Steel Tube Frame Office Chair

The steel tube frame office chair is an office chair made with steel tubes as the main supporting structure, featuring sturdiness, simplicity, lightness, and elegance.

Structure and Production

When producing a steel tube frame office chair, workers first use machines to bend the steel tubes into the bottom frame of the chair. Then, they weld the seat cushion part to the frame. After that, springs are fixed to increase softness and reinforced with steel bars. When making the backrest, the curvature is designed according to the comfortable sitting posture for long periods. The seat cover is made of leather. Workers lay the leather flat on the workbench, use a template to cut it into the appropriate shape, and then cut a piece of sponge of the same size. The sponge, which is placed between the frame and the leather cover, determines the softness of the seat. Then, the sponge and the leather cover are sewn together and installed on the seat frame. Before installing the sponge on the backrest, a layer of particleboard is added to increase stability. A cover is added to the base for stability, and there are screw holes on the cover for connecting the supporting structure. The supporting frame includes a hydraulic device for adjusting the height, a 360-degree rotating bearing, and movable wheels. Finally, the headrest and armrests are assembled.

Performance Advantages

The steel tube frame has a high strength-to-weight ratio, allowing it to control the overall weight while ensuring structural stability. The cross-sectional shape and wall thickness of the steel tubes determine the rigidity of the frame. The welding process solidifies each connection point into a whole, preventing looseness or abnormal noises during long-term use. Some steel tube frame office chairs use electrostatic spraying for surface treatment. Through high-voltage electrostatics, powder coatings are evenly adsorbed onto the surface of the steel tubes and then cured at high temperatures to form a dense coating. This process results in a coating with strong adhesion and uniform thickness, effectively isolating air and moisture, delaying metal oxidation, and being more environmentally friendly than solvent-based coatings.

Market Prices

The prices of steel frame office chairs on the market vary. Simple and modern integrated steel frame office chairs cost about 50 yuan. Ergonomic chairs such as home computer chairs with comfortable long-sitting backrests range in price from 48.36 to 94.64 yuan. There are also other types of steel frame office chairs with different prices.
