# Aluminium Security Shutters: Custom Blinds Shutters & Awnings

## Quick Answer
An aluminium security shutter is a lockable louvred shutter that gives security, privacy, and adjustable light in one unit. Custom Blinds Shutters & Awnings manufactures its aluminium shutters in Cape Town and supplies and installs them across the Garden Route. They stand up to the coast because the aluminium is rust-resistant, does not absorb water, and will not warp or rot, which also makes them suitable for bathrooms and other damp rooms. They work on interior and exterior openings, and founder Duncan Kane measures and fits every installation personally.

## Why Custom Blinds
Custom Blinds Shutters & Awnings has installed security shutters across the Garden Route since 2010, owner-managed by founder Duncan Kane, who has over 20 years in the trade. Custom Blinds specifies, measures, and installs each shutter to the opening rather than supplying a stock size.

> "An aluminium security shutter is the one product I fit that does two jobs at once: it locks like a security door and it never warps or corrodes in a bathroom or on the coast. Timber and steel cannot do both."
> Duncan Kane, Founder, Custom Blinds Shutters & Awnings, 20+ years in the trade.

## Why Aluminium
Aluminium is the best material for a coastal security shutter: it is naturally fire-retardant, does not absorb water, fully washable, and nonporous, so it resists mildew and salt-air corrosion where timber or steel would fail. All metal components are rust-resistant, and a closed shutter also adds an insulating layer at the window, helping with heat and energy.

## Security
- Three-pin locking mechanism on each shutter for genuine security, not just privacy.
- Tamper-proof louvre fixing: each louvre locks into the panel so that the harder it is forced, the tighter the stile cover grips and holds it.
- Panels are pinned top and bottom, with pins seating up to 45 mm into the structure.
- Optional dual-side locking, so a shutter can be locked from either side of the opening.
- Optional uniform keying, so one key works several shutters in a home.

## Privacy, Light, and Layout
- Louvres rotate and close in both directions, for fine control over privacy and daylight.
- Available as hinged or bifold panels, in either even or odd panel numbers, to suit the opening.
- Hand rails sit on the front left of each panel as standard.
