Building intercom is a security system. In a multi-storey or high-rise building, a management system that allows visitors, residents and property management centers to communicate with each other, exchange information, and control access to the community's safe access routes is commonly referred to as a building intercom system.

Domestic development trend

1. The building intercom system is forming a relatively independent industrial sector

Although the development of the building intercom system in China is not long, its market prospects are promising. So far, manufacturers have soared to about 250 companies. Building intercom and television monitoring, anti-theft alarm, access control management, intelligent parking, etc. together constitute the security industry. Due to the progress of society, changes in human life patterns and thinking patterns, coupled with the economic development, the differentiation of social strata has intensified, and social security conditions are not optimistic, all of which have a great role in promoting the development of the security industry.

2. Increased sales volume, serious bidding industry, reduced profit margin

A company in the building intercom industry declined sharply at the beginning of the year. Although the bidding behavior can increase the overall sales volume, the profit reduction rate is also very large. Some manufacturers are aware that the bidding industry will bring serious consequences without any living space. Therefore, they are committed to improving product quality, increasing investment in after-sales services, and accelerating the progress of product development. The building intercom market segment gradually takes shape.

The building intercom system has been used in Europe and the United States, Hong Kong, and Taiwan for nearly 20 years. Since 1992, manufacturers of building intercom systems in foreign countries have successively opened up markets in China. So far, there have been nearly 10 foreign brands on the mainland, and domestic building intercom companies have developed rapidly. The market share of domestic building intercom systems is about 80%.

HDPE steel strip reinforced corrugated pipe Features

n High pressure bearing capacity, high impact resistance capacity: pipe is steel strip reinforced, high ring stiffness , good adaptability for any foundation conditions;

n Economy: lower cost than the specifications of other Plastic Pipe, light weight, save transportation and construction costs, easy management and maintenance; large diameter, high ring stiffness;

n Chemical resistance: will not be corroded by sewage, waste water and chemicals, will not be corroded by the substances in soil, it will not be damaged by plant roots;

n Anti-aging: the pipe is generally in black color, can withstand the direct sunlight in the stacking and construction process.

n Excellent wear resistance, Better than steel pipe.cast iron pipe, cement pipe;

n Superior drainage: small water flow resistant in the inner wall, Drain fast, Strong water passing ability. large fluid flow.

n The composite of each layer is carried out in the molten state of the plastic, which is completely different from the winding pipe (medium hole wall tube), so the composite fastness of each layer is very reliable;

n Pipe can be used hot melt welding, clamp type rigid connection, heat shrinkable belt connection and other connections, suitable for different piping system requirements, convenient and reliable.
