  • Purlins should be stored off the ground (to avoid getting wet) and on a slight slope so that water can be drained away.
  • Direct contact of incompatible material should be avoided. In such applications, suitable paint systems should be obtained from paint manufacturers.
  • Special transport requirements are needed for length over 12m.
