ZONE'S Cee Section are suitable for any constructruction in which the spans are simply supprted. typical appilcation are single bay building, recessed roofs or alls, tower structures, end walls & building with odd shaped ground plans. where purlins of sufficient length are available. Cee Section may also be used continuously over two or more spans to reduce deflection.

CAPACITY

Thickness: 1.2 ~ 2.0mm [18 gauge ~ 14 gauge]

Length : 15.0m [50'-0"]

ZED SECTION

ZONE'S Zed Section are suitable for multi-bay building which produces a strcuturally continuous line of purlins or girts throughout the length of the building. Structural continuity results in better economy but lapping provides two thicknesses of material over interior supports, increasing the strength og the section where bending moments are critical & improving the load capacity & rigidity of the systems.

CAPACITY

Thickness: 1.2 ~ 2.0mm [18 gauge ~ 14 gauge]

Length : 15.0m [50'-0"]

TOLERANCE

The following tolernces apply to ZONE'S Cee & Zed Section

Depth ± 1mm

Flange Width ± 2mm

Overall length ±5mm

Hole center ±1.5mm

1Camber : up to 1 in 500 depending on length

2Bow : up to 1 in 250 depending on length.

1Camber is the variation from straightness in the plane of the web.

2Bow is the variation from straightness in the plane perpendicular to the web.

CEE & ZED Sections used as purlins or girds in three structural configuration

a. As simple spans-for both Cee & Zed Sections.

b. As double spans-for both Cee & Zed Sections continuous over the center support.

c. As continuous spans-limited to Zed section lapped over each internal support.
