U Clamp
- Product Type: Solar panel mounting
- Product Model: SPC-RC
- Material: Aluminum/S350GD-ZM/Q235B
Net weight: 0.25KG - Max Wind Load : 60 m/s
Max Snow Load : 3.6 KN / M 2
Product Description:
Our high-quality U clamps are widely used in solar installations. They perfectly secure M channels and are also suitable for securing U rail and square tube. Made of high-quality AL6005-T5, S350GD-ZM, and Q235 materials, these clamps are durable and provide a tight fit, securing the channel and preventing loosening.
The U clamp consists of four parts:
M channel aluminum clamp
Plate
U bolt
Nut
Features:
High dimensional accuracy
Sturdy construction
Corrosion resistance
Withstands harsh weather conditions
High load capacity
Impact resistance
Reusable
Installation steps:
Firstly, secure the U-shaped bolt to the square tube, press the M channel with the clamp, and adjust the position.
Secondly, tighten the bolt with an electric wrench.

SPC‑RC Solar U‑Clamp Frequently Asked Questions
1.Q:Can I reuse the SPC‑RC solar U‑clamp after disassembly?
A：Yes, it is reusable if no deformation, crack or thread damage. Avoid repeated excessive over‑torquing.
2.Q:What torque should I use for tightening the U‑bolt?
A：Recommended tightening torque is 18‑22 N·m. Impact wrenches without torque adjustment are not recommended.
3.Q:Can this U‑clamp work in coastal salt‑spray environment?
A：Standard hot‑dip galvanized version supports normal coastal projects. For severe salt‑spray areas, we offer optional stainless‑steel U‑bolt upgrade.
4.Q:Is OEM / custom modification available for SPC‑RC U‑clamp?
A：Yes, OEM is supported, including custom marking, surface treatment, special packing. Contact our sales team for drawings and MOQ.
5.Q: Can you provide technical drawing file for engineering review?
A：We can supply drawing upon project inquiry.
6.Q: What is MOQ for solar U‑clamp SPC‑RC?
A：Small trial orders are acceptable, MOQ depends on packing requirement. Please send inquiry with your quantity.
7.Q:Can I install this U‑clamp SPC‑RC without pre-drilling holes on the steel tube or M channel?
A：Yes. This is a non-penetrating clamping solution. No drilling or welding on profiles is required, which keeps the structural strength of the support intact.
8.Q:Which solar project types is this U‑clamp SPC‑RC used for?
A:Our U clamp is widely used in metal roof solar mounting, ground mount solar systems, and carport solar installations. It secures M channel or U rail to the underlying structure and is compatible with framed PV modules 30-50 mm thick.
9.Q:How many sets of U‑clamp SPC‑RC are generally needed per MW of ground mount solar system?
A: The consumption quantity depends on the layout of M channel and square tube. Please send your racking layout drawing, and our engineering team can calculate the exact quantity for you.
10.Q:How does U‑clamp SPC‑RC compare to L feet for metal roof mounting?
A:L feet are typically used at the end of rails for portal-frame metal roofs and have a low profile. U clamps secure M channel and U rail to underlying structures and offer a tighter, more rigid connection — preferred for ground mount and high-load applications. Send us your project drawings and we’ll recommend the right option.
11.Q:How to fit a U clamp?
A:Four-step installation: (1) Place the M channel or U rail on the structural square tube in the planned location.
(2) Slide the U-bolt through the pre-drilled slot of the channel and around the square tube.
(3) Add the backing plate and stainless steel spring washer on the threaded ends.
(4) Tighten the two M8 hex nuts gradually torque.Do not over-torque
12.Q:What size square tube is this U Clamp for Solar suitable for?
A:It’s suitable for 40*60/40*80/50*100/100*100mm square tube.
13.Q:What are its applicable scenarios?
A:It is widely applicable in the photovoltaic field, construction industry, shipbuilding industry, machinery and electronics industry, and bridge industry, etc.
