Pure Solid Steel

The world’s slimmest... The SL30-ISO® profile is one of MHB´s most valued innovations. It makes use of the specific qualities of steel to create a very slim, strong and durable profile that is perfectly wind and watertight and has insulation values few others can match. With a sight line of 30 mm it is the slimmest steel profile system on the market today.

...in every detail The MHB sharp-edged steel profiles allows for the creation of ultra-slim facades, windows and doors. The combination of the inherent strength of steel with smart design gives architects the freedom to play with large glazing areas. The very slim sight line of the SL30-ISO® profile integrates perfectly into the outlines of a building. Being almost invisible, it allows huge amounts of light to flood in.

Strength comparison Standard MHB profiles have a very high bending resistance value in comparison with other common profile systems. Folded sheet metal Ix = 22,1 cm4 The strength of glazing systems is determined by the ability to resist bending. This stiffness is expressed in the Ix value. The higher the Ix value, the stronger the profile system is in the direction of X. Expressed in Ix of steel.

Strength The MHB profile system is the slimmest and strongest profile system in the world. The patented crimping technology allows the thermally broken profile to maintain the strength of solid steel. Focus on steel MHB comprises of 200 people focusing exclusively on the development and production of steel windows, doors and facades. Aesthetics The structural strength and design of MHB’s profile systems allows architects to create transparent steel facades with exceptional design freedom. Even for the largest units, in every configuration, the narrow sightlines of 30 mm (fixed frame) and 50...

MHB A tradition of craftsmanship & innovation MHB is a proud family business founded in 1667. The Mathijssen family worked as blacksmiths before starting the production of steel windows in 1938, providing MHB with a solid base and identity. Today, MHB employs over 200 professionals focused on the development and production of steel doors, windows and facades. MHB has reinvented the door- and window industry with its thermally broken steel profile series and is leading the revolutionary reintroduction of steel as integral part of the most beautiful buildings. We combine a constant focus on...

MHB’s fixed glazing window profiles make it possible to realize transparent steel facades with large (True Divided Lite) glass surfaces with minimal sightlines of 20 mm (building to glass) and 30 mm (glass to glass). The exceptional structural aspects of MHB steel profiles allow architects to design bigger and higher frames for large glass panes, bringing in more light and creating breathtaking views.

Wind and water tightness Thermal insulation The SL30-ISO® steel window system is able to conceal a fully integrated water drainage system within the profiles thanks to the system’s superior sealing components. This results in a high level of wind and water tightness without any visible holes or rain caps. All MHB products comply with class 7A - 150Pa of EN12208 for water resistance and with class 4 of EN12007 for wind resistance. When required, MHB can guarantee a higher performance of 600Pa. MHB products achieve excellent insulation values thanks to the high performance thermal separation...

Surface treatment Surface treatment is crucial for a product’s life span. All MHB windows and doors are powder coated in-house. MHB only uses the “Super Durable Quality” of Axalta Coating Systems to ensure the best service treatment available. Surface treatment Depending on the location of the project, MHB applies different surface treatments. MHB distinguishes between 2 classifications: 1: Class C3 - Medium corrosive environment* - ISO 12944-2:2018 Powder coating You can choose between different finishes: Powder coating is the best available method of preserving steel. All MHB windows and...
