Services
Aluminum Fencing
Our aluminum fencing systems combine wood-like aesthetics with marine-grade durability. Using Knotwood's patented concealed fastening system, we create customizable installations with vertical, horizontal, or diagonal slats. These low-maintenance fences resist corrosion, UV damage, and insect infestation while maintaining structural integrity in harsh coastal environments.
Custom Gates
We fabricate and install pedestrian and driveway gates with cold-weld epoxy corner joints that exceed welding strength. Available in automated or manual configurations, our gates offer security without compromising design flexibility. The aluminum construction ensures longevity in Hawaii's tropical climate while maintaining visual appeal.
Privacy Screens
Knotwood privacy screens balance security and ventilation through customizable slat spacing and angles. Engineered for durability, these screens resist warping and weather damage while providing adjustable privacy levels. The powder-coated finish maintains color integrity for decades under direct sunlight and salt exposure.
Railings
Our aluminum railings enhance property value with wood-grain aesthetics and minimal maintenance requirements. Designed to meet safety standards, these systems resist corrosion in coastal environments while offering design flexibility for residential and commercial applications across Hawaii.
Trellis Systems
Knotwood trellises provide durable, low-maintenance shade solutions with termite-proof aluminum construction. The powder-coated finish resists cracking and fading, maintaining visual appeal for decades. These systems offer design versatility for freestanding or attached structures in residential landscapes.
