what is the difference between EN39 S235GT and Q235 ?

EN39 S235GT and Q235 are both steel grades used for construction purposes.

EN39 S235GT is a European standard steel grade that refers to the chemical composition and mechanical properties of the steel. It contains Max. 0.2% carbon, 1.40% manganese, 0.040% phosphorus, 0.045% sulfur, and less than 0.020% Al. The ultimate tensile strength of EN39 S235GT is 340-520 MPa.

Q235, on the other hand, is a Chinese standard steel grade. It is equivalent to EN standard S235JR steel grade which is commonly used in Europe. Q235 steel has a carbon content of 0.14%-0.22%, a manganese content of less than 1.4%, a phosphorus content of 0.035%, a sulfur content of 0.04%, and a silicon content of 0.12%. The ultimate tensile strength of Q235 is 370-500 MPa.

In summary, EN39 S235GT and Q235 have similar chemical compositions but slightly different mechanical properties. The choice between the two depends on the specific application and requirements of the project.
