No Sag Metal Zigzag Snake Shape S Spring For Sofa
Products Descriptions
Material: High-Carbon Steel (typically 65Mn in China, which is similar to 1065 or 1070 steel). This provides excellent springback,
durability, and resistance to permanent deformation.
Wire Diameter: 3.8mm (This is a standard, heavy-duty gauge. Lighter sofas might use 3.2mm, while this 3.8mm is for robust,
daily-use sofa beds).
Surface Treatment:
Electro-Galvanized: A shiny, silver-zinc coating that provides good rust resistance for indoor furniture.
Phosphated (Black): A dark, matte coating that offers excellent corrosion resistance and is ideal for paint adhesion.
Function: To provide the primary suspension and support for the seat of a sofa bed, distributing weight evenly and allowing for the
folding mechanism to work smoothly.
