In steel furniture manufacturing, material selection directly determines product quality, longevity, and value. Faced with iron, ordinary steel, stainless steel, and cold-rolled steel, how to make the precise choice? This article cuts to the chase with a clear analysis.
Four Core Materials, Distinct in Nature
Iron (Cast Iron): High carbon content (>2%), hard yet brittle. Rarely suitable for modern formable furniture manufacturing.
Ordinary Steel (Carbon Steel): A balanced base material, but prone to rusting. Requires additional surface treatment and is primarily used for internal structures.
Stainless Steel: Contains ≥12.5% chromium, offering outstanding corrosion resistance. However, due to high cost and difficult processing, it is mainly used in specialized environments like kitchens, bathrooms, and medical settings.
Cold-Rolled Steel: Ordinary steel precision-rolled at room temperature. It combines high strength, precision, and superior surface finish, making it the preferred choice for high-end steel furniture frames.
Why do top-tier furniture brands favor cold-rolled steel?
Because it addresses three major industry pain points:
Stronger: The cold-rolling process significantly enhances steel strength and hardness, ensuring stable and secure load-bearing structures like bed frames and cabinet bodies with long-term resistance to deformation.
More refined: Its inherently smooth and flat surface provides a perfect “canvas” for processes like electrostatic powder coating, achieving a delicate and sophisticated final appearance.
Greater Efficiency: Its uniform composition and excellent stamping/bending properties enhance production precision and speed while reducing overall costs.
In Summary
Choosing cold-rolled steel isn't just selecting a material—it's embracing lean manufacturing and enduring quality. With its exceptional strength, refined surface, and superior workability, it stands as the unshakable foundation for crafting modern, high-quality steel furniture.
