Services
WSS Elevated Racking
Our WSS Elevated Racking System addresses equipment-loaded rooftops with space constraints. This UL 2703-certified solution mounts directly over HVAC units or bearing walls while distributing structural loads through spreader beams. Ideal for service stations and commercial buildings requiring high-capacity installations without roof penetrations.
PSS Racking System
The PSS Racking System solves structural challenges for rafter-style rooftops in multi-family housing and hotels. This elevated solution anchors to roof rafters near central corridors while maintaining clearance for rooftop equipment. Features modular components that simplify installation across wood-framed structures.
FSS Flushmount System
FSS Flushmount Systems provide secure solar installations on tilt-up walls and low-slope roofs. Our patented SureGrip clamp technology enables beam attachment without drilling, preventing fire hazards. This system maximizes ground coverage while maintaining minimal visual profile for commercial applications.
AFSS A-Frame System
The AFSS A-Frame system delivers standalone solar arrays for commercial properties with ground space limitations. This modular design features adjustable tilt angles for optimal solar exposure and integrates with concrete or pile foundations. Engineered for rapid deployment in industrial and agricultural settings.
FSS Awning Racking
Our FSS Awning System extends rooftop solar capacity by attaching to parapet walls. This non-penetrating solution preserves roof warranties while creating additional mounting space. Designed for tilt-up concrete structures, it combines structural stability with aesthetic integration for commercial buildings.
