Auditorium chair

1) Handrail column foot: It adopts 1.5mm thick high-quality hot-rolled steel plate, hydraulic pressure welding, the surface adopts advanced degreasing and rust phosphating treatment, electrostatic spraying by high-quality epoxy polyester powder coating, high temperature plasticizing treatment, and appearance is smooth. No rust, corrosion, epoxy powder coating in line with GB/T18593-2010 national standards.

2) The hexagonal solid shaft is used for lifting and lowering in the column foot, and the hexagonal guide sleeve is used to form a lifting and lowering pulley mechanism. When lifting, the seat can be easily moved. When stowed, it can be smoothly landed, convenient and practical, and will not scratch the ground when moving. In order to ensure the appearance, there should be no artificial sanding on the lifting foot and tail. The plastic foot cover and metal form a one-piece appearance.

3) Seat soft bag: The seat and back are made of built-in steel frame and polyurethane cold-solid foaming. Made of imported raw materials, the density is high, the seat feels comfortable, the resilience is good, and the sedentary does not collapse and does not deform. Flame retardant materials can be added to achieve a flame retardant effect.

4) Back length is 510mm, width is 460mm, thickness is 60mm, and back density is 45~50kg/m3. The seat is 190mm long, 460mm wide and 70mm thick. The seat density is 50~55kg/m3. The shaped cotton has good elasticity, no deformation, is not easy to aging, and has strong anti-absorption ability, and conforms to the GSP1176 standard.

5) Handrail: 300mm long, 50mm wide and 20mm thick, made of oak. Dewatering, drying and buffering treatment, it can effectively resist abrasion, stain and fading after environmentally friendly paint. Implementation of the GB18581-2009 standard.

6) Fabric: The fabric is made of high-quality hemp fabric, which is treated with three anti-static, anti-static and ball-free. The appearance is elegant and generous, with high abrasion resistance and comfortable sitting. Flame retardant materials can be added to achieve a flame retardant effect.

7) WordPad: It is supported by steel frame in the backrest, and the strap is twitched. The writing board is made of 15mm medium-fiber veneer. The release of free formaldehyde is less than 0.9mg/L, which is in line with national environmental protection standards.

8) Seat return mechanism: manual seat back and armrest surface linkage device, no noise when rotating, both sides are connected by high-quality steel mechanism, which can stably lower and lift two end points.

9) Welding: It adopts carbon dioxide protection welding, the welding joint is smooth and smooth, no undercut, no slag, and the welding is firm.

    Spray: Surface treatment: degreasing - washing - descaling - washing - neutralization - washing - conditioning - phosphating - washing - drying - electrostatic spraying - 200 ° C high temperature curing.
