Common Challenges with Solar Roof Rivet Joints
In the practical use and installation of solar roofs, there are various difficulties and challenges. The following are some of the challenges that a solar roof project may face.
- Corrosion Hazards Between Aluminum and Steel Structures
- Loose rivets under wind load / vibration
- Seal failure leading to water penetration
- Aesthetically pleasing, concealed mounting of the module surfaces
- Tight roof construction space makes installation difficult
Rivmate is designed to meet these challenges.
Rivmate Solar Roof Fasteners Solution Highlights
Whether you are faced with a colored steel tile connection, BIPV aluminum tile assembly, cable guide installation, or Tracker Roof System wind-resistant connection, Rivmate offers an all-in-one Solar Roof riveting solution that provides structural fit + material fit + corrosion protection verification + guaranteed installation efficiency.
Rivmate offers a complete line of structural rivets for all scenarios from primary load-bearing connections to secondary component assembly. Included:
- Closed-End Blind Rivets: Closed end design prevents moisture ingress and is suitable for sealed areas.
- Tri-Fold Rivets: Low point pressure design protects aluminum, composite panels and other deformable materials.
- Bulb-Tite Rivets: Compatible with multiple panel thicknesses, wide installation tolerances, easy construction
- Monobolt / Lockbolt (structural rivets): high tensile and shear strength, suitable for the main bracket connection or wind load resistance requirements of the site
For different structural materials (e.g. aluminum profiles, galvanized steel, color steel tiles, stainless steel parts), Rivmate offers a wide range of material combinations:
Aluminum body + stainless steel core: for aluminum frame and rail connections.
Galvanized steel body: for steel roofs, offering Dacromet treatment for corrosion protection.
All Stainless Steel Construction: Suitable for seacoast, high salt spray, high humidity areas, with a maximum life span of 25+ years.
📌 All product materials have passed RoHS / REACH environmental compliance testing
Applied in the solar roof blind rivets are basically closed structure. And it has good waterproof and rustproof characteristics. Therefore, it can improve the IP rating of soalr system.
The end of solar roof rivets is basically closed design. This design can effectively prevent water vapor infiltration and mandrel detachment. This makes it ideal for use in critical areas such as electrical boxes, drain boards, vents, etc.
In addition, the closed design prevents the mandrel from falling into the component or bracket, eliminating the potential for structural noise.
Auxiliary lift assembly/system as a whole IP65/IP67 protection rating
✔ High strength structural reliability, passed international standard test
All structural rivets of Rivmate have passed ISO 14589 / DIN 7337 mechanical standard verification.
Besides, we can provide corresponding samples for your solar roof project. And we can provide the shear force and tensile force test data.
If you want to customize structural rivets for your solar business, Rivmate can also carry out FEM analysis and engineering stress calculation according to your rivet drawings.
Rivmate Solar Roof Rivet Fasteners Applications
In actual solar roofing systems, different joints place very different demands on rivet construction, material, waterproofing capabilities and installation methods. Rivmate offers specialized rivet types and construction recommendations for each type of roof structure and functional area to achieve a balance of high reliability, long life and construction efficiency.
Bracket base → color steel tile or steel purlin fixing
- Scenario Description: The bottom of the rail connects to the main body of the roof and is the structural main connection that carries the wind load and gravity.
- Recommended Rivet Type: Monobolt or Lockbolt
- Structural advantages: high shear and tensile strength, mechanical locking of the mandrel, anti-loosening, anti-vibration, suitable for high wind pressure areas and large-scale component systems.
Side / Middle Press → Hidden fixing inside the aluminum frame
- Scenario Description: To enhance the aesthetics of the roof assembly or for concealed burglary protection needs, the inside of the press block is pre-assembled via rivets.
- Recommended Rivet Type: Flat-head Closed-End Rivet
- Structural advantages: flat surface after riveting, the mandrel is not exposed, to prevent potential corrosion, disassembly is difficult, to enhance the appearance of the system integration
Cable guide bracket, cable tray, raceway → Guide rail attachment fixing
- Scenario description: a large number of widely distributed, the installation of high efficiency requirements, but the bearing capacity is medium
- Recommended rivet type: Multi-Grip or Bulb-Tite Rivet
- Structural advantages: Adapt to different board thicknesses, large tolerance. Soft expansion zone, no damage to accessory materials. Fast installation, suitable for on-site construction or pre-assembly.
Drainage board, lower sealing board, ventilating shell → Sealing joints
- Scenario description: riveted joints are susceptible to rain, moisture erosion, need to maintain long-term sealing and waterproofing
- Recommended Rivet Type: Closed-End Blind Rivet
- Structural advantages: no through holes after riveting, the mandrel is completely locked, no water seepage or corrosion, to meet the IP65/67 sealing requirements of photovoltaic systems.
BIPV Roofing System → Connection of metal tiles to internal keel
- Scenario description: aluminum tiles, composite panels and other thin-walled materials, the connection part of the structure of light and frequent thermal expansion and contraction
- Recommended Rivet Type: Tri-Fold Rivet or Bulb Tite Blind Rivets
- Structural advantages: rivet tail tri-fold unfolding, dispersion of clamping pressure, to prevent rupture of the plate, enhance the contact area. And the installation is smooth, suitable for aesthetic requirements of high building photovoltaic systems
FAQs about Solar Roof Rivet Fasteners Solutions
1. What types of roofing structures are Rivmate's rivets suitable for?
A: Rivmate’s rivet products are suitable for a wide range of roofing systems. These include color steel tiles, galvanized steel, aluminum tiles, composite metal roof panels, and building-integrated BIPV metal structures. Whether it’s a lightweight bracket, sealed underlayment, or heavy-duty rail system, there is a matching rivet model available.
2. If my bracket material is aluminum and the butt joint is galvanized steel, how should I select rivets?
A: To avoid galvanic corrosion between aluminum and steel, it is recommended to choose aluminum body + stainless steel core or Dacromet-treated steel rivets. At the same time, you can add anti-corrosion adhesive cushion layer at the contact interface to further extend the service life.
3. Are the rivets supplied by Rivmate waterproof and rustproof?
A: Yes. Our Closed-End Blind Rivets are designed to be waterproof. It has a completely closed end and a locking mandrel, effectively blocking water vapor from entering the system. All products have passed ≥240 hours of salt spray test, some models up to 1000 hours or more, suitable for medium to high corrosive environments.
4. Does Rivmate provide samples and drawings?
A: Yes. You can request a free sample kit with corresponding 2D drawings and 3D model files. A product selection manual and salt spray/mechanical test report are included for inclusion in the bracket system drawing or structural review process.
5. Do I need to use specific tools to install Solar Roof rivets?
A: Rivmate’s rivets are compatible with all major pneumatic and electric rivet guns on the market. We can recommend the appropriate tool model, air pressure setting and core break pull force range based on the rivet model you are purchasing, as well as provide installation work instructions (SOPs) and operation videos.
