MHB Steel Sliding Systems

Exterior steel sliding systems for projects where sightlines, movement, track configuration and the architectural language of steel need to be considered together. Royal Design Marbella represents MHB across the Costa del Sol and helps project teams review the opening, available drawings and the appropriate MHB route.

This is not a generic sliding-door category. It is a specific MHB steel system.

MHB steel sliding systems are considered around the material, the proportions of the opening, the track arrangement and the way the moving leaves relate to the wider steel architecture.

The useful starting point is therefore the actual opening: its width and height, the desired movement, whether the system works with a pocket or sidelight, and the requirements already defined by the project team.

The configuration is defined around the opening and the project requirement.

The documented MHB sliding system combines thermally broken steel profiles with different movement and track configurations. The relevant route depends on the dimensions, glazing, opening arrangement and performance requirements of the project.

66 mm profiles Leaf width up to 2000 mm and height up to 3000 mm
86 mm profiles Leaf height up to 4300 mm
Leaf weight Maximum documented leaf weight of 400 kg
Glazing Up to 38 mm with 66 mm profiles and up to 58 mm with 86 mm profiles
Operation Documented operating ease of approximately 50 N

Published maximum values and classifications depend on the documented test or configuration. The applicable system route should be confirmed for the individual project.

Thermal transmittance Up to Uw 1.2 W/m²K 4000 × 3600 mm · Ug = 1
Water tightness Up to 400 Pa Class 7A · NEN-EN 12208
Air permeability Up to Class 4 Documented MHB performance
Windload resistance Up to Class C5 NEN-EN 12210
System views and configurations

Understand the system before the opening is fixed.

These technical renders help explain the relationship between the sliding leaves, the frame and the available movement routes. The appropriate arrangement should be reviewed against the actual plans and opening.

Possible MHB steel sliding system configurations

Standard routes include pocket and sidelight configurations. The project defines the final arrangement.

The documented system overview includes single or bi-parting movement, pocket or sidelight routes and configurations with up to three leaves per side. MHB also documents project-specific routes beyond the standard configuration overview.

See the system in motion

A sliding system is better understood when the movement can be seen.

The video shows the MHB sliding concept in operation and helps make the relationship between the moving leaves, sightlines and opening configuration easier to understand.

03 · Movement

The architectural decision involves more than opening and closing. It is also about how the steel leaves align, move and disappear within the composition.

The material decision

Movement is one part of the system. Steel is the architectural language.

The MHB route becomes relevant when the project specifically calls for steel-framed sliding architecture rather than a generic sliding opening.

The solid steel profile system, sightlines, glazing, track arrangement and relationship with other MHB elements can then be reviewed as one project composition.

From opening to system conversation

Start with the opening. Then review the appropriate MHB sliding route.

Royal Design Marbella represents MHB across the Costa del Sol, helping architects, designers and project teams review available project information and coordinate relevant drawings, quotations and technical conversations. The exact execution route depends on the system, project and MHB process.

01

Share the opening

Provide the available plans, elevations, dimensions and the intended relationship between the interior and exterior spaces.

02

Review the sliding route

The movement, track configuration, glazing and available project requirements can be reviewed in the context of the MHB system.

03

Coordinate the next information

Drawings, quotations and relevant technical conversations can then be coordinated according to the project and applicable MHB process.
