Wall Abutment/Internal Corner Flashings
We supply wall abutment/internal corner flashings at 3m lengths in a range of sizes. Internal angles are specified at point of order (The most popular internal angle we supply is 90° but we can fold to any angle at no extra charge). We can also make the legs to custom sizes if the size you require is not listed.
Wall abutments/internal corners are available in 0.7mm gauge with welted edges to give extra strength and stability.
Available in a wide range of sizes, colours and angles
Description
The internal angle of the flashings can be specified to match your roof pitch. To calulate your required angle simply minus your roof pitch from 90°. (e.g. if your roof pitch is 15° you will require an internal angle of 75° (90-15)
Angle ranges are 45° to 90
Eaves flashings are available in 0.7mm gauge with welted edges to give extra strength and stability.
Galvanised
Galvanised sheeting is a high quality hot dipped zinc coated steel with no additional finishes added.

*Recommendations for period to first maintenance are based on the premise that the strength and integrity of sheets would diminish after the period specified, unless maintenance was carried out. The periods estimated are based on a theoretical weight loss as a result of natural weathering under test conditions. All figures are estimates and do not constitute a guarantee period.
Please be aware that galvanised products have a shorter expected lifespan than coated products. We would recommend that galvanised products are not used within 3 miles of the coast as the lifespan can be significantly reduced.
