That's an excellent and very practical question! Yes, noise is absolutely a consideration for metal park benches, and creaking or squeaking over time is a common issue many people notice. However, it's not an inevitable fate for all metal benches. The potential for noise largely depends on the bench's design, construction quality, and maintenance.
Initially, a well-made metal bench from powder-coated steel or aluminum with welded joints should be very quiet. The creaking sound typically develops due to movement between parts. The main culprits are often mechanical joints (like bolts and nuts) that can loosen slightly with constant use and weather exposure. As these parts rub against each other, they create that familiar squeak. Another major cause is corrosion and rust. Even on coated benches, tiny cracks or scratches can let moisture in, leading to rust that creates friction and noise between connected components.
Temperature changes play a role, too. Metal expands in heat and contracts in cold. This constant, subtle movement can stress joints and fasteners, eventually leading to noise if the bench isn't designed to accommodate this thermal flex.
The good news is that this is often a maintenance issue, not a terminal one. Regular inspections to tighten loose bolts and applying a suitable lubricant (like a dry silicone spray) to connection points can silence most creaks. Choosing benches with fully welded frames rather than bolted assemblies can also minimize noise from the start. So, while metal benches *can* become noisy, proper selection and simple care can ensure they remain a quiet, peaceful spot in the park for years to come.
