Why GT MAT
Innovation in the service
of durability
Serious resistance to salt spray
Powder-coated aluminium is recognised for its very high resistance to marine environments. Designed for the islands, it offers remarkable durability against salt air and coastal spray.
Extreme tolerance to tropical humidity
Engineered for the Caribbean environment: tropical rain, high humidity, repeated wet/dry cycles. No warping, no degradation.
Thermal stability
Boards with low thermal conductivity, for a surface that stays comfortable underfoot even in full 35°C island sun.
Maintenance cut to a minimum
No treatment, no protection required. A GT MAT aluminium deck carries no specific maintenance obligation — a rare advantage in our climate.

Why choose an aluminium deck in the Caribbean?
Building a terrace in the islands means choosing a material that can take the tropical climate. Permanent humidity, intense sun, salt spray and termites make traditional decking hard to keep up over time.
Aluminium decking is now one of the most durable answers for outdoor living in the Caribbean. Strong, elegant and free of heavy upkeep, it stands as the high-end alternative to timber and composite.
At GT MAT, we specialise in designing and installing premium aluminium decks engineered for Caribbean weather.

To help you decide
Frequently asked questions
Aluminium conducts heat but stays bearable to the touch — unlike composite, which can become uncomfortable. In a tropical environment some surface warmth is normal. Our light finishes reflect more of the heat.

Frequently asked questions about aluminium decking
Aluminium conducts heat, but the finishes we use limit the temperature rise. Light shades reflect a large share of solar radiation.
