Mining Steel Strand is a very common steel product, which is widely used in the construction of large-scale projects, such as bridges and houses. Although the structure of mining steel strand looks simple, it is very reliable in terms of firmness, and it also has very complicated technical processes. It is composed of strands of multiple steel wires. The surface of carbon steel can be added with galvanized layer, zinc aluminum alloy as required, such as layer, aluminum-clad layer, copper-plated layer, epoxy resin coating, etc.

According to relevant statistics, the demands of mining steel strands have gradually increased in recent years. There are many types of mining steel strands, from galvanized steel strands, unbonded steel strands to support steel strands, etc. Different types not only have different performances, but also their quality and price are different. In fact, in different production areas, the specifications of the required mining steel strands are also very different. So what are the common classifications of mining steel strands?

1. Classification by purpose: prestressed steel strands, (electrical) galvanized steel strands and stainless steel strands. Among them, prestressed steel strands are coated with anti-corrosive grease or paraffin wax and HDPE is called unbonded prestressed steel strand Wires, prestressed steel strands are also made of galvanized or galvanized aluminum alloy steel wire.

2. Classification by structure: Prestressed mining steel strands can be divided into 7 wires, 2 wires, 3 wires, and 19 wires according to the number of steel wires. The most commonly used is the 7 wire structure.

3. Classification by surface coating layer: It can be divided into (smooth) steel strand, galvanized steel strand, epoxy-coated steel strand, aluminum-clad steel strand, copper-plated steel strand, plastic-clad steel strand.
