Disc-Fixed PV Support

Scope of Application

A through-type PV support specifically designed for TPO/PVC single-ply roofing systems. It features a composite structure of 304 stainless steel and polymer membrane, enabling quick fixation via a four-hole disc and self-drilling screws. The membrane flange of the support is heat-air welded to the main waterproof layer, forming a fully sealed, integrated waterproof assembly with a dual-sealing design. Suitable for supporting PV mounting structures, cable trays, and other roof equipment, it simultaneously addresses structural fixation, waterproof sealing, and wind uplift resistance requirements.

Technical Advantages

• Dual Waterproofing: Combines hot-air welding with water-soluble adhesive film technology for dual protection. If weld seam leakage occurs, the adhesive film activates upon contact with water to automatically seal the leak

• Quick and Efficient Installation: Utilizes standardized discs and self-drilling screws, requiring no complex equipment or procedures, significantly improving installation efficiency

• Stable Structure: The disc distributes load evenly across its four corners, while the central threaded connection forms a stable support system that effectively transfers loads, offering excellent compression and pull-out resistance
