Double Internal Steel Doors (French Style)

Our bespoke double steel internal doors combine timeless French door styling with the clean, contemporary appearance of ultra-slim steel framing. Designed for larger openings and statement interiors, these doors create a striking focal point while allowing natural light to flow freely between rooms. Featuring elegant steel glazing bars across both door leaves, our French-style steel doors offer the perfect balance of traditional proportions and modern architectural design. Whether connecting a living room to a dining area, separating a kitchen from a family space, or creating a sophisticated home office entrance, these doors provide a premium solution for modern interiors.

Made-to-Measure French Style Steel Doors

Every double steel door system is manufactured completely to order based on your exact opening sizes and design requirements. Our French-style steel doors can be supplied as:

• Double hinged steel doors
• Double doors with fixed side panels
• Double doors with top glazed panels
• Full-height glazed steel doors
• Heritage-inspired grid layouts
• Contemporary minimal bar designs

Each system is individually manufactured to ensure perfect proportions and a seamless fit within your opening.

Elegant French Door Design

Unlike standard double doors, French-style steel doors feature slim transom bars that divide the glazing into balanced sections, creating the distinctive appearance associated with traditional French doors. The result is a door system that feels both elegant and architectural, adding character without appearing heavy or intrusive. These carefully proportioned glazing bars create visual interest while maintaining maximum glass area and natural light transmission.

Ultra-Slim Steel Profiles

Our French-style steel doors utilise refined steel sections engineered to achieve a clean and sophisticated appearance. Profile specifications include:

• 50mm frame depth
• 20mm visible steel frame width
• 15mm glazing bars

These slim proportions maximise the glass area while retaining the strength and durability that genuine steel doors are known for.

Glass Options Available

All double steel internal doors are supplied single glazed as standard, with several upgrade options available. Choose from:

• Clear glass
• Reeded glass
• Frosted / opaque glass
• Acoustic glass upgrades
• Laminated safety glass upgrades

Clear glazing remains the most popular option for open-plan living spaces, while reeded and frosted glass provide additional privacy where required.

Colour Options

Black RAL 9005 Matt remains the most popular finish for French-style steel doors, creating the iconic steel door appearance seen in contemporary homes and architectural projects throughout the UK. Additional options include:

• White
• Bronze
• Grey tones
• Bespoke RAL colours

All finishes are professionally powder coated for exceptional durability and a flawless appearance.

Perfect for Larger Openings

Double steel internal doors are particularly well suited to wider openings where a single door may appear undersized. Common applications include:

• Living rooms
• Dining rooms
• Open-plan homes
• Kitchen transitions
• Home offices
• Commercial interiors
• Meeting rooms
• Apartment developments

Their symmetrical design creates a sense of balance and elegance while maintaining practical access between spaces.
