Material is only one layer
Alloy, coating system, pretreatment, fasteners, isolation between metals and cut-edge detailing matter alongside the visible façade material.
Problem Solvers / Global
Which façade system works best on a coastal building?
There is no single coastal façade answer. Material, coating, fasteners, cut edges, geometry, drainage and maintenance all interact with salt exposure.

Direct answer
The short version.
Start with the actual corrosion environment and maintenance plan. Aluminium systems can be strong coastal candidates with an appropriate alloy, finish and fixing strategy; mesh and perforated systems need the same attention to edges and support; weathering steel should not be assumed suitable for every marine exposure without specialist review.
Project decision
What matters before product selection.
Use these points to structure the first project conversation. Final suitability stays tied to the actual site, selected system and local project team.
Open screens collect exposure
Perforated panels, fins and mesh can have more edges and complex wash-down conditions than a simple flat panel.
Maintenance access
Specify how salt deposits will be inspected and cleaned rather than relying on the initial finish alone.

Frequently asked
Answers without oversimplifying the project.
Is powder-coated aluminium automatically coastal rated?
No. Pretreatment, coating specification, alloy, fabrication and exposure all matter.
Is weathering steel suitable beside the sea?
It needs specialist project review; continuous salt deposition can affect the intended patina behaviour.
Should maintenance be specified?
Yes. Inspection and cleaning requirements should be part of the project documentation.
