What is a Concrete Nail (Steel Nail for Concrete)?
A concrete nai is a high-strength steel fastener engineered specifically for penetrating and securing into tough substrates like reinforced concrete, brick, block, and masonry. Unlike general-purpose wire nails or 10d nails, concrete nails adopt specific alloys (low-carbon or medium-carbon steel, sometimes with additional heat-treatments) to maximize:
- Hardness (HRC 50–56): Ensures penetration without bending or breakage
- Tensile Strength (≥ 700 MPa): Withstands high loads and pullout forces
- Corrosion Resistance: Options include galvanized, black concrete nail (oxidized), and epoxy-coated finishes

FAQ: Concrete Nail Steel Nails—Technical Questions
1. What material grade is recommended for concrete nai production?
High-carbon or medium-carbon steel such as Q195, Q235, or 45# steel is ideal. It provides the necessary hardness (50–56 HRC) and tensile strength to penetrate concrete without deformation or splitting. Lanye uses exclusively certified wire meeting ISO/EN standards.
2. Which surface finishing is best for exterior/concrete wall applications?
Galvanized or black oxide concrete steel nails are recommended for outdoor or humid interior jobs. Zinc galvanized finish delivers up to 148 hours of salt spray resistance; black oxide gives aesthetic value and baseline corrosion protection.
3. How do you ensure the dimensional accuracy of concrete nail sizes (e.g., 3 inch, 1 1/2 inch, etc.)?
Strict inline measurement systems post-wire drawing and after cutting, with ISO 2768-mK tolerance levels applied. Regular random sampling with digital gauge and spectrometer verifies compliance every batch.
4. What are the main standards and certifications for these nails?
Concrete nails for professional construction must comply with ISO 898-1, ASTM F1667, JIS B1162, ANSI A153, and project-specific specs such as EN 14592 or local GB/T 1348 for quality, mechanical properties, and finishing.
5. Can concrete nai be used for steel-to-concrete fixing?
Yes. Specialized steel nails for concrete, typically 3.0–5.0mm diameter, can fasten thin steel sheet or track to concrete for tasks such as HVAC, curtain wall, and frame anchor installation. Always drill pilot holes if using ultra-high density substrates.
6. Is it possible to order custom small concrete nails or concrete nai with hooks?
Absolutely. We manufacture sizes as small as 1 inch, and hook-shaped or washer-head options, upon submission of drawings or specs. Contact our engineering team for development and prototyping.
7. What is the usual delivery and warranty period for bulk concrete nail orders?
Standard orders ship in 7–18 days (depending on size & finish), with a 12-month quality warranty covering rust, failure, or dimension defect, backed by full technical documentation and after-sales support.
Delivery Lead Times, Quality Guarantee & Support
- Lead Times: Standard bulk: 7–18 days, urgent batch: 3–6 days, OEM/ODM: 18–25 days
- Warranty: 12-month no-fault warranty for material, coating, or dimension defects—includes free replacement/shipping
