Metallbaumeister/in HFP key terms

The developed length assigned to a bend under a specified geometry and neutral-axis model, not automatically the outer arc length.

The construction of a flat pattern corresponding to a formed part, accounting for actual geometry and required bend or seam allowances.

A raised sheet-metal joint arrangement whose actual geometry, movement and water performance depend on the specified roofing or cladding system.

The modeled position in a bend with no longitudinal extension or compression, used under stated assumptions to estimate developed length.

Assessment of dissimilar material contact and relevant electrolyte exposure rather than assuming every metal combination performs alike.

A designed means to accommodate the component’s relevant temperature-related dimensional change while preserving support, weathering and attachment functions.

The coordinated connection of relevant layers and interfaces intended to manage water under the actual roof design and exposure.

A designed alternative water discharge route whose capacity and safe destination require actual project verification rather than a guessed dimension.

A roof arrangement placing relevant insulation above the waterproofing layer, with system-specific loading, drainage and moisture considerations.

An action tending to lift roof or facade components, requiring an actual load path and designed attachment or ballast.

The suitability of adjacent membranes, adhesives, seams and accessories as a specified system rather than merely similar product labels.

The planned safe means to inspect, clean, repair and replace relevant components while preserving required building functions.

An enclosure arrangement separating external cladding from an inner protected assembly through a designed drained and ventilated cavity.

Photovoltaic components integrated with a building-enclosure function, requiring both electrical and relevant structural/weather performance to be coordinated.

A designed restraint location controlling a panel’s reference position, coordinated with other supports and its specified movement accommodation.

A designed support allowing specified movement while transferring relevant forces under the actual panel and fixing system.

A lower-conductivity component reducing a particular heat-flow bridge without automatically eliminating all thermal or moisture risks.

A stated rate of change of a PV quantity with cell temperature under a specified model, not an annual yield guarantee.

A defined opposition to heat flow in the supplied model, calculated from thickness and conductivity for an appropriate homogeneous layer.

A localized pathway of different heat transfer at a junction or material interruption, requiring actual geometry and assembly assessment.

The route by which actions are transmitted through members, connections and supports to the ground under the actual design conditions.

A specified part of a building assembly managing a relevant moisture route, whose continuity and connections matter beyond the visible finish.

Resistance to unintended air leakage through the relevant enclosure, distinct from deliberately provided suitable ventilation for the building’s actual needs.

The suitability of interacting materials under the intended load, moisture, movement and exposure conditions, not simply similarity of appearance.

The approved version of technical information for the actual task, preventing different workers from following incompatible dimensions, details or instructions.

A stated reference used to relate dimensions and locations consistently, rather than an arbitrary convenient edge selected independently for each part.

The specified physical size or relationship stated on a drawing, distinct from measuring a potentially rescaled printed image with a ruler.

The chosen extent of a model or task that determines which inputs, outputs, forces and responsibilities are included in the reasoning.

A characterization of the possible dispersion associated with a measurement result, distinct from the instrument’s smallest display increment.

A defined requirement used to judge appropriate evidence, which must not be replaced by an attractive appearance or an undocumented expectation.
