DJB800 metal roof beam, also known as metal roof beam, is a hinged roof beam, which can be used in conjunction with various hydraulic props. The strength of the roof beam, the roof beam can be because of this cantilever support surface, the coal transportation road is above the wall in front of the roof, and there is a large support space between the wall and the coal pillar.

It can be combined with various types of single metal pillars to form a metal bracket, a high-strength roof beam for the support of coal mines in horizontal and gently inclined working faces.

The roof above the conveyor road makes a large mechanical support space between the coal wall and the pillar.

Characteristics of metal roof

Durability: The metal durability of metal roof depends on the type. Compared with other materials (such as wood, plastic or glass metal), metal roof also has various advantages, such as durability, which is easy to stand out and the most durable.

Practicability: The metal roof is designed to withstand strong wind, debris (leaves, branches, etc.), rain, snow, hail, mold, mold, rodents and other animals.

Environmental protection: If the roof is installed correctly, minimum maintenance is required. Most metals are easy to recycle because they can be used in future products.

The roof beam is a support beam used for the coal mining face, located under the roof above the single hydraulic prop, and transmits the pressure of the roof. It is the top beam used for supporting the top plate of coal mining face. According to the connection method, the roof beam can be divided into two types: hinged roof beam and non-hinged roof beam.

According to the cross-sectional shape of the top beam, the top beam can be divided into four types: A-type, B-type, C-type and D-type top beam. The roof beam can be combined with various types of single pillars to form a bracket, which is a high-strength roof beam for the support of the coal mine in the horizontal and gently inclined mining face. 

The top plate above the conveyor lane makes a larger support space between the coal wall and the pillar.

Overview of metal roof market

The rapid development of urbanization and construction industry is the main factor for the continuous growth of the metal roof market. The progress of building technology and the increase of material types are driving the demand for metal roofs in buildings. In addition, the change of people's lifestyle and the growth of disposable income have led to the renovation of buildings, which has promoted the growth of the metal roof market.

In addition, the growing demand for green building materials and materials with low life cycle costs, coupled with the growth of the construction industry and the government's initiatives on green building materials, are the main factors driving the growth of the metal roof market. In addition, the adoption of solar panels and energy regulations is affecting the metal roof market. Metal roofs can significantly save electricity, so the increase in the use of metal roofs in commercial and residential buildings is driving the growth of the metal roof market.
