpa ≥355Mpa
