JINHAN produces Minifix Connecting Bolts for furniture with high quality carbon cold rolled steel. We have taken the lead in the industry when minifixes are still being made with zinc alloy globally, so why do we use cold rolled steel to produce them?

When it comes to furniture fittings, carbon cold-rolled steel offers significant advantages over zinc alloy in terms of cost-effectiveness, aesthetics, strength, and durability. Here's why:

• Cost and Price Stability: Cold-rolled steel boasts a substantial cost advantage, with raw material prices roughly one-fourth that of zinc alloy. Additionally, steel prices tend to be more stable, ensuring predictable budgeting and sourcing.
• Superior Appearance and Fit: Cold-rolled steel components are typically manufactured through stamping and polishing processes, resulting in exceptionally smooth and flat surfaces. In contrast, zinc alloy fittings are often die-cast, which can lead to surface inconsistencies, lower flatness, and reduced contact area with mating furniture panels.
• Enhanced Strength and Torque: Cold-rolled steel exhibits superior strength, with fittings capable of withstanding torque levels exceeding 12 Nm. Conversely, traditional zinc alloy fittings typically manage only around 8 Nm and are more susceptible to breakage and fracture due to their lower material strength.
• Long-Term Durability and Corrosion Resistance: The application of a corrosion-resistant electroplated coating on cold-rolled steel fittings ensures long-term protection against oxidation and rust. Zinc alloy, lacking this protective layer, is prone to oxidation over time, ultimately leading to weakening and potential failure.
