In terms of the choice of clip material on the back of the LED aluminum profile, transparent plastic and metal materials have their own characteristics.
The main differences are the following aspects:

Durability and Strength:
Metal clips (such as aluminum alloy,stainless steel)
Advantages: High tensile strength,wear resistance,not easy to deform after long-term use,suitable for load-bearing or frequent disassembly scenarios.
Disadvantages: The lifespan may be affected by metal fatigue or oxidation( such as rust on stainless steel), and the weight is slightly larger.

Transparent plastic clips (PC,ABS)
Advantages: light weight,good impact resistance( especially in low temperature environment),insulation and no corrosion risk
Disadvantages: Long-term exposure to ultraviolet rays may cause aging and brittleness, and has low load-bearing capacity.

Environmental adaptability

Metal: High temperature resistance( such as high temperature outdoor environment), but conductivity may be risky in humid scenes.
Plastic: Acid and alkali resistant, non-conductive,suitable for humid or chemical environments, but may soften at high temperatures (PC temperature resistance is about 120°C, ABS about 80°C)

Installation and Maintenance

Matel clips: usually requires tools to install (such as screws), which is a bit troublesome to remove, but the connection is more stable
Plastic clips: Most of them adopt clips design, which is easy to install(hand operation) and suitable for fast construction, but may become loose due to repeated disassembly.

Cost and aesthetics:
Plastic : low cost, transparent design may be more concealed, suitable for occasions with high aesthetic requirements,
Metal: More expensive, but more industrial-looking, suitable for high-end or heavy-duty applications.

Special needs:

Insulation: Plastics are suitable for scenarios with high electrical safety requirements.
Thermal conductivity: Metal may indirectly assist in heat dissipation, but has limited effect on LED heat dissipation
