Custom Steel Sofa Spring Zigzag Chair For Industrial Hardware Use Furniture Accessory
Products Descriptions
Material: Ensure it's High-Carbon, Heat-Tempered Steel. This is non-negotiable for durability.
Finish: A good Galvanized or Painted Finish (often red or green) is crucial to prevent rust, which can weaken the spring and
stain fabric over time.
Consistency: The bends in the zigzag pattern should be uniform and smooth, without any sharp kinks or cracks in the metal.
Reputable Supplier: Source from specialized upholstery supply houses or well-known hardware retailers that cater to professionals.
