3.0mm×40mm Color Galvanized Cement Nails – Product Introduction
1. Product Material
Our 3.0mm×40mm colorful galvanized cement nails are made of premium 45#/55# high-carbon steel (C45/C55 steel wire). Adopting integrated production processes including wire drawing, cold heading molding, overall quenching and tempering treatment, the nails feature a hardness of 40-53HRC and tensile strength above 800MPa. The precise heat treatment process balances high hardness and excellent toughness, ensuring the nails will not bend or break easily when hitting hard substrates.
2. Product Features
- Superior Penetration: Designed with 35° diamond sharp point, the nails can penetrate concrete, red brick, cement block and stone effortlessly, suitable for various hard wall construction scenarios.
- High Pull-out Resistance: Two rod types (smooth rod & vertical pattern rod) are available. The patterned rod increases friction with the base material, improving pull-out resistance by 45%-62% compared with ordinary nails for firm and stable fixation.
- Excellent Corrosion Resistance: Equipped with color galvanized passivation layer, the product passes 120-240 hours neutral salt spray test. It effectively resists rust and corrosion in humid indoor and outdoor environments, adapting to coastal and rainy overseas areas.
- Strong Toughness & Durability: Strict quenching and tempering process avoids brittle fracture, ensuring stable construction performance and long service life.
- Anti-slip Hammering Design: Thickened round flat nail head provides large bearing area, preventing slipping during hammering and avoiding surface damage to decorative plates.
- Distinct Appearance: Unique rainbow-colored passivation film facilitates on-site classification management and product identification.
3. Nail Rod Shape
- Smooth Straight Rod: Basic mainstream model for foreign trade, cost-effective, ideal for light-duty fixing projects and bulk wholesale.
- Vertical Knurled Pattern Rod: Upgraded anti-slip structure with dense vertical grooves on the rod body, greatly enhanced bite force with cement and masonry, preferred for overseas engineering orders.
- Unified design: Diamond chisel-shaped nail tip + thickened round flat nail head.
4. Surface Treatment
Adopts environmental three-valve chromium color galvanizing & passivation process with three-layer protection structure:
1. Bottom layer: 5-15μm electro-galvanized layer, serving as a sacrificial anti-rust metal layer.
2. Intermediate passivation layer: Colorful passivation film with self-repairing function, presenting uniform rainbow luster (green, yellow, blue mixed color), resisting mild acid and alkali erosion.
3. Surface sealing layer: Organic anti-oxidation sealing oil, improving salt spray resistance and preventing zinc layer abrasion during transportation.
Compared with common blue-white galvanized and blackened nails, our products have better weather resistance and longer anti-rust life for overseas long-distance shipping and outdoor use.
