What Are PV Mounting Gutters?
PV mounting gutters are specialized drainage components integrated into solar mounting systems. Their primary function is to efficiently divert rainwater, preventing water accumulation that can corrode photovoltaic modules and mounting structures. They are essential for applications where waterproofing is critical, such as solar carports and rooftop installations.

Production Process – Screw Piles Technical Parameters
Step 1: Raw Material Preparation
Qualified ZAM (Zn-Al-Mg) coated steel coils are selected and inspected. Material grade and coating thickness are verified to ensure compliance with specifications.
Step 2: Cold Roll Forming
The ZAM-coated steel strip is fed into a precision cold roll forming unit. Through progressive roller stations, the strip is gradually shaped into the required gutter profile (M-shaped, U-shaped, or custom).
Step 3：Cutting
Profiles are cut to customer-specified lengths using automatic cutting equipment. Length tolerance is strictly controlled to ensure precise fit on-site.
Step 4：Packaging
Qualified gutters are bundled, labeled, and packaged per order requirements. Protective materials are used to prevent surface scratches during transportation. Packed goods are stored in warehouse ready for shipment.
