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.

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.

condition that design, installation and use comply with

the specifications and the instructions provided by the

company.

Material specifications - standards

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 1993-1.3:

The "Z" and "C" shaped section structural elements are manufactured through cold forming procedure

from zinc-alloy coated steel Zinc-hi-ten® which minimum yield stress is by 60% higher than the

respective profiles formed through hot forming. This means that we can use sections of minimum

thickness and weight, resulting in reduction of the time and the cost of the construction.

density of 275 gr/m2) steel (according to AS 1937-93 &

EN 10147-100).

Upon request, purlins can also be manufactured from hot-

dipped galvanized, type Z350, zinc-alloy coated (with a mini-

mum coating density of 350 gr/m2) steel, for applications in

aggressive and severely corrosive environments.

Steel Quality: G450 (according to AS 1397-93) or S450GD (according to EN 10147-2000) with

guaranteed minimum yield stress of 450 N/mm2.

Æ and C 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 ele-

ments, 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.

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.

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
