The Art Of Cladding
Use the dimension and character of CGI Mini to sculpt a masterpiece
CGI Mini is popular for domestic use, and has also gained popularity within the interior design and shop fitting industry where its interesting profile can be used to great effect.
CGI Mini sheeting is available unpainted, or a wide range of single and double sided, pre-painted colours are available to compliment any colour scheme.

Cladding with Form and Function
The low corrugated ribs that form the CGI Mini cladding profile have a height of only 6mm, which enhances the materials visual appeal when it is used against flashing or capping. This low rib height also allows CGI Mini sheeting to have an 825mm coverage, which reduces the number of sheets that you need to install, and provides greater economy.
CGI Mini steel sheets have a maximum length of 6000mm and can be custom cut to suit your requirements. For information about minimum lengths and availability, please contact Stratco. CGI Mini cladding has a zinc/al coating, and you can choose from three base metal thicknesses of .35mm, .42mm and .48mm. Each thickness has different spanning capabilities. CGI Mini has a material designation of AS 1397/G550 AZ150 (550 MPa minimum yield stress, 150g/m² minimum coating mass). Pre-painted steel complies with AS/NZS 2728:1997.
Typical Applications
CGI Mini is an ideal material for walling applications, as well as a wide variety of internal applications. CGI Mini cladding is often used for ceiling work, because it can be easily transported and installed, and requires only a simple angled flashing to provide a clean, professional finish. This made CGI Mini a common material at the turn of the last century. While the product is still popular with renovators of older homes, these days, many architects and home owners are looking for something different.
The simple, stylish look of CGI Mini steel sheeting, combined with today's modern colours, makes it an ideal solution for designers and owners with flair and imagination. Internal walls are brought to life with CGI Mini; interesting effects can be achieved when the panels are run at different angles, creating new textures of light and shade. CGI Mini is not suitable for roofing due to its low rib height. Entry of water through the side laps may also be possible.
CGI Mini sheeting allows the designer to add a stylised surface that is full of character with very little effort. It can be found applied to panelling, artwork, indoor furniture, fencing, as a cladding to enhance the face of a bar, and in both domestic and commercial settings. Used internally it is strong, has an excellent lifespan, and is easily applied with special ripple self drilling and tapping screws.

Installation Information
It is best to use at least two people when installing. Ensure the supporting structure is as rigid and flat as possible. Sheets should be overlapped by a minimum of one and a half corrugations. For aesthetic purposes it is recommended that the support spacings comply with the table below. When installing CGI Mini, extra care must be paid to ensure a uniform and even finish is achieved.
When installing on a wall, the sheets may be placed with the corrugations running vertically, horizontally, or at an angle. Fasteners should be spaced in accordance with the maximum spans found in the 'Maximum Spans' table, and the fixing recommendations below. The sheet should be fixed to all battens and studs that make contact with it, to prevent any noise created when the sheets flex from pressure changes in the building. CGI Mini is best installed using ripple self drilling screws. These screws have a small head, which have been specifically designed to suit this product, and types to suit both timber and steel are available.

Installing CGI Mini Cladding
To install CGI Mini work out how many sheets are required to cover the area, ensuring that the sheets are overlapped with equal spacings. Begin fixing the sheet at the centre of one edge and work out toward the other end of the sheet. Place each row of fasteners parallel with the first row. If the sheet is 3000mm long or over, be careful to ensure the sheet remains straight along its top and bottom edge. When installing the screws, do not flatten the corrugations through excessive force, as this will make the sheet wider, and therefore effect your measurements. End laps are not recommended for aesthetics, but they are possible if required. CGI Mini may be spring curved to a radius as low as 2000mm. However, it is recommended that the support spacings be reduced to the equivalent of single spans for radii of 6000mm or less, refer to the table below.

Maintenance
The performance of CGI Mini over time is dependant on the correct application of the product as outlined in this brochure, on correct product selection, and on maintenance suitable for the environment in which the product is to perform. It is important that screws have the same life expectancy as the CGI Mini sheeting.
The use of CGI Mini should comply with the specifications set out in SAA HB39-1997 'Installations code for metal roofing and wall cladding' published by Standards Australia, and users should first acquaint themselves with this publication. It is recommended that this information is read with the 'Selection, Use and Maintenance' brochure.
