Various preparations before construction of color steel sandwich panel manufacturers: all preparations shall be made in advance before nailing of color steel sandwich panels. Check purlin specifications and paving specifications: check whether purlin paving specifications, spacing and inclination meet the overall design requirements. In addition to the purlin support points on the top of each top plate, one or two purlins shall be set in the middle.
