Hi Eddie, thanks for writing in. This includes the extruded aluminum construction and can be seen in the submittal sheet: https://s3.amazonaws.com/s3.supplyhouse.com/product_files/Hart-Cooley-0F0061-Submittal-Drawing.pdf
No, the louvers on this grille unit are fixed and the airflow is not adjustable.
They are listed width x height. You would need a 30" x 20" in the case you describe.
