Yes, we support full customization. We can produce various diameters and lengths as your mining engineering drawings, and provide hot-dip galvanized or black anti-rust surface treatment options.

Q:How to guarantee the tensile strength of your mine anchor bolts?

Our anchor bolts are made of high-strength steel bars with professional thread rolling process. Each batch will do tensile testing before delivery, comply with national mining safety standards, with 3 years quality warranty.
