Prepare a grill or grill pan for medium-high heat.
Put the steaks on a platter and brush one side with half of the melted butter. Sprinkle on half of the seasoned salt, lemon and pepper seasoning and garlic salt.
Grill the steaks seasoning-side down for 2 minutes. Brush the top side with the remaining butter and sprinkle on the remaining seasoned salt, lemon and pepper seasoning and garlic salt. Flip the steaks and cook on the other side for 2 minutes for rare. (For medium-rare, cook 3 minutes per side.) Remove to a platter and rest for 5 minutes before serving.
