Testing
Stramit® Flashings are coated with Zinc-Aluminium / Zinc-Aluminium-Magnesium alloy and COLORBOND® steel will give excellent durability in almost all locations more than 200m from a marine environment or in some light industrial applications.
Applications close to industrial or unusually corrosive environments will need to be individually assessed for durability. For these and installations closer to the coastline, please contact your nearest Stramit office for advice. External brackets for Stramit® Flashings should only be used in benign locations.
Stramit® Flashings should only be used with Stramit rainwater products.
Stramit rainwater products should be handled with care at all times to preserve the product capabilities and quality of the finish. Packs should always be kept dry and stored above ground level while on site.
If the products become wet, they should be separated, wiped and placed in the open to promote drying.
Stramit® Flashings are supplied cut to length at most of our offices. Contact your local Stramit office or refer to the Stramit Product and Service Guide for your area for further detail.
Under the Environmental Planning and Assessment Act 1979 and its regulations, all building work must be carried out in accordance with the Building Code of Australia (BCA), now part of the National Construction Code (NCC).
In addition to referring to Australian Standards AS/NZS 3500.3, and AS/NZS 3500.5, the BCA also contains requirements for the disposal of surface water in Volume One, Performance Requirements FP1.2 and FP 1.3, and in Volume Two, Part 3.5.2, namely, Performance Requirement P2.2.1 and Clauses 3.5.2.1. to 3.5.2.5.
The most common means of satisfying these requirements for roof drainage (i.e. guttering) installations is by complying with the National Plumbing and Drainage Code AS/NZS 3500.3. Furthermore, in each state and territory it is necessary to satisfy the relevant regulations.
Stramit's Rainwater products are protected in Australia by registered designs.
All Stramit rainwater products confirm with, or are equivalent to, AS/NZS 2179.1.
Stramit has in-house, purpose built testing equipment used to design, develop and improve products for the Australian market.
Many of our products are tested or witnessed by independent organisations. These include University of Technology, Sydney; James Cook University Cyclone Testing Station; The University of Sydney; and CSIRO.
The ongoing research and development activity ensure we remain at the forefront of innovation, design and consumer information.
Technical Information
The flashing shall be [insert Stramit Fascia type] as selected based on size and performance. Material shall be protected steel sheet to Australian Standard AS1397 with a minimum yield stress of 300MPa and an AM100/AZ150 coating with an oven-baked paint film of selected colour, or a plain AM125/AZ150 coating.
All accessories are to be fully compatible as recommended by the manufacturer. The product and its accessories shall be installed strictly in accordance with the manufacturer's recommendations. Flashings and all adjacent products shall be supplied in compatible materials as specified.
All work shall be fixed in a workman like manner, leaving the job clean and weather tight. All debris (screws, rivets, cuttings and filings, etc) shall be cleaned off daily. Repair all minor blemishes with touch up paint supplied by the manufacturer.
Note: Some products are supplied in 300MPa steel with galvanised Z275 coating.
In the design and detailing of a roof drainage system, consideration must be given to a range of factors.
These include:
- rainfall intensity
- roof catchment area
- gutter size/capacity, falls and outlets (sumps, rainwater heads, nozzles)
- downpipes (size, quantity and placement)
- overflow consideration
- material selection, and
- jointing.
All fastening screws must conform to AS3566 – Class 3.
Drainage from copper or lead products (including roof flashings) should not be allowed to discharge on to zinc/aluminium or aluminium/zinc/magnesium alloy or COLORBOND® steel components. Similarly, lead or copper components should not be installed in contact with zinc/aluminium or aluminium/zinc/magnesium alloy coated steel. Each of these combinations will lead to premature corrosion.
Drainage from copper, COLORBOND® and zinc/aluminium or aluminium/zinc/magnesium alloy coated steel, translucent (or other inert material) should not be allowed to discharge onto, or into, galvanised products.
Stramit's rainwater products are manufactured from G550 and G300 Zinc Aluminium or Zinc Aluminium Magnesium coated steel (AZ150/AM125) or galvanized (Z275) in accordance with AS1397, and COLORBOND® steel with a coating conforming to AS2728.
Other coatings, grades and materials may be available, subject to enquiry.

Installation Information
Stramit's rainwater products can be easily cut, where required, using a fine-toothed hacksaw and tin snips. Please dispose of any off-cuts carefully.
While there may be variations between states, contractors who install guttering systems are generally required to hold an appropriate licence. The work is required to comply with the appropriate codes and standards. Statutory warranties normally apply and consumers have a right to lodge a complaint with the appropriate authority.
During the installation of the roof drainage system, particular attention should be given to the following:
- The use of compatible materials for drainage system components, leaf-guard system components and fasteners/sealants to connect and seal the components.
- The position of the gutter in relation to the fascia.
- Installation of the specified gutter and downpipes, and ensuring that downpipes are installed in the correct locations and numbers.
- Gutter fall, ensuring sufficient fall in the direction of the downpipes.
- Overflow must be allowed for and specific components installed where required.
- All debris and loose waste materials (swarf, fasteners, etc.) must be cleaned off at the end of each day and at the completion of the installation, to prevent blockages of the drainage system or deterioration of the individual components, and
- Any protective films should also be removed as part of the installation process.
Stramit recommends installers follow the installation code for metal roofing and wall cladding as outlined in the Standard Australia Handbook - HB39.
Stramit's rainwater products are available in COLORBOND® steel colours. However should painting of Zinc Aluminium / Zinc Aluminium Magnesium coated steel products be required, use the following procedure.
A weathering period of two weeks following installation will make painting easier. Clean the rainwater product immediately prior to painting. Dirt can be washed off using water with mild detergent. Any grease marks should be wiped away with paint thinners.
In benign locations good quality acrylic paint will give satisfactory performance. First use a low-gloss water-borne acrylic primer. Finish with water-borne acrylic gloss, or your choice of gloss level.
Use only neutral-cure silicone for sealing joints when using Stramit's rainwater products. Take care to avoid pockets in joints which may hold moisture and potentially reduce durability.
Consideration should be given to handling and installation issues as part of site induction safety procedures. Specific consideration should be given to pack handling , avoidance of cuts, trips, slips and falls, long section handling, particularly in windy conditions, section cutting procedures and surface temperature on sunny days.
Personal Protection Equipment (PPE) should always be used, including cut resistant or leather gloves when handling and transporting product and appropriate footwear when handling long lengths.
Stramit's rainwater products manufactured in the COLORBOND® range of colours are supplied with a protective strippable coating. This should be removed at the last possible stage during the installation process.
It is possible to selectively move the coating to one side to avoid fastenings and joints before finally remove the coating from the installed product. Do not leave the products with strippable coating intact exposed to direct sunlight for more than a week or it can become difficult to remove.
Stramit rainwater products can benefit from occasional washing if they're not flushed out regularly. These areas include portions of fascia and the underside of accompanying gutters. Clean frequently and remove overhanging vegetation. Following a regular and adequate maintenance regime is also a requirement for your warranty.
