Sirloin Steak Cooking Time Chart:
For the best results, cook steaks using an accurate Meat Thermometer instead of a timetable. Steaks should be allowed to rest up to 10 minutes before serving. This resting period allows the juiced to distribute in the meat. Keep in mind that your meat will continue to cook while it is resting, so adjust grilling times accordingly (temperature of meat can raise up to 10 degrees).
