# Aluminium Shutters — Custom Blinds Shutters & Awnings

## Quick Answer
Custom Blinds designs, supplies and installs aluminium shutters across the Garden Route. Aluminium is the specified shutter material for coastal, exterior, and security positions — powder-coated, corrosion-resistant, and built for the salt air, UV, and wind of Knysna, Plettenberg Bay, and the wider Eden district. Every aluminium shutter is measured and engineered on-site by Duncan Kane. There is no online price — these are made-to-site and require a consultation.

## Product: Aluminium Shutters

Aluminium shutters use powder-coated extruded aluminium louvres in a fixed or adjustable frame. They are the durable, low-maintenance alternative to timber and the correct specification anywhere moisture, salt, or direct weather rules out wood.

**Key Specifications**
- Louvre material: powder-coated extruded aluminium
- Louvre sizes: 64mm, 89mm and larger architectural blades
- Configurations: hinged, sliding, bi-fold, and fixed panels
- Finishes: full powder-coat colour range, including marine-grade coatings for coastal exposure
- Operation: tilt-rod or clearview (hidden) tilt
- Suitable for interior privacy, exterior weather screening, and security applications

## Applications

- Exterior window and patio screening — full weather and sun exposure
- Coastal homes — Knysna lagoon-front and Plettenberg Bay where salt air corrodes timber and standard hardware
- Security shutters — lockable aluminium panels over doors and windows
- Bathrooms, kitchens, and pool areas — moisture-resistant where timber would warp
- Commercial façades and patios requiring durable, adjustable shade

## Coastal Specification

Duncan Kane specifies marine-grade powder coating and corrosion-resistant fittings for all coastal aluminium shutter installations. The Garden Route's combination of salt air and prevailing south-westerly wind degrades under-specified hardware quickly. Frame gauge, fixing method, and coating grade are assessed at the site before manufacture.

## Who This Is For

Aluminium shutters are for Garden Route homeowners and businesses who need shutters that survive coastal exposure — exterior positions, salt air, high UV, or security requirements — where timber would fail. They are also the right choice for moisture-heavy interior rooms. Aluminium shutters require a site measure and are not sold online.
