L Feet Solar Metal Roof Mounting Systems

Q: Can I use your L‑feet with third‑party solar rails?
A:No. The fixture block is machined to match our own rail profile only, so it does not lock onto third‑party rails.

Q: Do I need to pre‑drill holes on the metal roof sheet?
A: Not necessarily, but we recommend marking the purlin positions first. Our self‑drilling screws can penetrate the metal sheet without a pilot hole, but the screw must reach into the purlin underneath to carry the load correctly. Drilling into the sheet between two purlins will not hold and may cause water leakage. For wood purlins, we supply wood screws and recommend pre‑drilling to avoid splitting the wood.

Q: What is the MOQ for L‑feet metal roof mounting kits?
A: We keep it flexible. Standard L‑feet items can be ordered with a low MOQ of 1000 pcs, so you can test the product before committing to a large quantity. For mixed or customized kits, we will confirm the MOQ based on the configuration. Contact us with your quantity and we will give you the exact MOQ.

Q: What is the lead time for sample orders and bulk orders?
A:Sample orders are usually dispatched within 3–5 working days For bulk orders, the lead time is typically 3-4weeks depending on the quantity and whether the configuration is standard or customized. We will confirm the exact lead time with you at quotation time, and we offer sea, air, and express shipping options.

Q: Can L‑feet be used for thin‑film PV modules?
A:Yes. The L‑feet kit is compatible with both framed and thin‑film (frameless) PV modules. For thin‑film modules, the module is fixed with the appropriate clamps in the same way; the rail and L‑feet configuration does not change. If you are using a module with a non‑standard thickness, confirm the module thickness with us and we will match the correct clamp.

Q: Can I get custom height or custom surface finish for the L‑feet brackets?
A: Yes. We can produce L‑feet with a custom mounting height if your roof geometry or module layout requires it, and we can adjust the anodized surface finish (film thickness and color) on request. Custom versions carry a small setup consideration and a minimum order, so send us your drawing or specification and we will quote accordingly.

Q: Can L feet be reinstalled and reused after roof renovation?
A: Yes. If the L feet are removed without deformation, damage or coating peeling, they can be reinstalled and reused for secondary PV layout adjustment or roof renovation.

Q: Will the silicone rubber pads degrade quickly under strong UV exposure in tropical areas?
A: Our silicone gaskets are UV-resistant and weatherproof. Under normal tropical outdoor conditions, it maintains stable sealing performance for over 10 years, without rapid aging or cracking.

Q: How to calculate the spacing between L feet on the metal roof?
A: The spacing is determined by local wind speed, snow load, solar panel size and roof purlin layout. Our engineering team can provide the recommended layout and spacing drawing once you share your project location and load requirements.

Q: Will installing solar L feet affect the roof’s waterproof warranty of the original building?
A: Standard compliant installation will not affect the building’s original roof warranty. Our full waterproof sealing structure ensures no water leakage
