2 “× 3.4 mm straight fluted cement nail product parameters (material, characteristics, surface treatment, packaging, application scenarios)
I. Basic product specifications
Specification: The length is 2 inches (50mm), the thread diameter is 3.4mm, and the nail body is straight (vertical grain), which belongs to the national standard high-strength hard cement nail and is a common hardware accessory for building fastening.
II. The core material
The mainstream material is high-quality 45# high carbon steel, and some export high-end batches are refined with 55# carbon steel. In the production process, the whole quenching+tempering heat treatment has moderate carbon content, giving consideration to high hardness and toughness, which is different from the soft material of ordinary nails, and can strongly penetrate hard substrates and is not easy to bend and break.
III. Product features
–High hardness and strong penetration: after heat treatment, the hardness can reach HRC40-HRC50, which is far higher than that of ordinary nails. It can be directly nailed into hard bases such as concrete, brick walls and cement mortar layers without drilling holes in advance.
–Straight anti-slip fastening: the nail body is designed with even straight lines, which greatly increases the friction between the nail body and the base material. After nailing, the bite is tight, and it is not easy to loosen and pull out, and the fixation stability is far better than that of smooth cement nails.
–Toughness and fracture resistance: abandoning the pure brittle-hard process, it has both hardness and toughness after quenching and tempering, and it is not easy to break the head and nail during knocking construction, which is suitable for manual and light pneumatic tools.
–Strong specification adaptability: 2-inch length with 3.4mm moderate wire diameter, balanced thickness and length, bearing capacity and construction convenience, and high versatility.
–High cost performance: controllable raw material cost, low mass production cost, strong durability, suitable for mass use in large-scale projects and export standards.
IV. The surface treatment method (general export)
According to the needs of exporting countries and customers, it is divided into three mainstream treatment processes, and the anti-corrosion and anti-rust level is gradually improved:
–Natural color polishing (black and bright surface): basic treatment method, polishing and deburring, no coating, retaining the original color of steel, general rust prevention performance, suitable for export in dry areas and short-term indoor engineering, with the lowest price.
–Electro-zinc plating (white zinc/blue-white zinc): the most mainstream export treatment method, with uniform and bright zinc coating on the surface, anti-oxidation and anti-corrosion after passivation treatment, which can cope with conventional wet environment and meet most common foreign trade order standards.
–Colored zinc plating (multicolored zinc plating): High-end export technology, with multicolored luster on the surface, thicker zinc coating, stronger adhesion, excellent acid and alkali resistance and corrosion resistance, suitable for export in coastal high-humidity and rainy areas, and greatly prolonged rust-proof life.
V. Export packaging methods (foreign trade standards)
Standardized export packaging with “small package+outer box reinforcement” is adopted, which is suitable for long-distance transportation by sea and land, and can prevent extrusion and scattering, and can customize customer LOGO and label:
–Internal packaging: conventional 500g/ box, 1kg/ box hardcover (cardboard box/plastic box). The box body is printed with product specifications, materials, quantity and origin, and sub-packaging specifications such as 250g and 1bt can also be customized according to customer requirements.
–Outer packaging: Five-layer thickened corrugated export cartons are uniformly adopted, each carton has a fixed net weight (mainly 25kg/ carton, 20kg/ carton), and the carton sealing tape is reinforced and the corners are protected to prevent transportation damage.
–Customized packaging: We can provide neutral English packaging, customer-branded packaging, woven bags in bulk and other solutions to meet the different needs of cross-border e-commerce, wholesalers and project procurement.
VI, the core application scenarios
With its high hardness and strong fastening, it is widely used in architectural decoration, engineering fastening, home installation and other scenes, and is a special fastening accessory for hard base materials;
–Building decoration works: indoor and outdoor wall fixing, cement mortar layer auxiliary material fixing, temporary positioning of wall keel, and fastening of simple components on site.
–Home hardware installation: the skirting line, door cover and window cover are fixed, and the wall decorative board, gypsum board and aluminum-plastic board are fixed at the grass-roots level.
–Fixing of water and electricity pipelines: fast fixing of water pipe clamps, conduit supports and trunking on brick walls and concrete walls.
–Industrial and outdoor fastening: outdoor wall fixing of small hardware fittings, signs and brackets, positioning and reinforcement of light equipment base.
–General scene of foreign trade: it is suitable for overseas home improvement, infrastructure and maintenance projects, and is a standardized fastening hardware consumable used worldwide.
