Product Description

Refined Professional Application Overview of Concrete Nails

Cement steel nails, the epitome of robust fasteners, are meticulously engineered for substrates demanding high hardness such as concrete, brick walls, and stone. These nails undergo a rigorous cold heading forming and quenching-hardening process, bestowing them with unparalleled strength and impact resistance. Extensively utilized across construction, decoration, and industrial sectors, these nails boast a myriad of core features, technical parameters, and operational applications. Let's delve into the details:

------

1. Core Structure and Material Attributes of Cement Steel Nails

1. Material Composition and Heat Treatment Technique

Crafted from premium medium carbon steel (like C45) or alloy steel (such as 40Cr), featuring a carbon content of 0.42% -0.50%, these nails provide foundational strength.

• Advanced Heat Treatment Process:

• Comprehensive Quenching: The nails are heated to a precise 850-900 ºC, followed by rapid cooling, reaching a surface hardness of HRC52-58. This process achieves an impressive bending strength of at least 1200MPa.

Tempering and Secondary Heating: Undergoes a secondary heating phase at 200-300 ºC, effectively eliminating internal stress, enhancing toughness, and preventing brittle fracture.

2. Structural Design Enhancements

• Innovative Nail Tip Design:

Featuring a Triangular Pyramid Shape with a precise 30° tip angle, combined with a high-frequency quenching surface layer (hardness HRC60+), this design minimizes penetration resistance, boosting drilling efficiency.

Spiral Groove Engravings: Select models, such as textured cement nails, are equipped with spiral grooves, implemented through cutting-edge rolling technology. This significantly enhances mechanical gripping with substrates, elevating pull-out resistance by 30%.

• Ergonomically Designed Nail Cap:

With a Butterfly-shaped or Hexagonal Head, these caps maximize the stress distribution area, effectively dispersing hammering impact, thus preventing the nail cap from embedding into board surfaces, like gypsum board.

Anti-slip Diamond Rolling Patterns: The cap is crafted with diamond rolling designs to ensure a secure grip, reducing hand slippage risk when used with a rubber hammer.

A Comparative Analysis of Cement Steel Nails versus Ordinary Round Nails and Expansion Bolts Featuring Parameter Insights
Ideal for substrates like concrete, brick walls, granite, wood, thin steel plates, and hollow bricks. No pre-drilling is required, enabling direct application on high-hardness substrates.
Tensile Strength: Cement steel nails excel with a tensile strength of ≥ 800N/mm², comparing favorably against ordinary nails, which provide ≤ 400N/mm² and expansion bolts, typically ranging 500-1000N/mm². The efficiency of installation surpasses that of expansion bolts by 5 times.
Shear Strength: Cement steel nails boast a shear strength of ≥ 600N/mm², outperforming ordinary nails with ≤ 300N/mm², and often exceeding expansion bolts, which range between 400-800N/mm². This superior shear performance is indispensable for lateral stress applications.
Temperature Resilience: With a range from -40 ºC to 150 ºC, these nails surpass the capabilities of ordinary nails (-20 ºC to 80 ºC) and expansion bolts (-20 ºC to 120 ºC), proving ideal for outdoor and industrial environments.
Cost Efficiency: With a unit price of 0.1-0.3 yuan per nail, significantly lower than expansion bolts at 0.5-2.0 yuan per set, cement steel nails offer exceptional cost-effectiveness, outperforming other fastening solutions.
