Metal Support Legs for Beds

The Metal Support Legs for Beds serve as the primary load-bearing connection between furniture and the floor. Insufficient structural strength can lead to sinking, tilting, or long-term deformation of the furniture system.

Standard load capacity ranges from 100 to 150 kg per leg, depending on material thickness selection from 2.0 mm to 4.0 mm. For higher load requirements, a heavy-duty version is available with a capacity exceeding 200 kg per leg.

A project case involved outdoor furniture applications where each set weighed approximately 80 kg. The requirement was stable outdoor performance over five years without deformation. A heavy-duty carbon steel structure was used, combined with a cross reinforcement rib at the base. Under a test load of 250 kg, measured deformation remained within 0.2 mm.

Common material options include SPCC steel, selected for its balance of cost and strength, 6061 aluminum for reduced weight, and stainless steel for improved corrosion resistance. Maximum material thickness can be produced up to 6.0 mm, depending on structural requirements.

Bottom flatness is controlled within 0.15 mm, ensuring stable contact with the floor surface and preventing wobbling during use. Each production batch is checked for flatness consistency before packaging.

Electrostatic powder coating with a thickness of 80 μm is applied as the standard surface finish. Adhesion performance meets cross-cut Grade 0, indicating no peeling under standard testing conditions. For indoor applications, black zinc coating is also available, with color options customizable based on customer requirements.

Springback compensation is adjusted during bending based on material thickness and forming angle. Parts with angular deviation greater than 0.5° are removed from the production line to maintain consistency.

All processes, including welding, grinding, powder coating, and packaging, are completed in-house within a 1,200 m² workshop. No external outsourcing is used to maintain full control over production quality.

Quality control is implemented through a three-step inspection process: self-inspection, peer inspection, and final supervisor approval before packing. Sample production typically requires 3–5 days.

Any confirmed manufacturing defect within three months is covered with replacement and shipping support.
