Product Description

Expert Overview: Comprehensive Application of Concrete Nails

Cement steel nails are precision-engineered fasteners, perfectly crafted for securing into the toughest substrates like concrete, brick, and stone. Through advanced cold heading and quenching hardening processes, these nails boast exceptional strength and formidable impact resistance, making them indispensable across construction, decoration, and various industrial sectors. Below is an in-depth exploration of their key features, technical specifications, typical usage scenarios, and operational guidelines:

1. Core Structure and Material Characteristics

1. Material and Heat Treatment

Primary Composition: Crafted from medium carbon steel (e.g., C45 steel) or robust alloy steel (such as 40Cr), with a precise carbon concentration of 0.42% - 0.50%, ensuring unyielding core strength.

• Heat Treatment Process:

• Full Quenching: The nails are meticulously heated to a precise 850-900 ºC, then rapidly cooled to attain a surface hardness of HRC52-58 (Rockwell hardness) and bending strength of ≥ 1200MPa.

Tempering and Annealing: By reheating to 200-300 ºC, internal stresses are skillfully alleviated, enhancing ductility and preventing brittle fracturing.

2. Optimized Structural Design

• Nail Tip:

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

Spiral Groove Engraving: Select models incorporate spiral grooves via rolling technology, boosting substrate mechanical grip and enhancing pull-out resistance by an impressive 30%.

• Nail Cap:

Butterfly/Hexagonal Head: Expanded stress area diffuses hammering impact, preventing nail cap embedding into brittle surfaces like gypsum boards.

Anti-Slip Rolling Pattern: The cap's diamond-etched design, when used alongside a rubber hammer, significantly reduces hand slippage risk.

[Table]
Advantage Comparison: Cement Steel Nails, Ordinary Round Nails, and Expansion Bolts with Parameter Metrics
Perfect for substrates like concrete, brick walls, granite wood, and thin steel plates. They allow direct injection into high-hardness substrates without pre-drilling.
Tensile Strength: An impressive ≥ 800N/mm² compared to ≤ 400N/mm² in others, with installation efficiency outpacing expansion bolts by 5 times.
Shear Strength: Achieves ≥ 600N/mm², surpassing ≤ 300N/mm² in competitors, ideal for lateral stress demands, outshining expansion bolts.
Temperature Resistance: Withstands -40 ºC to 150 ºC, outperforming the -20 ºC to 80 ºC range of ordinary nails, ideal for harsh outdoor/industrial conditions.
Cost Efficiency: At 0.1-0.3 yuan per nail, compared to 0.02-0.05 yuan per ordinary nail and 0.5-2.0 yuan per expansion bolt, offering superior cost-effectiveness.
