China's building curtain wall, door and window industry continues to develop and mature. The total industry output value is expected to rise from 20 billion USD in 2010 to 85 billion USD in 2020. The competition among the same industry in China is becoming increasingly fierce. Objectively, it is necessary for China's curtain wall, door and window industry to continuously expand outward. Therefore, it is necessary to conduct in-depth research and analysis on the national market at different levels of economic development. The countries along the “Belt and Road” need to pay more attention, because the infrastructure development of these countries along the route plays a role in enhancing the strength of various chain enterprises in China's building exterior wall industry. Important traction. According to the latest data of the 126th Canton Fair, there were 186,015 buyers from 214 countries and regions; the proportion of buyers attending each session of the countries along the route is more than 45%, which is on the rise; the International Import Expo has accumulated more than 8000 times along the route The participation of enterprises from countries and regions is the largest group of exhibitors. At the 126th Canton Fair, the export turnover of countries along the “Belt and Road” was US$11.056 billion, an increase of 14.81% and accounting for 37.75% of the total turnover.

The upstream and downstream raw materials and finished products of China's curtain wall, door and window industry still have strong competitiveness. Due to China's complete exterior wall industry chain, multiple levels of brand grades, wide options, and a wide range of cost prices, foreign merchants have a strong interest in Chinese material products. In the process of overseas design and technical services, we have experienced some on-site technical service cases of projects in different levels of countries and regions, and summarized some experience in cross-border cooperation with curtain walls, doors and windows. In terms of cooperation targets, these market countries are mainly divided into three categories: underdeveloped countries, developing countries, and developed countries. Although these countries have different stages of economic development, their cooperation with China is highly complementary.

1. The Global Marketing of Countries with Slower Industrialization

Among the many countries with slower industrialization in China's neighboring countries, Bangladesh is a very typical representative. Generally speaking, Bangladesh has a small land area, dense population, and sufficient labor force (according to statistics, the total population of Bangladesh is about 160 million people in 2015). Although it does not border China, it has a strong demand for China's bulk industrial products. In recent years, China has been Bangladesh's largest source of imports. In 2018, imports reached 11.95 billion, a year-on-year increase of 17%.

Dhaka is the capital of Bangladesh and has two main districts. Located in the most prosperous Gulshan street, the northern area close to the airport is more modern and the streets are more tidy; the central area is the bustling CBD with dense high-rise buildings. The land system in Bangladesh is privately owned, and land resources are fragmented. Perhaps because Dhaka does not have a similar system for bidding and auctioning land, it is impossible to easily merge large plots of land to build large-scale communities or commercial real estate. But the advantage is that the whole city is more intimate and full of human touch. There are many curtain wall projects in Dhaka, but the individual buildings are not large, and the facades of individual projects are novel. The guess is that the area of the plot is small and the streets of the city are narrow. The architect must increase the attractiveness of the façade through various forms of local modeling.

1.1 Local external wall system

The local building curtain wall system is mainly framed glass curtain wall, aluminum panel system, perforated aluminum panel system, concrete panel and full glass or spot glass system. Almost all commercial office buildings use point glass or full glass systems on the first floor or 2~3 floors. Quite a lot of curtain walls do not consider fire protection requirements, unless some high-end owners explicitly require consideration of fire protection and sound insulation requirements. For example, the owner responsible for the design of a project plan is Mobil. During the meeting and communication, they constantly complained about the lack of sound insulation of the upper and lower floors and the left and right rooms.

1.2 Features of the local curtain wall

The curtain wall design concept of local buildings lags behind, and the types of curtain wall systems are relatively simple. For example, the building does not consider fire protection between curtain walls. However, it is worth noting that the hidden fire hazards of most local buildings are achieved by isolating the upper and lower floors through floor panels (locally called Floor to Floor).

Hidden frame glass systems are widely used. The overall texture of the curtain wall is relatively rough, which is mainly reflected in the following aspects: if the nail heads are exposed seriously and the steel structure (the term "steel structure" is provided by Google) is poor; if the expanded carbon steel bolts at the bottom of the railing are exposed, it is easy to rust ; Such as uneven installation of the keel.

1.3 The cooperation model between Bangladesh and China 

1.3.1 Technical level.

1.3.2 Product level

Most Bangladeshi customers fly directly to China for on-site inspections and select products with high cost performance. Except for the material brands of western countries designated by Party A, Bangladesh's exterior wall construction units generally import bulk decorative materials from China and India. According to feedback from the person in charge of the construction unit, India’s material procurement cycle is long and the delivery date is uncertain, but because India borders Bangladesh, the space is close, and the price is more suitable, India can be one of their sources of imports. In contrast, the delivery cycle of materials and products in China is guaranteed. In the common people's impression, due to language barriers and traffic inconveniences, the "comrador" system will prevail. But now Bangladeshi customers will frequently fly to China to shop around, compare the quality and price of exterior wall materials in the Pearl River Delta, Yangtze River Delta and the Beijing-Tianjin-Tangshan Economic Zone, and finally purchase the best cost-effective products.

After introducing Chinese curtain wall technology and material products, and drawing lessons from domestic construction management measures, the local construction unit gradually improved the construction quality of the project. The local construction unit in Dhaka, Bangladesh will try various business strategies, such as hiring experienced installation workers from China with favorable treatment to go to Dhaka for on-site technical guidance. This strategy has two main purposes: The first is customer marketing. Party A will further recognize the local construction unit that is equipped with Chinese technicians on the site. At least on the surface, the construction unit should have better technical service capabilities; secondly, improve the technical management experience of the installation team of the construction unit. Of course, in this coordination process, due to differences in language, cultural background, and construction habits, there are still various contradictions and collisions between the two parties.

Along the “Belt and Road” in China, many of them are developing countries, and their exterior wall industry is entering a stage of rapid development. Due to the small size of the economy, there is no supporting industrial chain. Except for some hardware (the term "hardware" is provided by the industry encyclopedia), the auxiliary materials can be made domestically, and the other main materials are imported. Due to the land system of these countries, the project volume is not large, resulting in a small purchase of materials. They may only purchase dozens of sets of hardware, a few tons of aluminum profiles, and hundreds or thousands of square meters of glass at a time. This places higher requirements on the flexible production capacity of some domestic manufacturers. However, in order to realize flexible manufacturing of product production, companies need to improve product process and automation technology, and this challenge is often not purely based on technology, there are many other levels, such as industrial chain matching, enterprise management upgrade, Adjustment of enterprise employment structure and so on. Flexible design often greatly reduces the stability of the product, especially when the product is changed, a production line (the term "production line" is provided by the industry encyclopedia) should be changed from producing one product to producing another product. , This involves a lot of tooling and fixture adjustments, changes in processing procedures and parameters, selection of tool technology, etc. These things require a lot of labor costs and time costs to digest.

At this stage, although the procurement volume of individual project materials in such countries is small, the national grand strategy actually provides a large and growing overseas sales market for domestic small and medium-sized enterprises in China. Compared with China's exterior wall industry, which has developed through fierce competition for 20 to 30 years, the technical requirements of the exterior wall industry in these countries are generally looser. The exterior wall SMEs that have been baptized by brutal competition in the domestic market can position these markets as the first to go overseas. Stand, accumulate overseas operation experience through small projects, train the team, improve management, and strengthen yourself.
