Efficiently manages rainwater to keep interiors dry
Anti-slip stainless steel grate meets AS 4586 safety requirements
FlowTHRU™ Pro is an advanced integrated drainage system designed to simplify installation while achieving a flawless, flush threshold for sliding doors. Engineered for 2- and 3-track systems, it allows both internal and external floor surfaces to align seamlessly — creating the clean, uninterrupted transition homeowners love without the raised sill or tripping hazards traditionally associated with door thresholds.
With its single-level setdown, FlowTHRU™ Pro is ideal for homes built on suspended slabs or multi-storey projects where slab depth is limited. This innovation reduces installation complexity, maintains slab integrity, and delivers a premium architectural finish suited to contemporary Perth homes.
With three grate options available: aluminium, stainless steel or a tile insert that blends perfectly with your chosen flooring. The stainless steel grate includes an anti-slip surface compliant with AS 4586, ensuring safety without compromising aesthetics. The aluminium grate can also be powder-coated or anodised to match your home’s colour palette.
FlowTHRU™ Pro is the ideal solution for homeowners seeking a high-performance drainage system that enhances aesthetics, accessibility and everyday functionality — all while supporting the long-term durability of their door and flooring systems.
