EnvioSeries pre-finished steel combines outstanding performance with unrivalled reliability and impressive sustainability credentials.
The result of sustained evolution and revolutionary coating technology, the best product just got even better.
Warranty – Peace Of Mind
The warranty offered is most comprehensive guaranteed up to 30 years for pre-finished steel products. Dramatic and unrivalled improvements in colour stability and gloss retention are translated into a durable product with greater longevity.
The warranty guarantee is directly with the building owner meaning that in the case of a claim the contact with ASTEEL is direct rather than having to go through the supply chain, saving time, money and unnecessary responsibility avoidance by any parties.
Composite steel/polymer sheets forming a sandwich structure offer a compact solution that also provides the roof with sound insulation properties.They reduce the impact noise from rain or hail, ensuring a highest standard of interior comfort.
If nestable profiles become wet while closely stacked, formation of wet storage stain or “white rust” is inevitable.
To minimise the possibility of inadvertent damage:
a) Inspect deliveries on arrival. If moisture is present, individual sheets should be dried immediately with a clean rag and then stacked to allow air to circulate and complete the drying process.
b) Well ventilated storage is essential. Always store metal products under cover in clean, well ventilated buildings.
c) Cross stack or fillet sheets where outside storage in unavoidable and make provision for a fall to allow water to run off. Cover the sheets.
It is the responsibilities of the roofing contractor to avoid damaging the roof sheeting during its installation and fixing. Never drag sheets from pile. Remove by ‘turning off’ the stack. Lift sheets onto a roof, and do not drag over the eaves or the purlins. Use clean footwear. Remove swarf and other contaminants regularly.
1. Safety Precaution
Impose highest safety awareness, protecting all parties from accident. Provide adequate personal protective equipment (PPE), fall arrestment tools and perimeter guardrails. Strictly adhere to all laws and practices that apply to your site.
2. Fixing to Support
Aidyl Roof profile is pierce-fixed to timber or steel supports. This means that fastener screws pass through the sheeting. You can place fasteners for Aidyl Roof through the crests or in the pans. To maximise water tightness, always place roof fasteners through the crests. For walling, you may use either crest or valley-fixing. Always drive the fasteners perpendicular to the sheeting, and in the centre of the rib. Don’t place fasteners less than 25mm from the ends of sheets.
3. Side Lapping.
The side of Aidyl Roof with the anti-capillary groove is always the underlap. If end lapping is required, seek advice from our technical team on the sequence of laying and amount of overlap.
4. Check Alignment Periodically
Occasionally check that the sheets are still parallel with the first sheet, by taking two measurements across the width of the fixed sheeting.The string line can be used to ensure that the end of the roofing sheets is in line.
5. Turning Up and Clean Up
On all roofing less than 15°, the high end of all sheets must be turned up to stop water from being driven under the flashing and into the building.
6. Cutting and Sealed Joints.
For cutting thin metal on site, we recommend cold cutting such as metal scissors or nibbler because it produces fewer damaging hot metal particles. Cut materials over the ground and not over the other materials. For sealed joints use screw or rivets and neutral-cure silicone sealant as suitable for use with TitanZinc, GaluZinc and Pre-finished Steel
General Note: Oil Canning
Oil canning is an aesthetic issue, not a structural problem or a defect . It is unrealistic to expect any architectural roof or similar wide-metal element to be totally free of some degree of oil canning. While oil canning cannot be totally eliminated, adherence to industry acceptance and recognized methods of design, metal specification, handling, fabrication, and installation can minimize its occurrence. Carefully attention to the causes of oil canning within all the phases of design and construction is the most effective way to reduce its occurrence.
