The skeleton of budget furniture - furniture TUBES

For furniture manufacturers or buyers, identifying the quality of furniture tubing is crucial:

Raw Materials:
Thickness Tolerance: National standards have allowable ranges, but inferior tubing will exceed these limits, even falling short of the nominal thickness. We have strict product inspection procedures to ensure that product quality and parameters match.

Material Guarantee: We ensure that it is Q195 from a reputable steel mill, and we absolutely do not use substandard steel or inferior recycled materials. We have our own factory, so we personally control the raw material procurement process.

Process and Dimensions:

Weld Quality: Should be flat and firm, without incomplete welds or leaks. Can be checked through a flattening test.

Dimensional Accuracy: Outer diameter, diagonal, and wall thickness uniformity. This directly affects interchangeability during assembly and the aesthetics of the finished product.

Roundness/Right Angles: Square tubes should be "square," and round tubes should be "round."

Surface Treatment:

Coating Adhesion: Tested using the cross-cut method; the coating should not peel off in large patches.

Coating Thickness and Uniformity: Average thickness should be ≥60μm, with good coverage at edges and corners.

Corrosion Resistance: Salt spray test hours are a key indicator (e.g., ordinary spraying requires 240 hours without red rust).

Summary: The furniture tubing industry is a cornerstone industry supporting metal furniture manufacturing in China and globally. It is highly mature and efficient, a typical manifestation of the advantages of "Made in China."

The model of simply selling raw material tubing is no longer sustainable. The way forward for businesses lies in "extending services upstream and strictly controlling quality internally." By providing in-depth processing solutions and establishing a reliable reputation for quality, they can break through the homogeneous competition and serve brand clients who demand high quality.

For users, when choosing a furniture pipe supplier, they cannot only look at the unit price. They must comprehensively examine the supplier's material sourcing, process control, testing capabilities, and in-depth processing support to ensure the structural safety and durability of the final furniture products.
