Preheat an outdoor grill for high heat, and lightly oil the grate. Stir the salt, paprika, black pepper, onion powder, garlic powder, cayenne pepper, coriander, and turmeric together in a small bowl; set aside.
Rub the steaks on all sides with the seasoning mixture. Cook on the preheated grill to your desired degree of doneness, 3 to 3 1/2 minutes per side for medium-rare. An instant-read thermometer inserted into the center should read 130 degrees F (54 degrees C).
