Other embodiments of the present invention are all the same as the above-described embodiment, but only in the form of a decoration.

As shown in FIG. 4, the decorative body 40b has a concave part 42 having a lateral cross-sectional shape of a '∩' shape, and a decorative part 44 having a 'T' shape on an upper surface of the concave part 42. ) Is connected and has a long curvature along the longitudinal direction. In other words, the outer shape of the decorative body 40b is formed in a waveform when viewed from the front to give the appearance a beautiful appearance, and a more solid advantage can be obtained by integrally fixing the upper ends of the vertical rods 30.

As shown in (a) of FIG. 6, the decorative body 40b has a length corresponding to the length of the plurality of vertical rods 30 vertically coupled to the upper and lower pipes 20a and 20b. The mouth part 42 and the decoration part 44 are equally continuous in the longitudinal direction, or as shown in (b) of FIG. 6.

As shown in FIG. 2 (d), the vertical rod 30 is formed by hot dipping surface treatment to form a hot plated layer P on the entire surface thereof, and the hot plated layer P. It is preferable to form a powder coating layer (C) by powder coating on the layer) so that corrosion does not occur. Of course, the upper and lower pipes 20a and 20b may also be formed by forming a molten plating layer P and a powder coating layer C.

Here, the upper and lower pipes (20a, 20b) and the vertical rods 30 are made of a material made of steel, because it is very cheap in terms of price than stainless steel.

In the above description of the 'melt plating', after removing impurities such as dust, oil, rust, etc. attached to the steel to be plated, the plated material (steel material) is deposited on the molten zinc at about 450 ° C. And zinc react with each other to form an alloy layer of iron and zinc, and a pure zinc layer is coated on the alloy layer. Zinc forms an alloy layer with iron and is attached to form a protective film of iron to protect iron and It is a surface treatment method that has excellent corrosion resistance at the expense.

In addition, the life of the hot-dip plating is more than 20 to 25 years even in urban areas, especially in coastal areas. When the hot-dip galvanizing layer (P) is used, iron and zinc are combined to form an alloy at the boundary, and thus anticorrosive effect can be obtained. Unlike the general coating method, even though a part of the hot dip is damaged and the surface of the steel is exposed to the atmosphere, zinc can be sacrificially and cathodic to prevent corrosion of the steel.

In addition, as shown in (d) of FIG. 2, when the above-mentioned hot dip plating is performed, the hot dip coating layer P is formed on the entire inner surface of the vertical rod 30, that is, where the anticorrosive effect does not reach other coating methods ( For example, even a corner can be realized by the hot dip galvanizing layer (P).

For reference, surface treatment methods include electroplating, chemical plating, thermal spraying, evaporation, compression, infiltration, etc., but it is known that 'hot dip galvanizing' is the most economical and long-term corrosion method.

The above-mentioned 'powder coating' is simply a method of making synthetic resin into powder and painting it on the metal surface, melting and finishing it at high temperature, and the powder coating is excellent in corrosion resistance, adhesiveness, durability, etc. It is widely used to make products.

For reference, the anticorrosion effect is to prevent the metal from being eroded by the chemical action of the corrosive substance. The anticorrosion effect refers to a method of covering the surface of the metal with another chemically stable substance so as not to contact the corrosive substance. .

The upper and lower pipes 20a and the vertical rods 30 are hot-dip galvanized layers on the entire surface of the upper and lower pipes 20 by the hot-dip surface treatment method in which the coupling holes 21a, 21b and the expansion holes 22, 33 are formed in advance. After forming P), the powder coating layer (C) is formed in the order of forming the powder coating layer (C) by the powder coating on the hot dip plating layer (P), so that the coupling holes (21a) (21b) and the expansion holes (22) (33). Corrosion does not occur.
