Shaped fittings, such as elbows, crosses, and tees, are stamped MM for metric tubing and have no step on the forging . The Starrett Steel rule is the basic measuring tool from which many other tools have been developed. The cover for the reinforcement to meet specified period of fire resistance is detailed as follows: Cover in excess of 40 mm (1.57 inch) may require additional measure to reduce risk of spalling. Where the thickness of the section exceeds fifteen (15) inches (380 mm), a thickness of fifteen (15) inches (380 mm) should be used in determining the temperature or minimum reinforcement. The minimum amount of steel reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings.
