Import Bonnel Springs — Buy in Bulk from Supplier in Turkey

Bonnel springs from Ozdemir Malzeme Ltd Sti are helical coil springs made from carbon steel, with standard diameters of 82 mm, 86 mm, 91 mm, and 92 mm, and a consistent height of 14 cm as listed. Each spring is wound to maintain uniform tension and is heat-treated for resilience under repeated load. These dimensions align with common industry standards for mid-to-high-end mattress cores, where coil diameter directly affects firmness and weight distribution.

The springs are constructed from low-carbon steel wire, typically in the 1.8 mm to 2.2 mm gauge range, which is standard for durable mattress cores. Surface treatment is not specified but is commonly galvanized or epoxy-coated in industrial practice to prevent corrosion. The coil structure follows the traditional Bonnel design: interconnected in a continuous helical pattern, allowing for even load transfer across the mattress surface. This construction differs from pocketed springs by offering a more unified support system preferred in traditional innerspring mattresses.

These springs are sourced primarily by mattress manufacturers in Europe and the Middle East seeking reliable components for budget to mid-tier bedding lines. Buyers typically order in full container loads, with roll packing used to optimize space in shipping containers. The springs are delivered unpackaged or in bulk polyethylene wraps, and lead times depend on production cycles. Trade terms are commonly FOB Istanbul or port of loading, with payment via LC or T/T confirmed against shipping documents.

Ozdemir Malzeme Ltd Sti operates from the 1.Organize Industrial Zone in Kayseri, Turkey, a region known for metal fabrication and mattress component manufacturing.
