Durable Zinc Plating 3.6mm - 3.8mm No Sag Sofa Springs , Black Color Upholstery Sinuous Springs
Our range of 9 gauge ZigZag Springs (sometimes called Serpentine Springs, Upholstery Springs, Sofa Springs or Furniture Springs) are ideal for re-upholstery projects or replacing broken springs on chairs and sofas.
Zig-Zag Springs are sometimes called Serpentine or No-Sag Springs. These are springs formed from tempered wire, which is then formed into evenly spaced curves or "loops" for a fully supportive seating system. Pitch is measured as the distance between the centre points of one 'U'. Zig Zag Springs should be used with CONNECTING LINKS or similar. Zig Zag Springs are fastened with single metal 'Z' CLIPS or continous plastic CLIP STRIP and can come in ARC or FLAT options depending on the height of 'crown' required and the overall desired appearance.
High tensile strength wire spring, perfectly tempered. Higher gauge springs have thinner wire. Can be cut with bolt cutters. Ready to use. Maximum resiliency is obtained when a convex spring arc height is between 2 and 2 1/4 inches. This is the 'rise'of the spring over the frame mounting point. If you wish to add height to an exisiting spring, use a hinge link at the back of the frame. Spring ends should be cut so that both end face the same direction. When measuring to cut, if the desired length means the ends would face opposite, go to the next longer, not shorter, bend. Sinuous springs, also known as sagless or zig-zag, are the most common low profile springs. Although the shape may lead you to think otherwise, they do depend on compression for the spring effect. A solid and sturdy frame is required to bear the stresses, from the front to back rail and top to bottom rail pull of these springs (occasionally reinforcing is required).
