Office Chair Backrest Steel Plate

The office chair backrest steel plate is a key metal component used to support the backrest structure of office chairs. Typically made of cold-rolled steel plate or alloy steel, it features high strength, wear resistance, and deformation resistance, providing stable back support for users.

I. Main Product Types and Functions

1. Basic Support Steel Plates
   For example, the OJ-04 Multi-Size Steel Plate for Swivel Chairs from Foshan Oujun Metal Products Co., Ltd. is primarily used for the backrest frames of ordinary office chairs or lift chairs. Its design emphasizes structural stability, forming hollow or solid structures through stamping or welding processes, which reduces weight while ensuring load-bearing capacity. These steel plates are typically connected to chair seats, armrests, and other components via screws or clips, making them compatible with various chair types.

2. Reinforced Steel Plates
   The OJ-33 Sturdy Lift Office Chair Back Iron falls into this category, designed for gaming chairs or high-load usage scenarios. It has greater thickness and strength, with some products featuring thickened edges or reinforcing ribs to withstand frequent lifting or reclining actions, extending the chair's service life. Additionally, some reinforced steel plates undergo anti-rust treatments (such as spray coating or electroplating) to adapt to humid environments.

3. Multi-Functional Accessory Steel Plates
   For example, the OJ-02 Back Iron Linking Iron belongs to the hardware accessory category and is used to connect the chair back to the seat or headrest. Its design focuses on compatibility, typically featuring multiple mounting holes to accommodate different sizes of chair backs or additional accessories (such as adjustable headrests). These steel plates require high-precision machining to ensure no looseness or abnormal noise after installation.

II. Market Prices and Suppliers

1. Price Ranges

   • Basic steel plates (such as OJ-04) are priced lower, approximately ¥28.5 per piece, suitable for bulk purchases.
   • Reinforced steel plates (such as OJ-33) are more expensive due to upgraded materials and processes, approximately ¥285 per piece, mostly used in high-end chair models.
   • Hardware accessory steel plates (such as OJ-02) are the least expensive, approximately ¥10.45 per piece, but must be used in combination with other components.
   • Products from other suppliers (such as the iron backrests from Foshan Shengdeli Home Furnishings) range from ¥16.0 to ¥21.5, offering modern minimalist designs suitable for customization needs.

2. Supplier Services
   Most suppliers (such as Oujun and Shengdeli) provide material guarantees (such as compliance with national standards Q235 or Q345 steel) and shipping time commitments (such as shipping within 48 hours), supporting both wholesale and retail. Some merchants also offer custom processing services, adjusting steel plate sizes or shapes according to customer drawings.

III. Purchase Considerations

1. Material Verification: Prioritize products labeled with steel grades (such as Q235) to avoid using recycled materials or low-strength alloys.
2. Thickness and Weight: For reinforced steel plates, a thickness of ≥2mm is recommended, while ordinary types should be ≥1.5mm. Verification can be done through weighing or caliper measurement.
3. Compatibility: Ensure that the steel plate's hole positions match other chair components to avoid installation difficulties or structural instability.
4. Surface Treatment: Check for scratches, rust, or coating peeling. Anti-rust treatments can extend the service life.
