WILLSTRONG StrongLock Mechanical Fixing System for Facades

Hang it. Lock it. Done.

Stronglock is a hook-on facade installation system: panels hang directly onto pre-set aluminium extrusions and lock in place with U-shape hooks. No wet trades, no exposed fixings — just a fast, repeatable mount built for high-rise scale.

Hidden hooks carry the full load of the panel while staying out of sight — giving high-rise facades a fast, secure mount with a clean face.

Benefits:

Reads like a traditional rainscreen no visible change to the finished look.
Cuts installation time and labour cost versus wet-fixed systems.
Base extrusions are shimmed level and fixed to the wall first.
Panels are measured directly off the installed extrusion.
Panels hook straight onto the rail and lock with U-shape hooks.
