48 quadrupole magnets have been manufactured in this present work for the SRRC storage ring. Four families of quadrupole magnets with various magnetic lengths are used in the storage ring. The same pole contour with a bore diameter of 76 mm is computed via the ``MAGNET`` program. The magnet design and procedure of mechanical fabrication and assembly are also described. The auxiliary coils are incorporated in the main coils for trimming the field strength of each individual magnet. Pole tip ends have a 6 mm x 6 mm chamber so as to reduce the dodecapole in the end of magnet. Field mapping results having achieved the deviation of integral quadrupole field within {plus_minus}1 {times} 10{sup {minus}3} in a 30 mm bore radius region is also confirmed.
