M-Type PV Drainage Gutter

Chudu Metal Zn-Al-Mg Coated Steel Solar PV M-Shaped Main Drainage Gutter is a primary rainwater collection and drainage component designed for BIPV roofing, solar carports and waterproof photovoltaic mounting systems.

Brand: Chudu Metal

Product Information

1. Product Overview

As the main drainage channel of the waterproof PV system, the M-shaped gutter receives rainwater collected by transverse sub-gutters, U-shaped drainage channels and other auxiliary water-guiding components. The collected water is then guided longitudinally along the photovoltaic structure toward the designated drainage outlet or downpipe.

Manufactured from Zn-Al-Mg coated steel, the M-shaped main gutter provides reliable structural performance and corrosion protection for long-term outdoor photovoltaic applications.

Different gutter widths, heights, sheet thicknesses, lengths and cross-sectional profiles can be customized according to customer drawings, solar module layouts, mounting structures and project drainage requirements.

2. Key Features

M-Shaped Main Drainage Design

The specially formed M-shaped cross-section creates a continuous main drainage path for waterproof photovoltaic mounting systems, allowing rainwater from multiple auxiliary drainage points to be collected and discharged efficiently.

Main Rainwater Collection

The M-shaped gutter serves as the primary water collection channel of the system, receiving water from transverse sub-gutters, U-shaped sub-gutters and other auxiliary drainage channels.

Longitudinal Water Drainage

The long-profile structure guides collected rainwater along the photovoltaic array toward the designed drainage outlet, downpipe or project-specific discharge point.

Zn-Al-Mg Coated Steel

The zinc-aluminum-magnesium coated steel surface provides corrosion protection suitable for outdoor BIPV structures, solar carports and waterproof solar mounting applications.

Compatible with Sub-Gutter Drainage Systems

Designed to work together with U-shaped sub-gutters, transverse drainage channels, auxiliary gutters and other waterproof PV components to form an integrated rainwater collection and drainage system.

Continuous Formed Structure

The continuous long-profile design helps provide a stable drainage path and can be manufactured in different lengths according to project layout.

Multiple Size Options

Different section widths, gutter heights, sheet thicknesses and lengths are available according to waterproof system design and drainage capacity requirements.

OEM & Customized Manufacturing

Cross-sectional dimensions, material specifications, sheet thickness, gutter length, edge structure and connection details can be customized according to customer drawings and samples.

5. M-Shaped Main Drainage Structure

The M-shaped gutter is designed as the main longitudinal drainage component within a waterproof photovoltaic mounting system.

Rainwater collected by smaller transverse or auxiliary gutters is transferred into the M-shaped main gutter. The main gutter then receives water from multiple drainage points and guides it continuously toward the final drainage outlet.

This drainage structure is suitable for photovoltaic projects where organized water collection and controlled rainwater discharge are required.

6. Water Drainage Principle

1. Rainwater Collection at Module Joints

Rainwater entering through the joints between adjacent solar modules is collected by transverse sub-gutters, U-shaped drainage channels or other auxiliary water-guiding components.

2. Water Transfer to the Main Gutter

The collected rainwater is directed from the sub-gutters into the M-shaped main drainage gutter.

3. Longitudinal Main Drainage

The M-shaped main gutter receives water from multiple drainage points and guides it longitudinally along the photovoltaic mounting structure.

4. Final Water Discharge

The collected rainwater is finally directed toward the designated drainage outlet, downpipe or other project-specific rainwater discharge system.

Drainage Flow:

Solar Module Joint → Sub-Gutter / Auxiliary Gutter → M-Shaped Main Drainage Gutter → Drainage Outlet / Downpipe
