Arched steel windows.

Arch steel doors introduce a striking architectural presence in both residential and commercial spaces. Custom-crafted to the exact dimensions of each project, our single and double arch doors balance refined aesthetics with everyday functionality.

Where a full arch frame isn’t feasible, curved designs can be seamlessly integrated into standard openings, achieving a distinctive look without compromise in performance.

Available in a variety of finishes and glass options, each arch steel door is tailored to reflect the unique character of its project.

What are the benefits of choosing steel windows and doors?2025-09-05T02:30:19+10:00

Steel windows and doors manufactured with the Metro M40 System offer unmatched strength while providing slim sight-lines and a modern aesthetic.

They are more durable than alternatives such as wood or uPVC, and unlike aluminium or some other steel profiles, the M40 profile supports large panes of glass without requiring additional mullions, transoms, or bulky reinforced frames.

The Metro M40 System is a complete window and door solution designed specifically for the Australian market. Suitable for both internal and external applications, it combines the classic W20 and W40 steel profiles with the innovation of the Italian Secco systems to deliver a durable, contemporary, and cutting-edge steel window and door solution.

Are steel windows and doors energy efficient?2025-10-07T22:49:38+11:00

Yes, steel windows and doors can be highly energy efficient.

The Metro M40 System is designed specifically for Australian conditions and can accommodate single and double glazing, with or without low-e coatings. All our windows and doors feature premium weather seals to enhance performance and comfort.

For projects that demand advanced insulation, we recommend the Secco OS2 system. The OS2 75 profile incorporates state-of-the-art thermal break technology with high-density polyurethane insulation, while still allowing for double, or triple glazing.

Are steel windows and doors rust or corrode resistant?2025-10-07T22:50:32+11:00

Yes — the Metro M40 System and range of profiles are rust and corrode resistant. Engineered for durability and long-lasting performance, the M40 System is cold-rolled from a galvanized material, eliminating the need for a hot-dipped galvanization process which is often seen with the traditional W20 and W40 profiles made from a mild steel.

Are steel windows and doors heavy?2025-10-07T22:51:13+11:00

Steel windows and doors made from mild steel are often heavy and require additional structural support. In contrast, products made from our M40 profile are up to 35% lighter, while also being straighter and stronger than traditional steel profiles.

This means you get the timeless strength of steel in a design that’s elegant, functional, and built to last, without the unnecessary weight.

How durable are steel windows and doors compared to other materials?2025-09-05T02:35:53+10:00

Steel is approximately three times stronger than aluminium and far more durable than wood or timber, which can rot or require ongoing maintenance.

The Metro M40 profile is 35% lighter than traditional steel profiles, yet stronger, allowing for larger spans of glass without compromising on structual integrity. Made from galvanized steel, the M40 System avoids common issues like warping or mill scale that can occur with heat-treated mild steel used in traditional steel windows and doors. Its smooth, flat surface requires no bog filling or sandblasting, providing a superior finish straight from the factory.

Additionally, steel is naturally non-combustible and fire-resistant, ensuring that windows and doors made with the M40 profile offer long-lasting strength, safety, and performance.

Can steel windows and doors be customized to fit unique sizes and designs?2025-10-07T22:52:33+11:00

Absolutely. Every steel window and door we manufacture is custom-made to suit your project, tailored in both dimensions and design. Whether you’re aiming for a sleek modern look or a classic style, our Metro M40 System brings your vision to life.
