Two shutters can look identical from the footpath and be entirely different objects. One is a window covering that happens to be made of aluminium. The other is engineered so that a person trying to get through it fails. The difference is in the parts nobody photographs. Here is the anatomy of security plantation shutters : what changes in the frame, the blades, the fixings and the locking when a shutter is built to resist rather than just to look good. The material, and why aluminium is the starting point Timber and polymer shutters are not security products. They can be locked, and a lock on a blade that snaps is a formality. Security starts with a material that does not break under leverage or impact. Extruded aluminium is the baseline. Blades and frames extruded as solid or reinforced sections resist bending and breaking in a way flat-pressed or hollow sections do not.
