How to choose the wrought iron gate? This article will tell you how to avoid buying poor quality wrough iron doors.
Rencetly a friend told me that he bought a wrought iron guardrail, just because the price is cheap, he have to buy paint and respray the gate again. Most of the people introduces how good their product is, but does not teach people how to choose iron gate to aviod buying poor quality, let me brief say:
1.Don’t be greedy for petty bargains! High quality and low price are just marketing methods. From ancient times to the present, you get what you pay for. The price of radish can never buy ginseng. The actual production material is quite different from the original style material, hollow pipe, not galvanized...
2.Because it is an outdoor customized product, follow up the most important step of hot-dip galvanizing in the production process, and provide photos after hot-dip galvanizing (the product after hot-dip galvanizing is white with zinc slag hanging, and the surface of the product is uneven) . As for how to distinguish hot-dip galvanizing, cold-dip galvanizing and galvanizing, follow me, the next article will elaborate.
3.Surface paint selection: self-drying paint, baking paint! Generally, forged iron art uses self-drying paint, and the spraying process is consistent with the automotive topcoat process. Of course, there are requirements for the number of primers and topcoats. If the requirements are not high, one primer and one topcoat will enough but will have a rough surface! High-demand iron art will be polished and repaired primer for many times. Baking paint is mainly used for simple cold-galvanized pipe products with only horizontal and vertical pipes, or simple or complex non-galvanized wrought iron for indoor use. The main reason is that the labor cost is low, and the possibility of rusting is small when the surface is intact, and it is easy to rust after damage. After the hot-dip galvanized iron coating is damaged, the zinc layer can well protect the steel from corrosion.Even after the coating is bumped, it is easy to repair. While the baking paint coating is damaged, it is basically impossible to repair it well, and the coating will fall off in lumps.
4.Installation: Try to use the assembly method to avoid damage to the zinc layer by on-site welding. If it is unavoidable, it is necessary to do antirust treatment on the welded joints, and the manufacturer can distribute professional antirust primer and topcoat. It can also be sealed with weather-resistant seal ant according to the site conditions.
