Aluminum Doors and Windows Curtain Wall Profile Purchase Selection New Direction

【CNC】 In the bidding process of doors, windows, and curtain walls, the selection of profiles, developer procurement managers and designers often only consider the specific requirements of the profile structure, and under the premise of meeting the specifications of the building, Taking into account the economics of the profile structure, it is economically necessary to decide which profile structure to use in the final analysis. From the design point of view, too much emphasis on the economy of the profile of the door and window structure, must be at the expense of the performance of the entire window as the premise.

In the bidding process of doors, windows and curtain walls, the choice of aluminum profiles has gradually been valued by the owners. The reasons for backtracking are as follows: First, consumers have increased their quality requirements for purchased or used properties. The development of the real estate industry has also gradually increased consumers' right to speak, and they have the right to choose the quality of the products they have purchased; on the other hand, The requirements for energy efficiency in buildings have gradually increased, which has caused the passive improvement of the quality of doors and windows, and the entry of large international curtain wall and curtain wall enterprises into the Chinese market has enabled many domestic profile companies to innovate on their own initiative and adapt to market demands and industry development.

Real estate procurement selection influences industry development According to agency survey statistics, the overall supply of architectural aluminum profiles in the country from 2012 to 2015 exceeds demand. Even under this background, the production base of aluminum profiles is transformed from the original larger town of Nanhai aluminum materials into Guangdong and Jiangsu. Aluminium profiles in Jiangxi, Jiangxi, Shandong, and other regions are in the same situation. Of course, there are differences in product quality because of production technology and supporting industries.

Due to the homogeneity of single aluminum profiles, the price competition directly caused by the increasingly fierce competition, the external world is also facing the eyes of foreign systems and doors, the cake is shrinking, and the more eaters, the domestic many profiles and even doors and windows companies are facing the reform and transformation The situation of survival.

As the upstream industry of the architectural aluminum profile industry, the selection of aluminum profiles by real estate developers directly affects the development direction of the aluminum profile industry. When the development of the real estate market becomes more rational, the increase in the overall volume slows down, and the quality has improved. This is also the time when aluminum extrusion companies really want to develop products suitable for consumers of the times. The aluminum profile industry is a parasite in the real estate industry and can help designers create colorful mottled products. Only when the two sides care about each other can the green ecological balance be maintained.

Aluminum product R & D and innovation direction In recent years, domestic aluminum product company R & D and innovation mainly has two directions: First, the profile production process innovation. There are two main ideas in production process innovation:

The first is the safety and environmental protection of the production process, such as the non-chromatization of aluminium profiles before spraying, the use of alkaline sand in fluorocarbon fluorocarbon paints and electrophoretic oxidation profiles in place of acid sands, etc. These processes are based on years of production and processing of aluminium profiles. Under the premise of technology, in order to respond to environmental protection policies, it is beneficial to improve production efficiency, reduce production costs, and achieve innovative scientific research results. It is understood that these new production processes have already transformed some of the profiled enterprises with high environmental protection requirements in Guangzhou into mature productive forces and are being used in large quantities in domestic large-scale construction projects;

The second is the innovation of profile processing methods: In order to meet the increasingly rich spiritual and material needs of consumers, the color of aluminum building profiles has been transformed from the silver and green colors of the 1990s to the current custom colors, that is, designers can build buildings based on Face color and interior decoration styles are required to provide suppliers with swatches of any desired color, and suppliers can provide the same colored profiles with the help of downstream paint suppliers.

Comprehensive summary, the current surface treatment of the main building profiles are divided into seven categories: materials (no surface treatment), oxidation, electrophoresis, powder coating, fluorocarbon baking paint, wood grain, composite profiles. These major categories of surface treatment are more basic and more traditional surface treatment methods. In recent years, apart from materials, almost every type of surface treatment has its own innovation.

Under the premise of guaranteeing the weatherability of surface treatment, the well-known ceramic china swimming pool developed on the basis of traditional electrophoresis technology, such as a Japanese brand, has higher film thickness than conventional electrophoresis, and the film quality is higher than that of conventional electrophoretic paint film. , The color is more full and the weather resistance is good.

In the field of powder coating, Italy's wood grain spraying has also been introduced. Compared with the traditional wood grain printing, the weathering resistance is better and the three-dimensional effect is stronger. The surface of the fluorocarbon is also gradually recovered from the traditional baking paint process, and the chemical gas is not released. Weather resistant fluorocarbon powder coating process changes. These new processes are the result of technological innovations and are lower in cost than traditional processes.

Composite profiles are also contending with a variety of materials with good insulation properties and good decorative materials and aluminum profiles, mainly to meet the Chinese traditional culture in respect of wooden doors and windows.

The more common are solid wood and aluminum composite profiles, which are divided into two types, aluminum package wood and wood package aluminum. The two main differences are in the main stress location. The aluminum cladding is composited on the side of the traditional aluminum alloy profile through plastic parts or other methods. The upper layer of wood or composite wood materials, metal slot and aluminum alloy slot; and aluminum package wood is closer to the pure solid wood doors and windows, the main force and metal slot are located on the wooden structure.

The aluminum-clad wood profiles usually seen are more expensive than wood-clad aluminum profiles. In addition, the wood of aluminum-clad wood profiles is mostly solid wood, and the wood of wooden-clad aluminum profiles includes both solid wood and various kinds of composite wood.

Another innovative direction in the design and development of profile structures is the design development of profile structures. The design and development of the section structure is based on hardware accessories. The X-axis is economical and practical to meet different airtight and watertight physical properties such as “Y-axis” and open according to different doors and windows. , curtain wall structure to comprehensively consider the design process.

The research and development of profile structure design is an important aspect of the daily design work of profile companies. It is also mainly to respond to market competition, to meet the requirements of developers and subcontract units for windows and doors, and to continuously improve and perfect the existing product lines in order to achieve higher levels of sex. standard.

After nearly ten years of rapid development of the real estate market, the company's doors and windows series have evolved from the ordinary 50 series flat open, 90 push and pull, single Ming concealed curtain wall development to now all kinds of broken bridge non-broken bridge doors and windows, all kinds of Unitary curtain wall. Each molding company mold at least 100,000 sets, as many as millions. The continuous improvement of the series has improved the quality of doors and windows, but also caused a huge waste of resources for the profile companies due to the lack of systematic management.

Profile selection can not sacrifice the performance of the entire window. Therefore, in the bidding process of the window and curtain wall project, the selection of profiles, developer procurement managers and designers often only consider the specific requirements of the profile structure, in order to meet the requirements of the building specifications Next, the economics of the profile structure are taken into consideration, and the economics are used to decide which profile structure to use in the final analysis.

From the design point of view, too much emphasis on the economy of the profile of the door and window structure, must be at the expense of the performance of the entire window as the premise. Therefore, in the series of selection above, developers should choose a set of relatively mature system structure as the basis for bidding.

In the tendering and bidding process of doors, windows and curtain walls, the selection of aluminum profiles mainly involves the above two aspects. The diversity of profile types provides designers and procurement managers with more choices. It is recommended to encourage the selection of mature and stable new surface treatments. Suppliers of such surface treatment profiles should be intensively visited to assess and select enterprises with mature production experience and have Independent production technology research and development and inspection and testing capabilities of enterprises, establish long-term strategic cooperation. Firstly, it can provide the feasibility of embodying different architectural features. For aluminum profile companies, it is also an encouragement for innovation, which helps to curb low-price competition and contributes to the healthy development of the industry.

In the later stage of cooperation, in order to ensure the progress of the project and delivery time of the profile, developers, subcontractors, and profile suppliers should have clear and specific progress nodes, avoiding the formation of a large backlog of inventory of profiles and finished products for subcontractors. Can effectively guarantee the delivery period of the profile.

The doors and windows are the eyes of the building body, and its quality is directly related to the facade effect of the entire project and the owner's living experience. The aluminum profile plays a decisive role in it. When the architect has a high standard for the aluminum profiles, the aluminum industry will be rewarded with different quality to decorate the building with brighter eyes. Improve the quality of doors and windows.
