Rectangular Springs

Rectangular springs emerged during the European Industrial Revolution in the 1960s, originally developed to address spatial constraints in heavy machinery and automotive suspension systems. Compared to traditional round-wire coil springs, rectangular springs offer two core advantages: they provide higher load-bearing capacity (approximately 30% greater) and more stable mechanical performance under equivalent load conditions, while reducing required installation space by up to 40%. This makes them ideal for applications with strict volume and performance demands. Initially used primarily in industrial equipment and automotive systems, their use has since expanded into various high-precision industries.

Variants
Single-body rectangular coil springs, stacked or nested rectangular spring assemblies, rectangular-wire compression springs, special-profile rectangular springs (e.g., tapered or wave-end designs).

Application Fields
Since the 21st century, rectangular spring applications have extended from their original heavy-duty industrial roots into numerous high-precision sectors. Typical uses now include the automotive industry, aerospace, electronics, machinery, construction, and energy systems.
