Product Details and Specification

The product page states that this is a custom-fabricated item made to the selected size and finish, and that it is non-returnable unless faulty.

Where This Product Is Commonly Used

This aluminium half round gutter 135° internal corner is commonly used on homes, extensions, commercial buildings, listed-style properties, offices and refurbishment projects where the roofline includes an internal angled return or recess.

It is especially useful as part of a complete rainwater goods installation, alongside aluminium half round gutters, outlets, joints, brackets, downpipes and related accessories. The 135° internal angle is useful where a standard 90° corner is not suitable for the building layout.

Where the wider exterior finish matters, the selected RAL colour can also be coordinated with fascia and soffits, aluminium copings, cladding, trims and architectural metalwork.

Why Aluminium Is a Good Choice

Aluminium is a practical material for gutter corners and rainwater fittings because it is lightweight, strong, long-lasting and highly corrosion resistant. The Council for Aluminium in Building explains that aluminium naturally forms a protective oxide coating, is highly corrosion resistant, and can accept surface finishes such as powder coating.

For UK roofline projects, these qualities make aluminium suitable for exposed gutter corners that face regular rain, moisture, wind and changing temperatures. Aluminium does not rust like some ferrous metals, and it can provide a clean finish with low ongoing maintenance when installed correctly.

Finish and Colour Options

This product includes a RAL colour selection option, allowing the aluminium gutter corner to match or coordinate with the wider rainwater system. This is useful when matching the corner with half round gutters, downpipes, fascia, soffits, copings, cladding and other roofline details.

For general colour reference, buyers can check official RAL colour information. The official RAL site lists colour systems including RAL Classic, RAL Effect, RAL Individual and RAL Digital.

Screen colours can vary, so the final RAL colour should always be checked carefully before ordering.

Installation and Ordering Notes

Before ordering this aluminium half round gutter 135° internal corner, check the roofline angle, gutter profile, gutter run length, outlet position and the number of joints and brackets required. The correct corner fitting will depend on the building return, gutter layout and wider rainwater design.

You should also confirm any required accessories before ordering, including half round gutter lengths, gutter joints, outlets, brackets, downpipes, bends, shoes, colour coded fasteners and sealant. Where the gutter system forms part of a wider drainage design, UK Approved Document H: drainage and waste disposal may be useful for general project guidance.

This product is custom fabricated to the selected finish. Please check the RAL colour, compatibility and required accessories carefully before ordering, as the product page states that custom-fabricated items are non-returnable unless faulty.
