Internal Steel French Doors

Our bespoke internal steel French doors combine classic French door proportions with contemporary steel framing to create elegant transitions between rooms while maximising natural light and visual openness. Designed for homeowners, architects, and interior designers seeking a timeless steel door solution, our internal steel French doors are manufactured completely to measure and can be tailored to suit both modern and traditional interiors. Whether you are dividing a kitchen and dining room, connecting living spaces, creating a home office entrance, or designing a full steel partition system, our French-style steel doors deliver a refined architectural finish that never goes out of style.

Made-to-Measure Internal Steel French Doors

Every steel French door system is manufactured specifically for your project. Unlike standard off-the-shelf products, our internal steel French doors are designed around your exact opening sizes and preferred layout, ensuring balanced proportions and a premium finish. We can manufacture:

• Single internal steel French doors
• Double internal steel French doors
• French doors with fixed side panels
• French doors with top lights
• French doors with side panels and top lights
• Full steel partition systems incorporating French doors

This flexibility allows us to create everything from simple room dividers to impressive full-height glazed steel screens.

Choice of French Door Designs

One of the defining features of our internal steel French doors is the ability to customise the glazing bar layout. Customers can choose from a variety of transom bar designs, ranging from minimal contemporary layouts to traditional heritage-inspired configurations. Popular options include:

• Horizontal transom bar designs
• Traditional French door grids
• Heritage industrial-style layouts
• Contemporary minimal bar designs
• Custom glazing patterns

This allows each door system to be tailored to the style of the property and the overall interior design scheme.

Ultra-Slim Steel Profiles

Our internal steel French doors are manufactured using slim steel sections designed to maximise the glazed area while maintaining excellent structural strength. Profile specifications include:

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

These slim sightlines create the elegant steel-framed appearance that has made internal steel doors one of the most desirable interior features in modern homes. Steel-framed French doors are particularly valued for their ability to divide spaces without reducing the flow of natural light.

Glass Options Available

All internal steel French doors are supplied single glazed as standard, with a range of upgrade options available. Available glazing options include:

• Clear glass
• Reeded glass
• Frosted glass
• Acoustic glass
• Laminated safety glass

Clear glass remains the most popular choice for open-plan living spaces, while reeded and frosted glass offer increased privacy without sacrificing light.

Colour Options

Black RAL 9005 Matt remains the most popular finish for internal steel French doors, delivering the timeless steel-framed appearance seen in many architectural interiors. Additional options include:

• White
• Bronze
• Grey tones
• Bespoke RAL colours

All finishes are professionally powder coated for durability and long-term performance.

Perfect for Homes and Commercial Interiors

Internal steel French doors are particularly suited to:

• Living rooms
• Dining rooms
• Kitchens
• Home offices
• Hallways
• Apartments
• Commercial offices
• Meeting rooms

Their symmetrical design creates a strong focal point while maintaining visual connectivity between spaces.
