Membrane Flat Roof PV Mounting Systems: Ballast-Free Hot-Air Welded Solutions
Hot-air welded directly onto commercial TPO and PVC roofing membranes, eliminating heavy concrete ballast and solving structural load limits on logistics hubs.
Membrane & Lightweight Roof Solar Mounting System: Complete structural mounting assembly engineered for flat membrane roofs (tpo, pvc, epdm and multi-layer bituminous lightweight roofs). Manufactured from certified EN AW-6063 T66 or 6005A T6 aluminum alloys with minimum 15µm Qualanod architectural anodizing. Safely absorbs dynamic wind uplift and heavy snow compression loads while guaranteeing 100% weather tightness and preserving roof building warranties.

Field & Engineering Micro-Answers
Direct structural engineering answers to the most searched Google questions regarding Lightweight Membrane System
What makes this system superior to traditional ballasted racks?
Traditional ballasting adds 15–25 kg/m² of heavy pavers. Our membrane-welded solution requires zero concrete weight, enabling PV on low-load roofs.
Does hot-air welding compromise the building roof warranty?
No. Base sleeves use the exact same TPO or PVC material approved by major membrane makers, creating a permanent homogeneous waterproof seam.
What wind uplift speeds can welded membrane anchors resist?
Tensile peel tests prove the welded bond withstands up to 180 km/h wind suction before sheet tear, exceeding standard ballasted pavers.
Can sections be dismantled for localized roof repairs?
Yes. Aluminum rails bolt onto the welded bases. Individual modules and rails can be removed in minutes without cutting the underlying membrane.
Which membrane materials are compatible?
Compatible with TPO, PVC, EPDM, and modified bitumen membranes using corresponding factory-applied weldable flanges.
How does this speed up site logistics and construction?
Eliminating hundreds of tons of concrete pavers eliminates crane hoisting costs and shortens installation schedules by over 60%.

Why EN AW-6063-T6 Structural Aluminum Over Hot-Dip Galvanized Steel?
Photovoltaic mounting structures are 25 to 30-year infrastructure assets. Specifying extruded aluminum over heavy galvanized steel delivers decisive advantages in structural rooftop safety, installation speed, and zero lifetime maintenance.
| Engineering Criterion | SolarAlu 6063-T6 / 6005A Anodized Aluminum | Hot-Dip Galvanized Steel (HDG) |
|---|---|---|
| Specific Weight & Rooftop Dead Load |
2.70 g/cm³ (~1.8 - 2.5 kg/m² structural load)
3x lighter than steel; preserves structural load reserves on large-span industrial roofs without expensive building reinforcement. |
7.85 g/cm³ (~6.0 - 9.0 kg/m² structural load)
Heavy dead weight; frequently violates building deflection limits on lightweight sandwich and trapezoidal roofs. |
| Atmospheric Corrosion & Lifespan |
25+ Years Maintenance-Free (Qualanod 15µm/20µm)
Forms an impervious self-healing aluminum oxide layer; zero corrosion in marine seaside (C4/C5) and industrial chemical atmospheres. |
Corrosion Initiates within 5–8 Years
Field cutting and bolt drilling damages the zinc barrier layer; rust run-off stains PV glass and demands periodic repainting. |
| Installation Speed & Labor Cost |
45% - 50% Faster Job Site Assembly
Pre-engineered T-Slot channels allow rapid snap-in fasteners; zero on-site cutting, zero welding, and minimal crane hoisting required. |
Heavy Labor & Slower Progress
Heavy manual lifting on roofs, complex multi-piece bolting, and awkward alignment double the on-site mechanical installation labor hours. |
| Galvanic Compatibility with PV Modules |
100% Metallurgical Compatibility
Solar module frames are also manufactured from anodized aluminum; zero electrical potential difference, preventing bimetallic contact corrosion. |
Bimetallic Galvanic Cell Risk
Direct steel-to-aluminum contact forms a galvanic cell in humid conditions, corroding the module frame and voiding panel warranty. |
| End-of-Life Residual Asset Value |
80% - 85% Scrap Residual Value
Aluminum is infinitely recyclable without property degradation, representing a liquid financial asset at decommissioning. |
Low Residual Scrap Value
Corroded steel scrap value is negligible and often does not cover the crane and disassembly labor costs. |
