Black zinc cement nails are made from carefully selected high-carbon steel, forged and quenched in one piece, specifically designed for anchoring and fixing to hard surfaces such as concrete, red brick, stone walls, and precast concrete slabs.
Widely suitable for all construction scenarios including home decoration, plumbing and electrical wiring, wall fixing, carpentry construction, door and window installation, and engineering pre-embedding. They penetrate hard walls without bending, chipping, or splitting, locking firmly in place with a single blow. They are an essential fastener for construction sites.
1. High-carbon steel, integrally quenched, providing superior hardness and impact resistance; will not bend, chip, or break even under heavy impact.
2. Black zinc anti-corrosion and rust-proof coating, long-lasting durability and rust prevention. The uniform and dense surface offers excellent resistance to moisture, acids and alkalis, and oxidation.
3. Precision one-piece molding process ensures stable support and prevents nails from falling out. The large-headed nail distributes force evenly upon impact, preventing slippage and denting. The nail body adheres closely to the wall, ensuring a firm and secure fit. The sharp, tapered tip minimizes resistance during penetration, reducing effort and significantly improving construction efficiency.
Tianjin Lituo has been deeply involved in the fastener industry for many years, possessing its own fully automated closed-loop production line for steel rolling, forging, quenching, blackening, galvanizing, and finished product packaging. We offer factory-direct prices, eliminating distributor markups. For large-volume projects and long-term wholesale orders, our cost advantage far surpasses that of our competitors.
All batches undergo hardness testing, bending resistance testing, and salt spray rust resistance durability testing. Each nail undergoes strict quenching process control to eliminate soft, bent, and easily rusted defective nails. Uniform specifications and precise tolerances ensure consistent and stable hammering, significantly reducing construction waste and rework costs.
We support customized lengths, nail head specifications, and different surface treatments such as blackening and galvanizing. We also offer OEM/ODM services with custom logo labeling, adapting to irregular projects and special construction conditions.
We simultaneously supply a full range of building fasteners, including nails, ceiling accessories, expansion bolts, and wallboard nails, providing a one-stop shop for all your construction consumables. Our professional technical team provides pre-sales selection guidance and rapid after-sales response. Long-term partners can receive free samples and construction-related technical support.
