About Our 90° Internal Corner Barge Flashing and Z‑Bar Kit for Standing Seam
Internal corners are a key finishing point on standing seam projects, and this convenient kit provides a neat, professional solution. Each set includes a 120mm x 120mm 90° internal corner barge flashing and two matching Z‑bars, designed to create a consistent, protected corner detail across roofing or cladding installations.
Manufactured from SSAB Nordic quality steel with a GreenCoat® Pural BT finish, the components offer strong scratch resistance, reliable colour consistency and long‑term durability. The eco‑conscious Pural BT coating, produced using Swedish rapeseed oil, aligns visually with Cladco standing seam sheets for a cohesive, modern look.
Supplied in 3m lengths, the kit is designed specifically for Cladco standing seam systems, helping you achieve a streamlined, fixing‑free aesthetic at the building’s internal corners.

Fixing Guidance
Set your Z‑bars to form the internal corner line, then clamp the internal corner barge flashing over the Z‑bars using seaming pliers to maintain the concealed‑fix standing seam appearance. If you need seaming pliers, these are just one of the specialist tools included in our standing seam roofing tool kit, which provides everything you will need for an efficient, hassle‑free installation.
If your project is situated in exposed, coastal or high‑wind locations, installers may discreetly reinforce with colour‑matched 6.3x20mm Ruspert®‑coated or stainless steel screws. This does result in a non‑concealed fixing, yet the matching head tone prevents it from drawing attention.
For the full tool list, positioning advice and step‑by‑step guidance, please refer to our standing seam installation guide on the Help & Advice page.

Customer Collection Notice
Please ensure you have pre-booked your collection slot before travelling to site.
When arriving to collect your order, please report to a member of our Warehouse Team who will register your arrival and locate your goods. Once ready, your items will be picked and brought to your vehicle loading area.
During busy periods, there may be a short wait while our yard team assist other customers or complete other loading tasks. We always do our best to work within your booked collection time.
We respectfully draw your attention to the following important points:
- Loading is ultimately the customer’s responsibility. While our team can assist with mechanical loading using forklifts, we cannot handball items into enclosed vehicles. Customers must ensure their vehicle is suitable and that goods are safely loaded and adequately secured before leaving the premises.
- Sharp sheeting, metal goods, and long/heavy items may pose additional handling risks. Please come prepared with high-quality protective gloves, and any appropriate protection materials to avoid damage to your vehicle or restraints (e.g. ropes or straps). The edges of roofing sheets and metal products can be extremely sharp, and care should be taken when handling.
- We strongly recommend that customers bring their own straps, ropes, or other securing materials, as we are unable to provide these at the point of collection.
- If you are unsure of your vehicle’s load capacity, we can advise the approximate weight of your order in advance. It is your responsibility to ensure your vehicle is suitable for transporting the goods safely and legally.
- Cladco will not be held liable for any damage to your vehicle or goods once they have been loaded and leave our premises. Loading assistance is provided entirely at the customer’s own risk.
Click & Collect – Pre-Booking Required
You are welcome to collect your order from either our Okehampton (Devon) or Andover (Hampshire) site. All collections must be pre-booked in advance so your items can be picked, packed and ready for you.
Please do not travel to site without a confirmed collection time, as we cannot guarantee your order will be available.
Once your items are ready, you will receive an email with a link to book your collection slot. Please note, same-day collections are not available and bookings must be made at least two hours in advance.
