In civil engineering, carpentry, and construction, a nail is a sharp, pointed piece of hard metal (usually steel) used to hold things like wood inplace.Hammers drive nails into objects. There are also electric nail guns and gas nail guns.Nails hold objects in place by their own deformation and by the force of friction.

Uses:furniture making, sofa, wooden case, and all kinds of wood products.

3,code nail

Usage:Used for sofa, chair, sand and leather in furniture manufacturing industry.The upholstery industry is used for ceiling and sheet metal, and the wooden caseindustry is used for outer sheet metal.

4,cement steel nail

In appearance and round nail is very similar, the head is slightly thicker.Butcement steel nails are made of high quality steel, which have the advantages ofhardness and bending resistance, and can be nailed directly into concrete and brick walls.Common specifications are 7~35mm.

Used for binding paper documents, there are generally two kinds of iron or copper,plated with nickel or nickel zinc alloy to prevent rust.


The bolts commonly used in decoration engineering are mainly divided into plasticand metal, which are used to replace the embedded bolts.Suitable for all kinds of wall, ground anchoring building accessories and objects.

13, nail straight

Straight nailing use: upholstery of the three - plywood, slats.Furniture manufacturing of wooden joint with rattan and other steel nails: made of high quality 45#carbon steel, unique design, reasonable structure, exquisite appearance,suitable for light wood keel connection.

14.Special steel nails

Ringnails are mainly used for fiberboard and gypsum board.

Concretesteel nail is used for cement wall, ground and surface material connection.Decorativenails are used for soft bale fastening.
