Ready-mixG40
G40
A higher-strength class for elements designed at G40. Suitability comes from the specification, not from this page.
Often requested for
- Structural members specified as G40
- Higher-load elements on the drawing
- Jobs where a lower grade would not match the design
The number in a grade such as G30 is commonly treated as the strength class in N/mm². That is industry naming, not a T3 test result. Your engineer specifies the grade. T3 confirms what can be supplied when quoting. This page is not an engineering design.
