Hot-dip Galvanizing Self-drilling Rock Bolts
Anti-corrosion Mechanism Immerse the derusted anchor bar and accessories in liquid zinc for a certain time, so that the atoms can penetrate and diffuse each other, thereby forming an iron-zinc alloy layer, which is dense, uniform, firmly bonded, bright and corrosion resistant. Zinc is an amphoteric metal. In thermodynamics, zinc has a stable area. Hot-dip galvanizing is an electrochemical anti-corrosion method, which hinder further corrosion through insoluble chemical substances produced by interaction between zinc and concrete solution. Product Standard Sinorock has formulated the standard for galvanized products coatings in accordance with ISO 1461 " Hot dip galvanized coatings on fabricated iron and steel articles Specifications and test methods". The coating thickness of main products is as follows: Featurs and Advantages Excellent anti-corrosion properties: As zinc is an active metal, after coating surface is damaged, it will protect the steel by battery effect. Long service life: Zinc layer is consumed very slowly in the atmosphere, so its service life far exceeds that of any other coatings. Full protection: As immersed into hot-dip galvanizing bath, products are fully protected and anti-corrosion effect is better. Lower price: In most cases, the hot-dip galvanizing cost is lower. Zinc coating is more durable than others, and does not require maintenance in the future. High processing efficiency: Hot-dip galvanizing bath is simple and efficiency is higher than other coatings. Not affect steel performance: Hot-dip galvanizing is carried out in an environment of more than 400 �¢??, and will not affect the performance and toughness of steel. Service Life Generally, the service life of hot-dip galvanized products is more than 50 years in most environments, and it will be different according to corrosion level of the environment. According to ISO 12944-2 "Paints and varnishes- Corrosion protection of steel structures by protective paint systems-Part 2: Environmental classification" (equivalent to GB/T 30790.2), The table below lists the reference rates for different atmospheric-corrosivity environment categories.
| HS Code | 7318.18 |
| Material | Carbon Steel Q235/Q355 with Hot-dip Zinc Coating (Zinc coating: 43-85 micrometers) |
| Bolt Diameter | 20mm - 40mm (common sizes: R25, R32, R38, T40) |
| Bolt Length | 1,000mm - 6,000mm (custom lengths available) |
| Thread Type | ISO 10213 / R / T series fully threaded or partially threaded |
| Zinc Coating Thickness | 43 - 85 micrometers per ISO 1461 / ASTM A123 |
| Grade/Tensile Strength | 550 - 700 MPa tensile strength |
| Standard | ISO 10213, GB/T 14329, ASTM A153 / A123 |
| Application | Underground mining, tunnel excavation, slope stabilization, geotechnical anchoring |
| Packaging | Bundled by length, plastic-capped ends, wooden pallets or steel drums for export |
Hot-dip galvanizing self-drilling rock bolts are engineered for rock reinforcement in mining, tunneling, and slope stabilization projects. These zinc-coated bolts feature self-drilling capability for efficient in-situ installation, with the hot-dip process providing superior corrosion resistance in harsh underground environments. Exported globally for geotechnical contracting and mining operations, they meet international standards for load-bearing anchor systems.
