Steel-look Heritage
Bi-folding Doors

Blending timeless character with modern performance, our steel-look heritage bi-folds are a striking addition to any home. Designed with a specially developed sash that mirrors the appearance of classic steel doors, they open up living spaces while echoing the charm of a bygone era.

Whether you're renovating a period property, working within a conservation area, or adding a touch of heritage to a new extension, these aluminium bi-folds pair beautifully with our matching external windows and heritage doors — creating a cohesive, characterful look across your home.

Smooth to operate, low-maintenance, and thermally broken for year-round efficiency, they meet today’s requirements for safety, security, and accessibility, while staying true to traditional aesthetics.

Innovative design, traditional aesthetic

Decorio heritage bi-folding doors offer a seamless replacement for old steel doors, maintaining the classic look essential for historic and period properties.

Their versatility, however, extends far beyond traditional settings—these doors are equally at home in modern residential and commercial projects, adding character and style with a steel-look finish and contemporary performance.

Two Sets of Heritage Bifold Sash in Bronze

No matter the size of your project, we’ve got the perfect solution.

‍
Our heritage bi-folding doors begin with a two-panel setup and expand right up to nine-panel configurations — perfect for wide openings, garden rooms, or bold architectural statements.

But they’re not just for big spaces. The same system can be styled as a single or French door, allowing you to carry the same elegant steel-look aesthetic throughout your home. Whether it’s for a compact rear entrance or a grand patio reveal, Decorio bi-folds offer flexibility without compromising on heritage charm.
