****** Grade 40 can be produced in the following sizes: ## 3, 4, 5, 6, [10; 15; 20]
******* Grade 40 can be produced in the following sizes: ## 3[10], 4[13], 5[16], 6[18]
******** if required, we can produce rebars of non-weldable quality RB300, RB400
*********if required, we can produce rebars to ASTM A706/A706M-96
********** Numerator is the angle of a bend and denominator is the angle of a rebend after mechanical ageing
We can also produce weldable quality steel reinforcing bars (with tensile strength of 400 and 500 N/mm2) as per Portuguese and Finnish standards.
