1. What is the zinc-aluminum-magnesium M channel waterproofing solution?
TBS’s zinc-aluminum-magnesium M channel waterproofing solution protects solar installations from rainwater leakage. This system combines an M-shaped channel with U-shaped auxiliary channels and fixing clamps to securely mount solar modules while preventing water intrusion.
2. Where is this solution applicable?
Primarily designed for three scenarios:
-
Residential solar sunrooms
-
Commercial/industrial factories with metal roofs
-
Steel or aluminum carports
3. How does the M channel waterproofing work?
During rainfall, most rainwater flows directly off module surfaces into front water tanks. Meanwhile, any water seeping between modules gets captured by horizontal U-shaped channels. Next, this water transfers into the M channel. Finally, the system directs all water to designated drainage points (e.g., sunroom water tanks), eliminating leaks.
4. What are the installation steps?
Step 1: Secure the M channel to purlins using square tube U-shaped hoops or C-steel clamps.
Step 2: Position U-shaped auxiliary channels between module gaps to collect seepage.
Step 3: Mount solar modules onto the M channel using crossbar clamps or mid-side clamps.
5. How does the M channel differ from W channel solutions?
| Feature | M Channel | W Channel |
|---|---|---|
| Primary Use | Residential sunrooms & steel carports | Aluminum alloy carports |
| Installation | Direct mounting to purlins | Requires L-angles before mounting |
| Shared Use | Metal roof factories (same waterproof principle: main channel + U-channels) |
6. Why choose zinc-aluminum-magnesium material?
Zinc-aluminum-magnesium alloy offers superior corrosion and oxidation resistance. Consequently, it withstands harsh outdoor conditions (rain, snow, humidity) far better than standard materials. This durability significantly extends channel lifespan while reducing long-term maintenance costs for exposed solar installations.
7. Is retrofit possible for existing metal roofs?
Yes. Contractors can retrofit this solution onto aging color steel tile factory roofs. Importantly, the M channel system adds secondary waterproofing protection, effectively resolving leakage issues from roof deterioration.
