High Tensile Force PC Strand For Underground Projects
Mining steel strand is a high-strength prestressed material used for reinforcement of surrounding rock of coal mine roadway.
Mining steel strand has reliable anchoring performance, sufficient bearing capacity and good applicability.
The advantages and safety of anchor cable support have been fully demonstrated.
If there are anti-corrosion requirements for mining anchor cables, corresponding anti-corrosion measures can be taken according to the environmental conditions.

→ wait the wire rod after aging period
→ wire rod surface treatment
→ 9 times drawing
→ half -finished product , inspection , configure right coils ready for stranding
→ stranding
→ tension and heat treatment
→ big reel of finished products
→ coil as per specific weight range, both ends of coil be tested
→ coil stay in normal condition for at least 24 hours
→ weighing
→ packing
→ label.
Some common attentions in using of our 19wires mining steel strand.
- Mining anchor cables should be lightly loaded and unloaded during transportation, and should not be thrown at will, so as to ensure that the anchor cable products are not damaged or contaminated with oil.
- The anchor cable should be used as soon as possible after it is made. If it needs to be stored for a long time, it should be placed in a dry and clean place to avoid rust and oil pollution.
