Welcome to Silca System NZ: Eco-Friendly Decking Solutions for Sustainable Living

At Silca System NZ, we revolutionize deck design and construction. Our innovative and sustainable solutions provide the perfect choice for your architectural projects, making us a leader in eco-friendly decking solutions in New Zealand.

The Inspiration Behind Silca System NZ

We drew inspiration from the natural efficiency of honeycomb structures used by honeybees. This led to the creation of the Silca Grate. Its hexagonal design and integrated strengthening channels create a super-strong and consistent substructure, effectively spreading load across the decking element and into the joist structure below.

Key Features of Silca Grate

The 50mm diameter cells deliver consistent structural support beneath the entire underside of the tile. This ensures a firm feel underfoot. The Silca System NZ offers a rigid decking element that can sustain heavy materials such as natural stone, porcelain, or concrete pavers. As a result, we provide more decking options than ever before. For your design specifications, we offer Design Statements, PTS, and guides.

Moreover, our Silca System NZ Grates measure 400mm x 450mm x 38mm and are manufactured in New Zealand from 100% recycled materials, making it an eco-friendly construction product.

We compose our grates from an engineered polymer PCABS with UV stabilizer, ensuring durability and longevity. We design our system to meet standards AS/ZNS1170 and NZS3604 and comply with B1/VM1. This guarantees peace of mind for both residential and commercial applications. Additionally, you can achieve permeable site coverage and level entry without needing channel drains or surface fall.

Versatile Applications for Silca Grate

The Silca Grate fits not only elevated decks and patios but also pool decks, rooftop decks over membranes, bridges, stairs, and more. Join us in embracing a new era of decking solutions, versatility, and timeless aesthetic appeal with Silca System NZ.
