Available in cross-section heights from 100 to 350mm and thicknesses from 1.5mm to 3.2mm to meet different aperture and design requirements.
Purlin bracing system
Number of bracing rows in each span: depends on purlin span and load. The number of bracing rows can be 0, 1, 2 and 3. At least one row of bracing should be used in each span and the spacing between bracing rows should not exceed 20 times the section height.
Standard punch details
Bolt holes are drilled at the attachment position to the cipher plate, the overlap position and at the bracing points.
For 300 and 350 purlin bellies, centerline holes can be pre-drilled upon request. They can be combined with holes in the ciphertext to create a 3-bolt connection to the ciphertext.
