Technical Information

Size Options

Aluminium Robust Secret Fix Soffits are supplied in standard 3,000mm lengths, ensuring consistency and ease of handling on-site. For projects with non-standard dimensions or unique design requirements, bespoke lengths and profiles can be manufactured to order.

We can accommodate project-specific detailing, including optional ventilation slots, to support building regulations or design intent. All soffit profiles are brake-pressed to precise tolerances for a clean, professional finish.

Accessories

To ensure seamless integration and continuity across the eaves, a full range of pre-fabricated accessories is available, including:

  • Internal and external corners

  • Apex angles for pitched roof transitions

  • Step transitions between differing fascia heights or levels

These fully fabricated accessories are produced in-house and powder coated to match the soffit finish, saving time on site and maintaining a high-quality appearance throughout the installation.

Brackets

Where structural support is required, large soffit voids, full soffit support hanging systems can be supplied.

These brackets are engineered to provide robust support while remaining discreet, preserving the clean lines of the Robust Secret Fix Soffit system. They are compatible with a variety of fascia arrangements.
