MHB fire-rated steel door system within an architectural interior
MHB · Fire-rated steel door systems

MHB fire-rated steel doors, where protection requirements meet architectural clarity.

Steel-framed glazed door systems for projects with defined fire protection requirements. Royal Design Marbella represents MHB across the Costa del Sol, helping project teams review the brief, available drawings and the appropriate MHB route.

Safety requirements should not force the architecture into a different visual language.

MHB fire-rated steel doors are considered as part of the architectural composition. The frame, glazing, opening and required performance need to be reviewed together.

The starting point is therefore the actual project brief rather than a generic fire-door specification.

Defined performance, reviewed as part of the complete configuration.

The current MHB information for this route identifies the SL30® system and testing for fire-resistant doors and glazed screens.

The relevant configuration depends on the project requirements, so the opening, drawings and required performance should be reviewed together.

Doors Tested and certified according to EN 1634-1
Screens Tested according to EN 1364-1
Listed classes EW30 · EI₂30 · EW60 · EW90 · EW120

The applicable classification and configuration must be checked against the requirements of the individual project.

Architectural integration

Performance matters. So does the way the opening belongs to the space.

Proportion, glazing, steel lines and performance need to be considered as one project question. The objective is to resolve the requirement without losing the visual clarity of the architecture.

03 · One composition

Steel, glass and the required performance should continue to read as one architectural composition.

04 · Smoke resistance
A separate performance requirement

Smoke resistance should be identified clearly in the project brief.

MHB identifies smoke-rated doors as a specific performance route within its steel interior door systems.

The exact solution should be discussed from the actual project requirements rather than assumed from the appearance of the door.

From brief to technical conversation

Start with the project. Then identify the appropriate MHB route.

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

01

Share the project context

Provide available drawings, opening information and defined performance requirements.

02

Review the MHB route

The available information is reviewed to identify the relevant system conversation.

03

Coordinate the next information

Drawings, quotations and technical conversations can then be coordinated for the project.
