FAQ

1、How should one select between 1×7 and 1×19 mine steel strands?

1×7 is used for shallow support in conventional roadways; 1×19 has higher load-bearing capacity and is suitable for the reinforcement of deep mines and high-risk roadways prone to rock bursts.

2、Can the length tolerance meet the construction requirements for mining anchor cables?

Precisely measured and cut, with length tolerances meeting mining standards, ready for direct processing.

3、Is it possible to provide mining-related inspection reports?

The product has obtained the Coal Safety Certificate. Each batch of the product is accompanied by a factory quality certificate and a mechanical performance test report, and supports inspection submission.

4、How long is the delivery cycle approximately?

Regular standard specifications are available for immediate delivery. Large-volume orders and customized products can be expedited in production. The delivery cycle is short, and shipment schedules can be flexibly matched according to project timelines to avoid delaying construction progress.

The steel strands are supported at the bottom with wooden cradles and fully wrapped with blue waterproof cloth, secured with high-strength steel straps, providing dustproof, moisture-proof, and rust-resistant protection; product information labels are affixed on the coil surface, making stacking and transportation less prone to unwinding, suitable for various land and sea transportation scenarios, comprehensively protecting the product.
