Place the steaks in a large shallow container with a lid. Season each side of the steaks with the salt and lemon pepper. Gently pour the beer over the steaks (making sure the seasoning doesn't wash off). Cover and refrigerate for 1 to 2 hours.
Preheat barbecue for high heat.
Lightly oil barbecue grate. Place steaks on barbecue and discard beer marinade.
Cook for 5 minutes per side or until cooked to your tastes.
