Ottostumm Mogs Steel Crittal Doors
Cape Glass Ltd supplies and installs Ottostumm | Mogs steel doors and windows.
This is a beautiful, bespoke system, known for combining the authentic, minimalist aesthetic of early 20th-century industrial design with modern performance engineering.
Cape Glass' Ottostumm Mogs steel Crittall-style doors offer:
-
Ultra-Slim Profiles & Maximum Light: Due to the superior structural strength of steel (3x stiffer than aluminum), Mogs profiles are extremely slender—some as narrow as 18mm—allowing for maximum glass area and natural light.
-
Authentic Hot-Rolled Steel: They are among the few manufacturers using the original hot-rolling production technique, providing a refined, authentic industrial look with solid, thick profiles (3–5 mm).
-
You have the option of upgrading to a system option with superior thermal performance (Thermal Break). Despite their slender appearance, systems like W50 TB and W75 TB feature advanced high-density polyurethane or polyamide thermal breaks, providing high energy efficiency and insulation that meets modern, strict building regulations.
-
Unmatched Durability: Constructed from hot-dip galvanized steel, these doors are highly resistant to rust and corrosion, designed to last decades, or even centuries, making them a long-term investment.
-
High Security & Safety: The robust, welded construction provides exceptional rigidity and anti-intrusion security, which can be enhanced with multi-point locking systems and security glazing.
-
Design Versatility & Customization: Available in a wide range of materials (galvanized steel, stainless steel, Cor-Ten, or bronze) and finishes (custom RAL colors). They can be configured as hinged, sliding, folding, or pivot doors, suitable for both internal partitions and external facades.
-
Superior Acoustics: Due to the thickness of the steel and capacity for heavy-duty insulating glazing, they offer high sound reduction.
