Corner Barge Flashings in Galvanised Finish - 3m 150 x 150mm
Corner barge flashings provide a simple way to tidy and protect the edge of your roofing or metal cladding installation by sealing the end of your sheet run. This helps keep your building weather resistant while giving it a clean, professional finish. Our galvanised steel corner barges are designed to complement your chosen galvanised sheets, making it easy to achieve the completed look you want on your box profile or corrugated project.
About Our 150mm x 150mm Corner Barge Flashings In Plain Galvanised Finish
Our 3m galvanised corner barge flashings offer a tidy and practical way to complete the edge of your metal roofing or cladding. This smaller 150mm size is ideal for customers who want a lighter, more subtle trim that still seals and protects exposed sheet ends while improving the overall finish of their project.
Each flashing is folded to a 90° internal angle and can flex by around 10 to 15 degrees, helping you achieve a close fit even where the roofline varies. A reinforced welt adds strength and supports a secure edge that remains durable in everyday weather.
Despite having a 90° internal angle, the flashings can be flexed within 10-15° to adapt to project needs and for a simple installation. The corner barges also feature a reinforced welt for a more secure edge and increased strength in general.
Benefits of 150mm x 150mm Corner Barge Flashings
- Creates a slim and neat edge to smaller sheeting projects
- Fits a range of roofing profiles and angles
- Reinforced welt for a strong trim
- Galvanised surface to pair seamlessly with galvanised sheets
If your project requires a different size or a specific profile, you can submit your measurements through our custom flashings page and we will create tailored options where possible.

Fixing Guidance
Install these corner barge flashings using our 22mm stitcher screws for a secure finish. When joining several lengths, ensure that each piece overlaps enough to maintain a continuous weather‑tight seal.
If you need additional hand protection, our Cut Level 5 safety gloves are available and are well suited to handling flashings and roof sheets.
For full installation advice on fixing flashings to roofing and cladding sheets, please refer to the appropriate installation guide.

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.
When you arrive, please bring your order confirmation and follow the signage to the collection area where a member of our team will assist you.
