Aluminium is well suited to coastal work, but it is not maintenance-free.
Coating selection, damaged edges, fasteners, dissimilar-metal interfaces and regular removal of salt contamination all matter in aggressive marine environments.

Salt, humidity, UV, wind-driven rain and repeated wetting can act on coastal systems every day. Material selection, fresh-water cleaning, track care, motor testing and pre-season inspection are part of long-term protection performance.

Coating selection, damaged edges, fasteners, dissimilar-metal interfaces and regular removal of salt contamination all matter in aggressive marine environments.
Roll-down guides, accordion tracks, sliding-door tracks, locks and motors should be cleaned and operated periodically rather than left untouched until a storm warning is issued.
Inspect roll-down curtains and guides, accordion joints and tracks, Bahama/Colonial hinges and supports, impact-window drainage and hardware, fabric anchors, and louvre mechanisms according to the system and manufacturer guidance.
Identify problems before severe weather develops. After a significant storm, inspect for impact damage, loose tracks or fixings, broken glazing, electrical faults and water ingress before relying on the system again.

Opening size, positive and negative design pressures, impact requirements, tracks or frames, anchors and structural substrate all affect final performance. Apollo ties numerical wind, impact and certification claims to the applicable tested or engineered configuration rather than applying one blanket rating to an entire product family.
