Barge Capping Trimdek 75mm Zincalume
This Zincalume barge capping is shaped for Trimdek sheet profiles, sealing the gable edge where the sheet meets the barge board. The 75mm rise sits over the Trimdek ribs and carries the waterline clear of the sheet edge, giving the gable a finished, watertight look in an unpainted aluminium-zinc finish. It is made from 0.55mm BMT Zincalume steel, cut to length with a +200mm / -0mm tolerance, and sold per lineal metre with GST included.

Installation
Fix the capping along the gable edge so the profile sits over the Trimdek ribs, with the leg running down the barge board. Fix it through the sheet into the barge board with roofing screws, and seal the top edge against the ridge capping. The profile closes the sheet end and keeps water running off the gable, and the Zincalume finish needs no painting.
Applications
- Gable ends on Trimdek sheet roofs
- Sealing the fascia to sheeting junction
- Commercial and residential metal roofs

Frequently Asked Questions
Which roof profile does this suit?
It is shaped for Trimdek sheet profiles, so it suits roofs sheeted in Trimdek or a similar ribbed profile where the 75mm rise clears the rib height.
Is the Zincalume finish painted?
No. Zincalume has an aluminium-zinc alloy coating that is left unpainted. It resists corrosion and needs no painting, which is why it is used on commercial roofs and coastal areas.
How is it cut and priced?
It is cut to your required gable run with a tolerance of +200mm / -0mm and priced per lineal metre including GST.
Can I get it in Colorbond?
Yes. The same Trimdek barge capping is available in Colorbond with a baked-on colour finish.
