  • Technical Parameters:

    1. The center distance between two seats is 530mm.

    ★2. The legs are made of die-cast aluminum alloy, molded by die casting, with an upper arc design for good safety. The leg height is 860mm, the column width is 200mm, thickness 12mm; the base length is 265mm, width 60mm. The outer side of the aluminum leg is covered with dark gray (upper) and light gray (lower) ABS plastic decorative panels, molded, sturdy and easy to disassemble.

    ★3. The seat rebound structure is composed of aluminum alloy components, forming an elastic rebound structure with built-in silencing device, rebound without noise.

    ★4. The back panel backing board width is 260mm, made of 1.2mm thick "Ansteel" steel mesh processed. "Ansteel" The steel plate thickness is 1.2mm, mesh diameter 3mm.

    5. The seat fixing crossbar is 40*80*1.8mm "Shougang" rectangular steel tube.

    ★6. The three-dimensional curved seat board and back panel conform to ergonomic principles. The substrate plywood is made of 1.5mm birch veneer cross-bonded horizontally and vertically, coated with environmentally friendly "Shengji Yijia" formaldehyde-free glue, molded once by high-frequency press, with 1mm thick beech veneer surface on both sides. Finished dimensions: The seat board is 440*380*1 mm, the back panel is 450*355*1 3 mm. 3 The surface is coated with "Bauhinia" water-based paint, five-base three-coat process, uniform color, smooth and flat surface, yellowing resistant. The seat board and back panel are connected integrally with the rebound mechanism and support parts through hardware, sturdy and durable, and the hardware is flush with the seat and back panel after assembly. Formaldehyde emission < mg/m³ 0.01 7. The plywood meets the requirements of GB/T 9846-2015, GB 18580-2017, GB/T 39600-2021 standards, with bonding strength of 1.4MPa, 。

    grain static bending strength MPa, cross grain static bending strength 66.6 MPa, grain modulus of elasticity 60.8 MPa, cross grain modulus of elasticity 8790 MPa, 7930 moisture content %, impregnation peel length ≤25mm, 9 formaldehyde emission < length deviation, width deviation, perpendicularity deviation, edge straightness deviation, flatness deviation, thickness deviation, and appearance quality all meet standard requirements. 0.023 7. The plywood meets the requirements of GB/T 9846-2015, GB 18580-2017, GB/T 39600-2021 standards, with bonding strength of 1.4MPa, Water-based primer meets

    GB18581-2020, HJ2537-2014 standards, VOC content , formaldehyde content < 3.12g/L 5mg/kg, total lead content <0.02mg/kg, cadmium <0.02mg/kg, chromium <0.02mg/kg, mercury <0.002mg/kg, total content of glycol ethers and ether esters < mg/kg, total content of benzene series < 13.5 mg/kg, halogenated hydrocarbons < 11.2 Water-based topcoat meets 37.4mg/kg.

    8. Surface treatment VOC content , formaldehyde content < 3.05g/L 5mg/kg, total lead content <0.02mg/kg, cadmium <0.02mg/kg, chromium <0.02mg/kg, mercury <0.002mg/kg, total content of glycol ethers and ether esters < mg/kg, total content of benzene series < 13.5 mg/kg, halogenated hydrocarbons < 11.2 Water-based topcoat meets 37.4mg/kg.

    Wood parts: thick paint film, good hand feel, yellowing resistant, odorless, good leveling, no wrinkling, no bumps, no bubbles, etc.

    Metal parts: all are shot blasted with steel shots for physical degreasing and rust removal, then electrostatically sprayed with light gray matte finish on an automatic spraying line. The finished product has uniform color, strong adhesion, and strong impact resistance.

    9. After assembly, the row chair is firm and does not shake; when supporting the table with both hands, the table surface does not bend downward. The whole chair is odorless, and the seat and backrest durability withstands 100,000 cycles without damage.

    9.排椅组装完成后，牢固不晃动，双手支撑台面时台面无向下弯曲形变。整椅无异味，座面、椅背耐久性10万次无损。
