Our SL30-ISO®-PLUS profiles allow for triple glazing, providing even better insulation and added strength. These thermally broken profiles have all the advantages of our solid steel SL30-ISO® profiles - they are ultra-slim at 1 3⁄16”, have the same exceptional durability, and offer unrivaled design freedom - but are extra deep.
We believe in applying the proven power of solid steel profiles, combining their exceptional strength with unprecedented performance. The ingenuity of our profile systems offers architects the ultimate design flexibility with great attention to detail.
The solid steel profile strength, as measured by its bending resistance, is unrivaled by any other existing profile systems, with steel being three times stronger than aluminum.
We are the exclusive developer and manufacturer of all our steel profile systems and handcrafted steel products such as doors, windows, and entire facades. As such, we maintain a unique industry position. Other manufacturers either produce profile systems, or manufacture doors and windows using profiles produced elsewhere.
Our combined services guarantee a flexible and versatile production process without compromising on quality or deadlines. Any adjustment of one step in the production process is seamlessly integrated into the following steps because we closely supervise the entire process. We consider this dedicated focus to be essential for our unique solid steel profile systems.
Thanks to our in-house engineering and innovation, we are highly versatile when it comes to combining elements into unique facades. In addition to fully customized projects, we offer multiple unique ultra-slim SL30-ISO-PLUS configurations such as unique doors, windows, folding doors and pivot systems.
The exceptional strength of solid steel allows our revolutionary SL30-ISO-PLUS profile to be ultra-slim and highly durable. With sightlines of just 1 3⁄16” , it has the slimmest sightlines in the global market. As such, it allows in all daylight and seamlessly combines the indoors and the outdoors.
Our ultra-slim profile systems offer architects the opportunity to create exceptionally large glass surfaces with plenty of room for experimentation. We can combine steel profiles combined into unique facades without the need for additional support structures. Even very large facades can maintain their narrow sightlines of 1 3⁄16” for fixed parts of the steel frame. For elements opening outwards it is 1 15⁄16”, and 2 1⁄4” for elements opening inwards.
Our SL30-ISO-PLUS profile system has excellent thermal insulation properties and has been developed for double & triple glazing with a thickness, including glass stops, between 15⁄16” and 2 11⁄16”. Its innovative, patented thermal break system offers optimal insulation. Its thermal bridge with a thickness of only 1⁄8” minimizes the heat loss surface.
The SL30-ISO-PLUS profile has been tested and approved following the European NEN-EN 10077-1 and NEN-EN 10077-2 ISO standards as well as the American NFRC 100, 200, and 500-2014 standards.
An excellent surface treatment is crucial for a product’s life span. Powder coating is the best surface treatment for preserving steel. Out of all treatments, powder coating provides the thickest protective layer, maximizing the lifespan of our products to 100+ years with minimal required upkeep.
All our doors and windows are powder coated at our in-house certified surface treatment facility, allowing us to monitor the entire process. We are one of only a few companies worldwide with a Qualisteelcoat C5 certification, the highest possible certification for steel surface treatment. We are committed to maintaining this certification, regularly having our facilities inspected officially.
All applied coatings and colors by MHB are certified as “super durable” quality. “Super Durable” powder coatings have been specifically developed for steel windows and door frames as well as facades and meet Qualicoat class 2 GSB master as well as AAMA 2604 – 2605 specifications.
“Super Durable” powder coatings have been tested according to the ISO 2810 norm three year outdoor Florida exposure tests. Retaining color and gloss retention 3 times longer than average (see chart below).
MHB applies the following surface treatment:
Class C5 – Very high corrosive environment – ISO 12944-2:2018
Gritblasting SA 3.0, followed by thermal spraying and a 2-layer powder coating:
All our products are powder coated after full assembly, allowing our thermal zinc spraying process to offer complete protection at a level equal to the requirements for ships and oil rigs. Combined with our 1⁄4” thick solid steel profiles, corrosion has no chance, making our profiles last for 100+ years.
With the Rembrandt Collection of Exclusive Finishes you are able to choose from a unique range of high quality design surfaces. MHB’s exclusive finishes consist of a high quality design surface currently only applied for super yachts, luxury interiors and museums like the Louvre Abu Dhabi.
The Exclusive Finishes are made by applying a unique technique involving a combination of MHB’s super durable in-house powder coating with a design surface consisting of actual bronze, tin, manganese and brass. By applying different sanding, polishing and patina techniques an almost indefinite possibility of textures, structures and color effects can be achieved.
The SL30-ISO-PLUS profile system is engineered to maximize wind and water tightness following the most stringent European standards. It has invisible drainage channels and micro-engineered corner rubbers to prevent any condensation in the profiles.
All our products are weatherproofed up to a minimum of Class 4 following the European NEN-EN 12007 standard for wind resistance. They are also waterproofed up to at least Class 4A – 150 Pa following the European NEN-EN 12208 standard for water resistance. We can guarantee even higher standards of up to 1200 Pa on a project-specific basis.
MHB thermally insulated steel profile systems have received a “more than 100 years” Service Life Prediction (according to ISO 15686-2).
The SLP method for metal profile systems has a standard maximum set at 100 years, for folded steel and aluminium profile systems it is just half that term. This makes the 100+ years SLP certification for MHB unprecedented.
The 100+ years SLP certification has been achieved based on the following unique MHB steel profile system characteristics:
The Service Life Prediction has been conducted by the external agency ABT.
Our core materials and the manufacturing process of our products are in line with our environmentally friendly and sustainable business conduct.
We work with a selection of preferred glass suppliers to meet our high standards. We only accept minute size deviations of up to >1⁄32”. Our solid steel profiles also facilitate arched and rounded glass shapes. Because of our ultra-slim profiles, our glass rim sealings are extra thin. We offer three possible glass stops for our glazing: aluminum L-shaped glass stops without visible connections, aluminum triangular glass stops, and steel L-shaped glass stops with visible connections.
Divided lites give your facades a more classic look with all the fine modern qualities of our steel profiles. For true divided lites (TDL), the window is divided into smaller glass panels, all separated by steel profiles:
Simulated divided lites (SDL) are indistinguishable from true divided lites (TDL) based on their outer appearance but facilitate stronger glass panels and better insulation.
