We construct full broadband models in an analysis of Suzaku observations of nearby Seyfert 1 AGN ( z \leq 0.2 ) with exposures > 50 ks and with greater than 30000 counts in order to study their iron line profiles .
This results in a sample of 46 objects and 84 observations .
After a full modelling of the broadband Suzaku and Swift -BAT data ( 0.6-100 keV ) we find complex warm absorption is present in 59 \% of the objects in this sample which has a significant bearing upon the derived Fe K region parameters .
Meanwhile 35 \% of the 46 objects require some degree of high column density partial coverer in order to fully model the hard X-ray spectrum .
We also find that a large number of the objects in the sample ( 22 \% ) require high velocity , high ionization outflows in the Fe K region resulting from Fe XXV and Fe XXVI .
A further four AGN feature highly ionized Fe K absorbers consistent with zero outflow velocity , making a total of 14/46 ( 30 \% ) AGN in this sample showing evidence for statistically significant absorption in the Fe K region .

Narrow Fe K \alpha emission from distant material at 6.4 keV is found to be almost ubiquitous in these AGN .
Examining the 6-7 keV Fe K region we note that narrow emission lines originating from Fe XXV at 6.63-6.70 keV and from Fe XXVI at 6.97 keV are present in 52 \% and 39 \% of objects respectively .

Our results suggest statistically significant relativistic Fe K \alpha emission is detected in 23 of 46 objects ( 50 \% ) at > 99.5 \% confidence , measuring an average emissivity index of q = 2.4 \pm 0.1 and equivalent width EW = 96 \pm 10 eV using the relline model .
When parameterised with a Gaussian we find an average line energy of 6.32 \pm 0.04 keV , \sigma _ { width } = 0.470 \pm 0.05 ¤ keV and EW = 97 \pm 19 eV .
Where we can place constraints upon the black hole spin parameter a , we do not require a maximally spinning black hole in all cases .
