Description

Brownbuilt was the first Concealed Fix roofing profile in South Africa. Brownbuilt is a concealed fix profile, with a cover width of 406mm, providing the architect with an aesthetically pleasing appearance with 90 degree standing seams, offering a watertight roofing solution.

The Profile

The profile shall have three standing ribs at 203 mm centres giving a nett cover of 406 mm. The rib height shall be 48 mm and provide capillary breaks. Each pan shall incorporate two stiffener ribs.

Assembly

It is recommended that Brownbuilt™ sheeting be laid by an approved contractor in strict accordance with manufacturers specifications. When using a GRS (Brownbuilt) Approved Contractor, a five year guarantee of site-workmanship and watertightness can be issued after approval by Global Roofing Solutions (Pty) Ltd.

Brownbuilt Roof Sheeting Building

Flashing

Stop endings must be formed at the apex and the pan turned down at the eaves to form a drip. The roof sheeting shall be closed as necessary with purpose made flashings of a design approved by the supplier. These flashings shall be notched around ribs where necessary and fixed on S1 clips. All these operations must be performed with special tools available from the supplier.

Site handling

All Brownbuilt™ materials should be suitably supported under cover until required to be hoisted into final position.

Cleaning up

The completed roofing, including gutters, must be handed over free of any swarf and other debris.

Quality assurance

The manufacturer shall be assessed and certified as complying with ISO 9001:2008 Quality Management System.

Translucent Sheeting

The Brownbuilt™ profile is available in Fibreglass (GRP) on special request.

Note Brownbuilt™ is readily available in galvanised steel and the following Chromadek colours – Fish Eagle White, Dove Grey and Dark Dolphin. Other materials and colour coatings listed above, are on inquiry only and may incur longer lead times.

Sheet lengths

Available ex-factory in sheet lengths limited only by transport restrictions, normal loads 12.5 m and abnormal loads 18.6 m. Longer lengths can be milled on site, obviating end laps which are not recommended on low pitch lengths. End lapping negates the concealed fix concept and no water tightness guarantee can be given. End lapping also reduces the life expectancy of the roof, due to corrosion. NOTE: When using cranked sheets consideration for road transport has to be taken into account. Refer to the GRS Installation Manual for detailed dimensions and fixing instructions.
