01 / Finish selection

More than a
colour reference.

A finish is a combination of colour, gloss, texture, coating system and intended environment. Each affects how the façade or component reads—and how it performs.

Swallow works with recognised powder manufacturers and surface-treatment chemistry partners. The appropriate system should be confirmed against the substrate, specification, exposure and required warranty route.

Physical samples and approved references remain essential where appearance is critical, particularly for metallic and textured effects.

Specification principle
Colour catches the eye. The complete system carries the performance.

Screen previews are representative only. Final selection should be made from an approved physical sample or manufacturer reference.

02 / Finish families

Four routes through the palette.

RAL Classic
Architectural solids

A widely specified palette for clean, repeatable solid-colour treatments across façade and fenestration work.

British Standard
Established references

Traditional specified colours for projects calling for a BS reference rather than a RAL equivalent.

Metallic
Dimensional effects

Fine metallic character that responds to light, orientation and component geometry.

Textured
Tactile / low glare

Surface texture introduces depth and can reduce the visual impact of minor handling marks.

Coastal environments
C5-suitable systems

Project-specific systems suitable for C5 environments are available where confirmed against the specification.

Colour approval
Sample-led

Use approved physical samples for critical matching; screens cannot accurately represent every finish.

03 / Selection path

Define the finish
before production.

A clear finish schedule reduces ambiguity and gives the application team the right technical starting point.

  1. 01

    Identify the reference

    RAL, BS or manufacturer-specific finish code.

  2. 02

    Confirm the character

    Gloss level, metallic effect, texture and acceptable variation.

  3. 03

    Review the environment

    Location, exposure and any coastal or warranty requirements.

  4. 04

    Approve the sample

    Physical reference agreed before production where appearance is critical.
