The Good Quality Heavy Duty Flat Spring offered by Xiangtan Spring Factory Co., Ltd. is a custom‑manufactured spring bar with wire diameters ranging from 1 mm to 100 mm, an outside diameter up to 500 mm and a free length that can reach 1 200 mm. The number of active turns is made to order, allowing any coil count required by the application. Surface treatments include dipping paint, shot peen, zinc plating, nickel plating, chrome plating, gold plating, copper plating, spray‑paint, e‑coating, powder painting and oil tempering. Minimum order quantity starts at 100 pieces and the supplier welcomes smaller trial batches.
The springs are typically fabricated from high‑carbon steel, which provides the tensile strength and fatigue resistance needed for heavy‑duty service. Standard heat treatment followed by the selected surface finish ensures corrosion resistance and wear durability. In the spring market, a wire diameter of 1‑100 mm covers everything from precision instrumentation to large‑scale mechanical suspensions, while an outside diameter of up to 500 mm accommodates broad mounting scenarios.
Typical applications include railway vehicle bogies, freight car suspensions, mining locomotives, heavy‑duty trucks and agricultural machinery, where reliable load bearing and vibration damping are critical. OEMs of rail equipment, heavy‑equipment manufacturers and original equipment suppliers commonly source these springs for custom designs. The supplier states a delivery window of 15‑30 workdays after order confirmation, with payment on a 30 % deposit and balance before shipment; packaging is supplied in inner plastic bags within outer cartons or wooden cases as requested.
