现将防眩板与防眩网经济对比分析如下：
The economic comparison between anti-glare board and anti-glare net is as follows:
（一）防眩板（按交通部技术规范计算）
(1) Anti-glare board (calculated in accordance with the technical specifications of the Ministry of Communications)
A、防眩板由600cm长一段组成
A. The anti-glare board is made up of 600 cm long section.
B、各片遮光板由上下两根Ф2英寸镀锌管按50cm间距串接成
B. Each shade plate is connected by two 2 inch galvanized pipes from top to bottom in series at a distance of 50 cm.
C、每片遮光板长79cm，宽15cm，厚0.4cm
C. Each shade plate is 79 cm long, 15 cm wide and 0.4 cm thick.
D、Ф2英寸镀锌管28元/米
D, 2 inch galvanized tube 28 yuan/m
E、4米/延米薄钢板4.2元/ kg，热镀锌3.7元/kg
E, 4m/Yanmi steel sheet 4.2 yuan/kg, hot-dip galvanized 3.7 yuan/kg
F、防眩板整体加工费用2.8元/kg（包括机加工、焊接等材料人工）
F. Overall processing cost of anti-glare board is 2.8 yuan/kg (including manual processing, welding and other materials)
（600/50+1）×(79×15×0.4×0.00785）×（4.2+3.7+2.8）+（28×6×2）=13×3.72×10.7+336=853
(600/50+1)*79*15*0.4*0.00785)*4.2+3.7+2.8)+(28*6*2)=13*3.72*10.7+336=853
元/6米
Yuan/6m
(二)防眩网是扩张金属网
(2) Anti-glare mesh is expanded metal mesh
A、 （热浸锌表面处理可保15-20年不锈蚀）
A. (Hot-dipped zinc surface treatment can keep stainless for 15-20 years)
B、 规格网孔：SWM30mm×LWM75mm，厚度3mm,切口宽8mm网片宽LWM75cm (迁就完整网孔）
B. Specification mesh: SWM30mm * LWM75mm, thickness 3mm, notch width 8mm mesh width LWM75cm (accommodate complete mesh)
防眩网每段长2m或2.5m（视设计要求）
Each section of anti-glare net is 2 m or 2.5 m long (depending on design requirements)
C、 价格计算：USD19.96元/m（热浸，广州口岸交货价）
C. Price calculation: USD19.96 yuan/m (hot dip, delivery price at Guangzhou Port)
