The economic comparison between the anti glare board and the 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 according to the technical specification of the Ministry of Communications)

A、防眩板由600cm长一段组成

A and anti glare board are made up of 600cm

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 piece of shading board is connected by the upper and lower 2 inches of galvanized pipe according to the 50cm spacing.

C、每片遮光板长79cm，宽15cm，厚0.4cm

C, each piece of shading board is long 79cm, wide 15cm, thick 0.4cm

D、Ф2英寸镀锌管28元/米

D, 2 inch galvanized pipe 28 yuan / M

E、4米/延米薄钢板4.2元/ kg，热镀锌3.7元/kg

E, 4 m / M 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）

The overall processing cost of F, anti glare board is 2.8 yuan /kg (including machining, welding and other materials manual).

（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

(600/50+1) x (79 x 15 x 0.4 x 0.00785) x (4.2+3.7+2.8) + (28 * 6 * 2) =13 * 3.72 * 10.7+336=853 yuan /6 M

(二)防眩网是扩张金属网

(two) the anti glare net is an expanded metal net

A、 （热浸锌表面处理可保15-20年不锈蚀）

A, (hot-dip galvanized surface treatment can be guaranteed for 15-20 years without rust).

B、 规格网孔：SWM30mm×LWM75mm，厚度3mm,切口宽8mm网片宽LWM75cm (迁就完整网孔）防眩网每段长2m或2.5m（视设计要求）

B, standard meshes: SWM30mm * LWM75mm, thickness 3mm, width of cut 8mm wide mesh LWM75cm (to accommodate intact meshes) anti glare net each segment of long 2m or 2.5m (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, Guangzhou port delivery price)

以USD1： 8.3汇率计算（0.75×2）×3×19.96×8.3= 746元/6m

At USD1:8.3 exchange rate (0.75 x 2) x 3 x 19.96 x 8.3= 746 yuan /6m

按6m长一段对比计算防眩网是比较经济的，且外形美观，风阻少，同时能满足80 ~150遮光角的技术要求，横向透视效果佳，对驾驶员心理影响小。热镀锌质量可保证15-20年不锈蚀，能延长使用寿命，减少维护费用。且安装便利，不易损坏，接触面小，不易沾尘能长久保持整洁。总之防眩网能充分满足防眩光的各种技术要求，且经济合用，得到世界各国广泛使用，是一种比较好的防眩材料。

According to the 6m length comparison, the anti glare net is more economical, with beautiful appearance, less wind resistance, and can meet the technical requirements of 80 ~150 shading angle at the same time, the lateral perspective effect is good, and the driver's psychological influence is small. The quality of hot-dip galvanizing can ensure no rust for 15-20 years, prolong the service life and reduce maintenance costs. The utility model has the advantages of convenient installation, uneasy damage, small contact surface, and being difficult to dust and keep clean for a long time. In short, the anti glare net can fully meet all kinds of technical requirements of anti glare, and it is widely used in many countries all over the world. It is a good anti glare material.
