Foundation & Anchoring Solutions

Steel Base Kit (Optional Upgrade): Planning to install in a windy or extreme environment? Grandio recommends the proprietary Steel Base Kit for maximum stability. This powder-coated steel system resists rust and corrosion while adding significant strength and rigidity to your greenhouse. As a bonus, it creates an additional 3″ of headroom. Each Steel Base Kit includes your choice of specialized anchors for earth/soil, concrete slab, or wooden decking installations. Frame-to-Base Brackets available for enhanced security.

Flat Mount Anchor Kit (Included): Installing on a concrete slab or wooden deck in a protected, fenced environment? The included Flat Mount Anchor Kit provides reliable anchoring with your choice of fasteners for concrete or wood applications. Note: Ground installations require the Steel Base Kit upgrade for proper anchoring.

Unmatched Warranty Protection

Our lifetime frame warranty and 10-year panel warranty represent more than peace of mind – they’re our commitment to exceptional quality, dependability, and reliability. Every Grandio Greenhouse is precision-manufactured to meet rigorous standards and engineered to withstand extreme wind and weather conditions.
