This product is a photovoltaic (PV) bracket accessory specifically designed for Klip-Lok (standing seam) metal corrugated steel roofs. It employs a non-penetrating clamping structure, eliminating the need for drilling into the roof surface. The clamps secure themselves to the Klip-Lok edge of the roof ridge using their own mechanical locking force, providing a reliable connection point for PV rails or modules. This design avoids damage to the roof panels caused by drilling, effectively reducing the risk of roof leaks, and is particularly suitable for commercial and industrial roofs with high waterproofing requirements.

Product Description
The Klip-Lok clamp is a non-penetrating connector made of aluminum alloy and stainless steel. It clamps and secures the roof without drilling, effectively protecting the roof's waterproofing layer. This product has a wind resistance of ≤60m/s and a snow resistance of ≤1.4kN/m², is easy to install, highly reliable, and durable. It is widely used in distributed photovoltaic projects in industrial and commercial buildings, agricultural greenhouses, and other locations.
Product Components
Advantage
▶ Non-perforated installation
No self-tapping screws are needed, preserving the roof's metal panels and waterproofing layer, significantly reducing the risk of leakage compared to traditional through-hole fixing methods.
▶ Reliable structure
Uniform clamping force, strong wind resistance, and adaptable to high-heat, high-humidity, and salt spray environments.
▶ Easy installation
After the clamp engages with the ridge, tighten with a torque wrench; no special tools required, operable by a single person.
▶ Good compatibility
Adapts to common Klip-Lok ridge sizes; the top interface is compatible with mainstream photovoltaic rails and clamps.
▶ Weather-resistant and durable
The main body is made of anodized aluminum alloy, and fasteners are made of 304 stainless steel, offering a corrosion-resistant lifespan of over 10 years.
▶ Lightweight design
Each clamp weighs approximately 0.15-0.25 kg, reducing roof load.

Applicable Scenarios
▪ Industrial and commercial factory buildings: Large corrugated steel roofs, requiring high standards of waterproofing and construction speed.
▪ Logistics and warehousing centers: Large roof area, suitable for non-perforated installation methods.
▪ Agricultural greenhouses: Metal pitched roofs, clamps can avoid damaging the original structure.
▪ Renovation of old photovoltaic projects: Existing metal roofs cannot be drilled; clamp fixing is the ideal solution.
▪ Buildings with strict waterproofing requirements: Such as factory roofs in the electronics, pharmaceutical, and food industries.
Important Notes:
▶ Roof Type Confirmation
This clamp is only suitable for metal roof panels with a standing seam (Klip-Lok) structure, and not for trapezoidal corrugated panels or angled seam panels.
▶ Load Calculation
The number and spacing of clamps should be calculated by a structural engineer based on local wind speed, snow load, roof span, and other conditions.
▶ Installation According to Specifications
Bolts must be tightened to the specified torque (usually 16-20 N·m) using a torque wrench. Overtightening may damage the ridge, while undertightening may cause slippage.
▶ Roof Condition Inspection
Before installation, ensure the roof panels are free from severe rust, deformation, or coating peeling; otherwise, the clamping force may be insufficient.
▶ Regular Inspection
It is recommended to check the clamp tightness annually, especially after typhoons or heavy snowfalls.
▶ Grounding Connection
If metal rails are used, proper grounding between the components and the roof must be performed according to electrical specifications.
▶ Avoid Mixing
Clamps from different brands or batches may have dimensional variations and should not be mixed on the same roof.
Summary
Klip-Lok Roof Clamps are specialized photovoltaic connectors developed for standing seam metal roofs. Their non-penetrating clamping design avoids the leakage risks associated with drilling, while offering advantages such as quick installation, reliable load-bearing capacity, and strong weather resistance. They are suitable for various industrial, commercial, warehousing, and agricultural greenhouse metal pitched roof photovoltaic projects. With proper selection, standardized installation, and regular maintenance, this product provides a safe, durable, and compliant fixing solution for photovoltaic systems.
