Commercial Roof Mounting Systems for Every Structure
WANHOS supplies project-specific PV roof mounting systems for commercial, industrial, and utility-scale installations. The core function of any roof mounting system is to create a secure, durable interface between the solar array and the building envelope, transferring all static and dynamic loads into the roof structure without compromising waterproofing or structural integrity.
Our systems coordinate three essential functions: secure roof connection, load transfer, and module alignment. Each roof type—tile, metal, or flat—requires a different connection logic, but the engineering goal remains the same: a reliable, code-compliant foundation for the PV array.
- Secure roof interface: non-destructive or penetrating fastening matched to roof material.
- Load transfer: engineered rails and connections distribute wind, snow, and dead loads into the building structure.
- Module alignment: pre-assembled components and adjustable brackets ensure straight rows and optimal tilt.
Tile, Metal, and Flat Roof Solutions
WANHOS coordinates complete mounting assemblies for the three most common commercial roof types. Each solution is built around a specific connection logic, with compatible rails and clamps to form a unified system.
Tile Roof Systems
Non-destructive hook-on brackets clamp onto the roof structure without penetrating tiles. Custom geometry (a/b/c dimensions) is available through CAD-based design to match the exact tile profile and batten spacing. SUS304 stainless steel ensures long-term corrosion resistance.
Metal Roof Systems
Coordinated L-foot and rail assemblies attach to standing seam or corrugated profiles. The system provides a common rail platform for module clamps, simplifying large-scale installations. Pre-assembled tilt-in modules reduce on-site labor and improve installation consistency.
Flat Roof Systems
Ballasted or anchored tripod structures support low-slope roofs. Tilt angles from 5° to 30° enable optimal solar yield without roof penetration. Ballast configuration is calculated based on project wind and snow loads.
Specify with the Whole Roof in Mind
Roof mounting is not a catalog item; it is a structural interface. WANHOS treats each project as a unique set of site conditions: roof slope, building height, local wind region, and snow exposure all influence the final system design.
Our engineering process evaluates the load path from module to roof structure. We provide calculations and design references based on international standards such as AS/NZS 1170 and EN 1991, ensuring that the system remains within acceptable stress limits under all relevant load combinations.
- Wind actions: uplift and downforce calculated per project location and building geometry.
- Snow actions: conversion of snow depth to roof load, with appropriate safety factors.
- Connection verification: pull-out and shear capacities checked for each fastener type.
- Adjustable pitched roof mounts: custom angle adjustments for irregular roof slopes.
Factory-Direct Supply for Global B2B Partners
WANHOS manufactures roof mounting components in our own facilities, supporting OEM and ODM programs for EPCs, distributors, and project developers worldwide.

Documentation and Compliance Support
For commercial procurement, confidence comes from verifiable documentation. WANHOS provides the technical files that engineers and procurement teams need to approve a system.
Upon request, we supply CAD drawings, material data sheets, installation manuals, and test reports relevant to the selected components. Compliance documentation is available for review by your project team.
- 2D/3D CAD files for integration into project drawings.
- Material certificates for aluminum and stainless steel components.
- Mechanical test data for critical connections.
- Installation guidelines for site crews.
Project Delivery Support
From order confirmation to container loading, WANHOS coordinates logistics to keep your project on schedule.
We sequence production to match your construction timeline and pack kits by roof zone or array block, reducing on-site sorting time. Our export team handles documentation, labeling, and shipment tracking.
- Kit packaging per project phase.
- Pre-assembled components where practical to reduce labor.
- Shipping documentation for customs clearance.
- Clear labeling for quick identification on site.
Frequently Asked Questions
What roof types does WANHOS support?
We supply mounting systems for tile, metal (standing seam and corrugated), and flat roofs. For each type, we offer both standard and custom configurations.
Can you provide custom dimensions for specific tile profiles or metal seam spacing?
Yes. We use CAD-based design to match the exact geometry of your roof. You can send tile profile drawings or seam measurements, and our engineers will produce a custom bracket or L-foot.
How does WANHOS handle wind and snow load verification?
We calculate loads based on project location, building height, and roof slope using international standards as a reference. The resulting design is verified against mechanical test data for critical connections.
What documentation do you provide for procurement?
We provide CAD files, material data sheets, installation manuals, and available test reports. Compliance documentation can be reviewed before order confirmation.
Do you offer OEM/ODM services?
Yes. We manufacture under your brand or develop custom designs based on your project requirements. We support project-specific BOMs and packaging.
What is the typical lead time for roof mounting orders?
Lead times depend on order volume and customization. Standard systems can be produced and shipped within a few weeks; custom projects are scheduled during quotation.
