A quick look at the core information of 5-inch common nails

-Key points: 5-inch (about 125mm) nails are usually made of low carbon steel, with polished/galvanized surfaces, featuring flat caps, round rods and diamond tips. The packaging is mainly made of cartons and plastic bags, which are widely used in construction, carpentry, furniture and packaging.

I. Material

-Mainstream material: low carbon steel Q195/Q215/Q235, with good toughness and bending degree ≥ 90, suitable for carpentry and general architectural scenes.
-Other materials: some high-end scenes use medium carbon steel, which has higher hardness but higher cost.

Second, the surface treatment

Processing method Appearance performance cost Applicable scenario
Polished bright silver, bright and clean, rust-proof foundation, low indoor dry environment, furniture assembly
Galvanized silver-gray rust prevention is better in moderate and humid environment and outdoor light exposure.
Hot dip galvanized silver gray (slightly rough) strong rust resistance, weather resistance, long-term outdoor exposure, building structure
Where painting/painting is needed in the subsequent process of phosphating dark gray to enhance the adhesion of the coating.
The paint has good color decoration, low decorative requirements for rust prevention and color matching with the base material.

Third, the characteristics

-Structure: flat cap, round rod, diamond tip, easy to knock, stable positioning and low drilling resistance.
-Mechanics: Low carbon steel has good toughness and can withstand certain bending without brittle fracture.
-Technology: The wire rod is processed after drawing, with high dimensional accuracy and smooth surface.
-Specification: about 4.5mm in diameter and 125mm in length, suitable for most common scenes.

Fourth, packaging

-Conventional packaging: inner plastic bag+outer carton; Common specifications are 5kg/ box, 25 boxes/box or 25kg/ box in bulk.
-Customized packaging: 0.5-1kg PVC bag, 1–5kg paper box, gunny bag, etc., which can be adjusted as required.
-Marking: marking specifications, materials, surface treatment, weight, quantity and other information.

V. Application

-Building decoration: wood structure fixing, wall keel installation, door and window frame assembly.
-Woodworking furniture: furniture assembly, plate splicing, mortise and tenon reinforcement.
-Packaging and transportation: wooden cases/wooden pallet binding, cargo fixing.
-Others: bamboo products, fixing of common plastic parts, sand turning of earth walls, maintenance of farm tools, etc.

Sixth, suggestions for purchasing

-Indoor drying, selective polishing; Wet/outdoor selective zinc plating/hot dip galvanizing; It needs to be painted and phosphatized.
-Q235； is selected for the load-bearing scene; For general use, choose Q195 to balance cost and performance.

Do you need me to organize this information into a purchasing specification table that can be used directly (including the corresponding selection of materials, surface treatment, packaging, quantity and applicable scenarios)?
