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.
Under the Environmental Planning and Assessment Act 1979 and its regulations, all building work must be carried out in accordance with the Build Code of Australia (BCA), now part of the National Construction Code (NCC).
In addition to referring to Australian Standard AS/NZS 3500.3, the NCC also contains requirements for the disposal of surface water in Volume One, Performance Requirements FP1.2 and FP1.3, and in Volume Two, Part 3.5.3, namely, Performance Requirement P2.2.1 and Clauses 184.108.40.206. to 220.127.116.11.
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.
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.
In the design and detailing of a roof drainage system, consideration must be given to a range of factors.
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.
The brackets need to be installed at a maximum spacing of 1000mm.
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.
All fastening screws must conform to AS3566 – Class 3.
For fixing Stramit® Commercial Eaves Gutter brackets to steel purlins (1.5mm) – No. 12-14 x 20mm hex-head self-drilling & threading screws.
For fixing Stramit® Commercial Eaves gutter brackets to timber – No. 12-11 x 25mm type 17 hex-head self-drilling screws.
For lap joints and accessories – 3.2mm diameter aluminium pop rivets.
The brackets must be attached with a minimum of two screws in each bracket in a diagonally opposed way.
The Stramit® Commercial Eaves Gutter has a few specific installation requirements that differ from our other Rainwater Products.
The Stramit® Commercial Eaves Gutter brackets should be installed directly onto a purlin with a BMT of no less than 1.5mm, or an equivalent timber fascia.
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:
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.
