TRANSPORT-HUB METAL ROOF REFERENCE
New Shenzhen Station Metal Roof: Continuity Across Long Roof Zones
A procurement and installation review for membrane control layers, junction details, temporary weather protection and phased roll-material delivery on a large railway-station roof.
CONTINUITY PLAN
Break the long roof into traceable control-layer zones
Platform and track-side zones
Wind-driven rain, open sides and pressure changes can increase local exposure. Confirm securement, lap direction, edge restraint and temporary termination details for these roof areas.
Concourse and entrance halls
Occupancy and conditioned interior space can create different vapor and air-control requirements from open platform roofs. Define the layer position from the full thermal and moisture design.
Longitudinal roof runs
Long runs magnify dimensional tolerances and accumulated alignment error. Plan roll direction, joint staggering, movement breaks and restart locations before selecting roll length.

FAQ
Transport-hub metal roof questions
Can the same breathable membrane be used over enclosed halls and open platforms?
Possibly, but only after the layer function and exposure in both assemblies are checked. Enclosed conditioned spaces can have different air and vapor-control requirements, while open platform zones may face greater wind and temporary weather exposure. Product equivalence should be demonstrated against the requirements of each zone.
How should roll direction be selected on a long station roof?
Coordinate roll direction with roof slope, drainage, structural geometry, wind exposure, safe handling and the approved lap sequence. Longitudinal installation may reduce some transverse joints, but can complicate movement zones or handling. The drawing should show restart and termination locations before roll length is fixed.
