Product Description

Expert Overview: The Versatility and Strength of Concrete Nails

Cement steel nails are meticulously engineered fasteners, crafted to conquer the challenges of high-hardness substrates like concrete, brick, and stone. These nails boast remarkable strength and impact resilience, thanks to advanced cold heading forming and quenching hardening techniques. Widely embraced in construction, decoration, and industrial sectors, these nails are the epitome of durability and reliability. Below, we delve into their distinctive core features, cutting-edge technical parameters, practical application scenarios, and precise operational guidelines:

1, Core Structure and Material Characteristics

1. Material and Heat Treatment Innovations

Constructed predominantly from medium carbon steel (e.g., C45 steel) or robust alloy steel (e.g., 40Cr), these nails boast a carbon content between 0.42% -0.50%, ensuring exceptional foundational strength.

• Specialized Heat Treatment Process:

• Comprehensive Quenching: Elevate the steel nail temperature to 850-900 ºC, followed by rapid cooling to secure a surface hardness of HRC52-58 (Rockwell hardness) and achieve a bending strength of ≥ 1200MPa.

Tempering Process: A secondary heat treatment at 200-300 ºC mitigates internal stress, enhances toughness, and prevents brittle fractures.

2. Cutting-edge Structural Optimization Design

• Innovative Nail Tip Design:

Triangular Pyramid Configuration: Featuring a precise 30° tip angle and fortified with a surface high-frequency quenching layer (hardness HRC60+), this design significantly reduces penetration resistance and amplifies drilling efficiency.

Spiral Groove Technology: Select models (e.g., textured cement nails) integrate spiral grooves into the nail body using advanced rolling technology, bolstering the mechanical grip with the substrate and enhancing pull-out resistance by up to 30%.

• Enhanced Nail Cap Design:

Butterfly-shaped/Hexagonal Head: Maximizes stress distribution, mitigates hammering-induced stress, and prevents the nail cap from embedding into surfaces such as gypsum boards.

Anti-slip Rolling Pattern: A diamond-patterned hat top, designed for use with a rubber hammer, reduces hand slippage risk during operation.

2, Technical Parameters and Performance Comparison

[Table]
A Comprehensive Comparison of Cement Steel Nails, Ordinary Round Nails, and Expansion Bolts Based on Parameter Metrics
Suitable substrates include concrete, brick walls, granite, wood, thin steel plates, and hollow bricks. These nails require no pre-drilling and can be directly driven into high-hardness substrates.
Tensile Strength: Achieves ≥ 800N/mm², compared to ≤ 400N/mm² of others, approximating expansion bolts while enhancing installation efficiency fivefold.
Shear Strength: Reaches ≥ 600N/mm², surpassing the typical ≤ 300N/mm² of alternatives, excelling in scenarios demanding superior lateral stress performance.
Temperature Resistance Range: Spans from -40 ºC to 150 ºC, outclassing ordinary nails with -20 ºC to 80 ºC range, ideal for outdoor and industrial environments.
Cost Efficiency: With a unit cost of 0.1-0.3 yuan/piece, significantly less than expansion bolts at 0.5-2.0 yuan/set, offering unparalleled value and cost-effectiveness.
