Each of the ridge 100, the first railing connecting clip 200, the rafter 300, the second railing connecting clip 400, and the second railing 500 is coated with a coating film layer having weather resistance, corrosion resistance and durability .

At this time, the coating layer is formed by applying 20 to 40 parts by weight of an acrylic resin, 5 to 15 parts by weight of a pigment and 30 to 45 parts by weight of a solvent based on 100 parts by weight of a fluororesin by an immersion method or a spraying method .

When the amount of the fluorine-based resin is less than 100 parts by weight, the durability of the coating film decreases. When the amount of the fluorine-based resin exceeds 100 parts by weight, the appearance may not be smooth and the coating adhesion may be deteriorated. Any one selected from ethylene (PTFE), fluoroethylene propylene (FEP), tetrafluoroethylene perfluoroalkyl vinyl ether (PFA), polyvinylidene laden (PVDF) and homopolymer polyvinylidene fluoride can be used.

Ethyl acrylate or methyl methacrylate can be used as the acrylic resin, and it can provide excellent chemical resistance and weather resistance.

The pigment may be at least one selected from the group consisting of titanium dioxide, lithopone (ZnS + BaSO ₄ ), cobalt, aluminate and zeotropic pigment.

The solvent may be any one or more selected from among esters, ethers, ketones, glycols, and hydrocarbons.

The coating layer preferably has a structure in which 10 to 40 parts by weight of a surface modifier is added based on 100 parts by weight of the fluorine resin so as to have a stain resistance and a self-cleaning function. When the surface modifier is less than 10 parts by weight The surface modification effect is deteriorated. When the amount exceeds 40 parts by weight, the storage stability and workability of the paint may become poor.

The surface modifier preferably has a structure in which the main chain and side chain are substituted with an alkyl group, a methyl group or an ethyl group, but has a degree of polymerization in the range of 15 to 80 and a molecular weight in the range of 4000 to 10000. When the molecular weight is less than 4000, If the molecular weight is more than 10,000, the degree of curing may be reduced, and the physical properties such as chemical resistance and gloss may be deteriorated.

Here, the polyalkyl silicate used as the surface modifier does not contain a silanol group (SiOH) and is excellent in chemical resistance and storage stability. After the coating, the hydroxyl group which lowers the water contact angle due to moisture or rainwater in the air OH), it can exhibit a self-cleaning function and can block the penetration path of moisture, thereby increasing the service life.

Furthermore, each of the ridges 100, rafters 300, and ladies' boats 500 may be provided with an insulating filler member 600 for enhancing heat insulation and preventing condensation.

The insulating filler member 600 is prepared by mixing 60 to 75 parts by weight of the incombustible composite liquid with 100 parts by weight of the synthetic resin for mixing with one kind of heat insulating synthetic resin selected from the group consisting of polystyrene, polyolefin and polyurethane, A filling material is filled in the inner space of the ridge 100, the rafters 300, and the ladies' booth 500 and then foamed or formed into any one kind of heat insulating synthetic resin selected from polystyrene, polyolefin, and polyurethane (60) to 75 parts by weight of a nonflammable composition based on 100 parts by weight of the synthetic resin is mixed with a nonflammable composition liquid to enhance the nonflammability, and the mixture is extruded and then mixed with the ridge (100), the rafter (300) So as to have a fire-resistant performance in addition to the heat insulation property It can generate.
