Trueline Aluminium

Bespoke aluminium roofline and coping, manufactured by ARP to your exact dimensions.

Trueline is ARP's range of bespoke aluminium roofline and coping products, covering fascia and soffit, bullnose fascia, wall coping and cappings, and column casings. Every component is manufactured from high-strength aluminium alloy to the precise dimensions of your project — so rather than fitting a stock size, you get a system built for the exact girths, corners and returns your drawings call for.

As a metal rainwater and roofline specialist, Gutter Centre supplies the full Trueline range alongside our other aluminium roofline brands, including Alumasc Skyline. Every order is backed by real trade knowledge, not just a call centre — so if you're specifying, ordering or fitting Trueline for the first time, we can talk you through it before you buy.

The Trueline Range

Fascia & Soffit

Fascia boards in 175mm–900mm girths and soffits in 250mm–525mm girths, with a choice of standard or custom profiles.

Wall Coping & Cappings

Pressed aluminium coping and capping for parapet walls and flat roof terraces, protecting the wall head from water ingress and staining.

Bullnose Fascia

Curved bullnose fascia in 600mm–1000mm girths for a rounded roofline profile on new build and refurbishment projects.

Column Casings

Aluminium column casings in 600mm–1000mm girths, used to clad structural columns with a matching architectural finish.

Every product line above is also available as a fully bespoke item, manufactured to a custom profile where the standard range doesn't cover your project.

Trueline Aluminium Fascia and Soffit

Trueline fascia and soffit is manufactured to bespoke dimensions rather than supplied as fixed stock lengths, so every board, corner and return lines up exactly as specified. It suits new build roof perimeters, refurbishment and re-roofing projects, and can be manufactured to integrate with a concealed guttering system or fitted behind existing guttering on a straightforward replacement.

Trueline Aluminium Wall Coping & Cappings

Trueline wall coping and cappings sit on top of parapet walls and flat roof terraces, forming a barrier against rain and preventing unsightly staining to the wall face below. As with the rest of the range, coping is manufactured to your exact dimensions from high-strength aluminium sheet — a lighter, lower-maintenance alternative to traditional stone coping, with a faster, simpler installation. Copings project outward over the parapet edge; cappings offer a curved finish as an alternative for flat roof upstands.

Colours & Finishes

Trueline components are finished in polyester powder coating, with access to over 200 standard colours plus BS and RAL colours to special order — including RAL 7032 — so fascia, soffit and coping can be colour-matched across the same building. Aluminium sheet gauges of 2mm–3mm are used depending on the product and application, giving a durable, low-maintenance finish that won't rot, warp or discolour the way timber and uPVC roofline products can.

Manufacture & Bespoke Design

Every Trueline order is manufactured to bespoke dimensions from high-strength aluminium sheet, with pre-drilled fixing holes to simplify installation on site. Because each order is made to spec, ARP can work from your construction drawings, provide design consultation, and arrange a site survey to confirm dimensions before manufacture — reducing the risk of costly on-site alterations. Custom profiles are available across the range where a standard fascia, soffit, coping or bullnose profile doesn't fit the project.

Installation & Technical Support

Trueline fascia can be fitted behind existing guttering or specified as part of a concealed gutter system, while coping and cappings are designed to fit directly over parapet walls and upstands. We recommend confirming fixing details and profile compatibility with our technical team at the quote stage, particularly on projects combining several Trueline product lines — for example fascia and coping on the same elevation.

How is Trueline different from Alumasc Skyline?

Both are aluminium roofline brands we supply.
