Product Description

Professional application description of concrete nail

Cement steel nails are fasteners designed specifically for high hardness substrates such as concrete, brick walls, and stone. They achieve high strength and impact resistance through cold heading forming and quenching hardening processes, and are widely used in construction, decoration, and industrial fields. The following provides an explanation of its core features, technical parameters, typical application scenarios, and operational specifications:

1, Core Structure and Material Characteristics

1. Material and heat treatment

Main material: Made of medium carbon steel (such as C45 steel) or alloy steel (such as 40Cr), with a carbon content of 0.42% -0.50%, to ensure basic strength.

• Heat treatment process:

• Whole quenching: Heat the steel nail to 850-900 ºC and rapidly cool it to achieve a surface hardness of HRC52-58 (Rockwell hardness) and a bending strength of ≥ 1200MPa.

Tempering and tempering: secondary heating to 200-300 ºC eliminates internal stress, improves toughness, and avoids brittle fracture.

2. Structural optimization design

• Nail tip:

Triangular pyramid shape: with a tip angle of 30 °, combined with a surface high-frequency quenching layer (hardness HRC60+), it reduces penetration resistance and improves drilling efficiency.

Spiral groove engraving: Some models (such as textured cement nails) add spiral grooves to the nail body through rolling technology, enhancing the mechanical biting force with the substrate and increasing the pull-out resistance by 30%.

• Nail cap:

Butterfly shaped/hexagonal head: increases the stress area, disperses the hammering stress, and avoids the nail cap from being embedded in the surface of the board (such as gypsum board).

Anti slip rolling pattern: The hat top is designed with diamond rolling patterns, which, when used with a rubber hammer, can reduce the risk of hand slippage.

2, Technical parameters and performance comparison

[Table]
Comparison of Advantages of Cement Steel Nails, Ordinary Round Nails, and Expansion Bolts with Parameter Parameters
Suitable for substrate concrete, brick walls, granite wood, thin steel plate concrete, and hollow bricks. No pre drilling is required, and high hardness substrates can be directly injected
Tensile strength ≥ 800N/mm ² ≤ 400N/mm ² depends on specifications (usually 500-1000N/mm ²). The strength is close to that of expansion bolts, but the installation efficiency is increased by 5 times
Shear strength ≥ 600N/mm ² ≤ 300N/mm ² depending on specifications (usually 400-800N/mm ²). Shear performance is superior to expansion bolts and suitable for lateral stress scenarios
Temperature resistance range -40 ºC to 150 ºC -20 ºC to 80 ºC -20 ºC to 120 ºC. The high temperature resistance performance is better than ordinary nails and suitable for outdoor/industrial environments
The cost of a single nail is 0.1-0.3 yuan/piece, 0.02-0.05 yuan/piece, 0.5-2.0 yuan/set, which is lower than that of expansion bolts and has outstanding comprehensive cost-effectiveness
