MHB: Pure slim steel windows and doors since 1938!

More light!
“More light” with magnificent  steel windows and doors that really do let in more light through the super slim-line steel thermo-insulated profiles (the most slim-lined profiles in the world!) that we developed in-house.  Aesthetic and superior features - in the field of thermo-insulation and wind and water - have resulted in our products being delivered over the whole world.

“More light” also stands for sustainable and socially responsible entrepreneurship. These important themes  influence the way we develop our products: low energy cost for the client; sustainable material (100% recycled steel) and very little waste are the result.  Every year we set out to achieve further improvements  in the sustainability of our production process.

Slim-lined and strong
With our slim-lined steel profile systems we have shown the market that transparency can be effectively combined with safety and strength.  On the basis of our SL30 profile system with just 30mm visual width we have even be able to develop an thermally insulated version with uniquely favourable insulation values.  The exclusive sliding door system Sky-frame  with a 20mm visual width shows that still smaller is possible.
