TRADITIONAL MOULDED OGEE GUTTERS

Moulded Ogee Aluminium Gutters - 125x100mm Traditional Cast Style (5x4")

Our Traditional Moulded Ogee Aluminium Gutters (also known as cast moulded ogee 5x4 or 125x100mm metal ogee gutters) are the ideal replacement for ageing cast iron systems on heritage, listed, or period properties. Manufactured from premium marine-grade aluminium (LM6 for cast parts, 6063 T6 for extrusions), these gutters replicate the classic 19th-century ogee profile while offering modern advantages: lightweight design for easy handling, zero rust or cracking, and a functional life expectancy of over 50 years—even in coastal or harsh UK environments. Compliant with BS 8530 and BS 9101:2017 standards, they provide superior corrosion resistance and are fully recyclable, making them a sustainable choice.

Compatible with our 63mm, 76mm Traditional round, or 72x72mm Traditional square downpipes for seamless integration.

Key Benefits of Moulded Ogee Aluminium Gutters

• Durability and Longevity: Unlike cast iron, our aluminium gutters won't rust, crack, or require frequent repainting. With architectural-grade polyester powder coating (PPC), they resist UV fading and corrosion for 40-50 years in rural/suburban areas. Lighter than steel or iron but stronger than PVC—perfect for UK weather.

• Aesthetic Appeal:Inspired by Victorian cast iron designs, these 125x100mm (5x4") gutters blend seamlessly with traditional architecture. Available in our various standard RAL colours or custom RAL/BS colour finishes.

• Easy Installation: Options for rafter arms or rise-and-fall spikes. Joints use silicone sealant (SU1) and nuts/bolts (SU5) for a watertight seal. Brackets spaced at 915mm max for stability in high winds or snow.

Frequently Asked Questions About Moulded Ogee Aluminium Gutters

What are moulded ogee aluminium gutters?

Moulded ogee gutters feature a curved, S-shaped profile inspired by 19th-century cast iron designs. Our 125x100mm (5x4") version is cast from LM6 aluminium for a lightweight, durable alternative suitable for heritage or modern UK properties.

What's the difference between extruded and moulded ogee gutters?

Extruded gutters are formed by pushing aluminium through a die for consistent shapes, while moulded (or cast) versions use moulds for intricate details. Ours are cast from LM6 aluminium for authentic details and durability, mimicking traditional moulded aesthetics.

How long do moulded ogee aluminium gutters last?

With proper installation, expect 50+ years. They're rust-proof and require minimal maintenance, outperforming PVC or steel in harsh weather.

Are these gutters easy to install?

Yes—Use brackets at 915mm intervals; joints seal with silicone and bolts. No specialist tools needed beyond a mitre saw.

What colours are available for 125x100mm ogee gutters?

Offered in our standard range of colours, and can also be supplied in any RAL or BS colour code. 

What is the flow capacity of these gutters?

2.2 L/s (end outlet) to 3.8 L/s (central outlet), handling roofs up to 180m² per downpipe. Ideal for UK climates.

Do they comply with UK building standards?

Yes, BS 8530 for rainwater goods and BS 9101:2017 for design/manufacture. Fully recyclable and sustainable.

How do I maintain moulded ogee gutters?

Clean annually with a soft brush to remove debris. No painting needed initially; repaint after decades if the finish fades.

Are they compatible with cast iron systems?

Yes, dimensions match traditional cast iron for easy replacement. Pair with our traditional downpipes for a seamless fit.

Why choose aluminium over cast iron for ogee gutters?

Aluminium is lighter, easier to install, and corrosion-resistant without the weight or rust issues of iron. It's also more affordable long-term with lower maintenance.
