Our expansion anchor Bolt is crafted through multi-step metal processing technology to guarantee stable mechanical performance. The raw material adopts national standard Q235 carbon steel, with stable hardness and tensile strength to meet daily construction fixing demands. The production workflow includes raw material cutting, thread rolling, sleeve stamping, assembly forming and full yellow zinc electroplating surface treatment. We strictly avoid extra lacquer and wax coating on the surface to keep the bolt’s original mechanical friction performance during wall installation.
For quality control, every batch of expansion bolts undergoes random tensile load testing, thread inspection and plating thickness detection to eliminate defective products before packaging. Compared with cheap inferior anchor bolts in the market, our products feature thicker expansion sleeves and complete uniform zinc coating, which effectively avoid sleeve cracking and premature rust during long-term use on construction sites.
Customization flexibility is our core advantage for B-end buyers. We adjust bolt length, thread diameter and plating thickness according to customer engineering drawings. For brand importers, laser engraved logo on bolt nuts or sleeves is supported without extra mold cost for large bulk orders. All finished Bolt goods comply with GB and DIN international fastener standards, suitable for cross-border export to most global markets without standard certification barriers.
