The company produces compression, extension, torsion, and disc springs across thousands of stocked sizes and variants, manufactured from materials including 302/316 stainless steel, music wire (ASTM A228), high carbon steel (ASTM A227), chrome vanadium, and 17-7 PH stainless steel. Core product lines include conical, metric, polywave, precision, and ultra-precision compression springs; utility, precision, ultra-precision, and specialty extension springs; Belleville, metric Belleville, ball bearing pre-load, curved, finger, wave, and serrated safety disc springs; and single/double torsion springs. Custom spring design and prototyping services are offered alongside the catalog, supported by engineering assistance for load, torque, and material selection.

The business operates a sales-led B2B and B2C model: revenue is generated through one-time catalog sales from stocked inventory, custom manufacturing orders priced via quote, and retail spring assortments for DIY customers. Distribution runs through a direct e-commerce storefront at gardnerspring.com (with TraceParts-integrated CAD downloads), toll-free and local phone ordering, and direct sales to OEMs and industrial suppliers, with Net 30 terms available to qualified business accounts.
