Description

Colour Clad Profiles manufacture  Z Purlins and C Section in both 1.6mm thick and 2mm thick galvanised steel, designed for supporting either roof sheets or vertical wall cladding, they can also be used in conjunction with our built up system. We can manufacture our Z Purlins at 140mm, 175mm and 200mm depths. Our state of the art manufacturing equipment allows us to comfortably manufacture lengths up-to 10m.

Z  Purlins are light gauge steel sections/rails/mezzanine floor components for agricultural, industrial and commercial projects. Purlins are integral to the stability of the structure connecting rafters/beams from 800mm to 10M bays.

Z Purlins (roof) or side rails (walls) can be connected using a sleeved or butted system.

Sleeved

This system is used on a building with 3 or more bays.

The sleeve sits on the cleat and connects two Z Purlins on one plate.

This adds to the strength and rigidity of the structure.

Butted

This system is used when the structure has small spans or light loadings. It is also used when the application does not allow the use of a sleeve, eg within the web of the rafter.

Colour Clad Profile's steel sections have all been tested and designed to meet the BS & European Standards.

At Colour Clad Profiles Ltd we have a full range of standard sections for all of your new build projects. We also have the ability to match existing designs for refurbishments or extensions. 

Z & C Section Accessories 

Sag bars

Connected between the purlins to avoid the purlin twisting mid bay. Also hold the button flange in place under uplift conditions.

Rolled from galvanised steel to the exact measurement required to ensure an accurate application.

Apex Ties

A small section designed to hold the top two roof purlins in line and tie up both sides of the slope together.

Diagonal Wire Ties

Used in horizontal application (side rails), in conjunction with side rail, supports to hold the sections level.

There are 3 basic applications of Diagonal wires ties

Mid Bay Support System
Split Bay Support System
Part Bay Support System

Bolted to the cleats on the column then together under the side rail support at the centre bay.

Generally used on bays ranging in size from 4.5M to 6M

Spilt Bay Support System

Used on bays over 6.1M to 9M

Two side rail supports to add additional strength and support side rails.

Wire Ties fixed to cleats on the column, and to the underside of side rail support.

Part Bay Support System

Similar to the Mid Bay Support System, but in this case only half of the bay needs to be supported as there is a door post to the side.

Side Rail Supports

Galvanised support bars designed to add stability to side rails.

They are used in conjunction with diagonal wire ties to ensure that the rails remain level while adding stability against wind pressure or suction loads.

All holes in the cleat of section are designed to connect the side rail holes.

Eaves Beam to side rail supports.

Galvanised support bar joining the underside of the Eaves beam to the side rails. Bolted the same way at the side rail supports.

Eaves Ties

Galvanised bafe tying the eaves beam to the first Z Purlin up the slope.

The cleat connected to the eaves beam is at an angle (due to the pitch of the roof) so it will pick up the z-purlin up the slope.

Bolted to the face of both the eaves beam and the Purlin it holds the sections level and strong.
