Description

 

The concept of welded steel fabric/ mesh was first proposed in 1901, while the first major application was in 1908. In 1922, it was tested to be the sufficiently suitable material for roads of heavy traffic. By the close of World War II, it showed its strength because it requires less labor and time. It was seen as the perfect reinforcing material to help Europe re-build after the war. Before the turn of the century, it was accepted as a viable form of concrete reinforcement in building. It has also enjoyed great usage in other projects like airport runways and a number of architecturally groundbreaking buildings.

Advantages

 

Practicality

Welded steel mesh is a type of high strength and high efficiency concrete reinforcement materials. By using automated production lines, the high-strength cold-rolled or cold drawn longitudinal and transverse steel bars will be welded into steel mesh, replacing the traditional on site steel fixing, which represents a big leap towards industrialization. Welded steel mesh is suitable for steel frame structure and in reinforced concrete slabs, walls, road works, pavement, culvert etc.

 

Steel Consumption Savings

Welded steel mesh is processed from low carbon hot-rolled wire rod through cold-drawn or cold-rolled process. The tensile strength could achieve up to 550MPa or more, resulting to 30% steel savings. In addition, the wastage could be kept minimal due to factory-controlled automated production line.

 

Better Project Quality

Welded steel mesh is manufactured through automated production line with strict quality control. The quality requirements, such as wire specifications and mesh size can be effectively controlled. These help to prevent the defect and illegal steel reduction, which usually appear in the traditional steel fixing, thus improve the quality of construction.
