1 Z and C Purlins

2 General data The "Z"- and "C" (Zed and Cee) shaped sections of KAMARIDIS SA are accurately roll-formed via cold forming from high-strength zinc-alloy coated steel in order to provide an efficient, lightweight and cost efficient roofing, cladding and walling support system, for framed structures. (Purling and girt system) Applications The KAMARIDIS SA "Z" shaped section may be used over single spans, unlapped continuous spans and lapped continuous spans in multi-bay buildings. Lapped spans result in a considerable load bearing capacity increase in the system. The KAMARIDIS SA "C" shaped section may be used over single spans and unlapped continuous spans in multi-bay buildings. They are ideal as eave purlins or where compact sections are required. The "C" shaped section cannot be used in overlapping structures. Range of products and services The wide range of the services KAMARIDIS SA offers includes: The full range of "Æ"- êáé "C"-shaped profiles Technical information for cleatless connections Bolting systems to suit all project requirements Corrosion protection warranty Technical advice on improving the life expectancy of purling systems in corrosive environments Access to a network of experienced engineers

This means that we can use sections of minimum thickness and weight, resulting in reduction of the time and the cost of the construction. They are classified as "thin gauge member" profiles and the study as well as the analysis concerning their application is conducted according to the provisions of the European standard EN : "Eurocode 3: Design of steel structures. Part 1.3: General rules. Supplementary rules for coldformed thin gauge member and sheeting"

(For further details, consult the section regarding the technical characteristics of the sheeting) Corrosion protection In standard production the material used is hot-dipped galvanized, type Z275, zinc-alloy coated (with a minimum coating density of 275 gr/m 2 ) steel (according to AS & EN ). Upon request, purlins can also be manufactured from hotdipped galvanized, type Z350, zinc-alloy coated (with a minimum coating density of 350 gr/m 2 ) steel, for applications in aggressive and severely corrosive environments.

5 Æ - shaped profiles The "Z" shaped sections structural elements of KAMARIDIS SA feature two flanges of different width so that two elements with the same static height can overlap, fitting perfectly to each other. In this way, we achieve to bridge multiple spans with continuous purlins. This purlin fixing method is called continuous and provides the advantage of practically doubling the purlin thickness at its fixing points, where bending moments and shear forces have maximum values, thus improving the load bearing capacity as well as the rigidity of the system. The structural elements of "Z" profiles with the same static height but different thickness can be overlapped in any combination. Other fixing methods: A) Sleeve system B) Freely supported continuous fixing C shaped sections The "C" shaped sections structural elements of KAMARIDIS SA feature two equally sized flanges and are ideal for use as purlins, girts as well as door and window frames. They cannot be overlapped and they are only installed freely supported over single spans or continuous spans with the ends butted. Kamcurve purlins Kamcurve purlins are the solution that KAMARIDIS SA exclusively provides wherever curved purlins or girts are required. They are formed from "C"-section elements of KAMARIDIS SA, which are curved in the web plane. The Kamcurve purlins are intended to facilitate the architectural design. Availability The structures including Kamcurve purlins may be partially limited by the length of the "C"-section elements, from which these purlins are formed, as well as by the transportation of items of high radius of curvature. In some cases, it may be necessary to use two or more Kamcurve purlins.
